Question

我想用表变量中的参数调用SQL函数，但是当我调用它时我得到了错误

子查询返回的值超过1个

因为表有多行。如何从表变量中逐行调用函数？

这是我的代码：

    DECLARE @FromDate NVARCHAR(10) = '20150809',
    @ToDate NVARCHAR(10) = '20150815',
    @EmpID NVARCHAR(6)= '000752'

    DECLARE @AttendanceTable TABLE(date NVARCHAR(30),Funckey NVARCHAR(10))
    insert into @AttendanceTable(date,Funckey) SELECT date,Funckey from PERS_Attendance WHERE DATE between convert(date,@fromDate) AND CONVERT(Date,@toDate)

    select * FROM @AttendanceTable

select dbo.SM_GetScheduleIn(@EmpID,(select date from @AttendanceTable))

Answer 1

select dbo.SM_GetScheduleIn(@EmpID,(select date from @AttendanceTable))

应该是

select dbo.SM_GetScheduleIn(@EmpID,date) from @AttendanceTable

子查询返回多个值/调用带有变量表参数的标量值函数
