----------------------------------------
I'm wondering if this needs to be supported by Calcite and if that's indeed the
case, if Calcite already supports this.
> Support enhanced `show tables` statement
> ----------------------------------------
>
> Key: FLINK-25631
> URL: https://issues.apache.org/jira/browse/FLINK-25631
> Project: Flink
> Issue Type: New Feature
> Components: Table SQL / API
> Affects Versions: 1.14.4
> Reporter: Yubin Li
> Priority: Major
>
> Enhanced `show tables` statement like ` show tables from db1 like 't%' ` has
> been supported broadly in many popular data process engine like
> presto/trino/spark
> [https://spark.apache.org/docs/latest/sql-ref-syntax-aux-show-tables.html]
> I have investigated the syntax of engines as mentioned above.
>
> We could use such statement to easily show the tables of specified databases
> without switching db frequently, alse we could use regexp pattern to find
> focused tables quickly from plenty of tables. besides, the new statement is
> compatible completely with the old one, users could use `show tables` as
> before.
> h3. SHOW TABLES [ ( FROM | IN ) [catalog.]db ] [ [NOT] LIKE regex_pattern ]
