Executing Stored procedure with Codeigniter 2 & Oracle 11g

Question

Its been an hour I m having trouble executing oracle stored procedures in Codeigniter 2. I m not being able to find proper documentation for CI+Stored procedures.

My Stored Procedure :

CREATE OR REPLACE 
PROCEDURE SP_DISTRICT_INSERT(P_DST_NAME VARCHAR2, FLAG VARCHAR2 Default '0',P_USER_ID Number) AS

PKEY NUMBER:=0;

         BEGIN

             SELECT MAX(NVL(DST_ID,0))+1 INTO PKEY FROM DISTRICT ;

      INSERT INTO DISTRICT(DST_ID, DST_NAME, USER_ID, ENTERED_DATE, FLAG) VALUES(PKEY,P_DST_NAME,P_USER_ID,SYSDATE ,FLAG);

     COMMIT ;



EXCEPTION

        WHEN OTHERS THEN

 RAISE_APPLICATION_ERROR (-20001,PKEY|| 'INVALID_NO'|| P_DST_NAME|| 'DATAMISMATCH'|| SQLERRM, TRUE) ;

END SP_DISTRICT_INSERT ;

AND I executed stored procedure in my model like this

$ins=$this->db->query("call SP_DISTRICT_INSERT('abcdxyz',1,1)");

The page showing error

Error Number:

call SP_DISTRICT_INSERT('abcdxyz',1,1)

Filename: D:\xampp\htdocs\..\database\DB_driver.php

Line Number: 330

However,

If i call procedure directly from Navicat, it works

Any help will be appreciated.

P.S. I m using Codeigniter 2 and Oracle 11g

Thanks

Well the problem was database field length. The scenario is that after form submission, the input string is converted into unicode format like . So if database field length is 10 and i input string with 4 characters, the procedure returned error because 4 characters when converted into unicode format becomes around 24 characters which is bigger than the allowed length in database field.
