Hi
When I look for the entries related to my program in DSN_STATEMNT_TABLE, I could see that one of my query has high PROCMS value. High can I trace which query is yielding this? I've many queries in the program on the same table.

Please advice.

There is a statement number associated with the row,
this statement number refers to your db2 precompiler output.

alternatively,
you can go to the dbrm for your module
and search for the statement number (it is in binary)

this link is a REXX ISPF Macro that I wrote that will find the sql in your dbrm.

via dsn_query_table & XML
Code:
select
a."QUERYNO", a."COLLID", a.PROGNAME, a.EXPLAIN_TIME
,cast(xml2clob(xmlquery('$c/QUERY//text()' passing xmlparse(q.node_data) as "c")) as varchar(10000))
from
DSN_STATEMNT_TABLE A
, DSN_QUERY_TABLE Q
where a."COLLID" = ,
and a.EXPLAIN_TIME = q.EXPLAIN_TIME
and a."QUERYNO" = q."QUERYNO"
and q.QUERY_STAGE = 'BEFORE'
and q."TYPE" = 'SELECT'


the other way is via syspackstmt;
stmt is in "for bit data , but most of it is readable unicode"
Code:
select
a."QUERYNO", a."COLLID", a.PROGNAME, a.EXPLAIN_TIME
,p.version
,i.stmt
from DSN_STATEMNT_TABLE A
   , plan_table P
   , sysibm.syspackstmt I
where a."COLLID" = ?
and a."COLLID" = p."COLLID"
and a.PROGNAME = p.PROGNAME
and a.EXPLAIN_TIME = p.BIND_TIME
and I.LOCATION = ''
and i."COLLID" = p."COLLID"
and i.NAME = p.PROGNAME
and i."QUERYNO" = p."QUERYNO"
