sysdatabases

master database only

Description

sysdatabases contains one row for each database in Adaptive Server. When Adaptive Server is installed, sysdatabases contains entries for the master database, the model database, the sybsystemprocs database, and the tempdb database. If you have installed auditing, it also contains an entry for the sybsecurity database.

Columns

The columns for sysdatabases are:

1	0x0001	You specified the proxy_update option, and the database is a user-created proxy database.
2	0x0002	Database is a proxy database created by high availability.
4	0x0004	Database has a proxy database created by high availability.
8	0x0008	Disallow access to the database, since database is being shut down.
