php - 在查询中设置字段的条件

Question

我有一个sql查询:

$cond = "";
    if($cid >0 )
    {
        $quali = $this->getCandidatesQualification($cid);

        $cond = "WHERE emp_qualification LIKE '%$quali%'";
    }

    $sql = "SELECT
            emp_job_id,emp_job_profie,emp_qualification,emp_experience
        FROM
            tbl_emp_data
            $cond
        ORDER BY job_add_date DESC LIMIT 0,10   
    ";
    $res = $this->db->returnArrayOfObject($sql,$pgin = 'no', $odr='no');

现在我想要的是如果 emp_qualification字段等于 any_graduate我想为候选人选择所有职位，即使他的资格是 BA .

Answer 1

因此将 WHERE 子句修改为

WHERE emp_qualification LIKE '%$quali%' 
OR emp_qualification = 'any_graduate'
