SYMPTOMS

When entering SQL statements in Visual Basic 5.0 Visual Data Manager (VisData), the record count may be incorrect. The same SQL statement entered in Visual Basic 4.0 Data Manager will return the correct number of records.

CAUSE

All records do appear in some circumstances, such as with the DBGrid control, Data Manager, etc., because in these circumstances all records need to be retrieved to be displayed to the user, in which case there is no need to explicitly call MoveLast.

RESOLUTION

Always go the last record in VisData or issue a MoveLast of a recordset variable in order to get the correct record count using the DBGrid.

STATUS

This behavior is by design.

MORE INFORMATION

Steps to Reproduce Behavior

Within VisData:

Open Nwind.mdb.

Enter the following SQL statement:

     select * from customers where customers.customerid like "*"

Execute the statement and note that VisData will report two records being returned.

In Visual Basic 4.0 Data Manager:

Open Nwind.mdb.
Enter the same SQL Statement and note that Data Manager returns 91 records.
