if exists (select * from sys.tables where name = N'##Temp02')
drop table ##temp02;    

This T-SQL is not working.  The table ##temp02 is not being dropped?

You should check in tempdb

if exists (select * from tempdb.sys.tables where name = N'##Temp02')
drop table ##temp02;

This will do..

IF EXISTS (SELECT * FROM tempdb.dbo.sysobjects WHERE ID = OBJECT_ID(N'tempdb..##Temp02'))
DROP TABLE ##temp02;

Local temporary tables are destroyed when you close your connection to SQL Server. There is no need to manually purge them under normal circumstances. If you maintain a persistent connection, or connection pooling, you may want to get in the habit of dropping temporary tables immediately after use.

Global temporary tables, on the other hand, since they are visible to all users in a given database, are destroyed along with the last connection which references them

try this

IF OBJECT_ID('tempdb..##Temp02', 'U') IS NOT NULL
   drop TABLE ##Temp02
