mysqli and multi_query not working - php

Question

<?php
$mysqli=mysqli_connect("localhost","root","","politicalforum");
$query="SELECT query_title FROM administrator";
$query.="SELECT thread_id FROM threads";
if($mysqli->multi_query($query))
{
do
{
if($result=$mysqli->store_result())
{
while($row=$result->fetch_row())
{
printf("%s\n",$row[0]);
}
$result->free();
}
if($mysqli->more_results())
{
print("-------------------------------");
}
}while($mysql->next_result());
}
$mysqli->close();
?>
It doesnt work.. it doesnt go to the first if condition that identifies if it is a multiquery..
I have other question, ..why are multi_query() is useful..,
UPDATE:
Strict Standards: mysqli::next_result() [mysqli.next-result]: There is
no next result set. Please, call
mysqli_more_results()/mysqli::more_results() to check whether to call
this function/method in C:\xampp\htdocs\PoliticalForum2\test.php on
line 42
SOLVED:
<?php
$mysqli=mysqli_connect("localhost","root","","politicalforum");
$query="SELECT query_title FROM administrator;";
$query.="SELECT thread_id FROM threads;";
if($mysqli->multi_query($query))
{

if($result=$mysqli->store_result())
{
while($row=$result->fetch_row())
{
printf("%s<br/>",$row[0]);
}
$result->free();
}
if($mysqli->more_results())
{
print("-------------------------------<br/>");
}
else
{
echo '<br/>';
}
}while($mysqli->more_results() && $mysqli->next_result());
}
$mysqli->close();

Answer 1

You need a semicolon at the end of the first query.
$query="SELECT query_title FROM administrator;";
$query.="SELECT thread_id FROM threads";
mysqli::multi_query

Answer 2

The reason why you get this warning, is simply because you use a do...while loop that evaluates the condition after running the command block. So when there are no more results, the contents of the loop are ran one additional time, yielding that warning.
Using a while ($mysql->next_result())...do loop should fix this. (On a general note: Using post-test loops like you did is quite uncommon in database programming)
If code is poetry, I am trying to be Shakespeare!

Answer 3

You can fix it like this:
if ($res) {
do {
$mycon->next_result(); //// instead of putting it in a while, put it here
if ($result = $mycon->store_result()) {
while ($row = $result->fetch_row()) {
foreach ($row as $cell)
$flag = $cell;
}
///$result->close();
}
$sale=$sale+1;
} while ($sale > 2);
}

Answer 4

I got the answer for the same.
please find my function below.
public function executeStoredProcedureMulti($strQuery)
{
$yml = sfYaml::load(sfConfig::get('sf_config_dir').'/databases.yml');
$params = $yml['all']['doctrine']['param'];
$dsnName = $params['dsn'];
$arrDsn = explode(";",$dsnName);
$hostName = explode("=",$arrDsn[0])[1];
$schemaName = explode("=",$arrDsn[1])[1];
$this->dbconn = mysqli_connect($hostName, $params['username'], $params['password'], $schemaName);
//return if connection was created successfully
if($this->dbconn)
{
mysqli_set_charset($this->dbconn,"utf8");
//return true;
}
else
{
$this->nErrorNumber = mysqli_connect_errno();
$this->strErrorDesc = mysqli_connect_error();
return false;
}
//check if connection exists
if($this->dbconn)
{
/* close connection */
//execute the query
if($this->dbconn->multi_query($strQuery))
{
//create table array in dataset object
$dataSet = array();
do {
//store first result set
if ($result = $this->dbconn->store_result())
{
//create data table passing it the column data
$dataTable = new CDataTable($result->fetch_fields());
//parse through each row
while ($row = $result->fetch_row())
{
$dataTable->AddRow($row);
}
$result->free();
$dataSet[] = $dataTable;
}
if (!$this->dbconn->more_results()) {
break;
}
} while ($this->dbconn->next_result());
$this->dbconn->close();
//return the complete dataset
return $dataSet;
}
else//save the error to member variables
{
$this->nErrorNumber = $this->dbconn->errno;
$this->strErrorDesc = $this->dbconn->error;
}
}
return false;
}
This is working Need to create a Class CTableData. Please make one and it will work great
