我可以使用以下查询创建视图或函数吗？它使用临时表。我无法创建视图或函数。

答案 0 :(得分：0)
如果只是因为您正在执行大量插入操作和其他操作，则无法从中创建视图。视图是从单个查询创建的。
关于用户定义的函数：您不能使用正在执行的动态SQL：
EXEC ('UPDATE #T1 SET Bookings = ' + @Bookings11 + ',Revenue=' + @Revenue11 +
',Area = ' + @Area11 + ' WHERE EnquiryDate = ' + '''' + @BookingDate +
''' AND PID =' + @ProjectId1)
您也无法使用临时表。这两个限制都记录在这里：http://msdn.microsoft.com/en-us/library/ms191320.aspx。
但是，您可以在存储过程中执行所有这些操作。也可以将存储过程的输出定向到临时表或表变量，允许您在另一个查询中使用输出：
INSERT INTO dbo.MyTable
(MyTableId, Column1, Column2) -- arbitrary-chosen column names
EXEC dbo.MyStoredProcedure
SELECT *
FROM dbo.MyTable
WHERE Column1 = 'Some Value'
最后，您可以重新编写SQL以使用表变量而不是临时表，这是允许的。它也让我觉得你的动态SQL不需要是动态的，所以你也可以消除它。
希望这有帮助。
