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)
您可以使用
EXECUTE sp_executesql @Query
运行您的T-SQL
