| I have looked at several examples but can not get any of them to work in SQL 2005. I have a Perl Script that is parsing through a flat file loading each row into a database as a record. I am creating a key on the fly by combining some fields from the flat file.In Perl basically I build the SQL string and simply call the SQL module to do the insert for with the complete SQL string.My insert stringINSERT INTO fueltemp(tkey,date,time,scan,duration,durday,durhour,durmin,dursec,location) values ('$tkey','$ndate','$time','$scan','$duration','$durday','$durhour','$durmin','$dursec','$location')";what do I need to add to this string to check and see if the key $tkey does not already exist in fueltemp?Thanks,BatCat.Regards,The Dark Knight-Give What is Right, Not What is Left- |

Create a proc that checks for the value before inserting and call the proc for each row..Or dump the rows into a staging table and call a proc that will batch insert only unique rows into the main table.IF NOT EXISTS (SELECT * FROM YourTable WHERE tKey = @Tkey) INSERT INTO....

| Thanks - it still gave an error the first time becasue my key contains non alpha characters. But one I put the $tkey in single quotes it went like it should.Regards,The Dark Knight-Give What is Right, Not What is Left- |
