Generating create table script (with indexes, keys, constrains) for all tables in SQL Server database

If I run the following script

SELECT so.Name, sc.开发者_Python百科Text
FROM syscomments sc JOIN sysobjects so ON sc.ID = so.ID

I will get all the create procedure/function scripts. Is there something like this for tables, indexes, keys, and triggers?

Thank you for your help!


Nothing inbuilt.

To do it in T-SQL You'd need to find or write your own script. Example here that might get you started.


for SQL 2012 and later use this

I have tried many scripts in web. All of them had flaws. I finally wrote my script using a post in msdn site and changed it to work on many kind of situations.

Note: This scripts works on SQL Server 2012 and later
