->limit()

->limit() – Set limit

Synopsis

void $DB_DataObject->limit ( int $from , int $number )

Description

Sets the limit for a query. (this only works on databases that support the LIMIT clause), without parameters, it will clear the current limit.

Parameter

  • int $from - limit start (or number), or blank to reset

  • int $number - limit results to number

Note

This function can not be called statically.

Since postgres and mysql only really support limit directly - calling this on an unsupported database will emit a PEAR::Error and die.

Example

Setting the Limit

<?php
$person 
= new DataObjects_Person;
$person->limit(2);
$person->find();
while (
$person->fetch()) {
    echo 
"{$person->id} {$person->name}<BR>";
}


$person = new DataObjects_Person;
$person->limit(2,4);
$person->find();

while (
$person->fetch()) {
    echo 
"{$person->id} {$person->name}<BR>";
}
?>

Resulting SQL

        
SELECT * FROM person LIMIT 2

SELECT * FROM person LIMIT 2,4
