Michael J. Carey created ASTERIXDB-2595:
-------------------------------------------
Summary: Positional vars and array indexes are inconsistent in
SQL++
Key: ASTERIXDB-2595
URL: https://issues.apache.org/jira/browse/ASTERIXDB-2595
Project: Apache AsterixDB
Issue Type: Bug
Components: *DB - AsterixDB, SQL - Translator SQL++
Affects Versions: 0.9.4.1
Reporter: Michael J. Carey
Assignee: Dmitry Lychagin
Fix For: 0.9.5
Positional variables in SQL++ seem to start at 1 -- while array indexes start
at 0 -- this is pretty annoying in a use case like:
CREATE FUNCTION grade(score) {
LET stdcutoffs = [96.5, 93.5, 90.0, 86.5, 83.5, 80.0, 76.5, 73.5, 70.0, 66.5,
63.5, 60.0, 0.0],
grades = [“A+“, “A”, “A-“, “B+“, “B”, “B-“, “C+“, “C”, “C-“, “D+“,
“D”, “D-“, “F”]
FROM grades AS g AT i
WHERE score >= stdcutoffs[i-1]
SELECT VALUE g
ORDER BY i ASC
LIMIT 1
};
