public StatementInterface::fetchCol($index = 0) Returns an entire single column of a result set as an indexed array. Note that this method will run the result set to the end.

public StatementInterface::fetchAssoc() Fetches the next row and returns it as an associative array. This method corresponds to PDOStatement::fetchObject(), but for associative arrays. For some reason PDOStatement does not have a corresponding array helper method, so one is added. Return value An associative array, or FALSE if there is no next row.

public StatementInterface::fetchAllKeyed($key_index = 0, $value_index = 1) Returns the entire result set as a single associative array. This method is only useful for two-column result sets. It will return an associative array where the key is one column from the result set and the value is another field. In most cases, the default of the first two columns is appropriate. Note that this method will run the result set to the end. Parameters $key_index: The numeric index of the field to use as t

public StatementInterface::fetchAllAssoc($key, $fetch = NULL) Returns the result set as an associative array keyed by the given field. If the given key appears multiple times, later records will overwrite earlier ones. Parameters $key: The name of the field on which to index the array. $fetch: The fetchmode to use. If set to PDO::FETCH_ASSOC, PDO::FETCH_NUM, or PDO::FETCH_BOTH the returned value with be an array of arrays. For any other value it will be an array of objects. By default, the fet

StatementInterface::fetchAll($mode = NULL, $column_index = NULL, $constructor_arguments = NULL) Returns an array containing all of the result set rows. Parameters $mode: One of the PDO::FETCH_* constants. $column_index: If $mode is PDO::FETCH_COLUMN, the index of the column to fetch. $constructor_arguments: If $mode is PDO::FETCH_CLASS, the arguments to pass to the constructor.

public StatementInterface::fetch($mode = NULL, $cursor_orientation = NULL, $cursor_offset = NULL) Fetches the next row from a result set. See http://php.net/manual/pdo.constants.php for the definition of the constants used. Parameters $mode: One of the PDO::FETCH_* constants. Default to what was specified by setFetchMode(). $cursor_orientation: Not implemented in all database drivers, don't use. $cursor_offset: Not implemented in all database drivers, don't use. Return value A result, formatt

public StatementInterface::execute($args = array(), $options = array()) Executes a prepared statement Parameters $args: An array of values with as many elements as there are bound parameters in the SQL statement being executed. $options: An array of options for this query.
