Applies to: SQL Server Azure SQL Database Azure SQL Managed Instance Azure Synapse Analytics Analytics Platform System (PDW)

This function returns the name of a specified database.

Transact-SQL syntax conventions


DB_NAME ( [ database_id ] )  


To view Transact-SQL syntax for SQL Server 2014 (12.x) and earlier versions, see Previous versions documentation.



The identification number (ID) of the database whose name DB_NAME will return. If the call to DB_NAME omits database_id, DB_NAME returns the name of the current database.

Return types



If the caller of DB_NAME does not own a specific non-master or non-tempdb database, ALTER ANY DATABASE or VIEW ANY DATABASE server-level permissions at minimum are required to see the corresponding DB_ID row. For the master database, DB_ID needs CREATE DATABASE permission at minimum. The database to which the caller connects will always appear in sys.databases.


By default, the public role has the VIEW ANY DATABASE permission, which allows all logins to see database information. To prevent a login from detecting a database, REVOKE the VIEW ANY DATABASE permission from public, or DENY the VIEW ANY DATABASE permission for individual logins.


A. Returning the current database name

This example returns the name of the current database.

SELECT DB_NAME() AS [Current Database];  

B. Returning the database name of a specified database ID

This example returns the database name for database ID 3.

USE master;  
SELECT DB_NAME(3) AS [Database Name];  

Examples: Azure Synapse Analytics and Analytics Platform System (PDW)

C. Return the current database name

SELECT DB_NAME() AS [Current Database];  

D. Return the name of a database by using the database ID

This example returns the database name and database_id for each database.

FROM sys.databases;
