Открытые методы

Метод	Описание
__call ( string $name, array $arguments ) : ORM	Magic method to capture calls to undefined class methods.
__callStatic ( string $name, array $arguments ) : ORM	Magic method to capture calls to undefined static class methods.
__get ( $key )	--------------------- //
__isset ( $key )
__set ( $key, $value )
__unset ( $key )
_setup_limit_clause_style ( string $connection_name )	Detect and initialise the limit clause style ("SELECT TOP 5" / ".
as_array ( )	Return the raw data wrapped by this ORM instance as an associative array. Column names may optionally be supplied as arguments, if so, only those keys will be returned.
associative ( ) : ORM	Set the ORM instance to return associative results sets
avg ( string $column )	Tell the ORM that you wish to execute a AVG query.
clear_cache ( )	Clear the query cache
configure ( string $key, mixed $value = null, string $connection_name = self::DEFAULT_CONNECTION )	Pass configuration settings to the class in the form of key/value pairs. As a shortcut, if the second argument is omitted and the key is a string, the setting is assumed to be the DSN string used by PDO to connect to the database (often, this will be the only configuration required to use Idiorm). If you have more than one setting you wish to configure, another shortcut is to pass an array of settings (and omit the second argument).
count ( $column = '*' )	Tell the ORM that you wish to execute a COUNT query.
create ( $data = null )	Create a new, empty instance of the class. Used to add a new row to your database. May optionally be passed an associative array of data to populate the instance. If so, all fields will be flagged as dirty so all will be saved to the database when save() is called.
delete ( )	Delete this record from the database
delete_many ( $join = false, $table = false )	Delete many records from the database Added: could delete many of a join query, if you define $join to true and the table where you want to delete the records
distinct ( )	Add a DISTINCT keyword before the list of columns in the SELECT query
find_array ( ) : array	Tell the ORM that you are expecting multiple results from your query, and execute it. Will return an array, or an empty array if no rows were returned.
find_many ( ) : array | granada\ResultSet	Tell the ORM that you are expecting multiple results from your query, and execute it. Will return an array of instances of the ORM class, or an empty array if no rows were returned.
find_one ( $id = null )	Tell the ORM that you are expecting a single result back from your query, and execute it. Will return a single instance of the ORM class, or false if no rows were returned.
find_result_set ( ) : granada\ResultSet	Tell the ORM that you are expecting multiple results from your query, and execute it. Will return a result set object containing instances of the ORM class.
for_table ( string $table_name, string $connection_name = self::DEFAULT_CONNECTION ) : ORM	Despite its slightly odd name, this is actually the factory method used to acquire instances of the class. It is named this way for the sake of a readable interface, ie ORM::for_table('table_name')->find_one()-> etc. As such, this will normally be the first method called in a chain.
force_all_dirty ( )	Force the ORM to flag all the fields in the $data array as "dirty" and therefore update them when save() is called.

This can be called if any low-level DB access is required outside the class. If multiple connections are used, accepts an optional key name for the connection.
get_last_query ( null | string $connection_name = null ) : string	Get the last query executed. Only works if the 'logging' config option is set to true. Otherwise this will return null. Returns last query from all connections if no connection_name is specified
get_last_statement ( ) : PDOStatement	Returns the PDOStatement instance last used by any connection wrapped by the ORM.
get_query_log ( string $connection_name = self::DEFAULT_CONNECTION )	Get an array containing all the queries run on a specified connection up to now.

group_by_expr ( string $expr )	Add an unquoted expression to the list of columns to GROUP BY
having ( $column_name, $value )	Add a HAVING column = value clause to your query. Each time this is called in the chain, an additional HAVING will be added, and these will be ANDed together when the final query is built.
