FIX: Invalid Argument Err on Execute Method w/ SQL Passthrough

• Microsoft Visual Basic Professional Edition for Windows, version 3.0

SYMPTOMS

When you open a database using ODBC and use the Execute method of the Database object or property with the SQL passthrough option (value 64) specified, the error "Invalid argument" (number 3001) incorrectly occurs.

WORKAROUND

Here are two possible workarounds. Use either one.

• Use the ExecuteSQL. Its default is DB_SQLPASSTHROUGH:

  
        i = db.ExecuteSQL("action statement") 




• Use CreateDynaset or CreateSnapshot with the SQL passthrough option to execute an SQL action statement. Then close the resulting recordset object immediately. Here's an example:

  
        Dim ds As Dynaset
        Set ds = db.CreateDynaset("action statement", SQL_PASSTHROUGH)
        ds.Close 

  If you are using the data control, specify datacontrol.Database as the database variable as in this example:

  
        ' Enter the following two lines as one, single line:
        Set ds = Data1.Database.CreateDynaset("action statement",
           SQL_PASSTHROUGH) 

STATUS

Microsoft has confirmed this to be a bug in the products listed above. This problem was fixed in the Compatibility Layer (COMLYR.EXE) update.
