= mydbi
http://github.com/andynu/mydbi
== DESCRIPTION:
A simple wrapper for dbi that provides two simple functions,
and auth profiles via a configuration file.
== FEATURES/PROBLEMS:
* PROBLEM: no tests => I have some, but they point at local databases and I have not gotten around to making nice mocky ones.
== SYNOPSIS:
DISCLAMER: The DBI api is fine and in most contexts should be used directly.
I wrote it as a little helper for the hundreds of tiny csv outputers,
backfills, and other assorted one-off sys-admin data munghing scripts scripts
that I write. This script intoduces three methods into the Object namespace, it
should not be used in a larger project. Please keep that in mind.
A simple wrapper for dbi that provides two simple functions:
dbconnect(dbname="test", host="localhost", user="root", pass="")
dbconnect(profile_key)
uses my most common defaults
query(sql, *values)
which returns the last_insert_id() for auto increment table inserts
and yields row when selecting.
ascii_query(sql, *values)
select query output much like mysql's commandline client
== Config file $HOME/.mydbirc
A yaml configuration file for named database connections
---
:databaseone:
:name: db_one
:host: localhost
:username: root
:password:
:databasetwo:
:name: db_two
:host: other_host
:username: root
:password: secret
Then you can pass the symbol is as the db name
db1 = dbconnect(:databaseone)
db2 = dbconnect(:databasetwo)
== Example:
require 'mydbi'
dbconnect(:databaseone)
lastn_id = query("insert into lastn (id, ord, song_id) values (null, 1, 10)");
query("select * from lastn") do |row|
puts row.inspect
end
