Detailed Description

This is a "fake" PDOStatement implementation that behaves mostly like a real statement object, but has some additional features:

• Parameters passed to execute() are quoted according to their PHP type.
• A PHP NULL value will result in an actual SQL NULL value in the query.
• Array types are supported for all placeholders ("WHERE value IN (?)").
• Positional and named parameters can be mixed in the same query.

Constructor & Destructor Documentation

__construct	(		$db,
			$query,
			$options
	)

Initializes a new StudipPDOStatement instance.

Member Function Documentation

__call	(		$name,
		array	$arguments
	)

Forwards all unknown methods to the actual statement object.

bindColumn	(		$column,
		&	$param
	)

Arranges to have a particular variable bound to a given column in the result-set from a query. Each call to fetch() or fetchAll() will update all the variables that are bound to columns.

bindParam	(		$parameter,
		&	$variable,
			$data_type = PDO::PARAM_STR
	)

Binds a PHP variable to a corresponding named or question mark place- holder in the SQL statement that was used to prepare the statement. Unlike bindValue(), the variable is bound as a reference and will only be evaluated at the time that execute() is called.

bindValue	(		$parameter,
			$value,
			$data_type = PDO::PARAM_STR
	)

Binds a value to a corresponding named or question mark placeholder in the SQL statement that was used to prepare the statement.

Here is the caller graph for this function:

execute

(

$input_parameters = NULL

)

Executes the prepared statement and returns a PDOStatement object.

Reimplemented in StudipDebugPDOStatement.

Here is the call graph for this function:

fetchGrouped	(		$fetch_style = PDO::FETCH_ASSOC,
			$fetch_argument = 0
	)

Returns the result set rows as a grouped associative array. The first field of each row is used as the array's keys.

Parameters

int	$fetch_style	Either PDO::FETCH_ASSOC or PDO::FETCH_COLUMN
mixed	$fetch_argument	Unused for FETCH_ASSOC, field index to fetch for FETCH_COLUMN

getIterator

(

)

Forwards all Iterator methods to the actual statement object.

replaceParam (   $matches )

protected

Replaces a placeholder with the corresponding parameter value. Throws an exception if there is no corresponding value.

setStatement

(

PDOStatement

$statement

)

Injects a PDOStatement
