select query performance

As it depends on a lot of factors, it would be nice to know, how many records are in each of these tables and which indexes there are. Furthermore, could you please post an explain-plan? That would make it much easier.

Each tables have 5000 to 10000 records.
indexes are:
table: XBrlTickerDetail: Index:ROLE, PERIOD, ELEMENTID, TICKER
table:XBrlTmpXsdDet: Index:PERIOD, ELEMENTID, TICKER
table:XBrlTickerLab: Index: TICKER, LABELID, PERIOD
table:XBRLTICKERPRE: Index:PERIOD, ELEMENTID, ROLE, TICKER
Explain Plan:

I'm afraid, the explain plan is missing in your last post.

Which table do startdate and enddate belong to?
I would use  XBrlTickerDetail as the driving table (so it should be the last table in the from-clause), although the optimizer probably does use it this way anyway (as long as the table statistics have been gathered not too long ago).

startdate and enddate belongs to table XBrlTickerDetail.
give proper solution for this problem.
i am not able to send explain plan.

Hi,

You might try this one (it''s a bit hard if I don't know the current approach of the database):

SELECT a.elementid, D.ELEMENTORDER, LabelText AS ElementLabel,
       Amount as Amount0, 0 as Amount1, 0 as Amount2,
       0 as Amount3, 0 as Amount4, 0 as Amount5
  FROM XBrlTmpXsdDet  B, XBrlTickerLab  C, XBRLTICKERPRE  D,
       XBrlTickerDetail  A
 WHERE B.ticker = A.ticker
   AND B.period = A.period
   AND B.elementid = A.labelid
   AND C.period = A.period
   AND C.labelid = A.elementPropertyName
   AND C.ticker = A.ticker
   AND D.ticker = A.ticker
   AND D.role = A.role
   AND D.elementid = A.elementid
   AND D.period = A.period
   AND trunc(a.startdate) = to_date('12/31/2006', 'MM/DD/YYYY')
   AND trunc(a.enddate) = to_date('12/31/2006', 'MM/DD/YYYY')
   AND A.ticker = 'edgr'
   AND A.period = '20071231'
   AND A.role = 
       'http://xbrl.us/us-gaap/role/statement/StatementOfShareholdersEquityAndOtherComprehensiveIncome'
