T-SQL Tips and Tricks: Copying Views from one database to multiple target databases

By Database Admin  at Feb 26, 2024  0 Comments

If you are a MS SQL Database developer or Database Administrator then you may run into this situation. You have created a SQL View and you have to make it available in multiple databases. A simple way is to open each database and run your script.

Our team at SharpQuest maintains more than dozen databases for each environment - development, QA, Preproduction and production. And executing scripts in multiple databases during development or testing becomes a time consuming and many times manual process.

To make our developers' life easy we have created few routines that comes handy to the DBA to copy views and routines from one DB to another DB. 

If you need a script to copy [Stored Procedure or Functions] from one database to another then follow this article. https://www.sharpquest.com/blog/posts/2024/march/t-sql-copying-stored-procedure-or-function-from-one-database-to-multiple-target-databases/

Following is the script to copy VIEW from one SQL DB to another. You can modify and use for your own purpose. If you modify with features that can be useful to others, please comment here or share with us so.

 

/*
	sharpquest.copy_view
		-- copies a SQL View from current database to target database(s)
	example:
		exec sharpquest.copy_view 'dbo.vCustomer', 'customer_db'
		-- above will copy the view vCustomer to a target database customer_db on same sql server that you have access to 
		exec sharpquest.copy_view 'dbo.vCustomer', 'qa_'
		-- above will copy the view vCustomer to all databases whose name starts with [qa_] on same sql server that you have access to
