Dongjoon Hyun updated SPARK-27903:
----------------------------------
Affects Version/s: (was: 3.0.0)
3.1.0
> Improve parser error message for mismatched parentheses in expressions
> ----------------------------------------------------------------------
>
> Key: SPARK-27903
> URL: https://issues.apache.org/jira/browse/SPARK-27903
> Project: Spark
> Issue Type: Sub-task
> Components: SQL
> Affects Versions: 3.1.0
> Reporter: Yesheng Ma
> Priority: Major
>
> When parentheses are mismatched in expressions in queries, the error message
> is confusing. This is especially true for large queries, where mismatched
> parens are tedious for human to figure out.
> For example, the error message for
> {code:sql}
> SELECT ((x + y) * z FROM t;
> {code}
> is
> {code:java}
> mismatched input 'FROM' expecting ','(line 1, pos 20)
> {code}
> One possible way to fix is to explicitly capture such kind of mismatched
> parens in a grammar rule and print user-friendly error message such as
> {code:java}
> mismatched parentheses for expression 'SELECT ((x + y) * z FROM t;'(line 1,
> pos 20)
> {code}
