Implicit type conversion in DB/2 inserts?

We're using SQL Ins开发者_运维百科erts to insert some data via a script into DB/2 tables, e.g.

CREATE TABLE TICKETS (TICKETID VARCHAR(10) NOT NULL);

On my home installation, this statement works fine (note that I'm using an integer which is autoatically cast into a VarChar):

INSERT INTO TICKETS (TICKETID) VALUES (1);

while at my customer's site I get a type error.

My question(s):

• Is this behavior version dependent? (I use a DB2 Express V9.7, while the customer has an Enterprise V9.5)
• Is there a config option to change the behavior? (I would like my home install to behave as close as possible as the production environment is going to be.)

DB2 9.5 and earlier enforced strong typing.

DB2 9.7 relaxed this requirement, adding implicit casting between data types. See the documentation: What's new in DB2 V9.7: Implicit casting
