Milan Dankovic created SPARK-55119:
--------------------------------------
Summary: CONTINUE handler should not interrupt conditional if
exception thrown by previous statement
Key: SPARK-55119
URL: https://issues.apache.org/jira/browse/SPARK-55119
Project: Spark
Issue Type: Sub-task
Components: Spark Core
Affects Versions: 4.2.0
Reporter: Milan Dankovic
When a CONTINUE HANDLER is triggered by an exception thrown from a statement
that comes before a conditional statement (IF, WHILE, REPEAT, CASE, etc.) in a
loop body, the conditional statement is incorrectly interrupted even though its
condition has not been evaluated yet.
This script fails with [INTERNAL_ERROR] No more elements to iterate through:
{code:java}
BEGIN
DECLARE nomorerows BOOLEAN DEFAULT FALSE;
DECLARE CONTINUE HANDLER FOR DIVIDE_BY_ZERO
SET nomorerows = TRUE;
REPEAT
SELECT 1/0; -- Throws exception
IF NOT nomorerows THEN -- Gets incorrectly interrupted
SELECT 100;
END IF;
UNTIL nomorerows
END REPEAT;
SELECT 'done' as status;
END; {code}
