The feature of Contained Databases introduced with SQL Server 2012 and SQL DBAs are using this feature for those databases which are frequently required to move between SQL Server Instances. If you don’t know about Contained database, please read previous two articles.

In this post, I am sharing a T-SQL script to convert your current database to Partially Contained Database of SQL Server.

You can also change this setting using SSMS, Right click on Database -> Options -> Containment type -> Partial

Enable Contained Database feature at instance level:

EXEC sp_configure 'contained database authentication', 1;
GO
RECONFIGURE ;
GO

Alter your database for CONTAINMENT:

EXEC sp_configure 'contained database authentication', 1;
GO
RECONFIGURE ;
GO

In the previous article, I shared a small note on SQL Server 2012 Contained Database. In this script, I am sharing a script to enable Contained Database at an instance level.

Without enabling this option, you cannot create a Contained Database in SQL Server 2012. Use sp_configure to enable it and require option is ‘contained database authentication.’

Below is a script:

Use master
GO
sp_configure 'show advanced options', 1
GO
RECONFIGURE WITH OVERRIDE
GO 
sp_configure 'contained database authentication', 1
GO
RECONFIGURE WITH OVERRIDE
GO 
sp_configure 'show advanced options', 0 
GO
RECONFIGURE WITH OVERRIDE 
GO

SQL Server 2012 introduced a feature like Contained Database which stores all the metadata information of your database in itself; it is not storing into a master database.

If you defined your database as contained database, it is isolated from the other database. Whenever you need to move your database from one instance to another instance, a contained database is the best option because you do not require to migrate information like Database users separately.

Before creating an any contained database, you must enable it at an instance level. You can create a user to access the Contained Database.

In the next post, I will share T-SQL script to enable contained database at instance level so DBA can access this post in SQL Server DBA category.

Using SSMS, You can also create a contained database like right click on database -> New Database… -> Option -> Containment type -> Partial

T-SQL Script to create a contained database:

CREATE DATABASE db_name
CONTAINMENT = PARTIAL
GO

In this post, I am sharing a TSQL script to find the list of uncontained objects of a Database of SQL Server.

SQL Server 2012 introduced a new concept of partial, contained databases to access few elements from outside its boundary.

As per the MSDN official document, uncontained objects are those objects that cross the database boundaries in a contained database.

Below is a TSQL script:

SELECT 
	O.name
	,O.type_desc
	,DDUE.class_desc
	,DDUE.statement_line_number
	,DDUE.statement_type
	,DDUE.feature_name
	,DDUE.feature_type_name
FROM sys.dm_db_uncontained_entities AS DDUE
LEFT JOIN sys.objects AS O
ON DDUE.major_id = O.object_id
