View Database

There are multiple ways to view a database. You can view system tables or use system stored procedures.

SELECT type_desc,

Name,

Physical_name,

Size,

Max_size,

Growth

FROM sys. database_files -- view system a. sys. database_files

GO

Sp_helpdb

The storage process sp_helpdb provides the ability to view basic database information. It is actually an encapsulation of several t-SQL commands.

These commands extract data from related system tables to obtain basic database information.

Syntax:

Sp_helpdb Database Name
