Question

I am using this query in api

if (isset($json['version'])) {
        $client_cache_version =  @$json['version'];

        $version_sql = $db->quoteInto("SELECT max(messageVersion) as version FROM messageTable");
        $version_results = $db->fetchAll($version_sql);

        $version_array = $version_results['0'];

        $max_version = $version_array['version'];

        if($max_version > $client_cache_version){

            $sql = $db->quoteInto("SELECT * FROM messageTable");
            $results = $db->fetchAll($sql);

            $count = array(
                'count' => sizeof($results)
            );

all code working fine but problem in

$version_sql = $db->quoteInto("SELECT max(messageVersion) as version FROM messageTable");

when i try to check this code on curl I got this error

Answer 1

From the Zend API on Db_Adapter_Pdo_Mysql::quoteInto():

The placeholder is a question-mark; all placeholders will be replaced with the quoted value. For example:

$text = "WHERE date < ?";
$date = "2005-01-02";
$safe = $sql->quoteInto($text, $date);
// $safe = "WHERE date < '2005-01-02'"

Parameters
Name   Type     Description
$text  string   The text with a placeholder.
$value mixed    The value to quote. 
$type  string   OPTIONAL SQL datatype
$count integer OPTIONAL count of placeholders to replace

Returns
Type    Description
string  An SQL-safe quoted value placed into the original text.

Note that the value is REQUIRED. You shouldn’t be using this method if you’re not binding any params.
