Also, you cannot have the multiple Global Temporary tables with the same name.
Or a little shorter:
If Object_ID('tempdb..##table
Create Table ##table_name (col1 int)
If Object_ID('tempdb..##table
Create Table ##table_name (col1 int)

kselvia - in 'tempdb..##table_name' what are those 2 dots about?
Or, a little more portable:
If Not Exists(Select * From TempDB.Information_Schema.
Create Table ##table_name(Col1.Int)
This is guaranteed to work in future versions as well.

I think Sjoerd was refering to Ram2098's answer rathe than mine. Yes, if you need to reference sysobjects, it is better to reference information_schema tables. Sysobjects may not be supported in the future.
