TimesTen Error Messages

TT-02785

Column column_name has no unique constraint


Cause

You attempted to issue an ALTER TABLE statement to drop a UNIQUE constraint, but there was no UNIQUE constraint defined for the column.


Action

Check the constraints defined on the columns of the table, making sure the column you want to drop has a unique constraint defined on it. Run the ttIsql indexes command on the table to display the constraint information. For more information, see ALTER TABLE in Oracle TimesTen In-Memory Database SQL Reference or ttIsql in the Oracle TimesTen In-Memory Database Reference.


Additional Information

TimesTen did not alter the table to drop the constraint.
