判断临时表/正式表是否存在？

--判断临时表是否存在 
IF EXISTS ( SELECT  *
            FROM    tempdb..sysobjects
            WHERE   id = OBJECT_ID('tempdb..#Frequency') )
    PRINT 'yes'; 

IF EXISTS ( SELECT  *
            FROM    tempdb.dbo.sysobjects
            WHERE   id = OBJECT_ID(N'tempdb..#Frequency')
                    AND type = 'U' )
    PRINT 'yes';

--判断数据表是否存在
IF OBJECT_ID(N'tablename', N'U') IS NOT NULL
    PRINT '存在';
ELSE
    PRINT '不存在';
