RE: Specify null parameter for SQL UDF

["Elvis Budimlic" <ebudimlic@xxxxxxxxxxxxxxxxxxxxxxxxx>]

I always use DB2SQL so it better exist :)

Here are some links I've used in the past:

* COUNTER() returns a unique row identifier for each row in the result set;
I use it often in our shop.

Slight variation of COUNTER():

* DB2SQL parameter style details.

* RPG example with DB2SQL and SCRATCHPAD

Hi Elvis,

I was considering using PARAMETER STYLE DB2GENERAL, but the SQL 
Reference manual says "DB2GENERAL is only allowed when the LANGUAGE is 
JAVA."  It also says "SCRATCHPAD is only allowed with PARAMETER STYLE 
DB2SQL or PARAMETER STYLE DB2GENERAL." but there is no PARAMETER STYLE 
DB2SQL, just PARAMETER STYLE SQL.

When I get some time I'll try PARAMETER STYLE SQL and ignore the 
SQL-related parameters.
