;;; Commentary:
|
|
|
|
;; Org-Babel support for evaluating sql source code.
|
|
;;
|
|
;; SQL is somewhat unique in that there are many different engines for
|
|
;; the evaluation of sql (Mysql, PostgreSQL, etc...), so much of this
|
|
;; file will have to be implemented engine by engine.
|
|
;;
|
|
;; Also SQL evaluation generally takes place inside of a database.
|
|
;;
|
|
;; For now lets just allow a generic ':cmdline' header argument.
|
|
;;
|
|
;; TODO:
|
|
;;
|
|
;; - support for sessions
|
|
;; - add more useful header arguments (user, passwd, database, etc...)
|
|
;; - support for more engines (currently only supports mysql)
|
|
;; - what's a reasonable way to drop table data into SQL?
