To get list of databases in ASE:
We can get the list of databases(system and user databases) either using sp_helpdb or sysdatabases. Sysdatabases table gives us more information than sp_helpdb, but doesnt provide the segment information. sp_databases procedures gives only database name, size information.
To get particular database information:
Syntax: sp_helpdb database_name
Example:
sp_helpdb k2schools
Output:
To get all databases(system databases and user databases) information:
sp_helpdb
Using System Table: We can get databases information using sysdatabases table. But, this can be run only on master database or use master..sysdatabases.
To get particular database information:
Example1:
1> use k2schools
2> go
1> select * from sysdatabases where name = ‘k2schools’
2> go
To get all databases(system databases and user databases) information:
1> select *from sysdatabases
2> go
To get only databases(system databases and user databases) names:
1> select name from sysdatabases
2> go
name
