php - Yii Create Command 无法从 select 获取硬编码值

Question

这是我的查询

$result = Yii::app()->db->createCommand()->setFetchMode(PDO::FETCH_OBJ)
->select('t.id, "contract" AS type')
->from('test t')
->where('t.company_id=1')
->queryAll();

我收到此错误，

Column not found: 1054 Unknown column '"contract"' in 'field list'. The SQL statement executed was: SELECT `t`.`id`, `"contract"` AS `type` FROM `test` `t` WHERE t.company_id=1

Answer 1

尝试使用避免文字名称，例如:

  $result = Yii::app()->db->createCommand()->setFetchMode(PDO::FETCH_OBJ)
    ->select('t.id,  case when 1 = 1 then 'contract' end AS type')
    ->from('test t')
    ->where('t.company_id=1')
    ->queryAll();
