I've the need to create a TempTable in SQL server, if that TempTable doesn't exist yet.

I can create it with:
SQLEXEC(lnActiveConnection,"create table #TempQuery ID char(36) PRIMARY KEY)")

but I can't verify its existence neither with:
SQLEXEC(lnActiveConnection,"EXEC sp_tables @table_name = '#TempQuery';")
(the statement return 0 records) nor with:
SQLEXEC(lnActiveConnection,"EXEC sp_tables @table_name = '#TempQuery', @table_owner = 'dbo', @table_qualifier = 'tempdb';")
(this statement return -1).

How to get the information?
TIA
