[SQL] Query tuning

2008-05-14 Thread kapil.munish
Hi,





I have a query which is run across 3 tables JOB_TYPE_FIRST,
JOB_TYPE_SECOND and JOB_ALLOCATION_WORKLIST.



The column JOBID is referenced in JOB_ALLOCATION_WORKLIST table and
primary key in both JOB_TYPE_FIRST, JOB_TYPE_SECOND tables.



There is one more column BOOK_ID which is supplied as the binding
parameter to the query. The query looks like:



select count(distinct(j.JOBID)) as jobCount

from  JOB_TYPE_FIRST a, JOB_TYPE_SECOND b, JOB_ALLOCATION_WORKLIST j

where (( a.JOBID = j.JOBID)

and (a.BOOK_ID = :bookId))

or ((b.JOBID = j.JOBID)

and (b.BOOK_ID = :bookId));



As the records in the database are too large it is having huge cost and
stalling the server and takes lot of time.



Can anyone suggest a better way to fetch the results for the query or
tune it? Any help would be highly appreciated.





Thanks & Regards,

Kapil

Hi Venkat,





What kind of relation you want to create? Is it to do with the creation
of dependencies or something else?
