如何在SQL Server 2005中使用动态查询创建临时表

Question

I want to create Temporary table dynamically in SQL Server 2005 like below.

Create Table ##EmpMonthlyTimeReport
(
    EmpID UNIQUEIDENTIFIER,
    EmpName VARCHAR(100),
    TaskId UNIQUEIDENTIFIER,
    [07 Nov] NVARCHAR(10),
    [08 Nov] NVARCHAR(10),
    [09 Nov] NVARCHAR(10)
)

In the above ##EmpMonthlyTimeReport table, columns [07 Nov], [08 Nov], [09 Nov] are NOT static. They are creating dynamically through another function.

Hence, I am dynamically constructing the above table in one variable called @EmpMonthlyTimeReport and I'm executing the constructed sql string like below:

EXEC(@EmpMonthlyTimeReport)

I am getting the following error:

Msg 50000, Level 16, State 1, Procedure SVS_WorkOnWeekends, Line 157
The name 'INSERT INTO ##EmpMonthlyTimeReport(EmpID, EmpName, TaskId)
SELECT EmpId, EmpName, TaskId FROM TableData 
SELECT * FROM ##EmpMonthlyTimeReport
DROP TABLE ##EmpMonthlyTimeReport' is not a valid identifier.

Very silly work around.

I have changed the @EmpMonthlyTimeReport variable declaration from VARCHAR(MAX) to NVARCHAR(MAX)

That's it. Everything is working as expected.
