Sql server 我可以从临时表创建函数视图吗

我可以使用下面的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

如果只是因为要执行大量插入和其他操作，则无法从该视图创建视图。视图是从单个查询创建的

关于用户定义函数：您不能使用动态SQL，您正在执行以下操作：

EXEC ('UPDATE #T1 SET Bookings = ' + @Bookings11 + ',Revenue=' + @Revenue11 + 
    ',Area = ' + @Area11 + ' WHERE EnquiryDate = ' + '''' +  @BookingDate + 
    ''' AND PID =' +  @ProjectId1)    

您也不能使用临时表。此处记录了这两个限制：

但是，您可以在存储过程中完成所有这些事情。还可以将存储过程的输出定向到临时表或表变量，从而允许您在另一个查询中使用该输出：

INSERT INTO dbo.MyTable
(MyTableId, Column1, Column2) -- arbitrary-chosen column names
EXEC  dbo.MyStoredProcedure 

SELECT *
FROM   dbo.MyTable 
WHERE  Column1 = 'Some Value'

最后，您可能能够重新编写SQL以使用表变量，而不是临时表，这是允许的。在我看来，您的动态SQL不需要是动态的，所以您也可以消除这种情况

希望这能有所帮助。
