Generate Table Definition In SQL Server Without GUI

This script will create table definition along with unique key, primary key and indexes.

Don’t you like to have a stored procedure handy like sp_helptext to generate table definitions for you from the query window without switching over to the SSMS object explorer? Here it is, I have created a stored procedure called GetTableCreateScript. Using this procedure, you can get the table definitions including primary key, unique and non-clustered indexes on the query window itself like sp_helptext

How to Use it.

Open SQL Server management studio, select appropriate database and create “GetTableCreateScript" stored procedure. After creating procedure, run the stored procedure as mentioned in the below image.


Below is entire script. 

aLTER Proc GetTableCreateScript
(@TableName varchar(150))
as
Begin
