Cursor Error -504 with 'FOR UPDATE OF' clause

Hi,

Will the 'FOR UPDATE OF' clause work when the Cusror declared has the join of more than one than one table? Because i'am gettin a -504 (Cursor Name is Not defined) when i'am trying to bind the application program .I've checked the program and the Cursor is declared.

I've declared a Cursor as

EXEC SQL
DECLARE CSR1 CURSOR FOR
SELECT A.Column2,A.Column3,B.column4
FROM Table1 A,
Table2 B
Where A.Column1=B.column1
For Update of Column2,Column3
END-EXEC

and my update clause is

EXEC SQL
UPDATE Table1
SET Column2 = 'ABCD'
, Column3 = '12345'
WHERE CURRENT OF CSR1
END-EXEC.

Thanks in advance

As for as I know FOR UPDATE clause cannot be used in the following scenarios.

1) If the cursor associated with the SELECT statement cannot be deleted.

2) If at least one of the selected columns is a column that cannot be updated in a catalog table and has not been excluded in the FOR UPDATE clause.

Just check whether the above cases are existing in your cursor.
