$table yii\db\TableSchema

The table metadata
findSchemaNames() protected method (available since version 2.0.4)

Returns all schema names in the database, including the default one but not system schemas.

This method should be overridden by child classes in order to support this feature because the default implementation simply throws an exception.

All schema names in the database, except system schemas
findTableNames() protected method

Returns all table names in the database.

protected array findTableNames ( $schema = '' )

return array

All table names in the database. The names have NO schema name prefix.
findUniqueIndexes() public method

Returns all unique indexes for the given table.

Each array element is of the following structure:

[
    'IndexName1' => ['col1' [, ...]],
    'IndexName2' => ['col2' [, ...]],
]
