BUG #: 18555 (SQLBUG_65)
A dynamic cursor on a table without a unique index re-fetches the current row after a positioned update that uses the Transact-SQL UPDATE WHERE CURRENT OF <cursor> syntax.
To work around this behavior:
Avoid using a dynamic cursor.
Create a unique index for the table on which the cursor is based.
