SQL Azure – TSQL Script – Address table

Designed to be used in conjunction with previous post Persons table. Will allow for multiple addresses for individuals. Country field to draw from Country table but I would not foreign key the value to country table identity but reference it to the actual name. Personal naming convention to name foreign keys after the pkid[tablename] I find that works well for me and seems very logical. I have a large system at work which simply names foreign keys fkid can be difficult to find what table it refers to resulted in me thinking hard about a naming convention for foreign keys.
I like pkid[tableprefix]. I usually leave it at that have expanded below because its a single script and may or may not be used with an actual persons t0001 table.

SQL Azure – TSQL Script – Country File Lookup Table (with data accurate November 2020)

I’ve written about this in a previous post. I had a client that has customers all over the world and I wanted to align and enforce validation of the correct countrys as stock and product may need to be posted. Its unusual to have an attribute that is both finite and universal between systems – The list is taken from the international recognized ISOcode standard.(November 2020)

I use this as a lookup field in addresses for people

SQL Azure – Export Individual Tables Using SQL Server Management Studio

Connect to SQL Azure through SQL Server Management Studio

Select the database that contains the table you wish to script

Right click on the database and select Generate Scripts

The Generate Scripts dialog should appear choose

Choose Objects
Select specific database objects

Hit Next and set the location of where you wish the file to go

Review the summary dialog to ensure you have everything correct

Next you want to decide whether you want to include data or not in the script file

Hit the advanced button and scroll down to Types of data to script

If you are wanting data to be included select schema and data

Hit the Next button and review your configuration

Hit Next and it will start the process of exporting your table with or without data

The dialog will update to show status of script generation

You will now be able to navigate to the script and open it in an editor of your choice to double check that things look ok.

Here I show a script that includes data – note you can’t see all of the insert information because the script is rather wide but I assure you it is there at the bottom.

SQL Azure – TSQL User Defined Function – Pull out Long Dates from NVARCHAR(MAX)

Dates that match the pattern 2 numbers a single space the month a single space then a 4 digit year this will be good for any dates following this format from 1000 AD to 9999AD with a NVARCHAR(MAX) field note it will only pick up the last date in a text field.

SQL Azure – TSQL User Defined Function – Pull out money from NVARCHAR(MAX)

I think this one is pretty dirty but here goes.

Again it was adapted from StackOverflow thread
How to get part of string that matches with regular expression in SQL Server

Continuing the theme of identifying substrings in NVARCHAR(MAX) field here is a set of Functions that can be used identify and separate out money in an email body which has been uploaded into a NVARCHAR(MAX) field. looks for the pattern of 2 numbers after a dot and certain numerals before a dot and steps down from hundreds of thousands of pounds to tens of pounds. Note the order is important of the final query as each shorter pattern is a subset the next longer pattern.

First important to strip out the commas in the body as this will skip any currencies which have been formatted with commas.

UPDATE T032email
SET body = REPLACE(body,',','');

WARNING It should be noted that this is very unoptimised code and even on small sets combining the functions in a nested ISNULL SQL really takes time to run.

Firstly a function that looks for the pattern 100000.00 ie 999k to 100k.

    set @loop=@loop+1
    end
Return @retemoney2
END

And then here is the quite horribly inefficient query that can be used to run all functions and seems to do the job.

You know your searchstrings better than me but any text with multiple decimal substrings will be an issue!!!

Which is still a few million times quicker than any person!

SELECT dbo.T032email.pkid,
ISNULL(dbo.ReturnMoneyDecimal6(dbo.T032email.body),
	ISNULL(dbo.ReturnMoneyDecimal5(dbo.T032email.body),
		ISNULL(dbo.ReturnMoneyDecimal4(dbo.T032email.body),
			ISNull(dbo.ReturnMoneyDecimal3(dbo.T032email.body), dbo.ReturnMoneyDecimal2(dbo.T032email.body)
				)))) as money4 from T032email;

SQL Azure – TSQL User Defined Function – Cleaning a Field of Specified Characters

Stack overflow sourced, adapted and personally tested code
How to strip all non-alphabetic characters from string in SQL Server

In an earlier post I was having issues as some email addresses I was pulling out from a field were captioned in <> using the following will remove those characters prior to identifying string patterns..

