How to get a table creation statement in MS SQLServer

zhaozj2021-02-08  267

MS SQLServer can only get the creation statement of the stored procedure, the method is as follows:

Sp_helptext ProcedureName

But often we need to get the creation statement of the table. For example, it is said that a table has changed when the database is upgraded, or there is already a table, but do not know what it is, there is no constraint, there is a primary key , Which indexes have been created. I will give a stored procedure for the reader's reference.

This stored procedure can get all the creative statements of all the tables you want, including the creation statement of the index associated with the table.

Code under SQLServer2000
