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