# PDO::query

Executes an SQL statement, returning a result set as a PDOStatement object

### Description

public PDOStatement PDO::query ( string `$statement` )
public PDOStatement PDO::query ( string `$statement` , int `$PDO::FETCH_COLUMN` , int `$colno` )
public PDOStatement PDO::query ( string `$statement` , int `$PDO::FETCH_CLASS` , string `$classname` , array `$ctorargs` )
public PDOStatement PDO::query ( string `$statement` , int `$PDO::FETCH_INTO` , object `$object` )

PDO::query 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 query that you need to issue multiple times, you will realize better performance if you prepare a PDOStatement object using PDO::prepare and issue the statement with multiple calls to PDOStatement::execute.

If you do not fetch all of the data in a result set before issuing your next call to PDO::query, your call may fail. Call PDOStatement::closeCursor to release the database resources associated with the PDOStatement object before issuing your next call to PDO::query.

> Note:

> Although this function is only documented as having a single parameter, you may pass additional arguments to this function. They will be treated as though you called PDOStatement::setFetchMode on the resultant statement object.

### Parameters

`statement`

  The SQL statement to prepare and execute.

  Data inside the query should be properly escaped.

### Return Values

PDO::query returns a PDOStatement object, or `FALSE` on failure.

### 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) {
$sql = 'SELECT name, color, calories FROM fruit ORDER BY name';
foreach ($conn->query($sql) as $row) {
print $row['name'] . "\t";
print $row['color'] . "\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
