How do I list all the columns in a table?

For the various popular database systems, how do you list all the columns in a table?

Solution 1:

For MySQL, use:

DESCRIBE name_of_table;

This also works for Oracle as long as you are using SQL*Plus, or Oracle's SQL Developer.

For Oracle (PL/SQL)

SELECT column_name
FROM user_tab_cols
WHERE table_name = 'myTableName'

For MySQL

SHOW COLUMNS FROM table_name

For MS SQL Server:

select * from information_schema.columns where table_name = 'tableName'

(5 years laters, for the Honor of PostgreSQL, the most advanced DDBB of the Kingdom)

In PostgreSQL:

\d table_name

Or, using SQL:

select column_name, data_type, character_maximum_length
    from INFORMATION_SCHEMA.COLUMNS 
    where table_name = 'table_name';
