[jira] [Updated] (FLINK-25631) Support enhanced `show tables` statement
[ https://issues.apache.org/jira/browse/FLINK-25631?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Yubin Li updated FLINK-25631:
-----------------------------
Description:
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_name.]database_name ] [ [NOT] LIKE regex_pattern ]
