PDO::query --  Executes an SQL statement, returning a result set as a PDOStatement object

Syntax

object PDO::query ( string statement )

Warning

This function is EXPERIMENTAL. The behaviour of this function, the name of this function, and anything else documented about this function may change without notice in a future release of PHP. Use this function at your own risk.

PDO::query() prepares and executes an SQL statement in a single function call, returning the result set (if any) returned by the statement as a PDOStatement object.

For a SELECT statement that you need to issue multiple times, prepare a PDOStatement object with PDO::prepare() and issue the statement with PDOStatement::execute().

Parameters

statement

The SQL statement to prepare and execute.

Return Values

PDO::query() returns a PDOStatement object.

Examples

Example 1. Demonstrate PDO::query

A nice feature of PDO::query() is that it enables you to iterate over the rowset returned by a successfully executed SELECT statement.

<?php
function getFruit($conn) {
    
$sql = 'SELECT name, colour, calories FROM fruit ORDER BY name';
    foreach (
$conn->query($sql) as $row) {
        print
$row['NAME'] . "\t";
        print
$row['COLOUR'] . "\t";
        print
$row['CALORIES'] . "\n";
    }
}
?>

The above example will output:

apple   red     150
banana  yellow  250
kiwi    brown   75
lemon   yellow  25
orange  orange  300
pear    green   150
watermelon      pink    90
