| I have a table which contains approx 3,00,000 records. I need to import this data into another table by executing a stored procedure. This stored procedure accepts the values from the table as params. My current solution is reading the table in cursor and executing the stored procedure. This takes tooooooo long. approx 5-6 hrs. I need to make it better. Can anyone help ? Samir |

| Cursors are evil!!!! However, to be able to fully answer your question, we need to see your stored proc/schema or even the results of a showplan. I have used DTS/stored procs to import all sorts of data and have never once had to resort to cursors (maybe I have just been lucky). Generally speaking, I normally just do a select statement from the source table which is used as input to the destination and doing any casting/coercion along the way. eg create proc finky as insert into source (a ,b ,c ) select a as char(2) ,IsNull(b, '') ,c from destination samirpandey@hotmail.com (Samir Pandey) wrote in message news:<33d418fa.0308071922.5061c0a4@posting.google. com>... > I have a table which contains approx 3,00,000 records.

| Hey thanks for your help. but....i just can't simply insert data in the destination table. I need to run the values thru a logic which exists in stored procedure.(e.g. if existing price is less than the new price, then update another field which means that the price has reduced/increased on a particular day)... and some other i make in the stored procedure. Thats why i need to run the values thru a stored procedure. now can you help...? thanks alot....
