The information in this article applies to:
  • Microsoft SQL Server, version 6.5
BUG #: 17803 (6.5)

SYMPTOMS

If you precede a column name with the table alias in the FOR UPDATE clause of a cursor, cursor declaration will fail with the following error:

   The column name 'au_lname' specified in the FOR UPDATE list is invalid
   or ambiguous.
The following example statements will demonstrate the problem: 

   declare t1_cursor cursor for
   select au_id, au_lname
   from authors a1
   for update of a1.au_lname

WORKAROUND

To work around this problem, either remove the alias or prefix the column name with the table name.