Remember this pulls them out and then compacts the resulting string this may or many not be what you are looking for. I have adapted from the Stack Overflow discussion to include characters I don’t want rid of.

CREATE Function [dbo].[RemoveNonAlphaCharacters](@Temp nvarchar(max))
Returns nvarchar(max)
AS
Begin

    Declare @KeepValues as nvarchar(50)
    Set @KeepValues = '%[^a-z0-9/@ £$+=?.\!]%'
    While PatIndex(@KeepValues, @Temp) > 0
        Set @Temp = Stuff(@Temp, PatIndex(@KeepValues, @Temp), 1, '')

    Return @Temp
End

And running the example code we get..

SELECT dbo.RemoveNonAlphaCharacters('abcdefghijklmnopqrstuvwxyz1234567890 !"£$()_+=-{}[]:@~;\|<>?./') as txtCorrected

We get

WARNING Please note ^ % & and * ‘ ” – are reserved TSQL characters and including them in the function appears to break the logic that I wish to see in the pattern replacement.

SQL Azure – TSQL User Defined Function – Separate multiple emails from NVARCHAR(MAX) field

Stack overflow sourced, adapted and personally tested code
Extract email address from string using tsql

A continuation of working with strings in TSQL specifically linked to emails.

Firstly create the following Function

CREATE FUNCTION [dbo].[fnFindPatternLocation]
(
    @string NVARCHAR(MAX),
    @term   NVARCHAR(MAX)
)
RETURNS TABLE
AS
    RETURN 
    (
        SELECT pos = Number - LEN(@term) 
        FROM (SELECT Number, Item = LTRIM(RTRIM(SUBSTRING(@string, Number, 
        CHARINDEX(@term, @string + @term, Number) - Number)))
        FROM (SELECT ROW_NUMBER() OVER (ORDER BY [object_id])
        FROM sys.all_objects) AS n(Number)
        WHERE Number > 1 AND Number <= CONVERT(INT, LEN(@string))
        AND SUBSTRING(@term + @string, Number, LEN(@term)) = @term
    ) AS y);

Then create a View of what you are interested in as follows.. Note here I am taking out the carriage return as my subsequent query doesn’t like them and in emails they frequently exist.

CREATE VIEW [dbo].[v001] as SELECT pkid, REPLACE(body, CHAR(13) + CHAR(10),' ') as body1 from t001email

Then run the newly created View through a query.

SELECT pkid, body1, pos, SUBSTRING(body,beginningOfEmail,endOfEmail-beginningOfEmail) AS email
FROM v001
CROSS APPLY (SELECT pos FROM dbo.fnFindPatternLocation(body1, '@')) AS A(pos)
CROSS APPLY (SELECT CHARINDEX(' ',body1 + ' ', pos)) AS B(endOfEmail)
CROSS APPLY (SELECT pos - CHARINDEX(' ', REVERSE(SUBSTRING(body, 1, pos))) + 2) AS C(beginningOfEmail)

Couple of things here
Multiple emails will be picked out and placed as separate records so if there a string that reads

This is a sentence with two emials first@gmail.com and a second second@gmail.com

it will return
first@gmail.com
second@gmail.com

If an email starts the field then this will NOT work after finding the @ symbol it will count forward and fail to find a space and so set space before to Null it will then return just the domain of the email. I will be looking to fix this at some point.

Secondly if the emails within the field contain contiguous special html characters such as < or > these will be picked up and inculded as if they are part of the email addresses.

We can fix this by scanning through the varchar(max) field and stripping out special characters.

NOTE : If you are working with email bodies carriage returns will also screw up the above query in which case consider running the field through some kind of replace view with similar syntax as

CREATE VIEW v002 as SELECT pkid, REPLACE(body, CHAR(13) + CHAR(10),' ') as txtBodyWithoutReturns from t001email

SQL Azure – TSQL User Defined Function – Separate Defined Length String from NVARCHAR(MAX) Field

Stack overflow sourced, adapted and personally tested code
How to get part of a string that matches with a regular expression

The following function arose out of a desire to find Eplanning Scotland planning references numbers which follow the format of 9 numerals a dash and then 3 numerals within a NVARCHAR(MAX) field type. The characteristics of the string was that it is always the same length.

