MySQL and PostgreSQL rosetta stone

This is a short table of useful and common MySQL & PostgreSQL commands put up against each other.



Command line client mysql psql
Connect to database use mysql; \connect postgresql;
List databases show databases; \l
List tables show tables; \dt
Describe table describe table; \d table;
Show server version select version(); select version();
Show the current time select now(); select now();
Authentication GRANT ALL PRIVILEGES ON *.* TO ‘monty’@’localhost’; (http://dev.mysql.com/doc/refman/5.5/en/adding-users.html) Edit pg_hba.conf (http://wiki.postgresql.org/wiki/Client_Authentication)
Check user privileges SHOW GRANTS FOR ‘root’@’localhost’; \du (List all users and their permission levels)
Backup mysqldump [options] db_name [tbl_name …] pg_dump [option…] [dbname]

Note for future: This reference list will grow.




Table shows correctly in Mozilla Firefox but it does not in Google Chrome or any other Webkit browser for that matter. Go figure.
