Generate script and restore

Sometime we need to copy remote MS SQL database from one server to another server but we do not save permissions to RDP (Remote desktop) on server. Here I will show, how you can do it with help of SSMS (SQL Server Management Studio)  generate script option.

You need to follow these steps. 

1.       Generate database script of source database (Schema and data)

2.       Take a backup of target database with help of generate database script as first step

3.       Drop all db objects of target database

4.       Restore step 1 generated script in target database  

Generate database script

This Generate Script step will be helpful for our main step 1 and 2. You can use these steps to generate  source database script (for restore) and target database script (for backup) follow these steps

Step 1

Right-click on your database and select Task -> generate script.

Step 2

Click next in the introduction screen.

Step 3

Select the database object which you are all you need and then click next.

Step 4

Now you will be shown a window which asks you about how your script should be published.

Click advanced in that window.

Step 5

Select ‘Schema and data’ from type of data to script option and then click OK.

Click next.

Step 6

Click finish, now check the script file, it must be having the insert queries too.

 Script with schema and data will be saved in "C:\Temp\DataScript.sql". Now you get source database script for restore. Now you follow the same steps and take the backup of target database and after that we will restore source database into target database.

Drop all db objects

Now we will delete all the database object in targeted database with help of below script. We can delete these database objects from database 

1. Store procedures
2. Views
3. Functions
4. Tables

Restore database script

Once all the database objects dropped then we will run the source database generated script into targeted database. Which we have created in first step.

We will restore database with help of “sqlcmd utility”. Need to open cmd prompt and type below command

sqlcmd -S targetdatabase -i "C:\Temp\DataScript.sql" -d TargetDatabase -U userid -P password

Press enter it will restore all your database.

All these steps completed now you can check the targeted database updated with source database. Hope it will help you

Keep sharing keep learning. Thank you
