DB2 Function LISTAGG failing with SQL0440N

We have several DB2 Servers and multiple instances all running DB2 LUW (windows) DB2  V9.7 Fixpack 9

a call to DB2 Function LISTAGG is working against some of the databases - and failing in others.

Here is the SQL:  

SELECT COL1, COL2, LISTAGG(AGT_DESGNT_CD,',') WITHIN GROUP (ORDER BY AGT_DESGNT_CD ) AS AGT_DESGN_DESC
 FROM myschema. mytable
GROUP BY COL1, COL2
ORDER BY COL1, COL2

Here is the error:
Error during Prepare
 42884(-440)[IBM][CLI Driver][DB2/NT] SQL0440N  No authorized routine named "LISTAGG" of type "FUNCTION" having compatible arguments was found.  SQLSTATE=42884

I cannot find a pattern as to why it is failing in some databases and not in others.   On one Server, I have 2 Databases - both in the same instance - and it is failing in one and not the other.

Hi me,

Functions in DB2 look a lot like functions in object oriented languages in that the same function name can be used over and over.

SQL0440N  No authorized routine named "LISTAGG" of type "FUNCTION" having compatible arguments was found.  SQLSTATE=42884

The error that you're seeing indicates that there is no definition of LISTAGG that has a matching parameter type list.  That is, it may exist with parameters (varchar, varchar), but not (int, varchar).


Check the version of DB2 on all of the servers.  It may be that DB2 on the server that's giving you trouble is older than the others and LISTAGG isn't in the system library.

Check the system library (sysibm) and make sure that LISTAGG is defined there.

LISTAGG is recursive.  It could be that the result is longer than the default limit of 4000 characters.  (Though I would expect a different error.)  Try recasting the source name.  DB2 recursive SQL propogates the source length through the entire query.

  LISTAGG(CAST(AGT_DESGNT_CD AS VARCHAR(10000)), ',')


Good Luck,
Kent
