对于我的一个查询列,我想要一个CASE
语句。
情景是
如果我的列名ltt.f_complete task_completed
值为0
,那么值shd为NO
,如果1
则为YES
。
我尝试过以下但是得到了
ORA-00905:缺少关键字
这是查询
SELECT flv.property_name project_name, flv.building building_name,
flv.flat_no unit_no,
ldet.customer_fname
|| ' '
|| ldet.customer_mname
|| ' '
|| ldet.customer_lname customer_name,
la.booking_date holding_date, ltt.start_date task_date,
tid.task_desc task_type, fol.next_follow_up_date,
ltt.remarks task_comment, ltt.f_complete task_completed,
CASE TASK_VALUE WHEN '0' THEN 'NO'
WHEN '1' THEN 'YES',
act.act_desc activity_description, flv.follow_type followup_type,
fol.remarks followup_comment,
fol.next_follow_up_date next_followup_date,
actt.act_desc next_todo_activity
FROM xxcus.xxacl_pn_leases_all la,
(SELECT *
FROM xxcus.xxacl_pn_lease_det
WHERE sr_no = 1) ldet,
xxcus.xxacl_pn_lease_task_trl ltt,
xxcus.xxacl_pn_customer_followup fol,
xxacl_pn_flat_det_v flv,
xxcus.xxacl_pn_hold_task_v tid,
xxcus.xxacl_pn_hold_act_v act,
xxcus.xxacl_pn_followup_type_v flv,
xxcus.xxacl_pn_hold_act_v actt
WHERE la.booking_no = ltt.draft_form_no(+)
AND ltt.draft_form_no = fol.booking_no(+)
AND ltt.task_id = fol.task_id(+)
AND ltt.task_sr_no = fol.task_sr_no(+)
AND la.delete_flag = 'N'
AND la.booking_no = ldet.booking_no
AND fol.followup_date = TO_DATE (SYSDATE - 1)
AND la.flat_id = flv.flat_id
AND ltt.task_id = tid.task_id
AND fol.activity_id = act.act_id
AND fol.followup_type_id = flv.follow_type_id
AND fol.next_activity_id = actt.act_id
请提出错误的建议

答案 0 :(得分:2)
您缺少的关键字是END
。它应该是这样的:
CASE TASK_VALUE WHEN '0' THEN 'NO'
WHEN '1' THEN 'YES' END
