There is already an object named '##Temp' in the database

Question

I have a stored procedure on SQL Server 2000. It contains:
select ... into ##Temp ...
...
drop table ##Temp

When I run the stored procedure

Answer 1

Since you chose to use a global temporary table ##Temp, it is visible to all SQL connections at any given time. Obviously, while the stored proc is running for one connection, a second connection comes in and tries to create yet another ##Temp but that already exists....

Use connection-local #Temp tables (only one #) instead.
