We just completed a massive 39 database conversion to SQL Server for a client in Tennessee which was quite challenging, we had to not only upsize all the tables, but switch the system from importing/exporting between databases to using linked tables instead. At times we needed to find which queries was using a table, so we used the following code to quickly find a table in all of the queries:
Public Function SearchQueries(strTableName As String)
   Dim qdf As DAO.QueryDef
   Dim strSQL As String
   On Error GoTo ErrorHandler
   For Each qdf In CurrentDb.QueryDefs
       Application.Echo True, qdf.Name
       strSQL = qdf.SQL
       If InStr(1, strSQL, strTableName) > 0 Then
           Debug.Print qdf.Name
       End If
   Next qdf
   Set qdf = Nothing
   MsgBox "Search Completed"
   Exit Function
   If Err.Number = 3258 Then
       strSQL = ""
   End If
End Function

Let’s say we need to find where tblCustomers is being used in the query collection, we would press Ctrl-G to go to the Immediate window and type:
The system will return all the queries where used in the same immediate window:
