Code
public function findTables($table_expression) { $tables = []; // The SQLite implementation doesn't need to use the same filtering strategy // as the parent one because individually prefixed tables live in their own // schema (database), which means that neither the main database nor any // attached one will contain a prefixed table name, so we just need to loop // over all known schemas and filter by the user-supplied table expression. $attached_dbs = $this->connection->getAttachedDatabases(); foreach ($attached_dbs as $schema) { // Can't use query placeholders for the schema because the query would // have to be :prefixsqlite_master, which does not work. We also need to // ignore the internal SQLite tables. $result = $this->connection->query("SELECT name FROM " . $schema . ".sqlite_master WHERE type = :type AND name LIKE :table_name AND name NOT LIKE :pattern", array( ':type' => 'table', ':table_name' => $table_expression, ':pattern' => 'sqlite_%', )); $tables += $result->fetchAllKeyed(0, 0); } return $tables; }
