我有以下需要作为exec语句的一部分运行的SQL。我正在努力的是让撇号正确。如果我只用1个撇号运行它，那么该语句就可以正常运行，并且我认为有2个可以将它转义出来，从而允许它工作。撇号，使用EXEC处理
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
')
我得到的错误是：
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'.

它可能会帮助您打印您尝试执行的语句并手动对其执行可视化扫描。例如，当我这样做时，它可以让我很容易地看到第5行的错误：'FROM sys.dm_os_sys_info）Uptime，'在这里语法不正确。我相信你的查询的开始应该是'SELECT（SELECT'），你在这里省略了第二个“select”。如果你调整了它，你的查询运行良好。 – ZLK
