SQLServer 中的存储过程中判断临时表是否存在，存在则删除临时表

IF OBJECT_ID('TEMPDB..#BCROSSREFERENCE ') IS NOT NULL
DROP TABLE #BCROSSREFERENCE
IF OBJECT_ID('TEMPDB..#SCVTMP_BCUSTOMER') IS NOT NULL
DROP TABLE #SCVTMP_BCUSTOMER
IF OBJECT_ID('TEMPDB..#PDS_CREATE_SCV_TEMP') IS NOT NULL
DROP TABLE #PDS_CREATE_SCV_TEMP
IF OBJECT_ID('TEMPDB..#MASTER_NOTIN_LCSTSA') IS NOT NULL
DROP TABLE #MASTER_NOTIN_LCSTSA
IF OBJECT_ID('TEMPDB..#MASTER_NOTIN_LCSTCCG') IS NOT NULL
DROP TABLE #MASTER_NOTIN_LCSTCCG

　　

ALTER TABLE #TEMP3 ADD ID INT IDENTITY(1,1)

给临时表加上自增ID
