Deleting records

    We find that SQL is taking a lot of time to delete (selective) records. Is there any effective way of deleting records in a table??

    How is your table structured? What indexes do you have on the table? What is the statement your are using to delete the record?

    If you have a single field clustered index and use that field as the selection criteria for your query, then the delete will be relatively quick. However, if you have a composite index, using that as you criteria will prove to be slower. The datatypes and ordering of the fields in the index can make a difference also.

    Hope this helps

    Thanks. I will check the indexes and the order of the fields.
