[SOLVED] How can I get emacs sql-mode to use the mysql config file (.my.cnf)?

How can I get emacs sql-mode to use the mysql config file (.my.cnf)?

When I type mysql dbname at the bash prompt, I automatically connect to the database dbname with the username, password, and host information included in my .my.cnf file.

When I use M-x sql-mysql in emacs, I am asked for all of this information again.

Is there a way that I can get emacs sql mode to use the information in my .my.cnf file?

Solution

I don't think that this is possible but you can set such stuff in the mode configuration itself:

(setq sql-connection-alist
'((pool-a
(sql-product 'mysql)
(sql-server "1.2.3.4")
(sql-user "me")
(sql-password "mypassword")
(sql-database "thedb")
(sql-port 3306))
(pool-b
(sql-product 'mysql)
(sql-server "1.2.3.4")
(sql-user "me")
(sql-password "mypassword")
(sql-database "thedb")
(sql-port 3307))))

(defun sql-connect-preset (name)
  "Connect to a predefined SQL connection listed in `sql-connection-alist'"
  (eval `(let ,(cdr (assoc name sql-connection-alist))
    (flet ((sql-get-login (&rest what)))
      (sql-product-interactive sql-product)))))

(defun sql-pool-a ()
  (interactive)
  (sql-connect-preset 'pool-a))
