EXCEPTION HANDLING & RE-THROW EXCEPTION IN HANA

Hello,

How can i handle exceptions in HANA SQL Stored procedure?  I want to capture all exceptions, log errors into a table and then re-throw the exceptions to the client application.  How can I do that?

Here is the one i have been trying for long time. But no luck.

========================================

SET SCHEMA JEDAR_1;


--DROP TABLE ERR_TABLE;
CREATE ROW TABLE ERR_TABLE
(
          ROW_ID INT PRIMARY KEY,          SQL_ERROR_CODE INT,          SQL_ERROR_MESSAGE VARCHAR(5000),          PROCEDURE_NAME VARCHAR(5000),          PARAMETERS VARCHAR(5000),          SYSDATE DATE
);


CREATE SEQUENCE ERR_TABLESeq RESET BY SELECT IFNULL(MAX(ROW_ID), 0) + 1 FROM ERR_TABLE;


--DROP PROCEDURE "SaveParams" ;


CREATE PROCEDURE "SaveParams" 
(
          IN p_threshold INT           ,IN p_str_keys VARCHAR           ,IN p_wrd_keys VARCHAR  
) LANGUAGE SQLSCRIPT AS 
BEGIN           DECLARE myParams VARCHAR(5000);          DECLARE errCode INT;          DECLARE errMsg VARCHAR(5000);          DECLARE MYCOND CONDITION;          DECLARE EXIT HANDLER FOR SQLEXCEPTION           BEGIN                     SELECT TO_VARCHAR(p_threshold) || '#' || p_str_keys || '#' || p_wrd_keys, ::SQL_ERROR_CODE, ::SQL_ERROR_MESSAGE INTO myParams, errCode, errMsg                     FROM DUMMY;                  --STORED ERROR DETAILS INTO ERR TABLE AND THEN EXIT FROM PROCEDURE                    INSERT INTO ERR_TABLE (ROW_ID, SQL_ERROR_CODE, SQL_ERROR_MESSAGE, PROCEDURE_NAME, PARAMETERS, SYSDATE)                              VALUES (ERR_TABLESeq.NEXTVAL, :errCode, :errMsg, 'SaveParams', :myParams, CURRENT_DATE);                 -- RE-THROWING THE EXCEPTION                     RESIGNAL;            END;            SELECT 1/0 FROM DUMMY;  


END;


CALL "SaveParams" (1, 'KEY1,KEY2', 'KEY3,KEY4');


SELECT * FROM ERR_TABLE;
