Yesheng Ma updated SPARK-27906:
-------------------------------
Description:
{{SHOW VIEW}} statement is actually not supported in Spark SQL. However, when a
user quries such a statement, the error message is confusing. For example, the
error message for
{code:sql}
SHOW VIEWS IN my_database
{code}
is
{code:java}
missing 'FUNCTIONS' at 'IN'(line 1, pos 11)
{code}
which is misleading.
One possible way to fix is to explicitly capture these statements in a grammar
rule and print user-friendly error message such as
{code:java}
SHOW VIEW statements are not supported.
{code}
