[jira] [Updated] (SPARK-30049) SQL fails to parse when comment
contains an unmatched quote character
[ https://issues.apache.org/jira/browse/SPARK-30049?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Hyukjin Kwon updated SPARK-30049:
---------------------------------
Target Version/s: (was: 3.0.0)
> SQL fails to parse when comment contains an unmatched quote character
> ---------------------------------------------------------------------
>
> Key: SPARK-30049
> URL: https://issues.apache.org/jira/browse/SPARK-30049
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 3.0.0
> Reporter: Jason Darrell Lowe
> Priority: Major
>
> A SQL statement that contains a comment with an unmatched quote character can lead to a parse error. These queries parsed correctly in older versions of Spark. For example, here's an excerpt from an interactive spark-sql session on a recent Spark-3.0.0-SNAPSHOT build (commit e23c135e568d4401a5659bc1b5ae8fc8bf147693):
> {noformat}
> spark-sql> SELECT 1 -- someone's comment here
> > ;
> Error in query:
> extraneous input ';' expecting <EOF>(line 2, pos 0)
> == SQL ==
> SELECT 1 -- someone's comment here
> ;
> ^^^
> {noformat}
