mssql_free_result in Yii

How can I use mssql_free_result during executions of CDbCommand queries?

example of 300000 records and 128MB memory limit in php.ini:




$count=$connection->createCommand('SELECT COUNT(CP) FROM Imetec_Totale_Manuale')->queryScalar();

		

for($i=10000;$i<=$count;$i+=10000)

{

	echo $i."\n";

	$command=$connection->createCommand('SELECT TOP 10000 * FROM Imetec_Totale_Manuale WHERE CP NOT IN (SELECT TOP '.$i.' CP from Imetec_Totale_Manuale ORDER BY CP)');

	$data=$command->queryAll();

}

returns exception of memory limit

doing the same with the same php.ini but with mssql




$server='10.10.10.124';

$link=mssql_connect($server, 'sa', 'admwindows');

$dbn='imetec';

mssql_select_db($dbn);


//conto i record totali

$sql="SELECT COUNT(CP) AS ROWS FROM Imetec_Totale_Manuale" ;

$count=mssql_query($sql,$link);


for($i=10000;$i<=mssql_result($count,0,'ROWS');$i+=10000)

{

	$sql='SELECT TOP 10000 * FROM Imetec_Totale_Manuale WHERE CP NOT IN (SELECT TOP '.$i.' CP from Imetec_Totale_Manuale ORDER BY CP)';

	$query=mssql_query($sql,$link);

	echo mssql_num_rows($query), PHP_EOL;

	mssql_free_result($query);

}

works. please note




mssql_free_result($query);

how this technoque can be achieved with Yii?

See here under Fetching Query Results. You should be able to avoid memory exception using this feature.

// Oh I see. Not sure how to get query id :confused:
