Dynamically Change the Access Passthrough Query Definition

Dynamically Change the Access Passthrough Query Definition

This is a useful tip if you are using SQL Server as your database and Accessas your front-end application. Use the following code to dynamically change theAccess passthrough query definition, which helps topull necessary data from the server while avoiding redundantnetwork traffic.

 Private Sub ChangeQueryDefinition()   Dim dbs as Database   Dim strSQL as String   Dim strQuery as String   Dim strPassthroughQuery as String   Dim qDef as QueryDefinition   Set dbs=Currentdb()   strQuery="Your Access query name"   srrPassthroughQuery="Your SQL Server view name"   '*** Build your SQL statement ***   strSQL="SELECT * FROM " & strPassthroughQuery            & " WHERE condition"   Set qDef=dbs.Querydefs(strQuery)   qDef.Sql=strSQL   Set qDef=Nothing   Set dbs=NothingEnd Sub

The resulting passthrough query can be used to connect to any list box or combo box.
