  I have a insert query in stored procedure it takes min 59 or 110 specs to insert into table.
  query is
  insert into tab1
  select distinct col1,col2,.....
  if I change select  distinct to top keyword it executes in secs....
  How to  improve performance of this query....

  Well how fast does the just the select run without the insert?

  And how many rows does the distinct return vs. how many rows you were returning with the TOP X

  In this case, the SELECT part of the query takes too long. Please post the actual execution plan of the SELECT part as a .sql file attachment. Thanks.

  well if itry to insert 4 lakh row with top key work it executes fast but with distinct to insert even 1 lakh rows it takes 59 secs

  You need to do what Chris is suggesting, get the execution plan. We can speculate all day why one query runs faster than another (although DISTINCT is an aggregation function and notorious for causing performance issues when it's used inappropriately, so there's that) but without evidence, all we're doing is guessing.

  This is the v2012 section of a SQL Server forum. Have you tried posting in a Sybase forum? You might get lucky here but it's a long shot.

  Sorry, I don't know Sybase.

  This forum is for Microsoft SQL Server. You might be better off tracking down a forum for Sybase.
