Using CHAR in UDF causes SQL0204

This one is weird. Actually, it begins to make a little sense.

Anyway, according to an article <http://www-1.ibm.com/servers/eserver/iseries/db2/udfnotfnd.htm> "UDF - Function not found", if you pass a constant to a function declared with CHAR, it'll fail with this error. Reason is, constants are handled as VARCHAR, not CHAR.

I assume that if you used an explicitly CHAR variable, or cast the constant as CHAR, it might work.

One interesting thing is, the value passed does not contain the length information that VARCHAR has, so it's pretty easy to process. I used CL with PARAMETER STYLE SQL - found GENERAL too complicated for the time I had

HTH someone.
