I have a table that every 30 minutes needs to be repopulated from
another table that is recreated from scratch just before.
What I did was this:
CREATE PROCEDURE BatchUpdProducts AS
begin transaction
delete products
insert into products
select * from productsTemp
commit transaction
GO
This takes about 30 seconds to run. I tried it doing it with a cursor,
row by row, but it took like 30 minutes to run instead. The problem
is with the fast approach is, once in a while I get a deadlock error
in different areas trying to access the products table. Using SQL
Server 2000 by the way.
Any ideas?
