MS Access VBA Functions (Part 1) Address Matching – Add and Drop Fields

Here are a series of Functions that can be used to help in matching addresses between a dataset that is good (eg Assessors Street File) and a dataset that could be improved – eg a Customer Relationship Management System.

ADD and DROP Fields

Function AddCharColumn(TblName As String, FieldName As String)

DoCmd.RunSQL "AlTER TABLE [" & TblName & "] ADD COLUMN " & FieldName & " CHAR(100);"

End Function

Function AddIntegerColumn(TblName As String, FieldName As String)

DoCmd.RunSQL "AlTER TABLE [" & TblName & "] ADD COLUMN " & FieldName & " INTEGER;"

End Function

Function AddDoubleColumn(TblName As String, FieldName As String)

DoCmd.RunSQL "AlTER TABLE [" & TblName & "] ADD COLUMN " & FieldName & " Double;"

End Function

Function DropColumn(TblName As String, FieldName As String) As Variant

DoCmd.RunSQL "ALTER TABLE [" & TblName & "] DROP COLUMN " & FieldName & ";"

End Function
