如何使用T-SQL执行保存在表中的SQL语句

是否可以使用T-sql执行存储在表中的sql语句？

DECLARE @Query text
SET @Query = (Select Query FROM SCM.dbo.CustomQuery)

存储在表中的语句是ad-hoc语句,可以是SELECT AT 100 * FROM ATable到更复杂的语句：

Select
J.JobName As Job,JD.JobDetailJobStart AS StartDate,JD.JobDetailJobEnd AS EndDate,(
    SELECT (DATEDIFF(dd,JD.JobDetailJobStart,JD.JobDetailJobEnd) + 1) -(DATEDIFF(wk,JD.JobDetailJobEnd) * 2) -(CASE WHEN DATENAME(dw,JD.JobDetailJobStart) = 'Sunday' THEN -1 ELSE 0 END) -(CASE WHEN DATENAME(dw,JD.JobDetailJobEnd) = 'Saturday' THEN -1 ELSE 0 END)
) AS NumberOfWorkingDays,JD.JobDetailDailyTarget AS DailyTarget,JD.JobDetailWeeklyTarget AS WeeklyTarget,JD.JobDetailrequiredQTY AS requiredQuantity,(
    Select SUM(sJL.JobLabourQuantityEmployees) From JobLabour sJL
) AS NumberOfEmployees,(
    Select 
        SUM((sEM.EmployeeDesignationDefaultRate * sJL.JobLabourQuantityEmployees)*8)*(SELECT (DATEDIFF(dd,JD.JobDetailJobEnd) = 'Saturday' THEN -1 ELSE 0 END))
    from EmployeeDesignation sEM
    Inner join JobLabour sJL on sJL.EmployeeDesignationID = sEM.EmployeeDesignationID
) AS FullEmployeeRate



from Job J
Inner Join JobDetail JD on JD.JobID = J.JobID
Inner Join JobLabour JL on JL.JobID = J.JobID

WHERE J.JobActive = 0

我想执行我从T-sql声明的@Query变量.这可能吗？ (我正在运行MSsql 2005环境)

解决方法

您可以使用

EXECUTE sp_executesql @Query

运行你的T-sql
