RE: UDTF (or similar) to retrieve data from SYSPARTITIONSTAT



fixed

This all worked for me (tweak where it makes sense):

drop function needles.libstats;

CREATE FUNCTION needles.LIBSTATS ( SCHEMA_NAME VARCHAR(10) ) RETURNS TABLE (
Lib_Schema CHAR(10)
, Table_Name CHAR(10)
, Mbr_Name CHAR(10)
, Owner CHAR(10)
, Text CHAR(50)
, Days_Used INTEGER
, Nbr_Rows BIGINT
, Del_Rows BIGINT
, Del_Percnt DECIMAL( 5 , 2 )
, Data_Size BIGINT
, Last_Used CHAR(10),
-- Created CHAR(10)
Last_Chgd CHAR(10)
, Last_Saved CHAR(10)
, Last_Rstrd CHAR(10)
)

LANGUAGE SQL
DETERMINISTIC
NOT FENCED
NO EXTERNAL ACTION
DISALLOW PARALLEL
CARDINALITY 10

BEGIN

RETURN

SELECT

WHEN ( Card = 0 ) AND ( Deleted > 0 ) THEN 100.00

END
AS DECIMAL( 5 , 2 )
) AS PercntDltd

FROM qsys2.syspartitionstat
WHERE Sys_DName = UPPER( SCHEMA_NAME )
ORDER BY Sys_DName, Sys_TName, Sys_MName

END;


SELECT MYLIB.* FROM TABLE(needles.LIBSTATS('qgpl')) AS MYLIB;

Not stupid and yes, the library does exist. If I isolate the SELECT statement and substitute a literal library name for SCHEMA_NAME in the WHERE clause, it returns rows successfully. In fact, I've tried it with many library names with the same results.

It MUST be in the function statement itself but I have no idea where.

This might sound stupid...but have you checked to make sure the library you are testing with exists in the tables?