In SSMS select the New Query button

Create function [dbo].[ReturnEplanningNumberFull](@fieldtosearch as nvarchar(max))
 Returns nvarchar(13)
 as
 begin
 declare @length as int 
 declare @loop as int
 declare @reteplan as varchar(13)
 set @loop =1
 set @length = len(@fieldtosearch)

 while @loop<=@length-12
    begin
    if exists(select 1 where substring(@fieldtosearch,@loop,13) like '[0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][-][0-9][0-9][0-9]')
        set @reteplan = substring(@fieldtosearch,@loop,13)
    set @loop=@loop+1
    end
Return @reteplan
end

And then to create a View using this you can write something like ;

CREATE VIEW v026eplanrefs AS 
SELECT dbo.THETABLE.pkid, 
dbo.ReturnEplanningNumberFull(dbo.THETABLE.FIELDCONTAINSREFERENCE) as eplanno 
FROM dbo.THETABLE;

I subsequently altered this to identify the first 9 digits as this is sufficent to uniquely identify eplanning records.

CREATE function [dbo].[ReturnEplanningNumberShort](@fieldtosearch as nvarchar(max))
 Returns nvarchar(9)
 as
 begin
 declare @length as int 
 declare @loop as int
 declare @reteplanshort as nvarchar(9)
 set @loop =1
 set @length = len(@fieldtosearch)

 while @loop<=@length-8
    begin
    if exists(select 1 where substring(@fieldtosearch,@loop,9) like '[0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9]')
        set @reteplanshort = substring(@fieldtosearch,@loop,9)
    set @loop=@loop+1
    end
Return @reteplanshort
end

SQL Azure – Reset Primary Key Identity/Index to Zero after Deleting all records

I was faced with a situation where I needed to set up an index for widgets but I wanted those to start at zero. I made some attempts to import information and deleted those records from the table several times and was faced with a situation where users might see the index occasionally. As a result I wanted the index to start from 1 and at least at the start go up to the approximate number of widgets.

Its a quick search using google to get this but wanted to reset the identity on a blank table.

In SSMS / navigate to the database and open a new query window

DBCC CHECKIDENT (dbo.t001table, RESEED,0);
GO

MS SQL Azure – Conditional Computed Column Definition Using CASE

Setting aside for the moment the rights and wrongs of using persisted columns sometimes it is just a great way to add some automation to your database and make it clearer for the user.

But what if you want to add a conditional computed column for rows based on another value within that row. Here’s something I worked out.

ALTER TABLE ProjectManagement
ADD FutureorPast AS CAST
(
CASE
WHEN TargetDate > GetDate() or TargetDate is Null THEN 'FUTURE' WHEN TargetDate <= GetDate() THEN 'PAST'
ELSE ''
END as nvarchar(6)
)
GO

MS SQL Azure – CONCAT_WS Working with addresses and nicely formatting separated fields

I recently came across a very useful function that I am told was introduced in SQL Server 2017 called CONCAT_WS
I have never used it in any other application other than SQL Server I hope it exists in MYSQL and PostgreSQL

This will join together a series of fields with chosen separators and by combining it with NULLIF can be used to remove spaces and format address nicely.
For applications that will at some point need addresses either for post or for information this function allows the display of addresses in a format the most clearly reflects the requirements of most postal systems. Needless to say it is likely that most of my systems will at some point transition to the use of this function.

Here is a link to Microsofts documentation on the function CONCAT_WS

Firstly let me review what I am starting to standardise on with regard to address fields which should be a balance between enough detail to store any address on the planet but not so much that it is overly complicated. I’ve expanded their descriptions somewhat. In my experience someone will have created an excel spreadsheet to start the process of recording information, often they standardise on column names such as address01/02/03 etc. If that breakdown exists then I have indicated the fields that I would normally expect to map those fields too.

flatno-buildingdivision
houseno-buildno
housename-buildname
streetfirst-address01
streetsecond
locality-address02
towncity-address03
stateoradminlocality
postcode-address04
country-address05

And here is an example of the code implemented.

