Home -> Community -> Mailing Lists -> Oracle-L -> slow insert
hi,
I have an insert statement that will insert about 400000 records into a table having 43million records.The values for the insert statement are from a select statement that has a join.This query take about 5-10minutes.What are the ways in which we can speed up this process.the statement looks like
insert into .......
select ....... from a,b
where a.col1=b.col1 --->index columns
and a.col2=x -->non index
and b.col2=x -->non index
Thanks
