![Topic link icon](../../database-engine/configure-windows/media/topic-link.gif "Topic link icon") [Transact-SQL Syntax Conventions](../../t-sql/language-elements/transact-sql-syntax-conventions-transact-sql.md)
  
## Syntax  
  
```sql
DB_NAME ( [ database_id ] )  
```  
  
## Arguments  
*database_id*  
Is the identification number (ID) of the database to be returned. *database_id* is **int**, with no default. If no ID is specified, the current database name is returned.
  
## Return types
**nvarchar(128)**
  
## Permissions  
If the caller of **DB_NAME** is not the owner of the database and the database is not **master** or **tempdb**, the minimum permissions required to see the corresponding row are ALTER ANY DATABASE or VIEW ANY DATABASE server-level permission, or CREATE DATABASE permission in the **master** database. The database to which the caller is connected can always be viewed in **sys.databases**.
  
> [!IMPORTANT]  
>  By default, the public role has the VIEW ANY DATABASE permission, allowing all logins to see database information. To block a login from the ability to detect a database, REVOKE the VIEW ANY DATABASE permission from public, or DENY the VIEW ANY DATABASE permission for individual logins.  
  
## Examples  
  
### A. Returning the current database name  
The following example returns the name of the current database.
  
```sql
SELECT DB_NAME() AS [Current Database];  
GO  
```  
  
### B. Returning the database name of a specified database ID  
The following example returns the database name for database ID `3`.
  
```sql
USE master;  
GO  
SELECT DB_NAME(3)AS [Database Name];  
GO  
```  
  
## Examples: [!INCLUDE[ssSDWfull](../../includes/sssdwfull-md.md)] and [!INCLUDE[ssPDW](../../includes/sspdw-md.md)]  
  
### C. Return the current database name  
  
```sql
SELECT DB_NAME() AS [Current Database];  
```  
  
### D. Return the name of a database by using the database ID  
The following example returns the database name and database_id for each database.
  
```sql
SELECT DB_NAME(database_id) AS [Database], database_id  
FROM sys.databases;  
```
