Altering user-defined table types in SQL Server

Question

How can I alter a user-defined table type in SQL Server ?

Answer 1

Simon Zeinstra has found the solution!

But, I used Visual Studio community 2015 and I didn't even have to use schema compare.

Using SQL Server Object Explorer, I found my user-defined table type in the DB. I right-mouse clicked on the table-type and selected . This opened a code tab in the IDE with the TSQL code visible and editable. I simply changed the definition (in my case just increased the size of an nvarchar field) and clicked the Update Database button in the top-left of the tab.

Hey Presto! - a quick check in SSMS and the udtt definition has been modified.

Brilliant - thanks Simon.
