问题 I have several tables that already exist in my database. Some of them have quite a few columns. I want to make some stored procedures to do a merge statement with these tables. To do that I would like the parameter of the stored procedure to be a User Defined Table type. I can go script out each table and modify it to a User Defined Table Type Creation statement. But what I would really like is a way to generate a user defined table type off an existing table in my database. I could then add

问题 I am trying to customise the default query which is put in place when you click New Stored Procedure... from the Object Explorer on SQL Server Management Studio 2008. I have found how to change the 'Create Stored Procedure (New Menu)' template from the Template Explorer , however this means I will have to keep opening the template explorer rather than clicking on new stored procedure like i usually would.

I want to more a bit more internals, but not too deep. :-) thanks in advance, George 回答1: Heap storage has nothing to do with these heaps. Heap just
