我想內連接多個列,但導致在哪裏條件無效列。 查詢:其中條件失敗的多個內部連接sql
select t_contract,t_complete,t_zone_name, t_street_name, t_vrm, t_make, t_model,t_colour,t_date_finally_settled,t_cancelled,t_offence_code,
t_date_time_issued, CONVERT(VARCHAR, t_date_time_issued, 103) as date_issued, CONVERT(VARCHAR, t_date_time_issued, 108) AS time_issued, te_event, lhr.*

LEFT OUTER JOIN

SELECT DISTINCT thr.thr_system_ref, hr.hr_description AS latest_on_hold_reason

INNER JOIN dbo.ticket_hold_record thr
ON (t.t_number=thr.thr_system_ref)
INNER JOIN

SELECT mthr.thr_system_ref, MAX(mthr.thr_on_hold_date) AS m_thr_on_hold_date

Inner JOIN
ticket_events te
ON (t.t_number = te.te_system_ref)
where thr.thr_hold_type = '2420135'
and convert (datetime,te_date,101) between convert(datetime,'2015/11/01',101)
and convert (datetime,'2015/11/25',101)
錯誤: 列前綴「THR」不與在查詢中使用表名或別名相匹配。
當時只需刪除一個條件,和看看它何時執行沒有錯誤。然後你可以糾正它。 (提示:where thr.thr_hold_type ='2420135'...移到子查詢中。) – jarlh
從外部選擇中不可見thr表。您應該將條件放在從此表中選擇的查詢 – Aaron
Jarlh只有一個條件,並且該列來自多個內部聯接,並且我使用了最新的lhr別名但仍然失敗。 –
