PL/JSON v0.6.1 has now been released to Sourceforge.net. The reason for the .1 is that I forgot a dependency on the 0.6 release.

Anyway, PL/JSON can now create JSON via the API or through parsing a text string. The parser is implemented as a stand along package. That means you can write your own parser (or use an external procedure) if you don’t like mine. This will make it very extensible. I also plan to add PL/SQL callbacks to the parser at some point for custom processing.

Example of parsing:

SET SERVEROUTPUT ON

DECLARE
  v_json json;
  v_json2 VARCHAR2(32000) :=
   '{
      "abc": "dpkxvdvvcxz\"vxasasa   ",
      "def": 12345,
      "ghi":{"isit":true, "nope":false,"denada":true },
      "jkl": [1234, 45678.99, 121211, 21323232, 00000]
   }';
BEGIN

  v_json := json(v_json2);
  v_json.print;
END;
/

{
"abc":"dpkxvdvvcxz\"vxasasa   ",
"def":12345,
"ghi":{
"isit":true,
"nope":false,
"denada":true}
,
"jkl":[1234,45678.99,121211,21323232,0]}

Output from PL/JSON checks out on JSONLint.

Update March 29, 2009:  PL/JSON is now available as an open source project (MIT License).  Read the FAQ at http://oracleoss.com

Do you use JSON? Do you use Oracle? How would you like to use JSON in Oracle? How would you like to store it, generate it and read it? I am creating a new JSON data type that will work like XMLType.

I am assuming you are familiar with Oracle (or you probably wouldn’t be reading this blog). If you are not familiar with JSON it is JavaScript Object Notation, a lightweight data-interchange specification. Think of it as a replacement to XML.
