ID: Q166882


The information in this article applies to:


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.


MORE INFORMATION

Steps to Reproduce Behavior

  1. Create a new table.


  2. Save the table.


  3. Open the table.


  4. Add a new record to the table.


  5. Move off the record you just added.


  6. Go back and edit a field in the new record.


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