----------------------------------

             Summary: Spark SQL can't treat bracketed comments well and lead to generated golden files can't display bracketed comments well.
                 Key: SPARK-30758
                 URL: https://issues.apache.org/jira/browse/SPARK-30758
             Project: Spark
          Issue Type: Sub-task
          Components: SQL
    Affects Versions: 3.0.0
            Reporter: jiaan.geng


Although Spark SQL support bracketed comments, but {{SQLQueryTestSuite}} can't treat bracketed comments well and lead to generated golden files can't display bracketed comments well.

We can read the output of comments.sql

[https://github.com/apache/spark/blob/master/sql/core/src/test/resources/sql-tests/results/postgreSQL/comments.sql.out]

Such as:

 
{code:java}
