PRB: ODBC Error When Updating an Edited Record

• Microsoft Visual Database Tools, version 1.0

SYMPTOMS

The following error occurs in the Query Designer when you move off an edited table record:

ODBC Error: Client Cursor: 12 - No key columns are specified for the update table.

CAUSE

In the Query designer, a table must have a key column specified so that you can edit the table data. The Query Designer uses SQL "Update ... Where" syntax to update the record and requires a key field in the Where clause to uniquely identify the record.

RESOLUTION

Specify a key column in your table. See the InfoView topic titled [ASCII 147]Defining a Primary Key[ASCII 148] under [ASCII 147]Microsoft Visual Database Tools, Database Designer, Working with Database Objects, Constraints[ASCII 148]

STATUS

This behavior is by design.

5. Move off the record you just added.

7. Move off the record. The error message described above appears.
