SQL0501N The cursor specified in a FETCH statement or CLOSE statement is not open or a cursor variable in a cursor scalar function reference is not open. SQLSTATE=24501

From here :

Explanation

The program attempted to do one of:

    FETCH using a cursor at a time when the specified cursor was not open.
    CLOSE a cursor at a time when the specified cursor was not open.
    Reference a cursor variable in an OPEN statement and the cursor variable is not open.
    Reference a cursor scalar function, such as CURSOR_ROWCOUNT function, and the cursor variable is not open.

The statement cannot be processed.


User response

Check for a previous message (SQLCODE) that may have closed the cursor. Note that after the cursor is closed, any fetches or close cursor statements receive SQLCODE -501.

If no previous SQLCODEs have been issued, correct the application program to ensure that the cursor is open when the FETCH or CLOSE statement is executed.

If a cursor variable is referenced in a cursor scalar function, verify that that the cursor is not null, is defined, and is open, else replace the cursor variable with one that is in that state.

i could see this help from db2 ? SQL0501N

Can you pls elaborate more?

i am attaching the file with code.

Can you please guide me more.

Thanks a lot for your help

No code attachment.

Usually this just means that you tried to FETCH or CLOSE a cursor that isn't open.  Usually this is due to a defect in your code.  Maybe the OPEN failed and you didn't detect it, for example.

Yes, i have changed my for cursor statements to while cursor and error is not throwing now.

but i need to know how to use the data studio to trace the particular order value (i mean for a particular data value) for step by step
