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)

表中存储的语句是临时语句，可以是 SELECT TOP 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.JobDetailJobStart, 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.JobDetailJobStart, JD.JobDetailJobEnd) + 1) -(DATEDIFF(wk, JD.JobDetailJobStart, 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))
    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

我想执行从T-SQL声明的 @Query 变量。这可能吗？（我正在运行MSSQL 2005环境）
