AS400 - 令牌“！” 无效

Question

I'm running a SQL query using RUNSQL into a CL program. This query is a basic SELECT statement and uses the exclamation mark to concatenate strings.

For years until yesterday, it worked fine. Now, out of nowhere, I've got a SQL0104 message displaying Token '!' not valid every time I run the program.

If I run the query manually using STRSQL, it works.

Did this occur to someone?

Best regards.

Answer 1

DB2's operator for string concatenation is actually the double pipe || .

The documentation says :

Use the concatenation operator ( || ) to join two values of an expression into a single string. In some non-English, single-byte character sets, the || can display as !! (exclamation marks) or other special characters.

So your issue may be caused by a change in the character set of your client. Just use the standard operator, and your code will work regardless.
