Where I can check user-define table type in SQL Server 2008 in SSMS? and how can I insert new column into it?

Question

I need to add some more columns into my current user-define table type in SQL Server 2008

But I didn't see any table type in particular database under Tables .

Where exactly I need to check and how can I modify the design of existing user-define table type in SQL Server 2008

I'm using SQL SERVER 2008 and SSMS

Where I can find that table in SSMS ,

so that I can go and modify table type.

thanks

Answer 1

User-defined types cannot be modified after they are created, because changes could invalidate data in the tables or indexes. To modify a type, you must either drop the type and then re-create it, or issue an ALTER ASSEMBLY statement by using the WITH UNCHECKED DATA clause. For more information, see ALTER ASSEMBLY (Transact-SQL).

Points to take care while using user defined table type

1.Default values are not allowed.

2.Primary key must be a persisted column.

3.Check constraint can not be done on non persisted computed columns

4.Non clustered indexes are not allowed.

5.It can't be altered. You have to drop and recreate it.
