Looking at the Data Dictionary in MS Access

Date: Mon, 7 Feb 2005 12:36:06 +1100
From: Gerry Patterson

It is still difficult to discover any documentation about the MS Access
Data Dictionary. A while ago, I needed to drop tables in an SQL script.
However, I needed to know whether or not they existed, before I tried
dropping them. Otherwise a fatal error condition would occur whenever a
script tried to drop a non-existent table.

The following was my solution to this problem:

=========================================================================

Public Function ZapTable(TabName As String) As Boolean
' Zap a table -- but check first that it exists
' This is a useful subroutine for cleaning up dynamically created tables
Dim dbs As Database
Dim rst As DAO.Recordset
Dim sql As String

    On Error Resume Next
    Set dbs = CurrentDb
    sql = "SELECT * FROM MSysObjects WHERE (MSysObjects.Type = 1) AND (MSysObjects.Flags = 0);"
    Set rst = dbs.OpenRecordset(sql, dbOpenDynaset)
    rst.FindFirst "UCase(Name) = '" & UCase(TabName) & "'"
    If rst.NoMatch Then
        zap_table = False
    Else
        DoCmd.RunSQL "DROP TABLE " & TabName & ";"
        zap_table = True
    End If
    rst.Close

End Function

=========================================================================

To date, I have not been able to find a table that describes columns in
an MS Access database.
