Question

以下查询弹出此错误名称＆＃39;名称＆＃39;在这种情况下是非法的。这里只允许使用常量，常量表达式或变量。列名是非法的。

为什么？

 INSERT INTO UPGRADEd
         (SCRIPT_CODE,
        APP_NAME, 
        FILE_NAME,
        DATE_APPLIED,
        ACT_TYPE,
        STATUS,
          CREDENTIALS)
        VALUES
        ( 'scriptcode',
        '-appname-',
        '-filename-',
        getdate(),
       'PC',
       (select 
       case when count(1) = 1 then 'FAIL' else 'OK' end from sysobjects
       where name = ''),
       (select hostname from sysprocesses where spid = @@spid)
       )

您不能将insert .. values与insert..select混在一起。您应该将所有内容放在select语句中，如下所示

INSERT INTO UPGRADEd
(  SCRIPT_CODE, APP_NAME, FILE_NAME, DATE_APPLIED,
   ACT_TYPE, STATUS, CREDENTIALS) 
select 'scriptcode','-appname-','-filename-',getdate(),
       'PC', 
       case 
       when count(1) = 1 
         then 'FAIL' 
       else 'OK' end,
       (select hostname from sysprocesses where spid = @@spid) 
from sysobjects
where name = ''
