ShowTablesCommand

case class ShowTablesCommand(databaseName: Option[String], tableIdentifierPattern: Option[String], isExtended: Boolean = false, partitionSpec: Option[TablePartitionSpec] = None) extends LogicalPlan with RunnableCommand with Product with Serializable

A command for users to get tables in the given database. If a databaseName is not given, the current database will be used. The syntax of using this command in SQL is:

SHOW TABLES [(IN|FROM) database_name] [[LIKE] 'identifier_with_wildcards'];
SHOW TABLE EXTENDED [(IN|FROM) database_name] LIKE 'identifier_with_wildcards'
[PARTITION(partition_spec)];
