我在这里做了三种类型的查询:
1-仅包含品牌的查询(我得到结果)
2-只包含模型的查询(我得到结果)
3-查询包含两者(我没有得到结果)
如何完成以上三项任务?

您似乎正在执行某种搜索,因此您希望得到的结果来自控制器或视图,如果像这样的条件,则执行该操作,然后执行此操作
if ($brand_val != '' )
{ //put your where query here }
if ($model_val != '' )
{ //put your where query here }
if ($brand_val != '' && $model_val != '' )
{ //put your where query here }
希望这会给出想法

用它来打印查询。
echo $ this-&gt; db-&gt; last_query();
然后尝试在phpmyadmin中执行该查询
