我有以下需要作爲exec語句的一部分運行的SQL。我正在努力的是讓撇號正確。如果我只用1個撇號運行它，那麼該語句就可以正常運行，並且我認爲有2個可以將它轉義出來，從而允許它工作。撇號，使用EXEC處理
任何想法？
exec
('
SELECT COALESCE(NULLIF(CAST((DATEDIFF(mi,sqlserver_start_time,GetDate())/1440) as varchar),''0'') + '' day(s), '','''')
+ COALESCE(NULLIF(CAST(((DATEDIFF(mi,sqlserver_start_time,GetDate())%1440)/60) as varchar),''0'') + '' hour(s), '','''')
+ CAST((DATEDIFF(mi,sqlserver_start_time,GetDate())%60) as varchar) + ''min'' as Uptime
FROM sys.dm_os_sys_info) as Uptime,
CAST(LEFT((RIGHT(@@version, LEN(@@version)- 3 -charindex ('' ON '',@@VERSION))),CHARINDEX(''<'',(RIGHT(@@version, LEN(@@version)- 3 -charindex ('' ON '',@@VERSION))),0)-2) as nvarchar(300)) as OS,
cast(serverproperty(''MachineName'') as nvarchar(255)) MachineName,
cast(serverproperty(''ServerName'') as nvarchar(255)) ServerInstanceName,
cast(LEFT(@@VERSION,CHARINDEX(''('',@@VERSION,0)-2) as nvarchar(300)) as Version,
cast(replace(cast(serverproperty(''Edition'')as varchar),''Edition'','''') as varchar(max)) Edition,
cast(serverproperty(''productVersion'') as nvarchar(255)) ProductBuildLevel,
cast(serverproperty(''productLevel'') as nvarchar(255)) SPLevel,
cast(serverproperty(''Collation'') as nvarchar(255)) CollationType,
cast(serverproperty(''IsClustered'') as nvarchar(255)) [IsClustered],
cast((select physical_memory_kb/1024 FROM sys.dm_os_sys_info) as int) AS PhysicalMemory,
cast((select value from sys.configurations where name = ''min server memory (MB)'') as int) as MinMemory,
cast((select value from sys.configurations where name = ''max server memory (MB)'') as int) as MaxMemory,
cast((select cpu_count FROM sys.dm_os_sys_info) as int) AS LogicalCPUCount,
cast((select hyperthread_ratio FROM sys.dm_os_sys_info) as int) AS HyperthreadRatio,
cast((select cpu_count/hyperthread_ratio FROM sys.dm_os_sys_info) as int) AS PhysicalCPUCount
')
我得到的錯誤是：
Msg 102, Level 15, State 1, Line 5
Incorrect syntax near ')'.
Msg 156, Level 15, State 1, Line 15
Incorrect syntax near the keyword 'as'.

它可能會幫助您打印您嘗試執行的語句並手動對其執行可視化掃描。例如，當我這樣做時，它可以讓我很容易地看到第5行的錯誤：'FROM sys.dm_os_sys_info）Uptime，'在這裏語法不正確。我相信你的查詢的開始應該是'SELECT（SELECT'），你在這裏省略了第二個「select」。如果你調整了它，你的查詢運行良好。 – ZLK
