Provide sqlite database access over osc.
Might be useful as a way to access a database from SuperCollider. Note that all communication is asynchronous. Will support only basic CRUD operations. The useage might be:
(tid is always a unique transaction id to group returned values and manage stuff because of its asynchronous nature)
/db/status-- return database status (connected/disconnected)/db/query tid sql_string-- execute query (for inserts, ...)/db/select tid tablename fields where order-- select rows from table, answer with an osc-message for each row to the same address
For a later implementation:
/database/select-- select database to use/database/connect-- "connect" to database (open file)/database/disconnect-- close connection to database (yet don't end node-server!)
(Run the node-osc-server in the terminal by node oscsqlite.js after defining the path to a database file in line 3.)
o = OscSqlite()
d = (field1: "This is", field2: "a little test");
o.insert("mytable", d);
o.select({ |data|
"callback:".postln;
data.postln;
}, "mytable", "*", "id <= 3", "id DESC");
o.update("mytable", (field2: "a big test"), "id = 1");
o.delete("mytable", "id = 1");
Uses node-osc and node-sqlite3, install with npm:
npm install node-osc
npm install sqlite3All stuff is (c) 2012 by Benjamin Graf, but feel free to do whatever you want with it. E-Mail: [email protected] Web: http://www.bennigraf.de
