Oracle Query Tuning

edited Aug 28, 2009 5:39AM in Database Tuning (MOSC) 8 commentsAnswered
Hello,

         I am trying to write a query that joins multiples tables with in a database and then joins to one more table from a different database using a database link. I think I have the query written but execution time for the query appears to be in excess of 2 hours. I need to find a way to speed the query up. I'd appreciate any thoughts anyone might have on this.

Query:

INSERT INTO inddmd.tidemark_weekly_extract
    (SELECT a.csm_caseno permit_no, a.case_type permit_type,
            a.csm_status permit_status, a.csm_issued_date permit_issued_date,

Howdy, Stranger!
