I want to generate create table script of already created table in my live database.

I know we can generate scripts usin开发者_运维知识库g right click on table and click on 'script table as' menu and script will be generated. Because my live db UI is running very slow.

I want to do same process using SQL query. is there any way??

If you are looking for a TSQL solution, it is quite verbose, as this example shows.

A shorter alternative would be using the SMO library (example)

(I originally answered this here, but SQL Server-only devs probably do not relate the question title to this problem)

For a more complete(-ish) solution for generating a CREATE TABLE statement with indexes, triggers and constraints try the stored procedure made by Lowell Izaguirre.

It has been tested and developed since 2004, last update was in 2013.

I've also made some improvements to include index options (PAD_INDEX, FILLFACTOR, IGNORE_DUP_KEY):

here are the changes, can't fit all the code so you'll find the complete modified version at http://pastebin.com/LXpBeuN1 .

Update

I've talked with Lowell and a new version will be online soon with the new changes for index options and other improvements.

Use this query :

DROP FUNCTION [dbo].[Get_Table_Script]
Go

Create Function Get_Table_Script
(
    @vsTableName varchar(50)
)

Returns
    VarChar(Max)
With ENCRYPTION

Begin

Declare @ScriptCommand varchar(Max)

Select @ScriptCommand =
    ' Create Table [' + SO.name + '] (' + o.list + ')' 
    +
    (
        Case
        When TC.Constraint_Name IS NULL 
            Then ''
        Else 'ALTER TABLE ' + SO.Name + ' ADD CONSTRAINT ' +
            TC.Constraint_Name  + ' PRIMARY KEY ' + ' (' + LEFT(j.List, Len(j.List)-1) + ')'
        End
    )
From sysobjects As SO
    Cross Apply

    (
        Select 
            '  [' + column_name + '] ' + 
             data_type + 
             (
                Case data_type

            ) As j (list)
Where
    ( xtype = 'U' )
    AND 
    ( Name NOT IN ('dtproperties') )

Return @ScriptCommand

End

And you can fire this Function like this :

Select [dbo].Get_Table_Script '<Your_Table_Name>'

And for create trigger use this

SELECT     
DB_NAME() AS DataBaseName,                  
dbo.SysObjects.Name AS TriggerName,
dbo.sysComments.Text AS SqlContent
FROM 
dbo.SysObjects INNER JOIN 
    dbo.sysComments ON 
    dbo.SysObjects.ID = dbo.sysComments.ID
WHERE   
(dbo.SysObjects.xType = 'TR') 
AND 
dbo.SysObjects.Name LIKE '<Trigger_Name>'
