在MySQL的LEFT JOIN中使用DISTINCT

Question

這是我的查詢

SELECT agent.agtname AS `agent_name`, agent.id as `agent_id`, applicant.* 
FROM `applicant` 
LEFT JOIN agent ON agent.id = applicant.agtid 
WHERE agent.branchid ='".$branch_id."' 
AND applicant.appt_status LIKE '%SENT%' 
AND DATE(`modifiedon`) = CURDATE()

我不需要重復的agent_name和agent_id。

提前致謝

讓我們嘗試一下。 它會工作...

SELECT agent.agtname as agent_name,agent.id as agent_id, applicant.* FROM applicant LEFT JOIN agent ON agent.id = applicant.agtid WHERE agent.branchid ='".$branch_id."' AND applicant.appt_status LIKE '%SENT%' AND DATE(modifiedon) = CURDATE() GROUP BY agent.agtname
