存储过程中对于文本是两个单引号，而不是一个单引号或者一个双引号

刚开始以为是一个单引号，或者是一个双引号， 没想到是两个单引号，郁闷

例如下面

SET @SQLOne = '
INSERT INTO #ddlist(DDGuid,HBGUID,EnumDDLY,DDType,LYDH,DJBH,RQ,SJJE,WLFY,SumMoney,Audit,Auditor,AuditTime,Record,RecordTime)
SELECT dbo.DD.Guid AS DDGuid, dbo.DD.HBGUID, (CASE dbo.DD.DDLY WHEN 0 THEN ''系统网站'' WHEN 1 THEN ''淘宝网站'' WHEN 2 THEN ''其他'' WHEN 3 THEN ''淘宝分销'' WHEN 4 THEN ''拍拍网站''  
        WHEN 5 THEN ''京东商城'' WHEN 6 THEN ''当当网站'' WHEN 7 THEN ''E链通'' WHEN 8 THEN ''商派网站'' WHEN 9 THEN ''POS门店''  
        WHEN 10 THEN ''商派分销王'' WHEN 11 THEN ''一号店'' WHEN 12 THEN ''凡客商城'' WHEN 13 THEN ''品聚网站'' WHEN 14 THEN ''卓越亚马逊''   
        WHEN 16 THEN ''邮乐商城'' WHEN 17 THEN ''好乐买'' WHEN 18 THEN ''QQ网购'' WHEN 19 THEN ''QQ彩贝'' WHEN 20 THEN ''阿里巴巴'' WHEN 21 THEN ''优购''  
        WHEN 22 THEN ''新蛋网'' WHEN 23 THEN ''聚美优品'' WHEN 24 THEN ''商派易开店''     
        WHEN 100 THEN ''乐蜂网''  WHEN 101 THEN ''ERPFX'' END)  
                       AS EnumDDLY, ''销售订单'' AS DDType,LYDH,dbo.DD.DJBH,pt.SMRQ AS RQ,SJJE,WLFY,ISNULL(SJJE,0)+ISNULL(WLFY, 0)-ISNULL(RLJE,0) AS SumMoney, 0  AS Audit,null AS Auditor, NULL AS AuditTime,0 as Record, NULL AS RecordTime 
                       FROM dbo.DD
                       LEFT OUTER JOIN dbo.DD_ShenHe AS SH WITH(NOLOCK) ON dbo.DD.GUID = SH.GUID
                       LEFT OUTER JOIN dbo.DD_Delivery AS Dli WITH(NOLOCK) ON dd.GUID = Dli.GUID
                       LEFT OUTER JOIN dbo.DD_Print AS pt WITH(NOLOCK) ON dd.GUID = pt.GUID
                       WHERE ISNULL(Dli.FH, 0) = 1 AND

EXEC(@SQLOne);
