IBM Data and AI Ideas Portal for Customers


Shape the future of IBM!

We invite you to shape the future of IBM, including product roadmaps, by submitting ideas that matter to you the most. Here's how it works:

Post your ideas

Post ideas and requests to enhance a product or service. Take a look at ideas others have posted and upvote them if they matter to you,

  1. Post an idea

  2. Upvote ideas that matter most to you

  3. Get feedback from the IBM team to refine your idea

Help IBM prioritize your ideas and requests

The IBM team may need your help to refine the ideas so they may ask for more information or feedback. The product management team will then decide if they can begin working on your idea. If they can start during the next development cycle, they will put the idea on the priority list. Each team at IBM works on a different schedule, where some ideas can be implemented right away, others may be placed on a different schedule.

Receive notification on the decision

Some ideas can be implemented at IBM, while others may not fit within the development plans for the product. In either case, the team will let you know as soon as possible. In some cases, we may be able to find alternatives for ideas which cannot be implemented in a reasonable time.

SQLCODE SQL0302N should give hint which parameter is too long.

Scenario: prepared statements
Error: host variable too long
Problem: SQL0302N should give a hint which parameter is affected.

Details:
Using prepared statements with parameter markers such as
INSERT INTO TESTTAB (COL1, COL2) VALUES (?, ?)");
DB2 throws SQN0302N if a value of a host variable does not fit into the DB2 column. SQL0302N on LUW does not give a hint which column is affected (which host variable was too long). SQL0302N on z/OS does.

Example:

PreparedStatement pstmt1 = con.prepareStatement("INSERT INTO TESTTAB (COL1, COL2) VALUES (?, ?)");
pstmt1.setInt(1, 91);
pstmt1.setString(2, "TooLongggggggggggggggggg");

SQL0302N The value of a host variable in the EXECUTE or OPEN statement is out of range for its corresponding use. SQLSTATE=22001

For statements not using parameter markers DB2 throws SQL0433N which is easier to debug:
INSERT INTO TESTTAB (COL1, COL2) VALUES (91, 'TooLongggggggggggggggggg')
SQL0433N Value "TooLongggggggggggggggggg" is too long. SQLSTATE=22001
