I have written a little ESQL function:
| Code: |
CREATE FUNCTION Traverse(IN inRef REFERENCE, IN outRef REFERENCE) RETURNS BOOLEAN
BEGIN
SET Environment.start='start';
BEGIN
DECLARE EXIT HANDLER FOR SQLSTATE LIKE '%'
BEGIN
DECLARE state CHARACTER SQLSTATE;
SET Environment.handler = 'handler';
-- do something
WHILE some_condition DO
IF Traverse(inRef, outRef) THEN
-- do something
ELSE
RETURN FALSE;
END IF;
END WHILE;
RETURN TRUE;
END;
END;
SET Environment.end = 'end';
RETURN FALSE;
END; |
When I run/debug the flow, the handler code is never entered.
Is it because the compiler has prevented using a handler recursively or have I done something wrong?
Broker version 6.1.0.5, tested on AIX

Well this code is the body of the HANDLER:
| Code: |
DECLARE EXIT HANDLER FOR SQLSTATE LIKE '%'
BEGIN
DECLARE state CHARACTER SQLSTATE;
SET Environment.handler = 'handler';
-- do something
WHILE some_condition DO
IF Traverse(inRef, outRef) THEN
-- do something
ELSE
RETURN FALSE;
END IF;
END WHILE;
RETURN TRUE;
END; |
And I see no code that could cause an exception that would cause the exception handler block to be entered.
Kind regards,

Thanks,
Yes, I was putting the try code in the catch block. |
