Sql 案例陈述不是'；Don’我不参加会议

这是我的问题

SELECT migrationref,
       dbo.Firstnamecheck(firstname, contacttype)         AS FirstNameCheck,
       dbo.Lastnamecheck(lastname, contacttype)           AS LastNameCheck,
       dbo.Corporatenamecheck(corporatename, contacttype) AS CorporateNameCheck,
       dbo.Advisercheck(adviser, advisermigrationref)     AS AdviserCheck
INTO   ##clientvalidcheck
FROM   clientimports

DELETE FROM ##clientvalidcheck
WHERE  ( firstnamecheck IS NULL
         AND lastnamecheck IS NULL
         AND corporatenamecheck IS NULL
         AND advisercheck IS NULL );

SELECT *
FROM   ##clientvalidcheck

SELECT CASE firstnamecheck
         WHEN 'ERROR' THEN 'FirstName caused an Error.'
       END "FNValidationError"
FROM   ##clientvalidcheck; 

据我所知，当您使用case语句时，它会在表的末尾添加一列以显示语句的结果，但对我来说，它会生成一个不属于表的新列。还有什么可以加入这两者的吗

使用：

Select A1.*, CASE A1.FirstNameCheck WHEN 'ERROR' THEN 'FirstName caused an Error.' END "FNValidationError"
FROM ##ClientValidCheck  A1;

喜欢修改吗

Select t1.*, CASE t1.FirstNameCheck WHEN 'ERROR' THEN 'FirstName caused an Error.' END "FNValidationError"
FROM ##ClientValidCheck  t1;

您使用的是MySQL还是MS SQL Server？请不要标记未涉及的产品。如果这是您想要的，您需要在select*中包含

大小写

，而不是作为单独的语句。@jarlh抱歉，我只使用MS SQL Server您似乎在说您需要一个新列，但实际上您得到了一个您不需要的新列？请注意“，”在案件之前；）