CREATE VIEW v001formattedaddress AS SELECT pkid,
email,
CONCAT_WS(' ',NULLIF(dbo.t001addresstable.firstname,' '), NULLIF(dbo.t001addresstable.surname,' ')) AS fullname,
CONCAT_WS(CHAR(13) + CHAR(10),
NULLIF(dbo.t001addresstable.flatno, ' '), 
NULLIF(dbo.t001addresstable.houseno,' '), 
NULLIF(dbo.t001addresstable.housename,' '),
NULLIF(dbo.t001addresstable.streetfirst,' '),
NULLIF(dbo.t001addresstable.streetsecond,' '),
NULLIF(dbo.t001addresstable.locality,' '),
NULLIF(dbo.t001addresstable.towncity,' '),
NULLIF(dbo.t001addresstable.stateoradminlocality,' '),
NULLIF(dbo.t001addresstable.postcode,' '),
NULLIF(dbo.t001addresstable.country,' '),
REPLICATE('-', 30) ) AS addressconcat FROM dbo.t001addresstable;

Additionally on reflection for a recent project I made up a list of countries that covers most in the world. For my project I put an include field next to them to allow system administrators to include whether these would be visible in the drop down. Clearly while overtime more and more countries may be added there I would expect it to be years or possibly decades before some of the values of the smaller nations are needed. (For my particular application anyway)

I standardised on the following the 2 digit codes are the ISO Country code standard

AD Andorra

MS SQL Azure – Creating contained users – SQL Authentication – DACPAC and BACPAC import

In every database engine it is important to create logins that enforce security around your database and that can be maintained.
Additionally if you are working for a client you may wish to transfer this database at some point in the future to the client.

In SQL Azure users can be created against the master database in the instance and the role can then be transferred to individual databases.

Fine but there may be circumstances where you want to isolate roles to individual databases so that when they are moved the roles move with them and are not left in the master database.
The following sets out an example of how to set up a Contained database in SQL Azure along with something extra you have to think about when re-importing to an SQL Server instance.

Using your sysadmin account connect to the database you wish to add a user to and run;

CREATE USER rocketengineapplication WITH PASSWORD = 'bluedanube';
ALTER ROLE db_owner ADD MEMBER rocketengineapplication;

Now developers could use this password and username to login to the database and do most of what is required without having any privileges to the SQL Server and if you ever transfer the database the role will pass with the database.

Here is a link to built in database roles
SQL Database Roles

Secure a single or pooled database in SQL Azure

and here is a useful query that can be run to identify the users and roles that a particular database has. This allows you to check what users are on a database and what are there roles.

SELECT u.name AS UserName, u.type_desc AS UserType, r.name AS RoleName
FROM sys.database_principals AS u
LEFT JOIN sys.database_role_members AS rm ON rm.member_principal_id = u.principal_id
LEFT JOIN sys.database_principals AS r ON r.principal_id = rm.role_principal_id
WHERE
    u.type NOT IN('R', 'G')
ORDER BY
      UserName
    , RoleName;

Note that when deploying or importing data tier applications to for instance SQL Express versions by default contained database authentication is deactivated and must be activated.

To do this connect to the local sql express instance and highlight the Databases on the left hand side then run the following code

sp_configure 'contained database authentication', 1;
GO
RECONFIGURE;
GO

DACPAC (structure only) and BACPAC (data and structure) import should now be possible locally!

This will specifically assist with the following error message which I was getting when I tried to import the database back into a local machine.

TITLE: Microsoft SQL Server Management Studio
------------------------------

Could not deploy package.

MS SQL Azure – Computed Columns

It can be really nice to create a computed column and add it to the table rather than adding it in a field

This would work well using the function listed in the previous post where I automatically calculate the age of trees.

Add Computed Column to SQL Azure Table

ALTER TABLE dbo.t001trees ADD treeage AS (dbo.functionyearmonthday(dbo.t001trees.plantdate, GETDATE()));

This will appear in the table and look like it is an actual field but it is calculated and will not keep the figures in the table unless you specify persistance

see the above link for further reading on this topic

MS SQL Azure – TSQL to name the age between dates in text

It is relatively easy to calculate the number of either years, months days hours or seconds between two dates using the native DATEDIFF built in function which comes with SQL.

e.g.

