ACC: How to Delete Multiple Tables Quickly (2.0, 95, 97)

• Microsoft Access version 2.0, 7.0, 97

SUMMARY

Moderate: Requires basic macro, coding, and interoperability skills.

In some situations, you may want to delete multiple tables quickly, rather than deleting them one at a time. For example, when you import data from another product, an error table may be created. After many imports, there may be several error tables to delete.

This article describes how to delete multiple tables quickly using data access objects (DAO).

This article assumes that you are familiar with Visual Basic for Applications and with creating Microsoft Access applications using the programming tools provided with Microsoft Access. For more information about Visual Basic for Applications, please refer to your version of the "Building Applications with Microsoft Access" manual.

NOTE: Visual Basic for Applications is called Access Basic in Microsoft Access version 2.0. For more information about Access Basic, please refer to the "Building Applications" manual.

MORE INFORMATION

The following example demonstrates how to use DAO in code to loop through the TableDefs collection and delete any tables whose name begins with "Import Errors."

1. Create a module and type the following line in the Declarations section if it is not already there:

         Option Explicit
   

2. Type the following procedure:

         Function DeleteImportErrorTables ()
            Dim db As Database, t As TableDef, i As Integer
            Set db = CurrentDB()
            For i = db.tabledefs.count - 1 To 0 Step -1
               Set t = db.tabledefs(i)
               If t.name Like "Import Errors*" Then
                  db.tabledefs.Delete t.name
               End If
            Next i
            db.Close
         End Function
   
   

3. To test this function, type the following line in the Debug window (or the Immediate window in version 2.0), and then press ENTER.

         ? DeleteImportErrorTables ()
   

   Any table whose name begins with "Import Errors" is deleted without confirmation.
