DRILL-5419: Calculate return string length for literals & some stringâ¦
⦠functions
1. Revisited calculation logic for string literals and some string
functions (cast, upper, lower, initcap, reverse, concat, concat operator,
substring, substr, left, right, rpad, lpad, case statement, coalesce,
first_value, last_value).
2. Deprecated width and changed it to precision for string types.
3. Synchronized return type length calculation logic between limit 0 and
regular queries.
4. Performed minor refactoring, added appropriate unit tests.
