How to copy table from Production to Development? - sql

Question

I am working on Development Server Named as SQLDEV01 and the db name is University and the table name is cse.students. During my work on table cse.students I lost some rows so I need to get the all the exact data from Production server.production Server Name is SQLPROD01.
How can I query to get the production data without using SSIS?

Answer 1

Setup a linked server from the development to production servers before doing the following from SSMS. All code should be executed on the development server.
http://technet.microsoft.com/en-us/library/ms188279.aspx
-- On Development server [SQLDEV01]
TRUNCATE TABLE [University].[cse].[students];
GO
-- Use link server to move data
INSERT INTO
[University].[cse].[students]
SELECT
*
FROM
[SQLPROD01].[University].[cse].[students]
GO
This assumes there are no identity columns on the target.
If you do have identity columns, turn on/off allow inserts before/after executing the above insert.
-- Before Insert, execute this statement
SET IDENTITY_INSERT [University].[cse].[students] ON
GO
-- After Insert, execute this statement
SET IDENTITY_INSERT [University].[cse].[students] OFF
GO
You can also create an ad-hoc connection using the OPENROWSET command.
http://technet.microsoft.com/en-us/library/ms190312.aspx
INSERT INTO
[University].[cse].[students]
SELECT
PRD.*
FROM
OPENROWSET('SQLNCLI', 'Server=SQLPROD01;Trusted_Connection=yes;',
'SELECT * FROM [University].[cse].[students]') AS PRD;
I did not check the syntax for your environment, please check.
If add hoc queries are set off (0), have the DBA turn them on (1) temporarily. Execute the following on the production server.
http://msdn.microsoft.com/en-us/library/ms187569.aspx
-- Show all settings
sp_configure 'show advanced options', 1;
RECONFIGURE;
GO
-- What is the current setting?
sp_configure
GO
-- Allow add hoc queries
sp_configure 'Ad Hoc Distributed Queries', 1;
RECONFIGURE;
GO
If (s)he does not allow that, you are stuck with a physical linked server.
If you are using delegation - choice #3, you have to watch out for the double hop issue.

I would configure the linked server with a specific account on production that has rights to select the data. See choice #4.

There are a few ways to do this. One that is pretty much failsafe is the following:
In Microsoft SQL Management Studio expand the server node for the source server - Then expand the Databases node. Right click on the source database and select Tasks -> Generate Scripts. When the dialog pops up click next. Select the "Select specific database objects" radio button. Expand the Tables node as check the table you want to copy. Click the next button at the bottom. Click the advanced button. In the options that pop up for Script DROP and CREATE select Script DROP and CREATE on the right. For the option Type of data to script select schema and data on the right. Click OK. Now back on the main dialog you need to select "Save to Clipboard" or "Save to new query window". I usually select clipboard because I am usually going to a different server but select what works best for you. Click next. Click next again and the script will generate according to your selections. Now just run that script on the destination database.

please use this query generalized query by replacing your entries
select * into targetTable from [sourceserver].[sourcedatabase].[dbo].[sourceTable]
