SQL Server insert performance

Question

I have an insert query that gets generated like this

INSERT INTO InvoiceDetail (LegacyId,InvoiceId,DetailTypeId,Fee,FeeTax,Investigatorid,SalespersonId,Creat         


        

Answer 1

Sounds like the inserts are causing SQL Server to recalculate the indexes. One possible solution would be to drop the index, perform the insert, and re-add the index. With your attempted solution, even if you tell it to ignore constraints, it will still need to keep the index updated.
