php - mysql query yii not getting value -



php - mysql query yii not getting value -

i have issue gettin' value query:

public static function sa() { $resul = yii::app()->db->createcommand()->select('max(id)')->from('yii_availability')->execute(); $got = mysql_query($result); $res = $got['max(id)'] + 1; $rs='sa'.$res; homecoming "{$rs}"; }

it homecoming sa1, want lastly id , after plus 1 in case have next autoincremental id id column.

for example: creating new registry field sa0000005. number calculated getting lastly autoincremental value plus 1.

thanks valuable help

$resul = yii::app()->db->createcommand()->select('max(id)')->from('yii_availability')->execute(); $got = mysql_query($result); // doing here

apart typos, that's not how supposed utilize query builder. have read the documentation on query builder?

the probable reason why sa1, because $got['max(id)'] look null. add together 1 that. want like this.

// returns false on no-result, max('id') otherwise yii::app()->db->createcommand()->select('max(id)')->from('yii_availability')->queryscalar();
