    Tables Comparison

    I am looking for a VB6 Add-in/ActiveX/Application that will allow me compare two tables and modify the second based on the first. Tables are the same name, just different databases. Functions like compare, delete fields, add fields, update fields. I will really appreciate anybody's input. Meanwhile I will create my own and post it later, but would like to know if anyone has done such thing in the past.

    Thanx
    Stan

    Re: Tables Comparison

    You can create 2 recordsets and compare them

    Dim dbcurrent As Database
    Dim qryMyQuery As QueryDef
    Dim recMatching as Recordset
    ' Set the database
    Set dbcurrent = OpenDatabase("c:\my files\myData.mdb")

    'Create a Query
    Set qryMyQuery = dbcurrent.CreateQueryDef(MyQuery, "SELECT * FROM [Tablename] WHERE [Exclusions]")

    Your next move is to create a recordset based upon the matching criteria......

    Set recMatching = dbcurrent.OpenRecordset("SELECT * FROM [Table2] INNER JOIN [MyQuery] ON [Table2].[common
    field] = [MyQuery].[Common Field]")


    The recordset will now contain all the matching criteria that you will be able to manipulate in whatever
    form you like.