SELECT dbo.t001trees.pkid, 
dbo.t001trees.plantdate, 
DATEDIFF(Year, dbo.t001trees.plantdate, GETDATE()) as treeage 
from dbo.t001trees;

But here is a function that will spell it out into a string that reads something like
2 days
1 month 2 days
2 years 1 month 2 days

CREATE OR ALTER FUNCTION dbo.functionyearmonthday
(
@datefrom Date,
@dateto Date
)
RETURNS varchar(100)
as
BEGIN
DECLARE @date1 DATETIME, @date2 DATETIME, @result VARCHAR(100);
DECLARE @years INT, @months INT, @days INT;

SET @date1 = @datefrom
SET @date2 = @dateto

SELECT @years = DATEDIFF(yy, @date1, @date2)
IF DATEADD(yy, -@years, @date2) < @date1
SELECT @years = @years-1
SET @date2 = DATEADD(yy, -@years, @date2)

SELECT @months = DATEDIFF(mm, @date1, @date2)
IF DATEADD(mm, -@months, @date2) < @date1
SELECT @months=@months-1
SET @date2= DATEADD(mm, -@months, @date2)

SELECT @days=DATEDIFF(dd, @date1, @date2)
IF DATEADD(dd, -@days, @date2) < @date1
SELECT @days=@days-1
SET @date2= DATEADD(dd, -@days, @date2)

SELECT @result= ISNULL(CAST(NULLIF(@years,0) AS VARCHAR(10)) + ' years ','')
+ ISNULL(' ' + CAST(NULLIF(@months,0) AS VARCHAR(10)) + ' months ','')
+ ISNULL(' ' + CAST(NULLIF(@days,0) AS VARCHAR(10)) + ' days','')

RETURN @result;
END

And if you would like to call the function from another query here is an example

SELECT dbo.functionyearmonthday(dbo.t001trees.plantdate, GETDATE()) as treeage FROM dbo.t001trees

That is enough for most people but it can be expanded to include hours minutes seconds and milliseconds which could be useful if you need more precision it can be seen that the DATEDIFF native function is included extensively within this function.

CREATE OR ALTER FUNCTION dbo.functiontimeperiodmoreprecision
(
@datefrom Date,
@dateto Date
)
RETURNS varchar(100)
as
BEGIN
DECLARE @date1 DATETIME, @date2 DATETIME, @result VARCHAR(100);
DECLARE @years INT, @months INT, @days INT,
@hours INT, @minutes INT, @seconds INT, @milliseconds INT;

SET @date1 = @datefrom
SET @date2 = @dateto

SELECT @years = DATEDIFF(yy, @date1, @date2)
IF DATEADD(yy, -@years, @date2) < @date1
SELECT @years = @years-1
SET @date2 = DATEADD(yy, -@years, @date2)

SELECT @months = DATEDIFF(mm, @date1, @date2)
IF DATEADD(mm, -@months, @date2) < @date1
SELECT @months=@months-1
SET @date2= DATEADD(mm, -@months, @date2)

SELECT @days=DATEDIFF(dd, @date1, @date2)
IF DATEADD(dd, -@days, @date2) < @date1
SELECT @days=@days-1
SET @date2= DATEADD(dd, -@days, @date2)

SELECT @hours=DATEDIFF(hh, @date1, @date2)
IF DATEADD(hh, -@hours, @date2) < @date1
SELECT @hours=@hours-1
SET @date2= DATEADD(hh, -@hours, @date2)

SELECT @minutes=DATEDIFF(mi, @date1, @date2)
IF DATEADD(mi, -@minutes, @date2) < @date1
SELECT @minutes=@minutes-1
SET @date2= DATEADD(mi, -@minutes, @date2)

SELECT @seconds=DATEDIFF(s, @date1, @date2)
IF DATEADD(s, -@seconds, @date2) < @date1
SELECT @seconds=@seconds-1
SET @date2= DATEADD(s, -@seconds, @date2)

SELECT @milliseconds=DATEDIFF(ms, @date1, @date2)

SELECT @result= ISNULL(CAST(NULLIF(@years,0) AS VARCHAR(10)) + ' years,','')
+ ISNULL(' ' + CAST(NULLIF(@months,0) AS VARCHAR(10)) + ' months,','')
+ ISNULL(' ' + CAST(NULLIF(@days,0) AS VARCHAR(10)) + ' days,','')
+ ISNULL(' ' + CAST(NULLIF(@hours,0) AS VARCHAR(10)) + ' hours,','')
+ ISNULL(' ' + CAST(@minutes AS VARCHAR(10)) + ' minutes and','')
+ ISNULL(' ' + CAST(@seconds AS VARCHAR(10))
+ CASE
WHEN @milliseconds > 0
THEN '.' + CAST(@milliseconds AS VARCHAR(10))
ELSE ''
END
+ ' seconds','')

