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

Some suggestions for increasing insert performance:

• Increase ADO.NET BatchSize
• Choose the target table's clustered index wisely, so that inserts won't lead to clustered index node splits (e.g. autoinc column)
• Insert into a temporary heap table first, then issue one big "insert-by-select" statement to push all that staging table data into the actual target table
• Apply SqlBulkCopy
• Place a table lock before inserting (if your business scenario allows for it)
