sql - From a Sybase Database, how I can get table description ( field names and types)?

Question

I have access to command line isql and I like to get Meta-Data of all the tables of a given database, possibly in a formatted file. How I can achieve that?

Thanks.

Answer 1

Check sysobjects and syscolumns tables.

Here is a diagram of Sybase system tables.

List of all user tables:

SELECT * FROM sysobjects WHERE type = 'U'

You can change 'U' to other objects:

• C – computed column
• D – default
• F – SQLJ function
• L – log
• N – partition condition
• P – Transact-SQL or SQLJ procedure
• PR – prepare objects (created by Dynamic SQL)
• R – rule
• RI – referential constraint
• S – system table
• TR – trigger
• U – user table
• V – view
• XP – extended stored procedure

List of columns in a table:

SELECT sc.* 
FROM syscolumns sc
INNER JOIN sysobjects so ON sc.id = so.id
WHERE so.name = 'my_table_name'