RETURN @result
END

MS SQL Azure – Group child records by parent in order

Lets say we have two tables

A site parent table T001 consisting of two fields
PKID
Sitename

And a planning application child table T002 consisting of three fields
PKID
PKIDT001
PlanRef

We have the following records in the parent table T001
1 – Site01Green
2 – Site02Red
3 – Site03Blue

And the following related children in the planning application table T002;
1 – 1 – 2019/098
1 – 1 – 2018/032
1 – 2 – 2017/987
1 – 3 – 2015/100
1 – 3 – 2014/456
1 – 3 – 2014/657

And we would like to write a query that would create a list combining the two tables showing all the planning applications for each site listed in order.

This is the list we are aiming at
1 – 2018/032,2019/098
2 – 2017/987
3 – 2014/456,2014/657,2015/100

Using SQL Server 2017 or later (including SQL Azure) the following will work

CREATE VIEW [dbo].[View01Sitesandtheirplanapps] AS SELECT PKIDT001, STRING_AGG(PlanRef,',') WITHIN GROUP (ORDER by PlanRef ASC) as PlanRefs
From dbo.T002
GROUP BY PKIDT001;

This can then be combined in a separate view that will include the sitename should it be required – this is a tremendous example the structure of which I will be using often.

SQL SERVER – Create TSQL Trigger to add date to existing record after INSERT or UPDATE

I came across an interesting issue with a web application I have been trying to create. DEFAULTS in SQL Server didn’t seem to be registering when new records were inserted through the web application.

How come? Surely the web application is not bypassing requirements set out by the database.

What I believe is happening is that the web application is explicitly supplying a null value to the dateupdated field and because of this the default value is NOT applied by SQL Server. You are therefore in the strange position of creating a trigger on a column after insert. Normally you would never really do this as that’s specifically what default is for.

Here’s code to create the trigger on the SQL Server that will do just this.

CREATE TRIGGER TR_moddate
On T0001PersonData
AFTER INSERT, UPDATE
AS
BEGIN
UPDATE T0001PersonData SET DATEUPDATED=GETDATE()
WHERE PKID IN (SELECT PKID FROM INSERTED)
END

Some explanation – This updates the field DateUpdated within the table T0001PersonData after an update or an insert. If you have default on a column this may mean that it updates to default then to null then to trigger so you may wish to remove the default on the column. Alternatively you may wish to get the front end to update to the current date. I guess this could have performance issues at scale but my application is pretty small beer so I am happy with this at the moment. I think I prefer to have it at database level as well. It should be noted that INSERTED is actually a ALIAS table created by SQL Server and held in memory that allows for reference to pull out items before they are registered in the database. Leaving out the where clause may have resulted in the application updating the dateupdated column for all records anytime an update or insert was performed. BE WARNED

MS SQL Azure – SQL to Select Distinct list of Child Records based on a Maximum or Minimum Child Field Value

Following on from the previous post I wanted to know the syntax for SQL to do the same but in SQL Azure.

SELECT * FROM dbo.T02AttendanceGame T1    
WHERE Attendance = (
   SELECT max(Attendance)
   FROM dbo.T02AttendanceGame T2
   WHERE T1.FKID=T2.FKID
);

I created the same tables that I created for the MS Access example with the same field names but within a SQL Azure database.

Here’s the same SQL but then creating a view called rather unimaginatively ‘View01’

CREATE VIEW VIEW01 AS SELECT * FROM dbo.T02AttendanceGame T1    
WHERE Attendance = (
   SELECT max(Attendance)
   FROM dbo.T02AttendanceGame T2
   WHERE T1.FKID=T2.FKID
);

MS SQL Azure – Take Complete Backup of Azure Database (Structure and Data)

SQL Azure as part of the service offers a number of differing back up options as standard – however you may wish to take additional backups which for instance you can load onto a local version of SQL Server (Express or Enterprise). Here’s a quick rundown of one method of doing this.

Firstly open up your version of SQL Server Management Studio and navigate to the instance and database that you wish to backup

Highlight the database in this case DB001 and right click -Select Tasks and Export Data-Tier Application

Choose an appropriate location to put the backup file

Review the summary of items that will be backed up and then hit Finish

There will be a run down of how the export has worked

And just a check to see the exported file in the directory
