PDOStatement::debugDumpParams Dump an SQL prepared command

Description

bool PDOStatement::debugDumpParams ( void )

Dumps the informations contained by a prepared statement directly on the output. It will provide the SQL query in use, the number of parameters used (Params), the list of parameters, with their name, type (paramtype) as an integer, their key name or position, the value, and the position in the query (if this is supported by the PDO driver, otherwise, it will be -1).

This is a debug function, which dump directly the data on the normal output.

Tip

As with anything that outputs its result directly to the browser, the output-control functions can be used to capture the output of this function, and save it in a string (for example).

This will only dumps the parameters in the statement at the moment of the dump. Extra parameters are not stored in the statement, and not displayed.

Return Values

No value is returned.

Examples

Example #1 PDOStatement::debugDumpParams() example with named parameters

<?php
/* Execute a prepared statement by binding PHP variables */
$calories 150;
$colour 'red';
$sth $dbh->prepare('SELECT name, colour, calories
    FROM fruit
    WHERE calories < :calories AND colour = :colour'
);
$sth->bindParam(':calories'$caloriesPDO::PARAM_INT);
$sth->bindValue(':colour'$colourPDO::PARAM_STR12);
$sth->execute();

$sth->debugDumpParams();

?>

The above example will output:

 SQL: [96] SELECT name, colour, calories  FROM fruit  WHERE calories < :calories AND colour = :colour Params: 2 Key: Name: [9] :calories paramno=-1 name=[9] ":calories" is_param=1 param_type=1 Key: Name: [7] :colour paramno=-1 name=[7] ":colour" is_param=1 param_type=2 

Example #2 PDOStatement::debugDumpParams() example with unnamed parameters

<?php

/* Execute a prepared statement by binding PHP variables */
$calories 150;
$colour 'red';
$name 'apple';

$sth $dbh->prepare('SELECT name, colour, calories
    FROM fruit
    WHERE calories < ? AND colour = ?'
);
$sth->bindParam(1$caloriesPDO::PARAM_INT);
$sth->bindValue(2$colourPDO::PARAM_STR);
$sth->execute();

$sth->debugDumpParams();

?>

The above example will output:

 SQL: [82] SELECT name, colour, calories  FROM fruit  WHERE calories < ? AND colour = ? Params: 2 Key: Position #0: paramno=0 name=[0] "" is_param=1 param_type=1 Key: Position #1: paramno=1 name=[0] "" is_param=1 param_type=2
