LEFT JOIN LATERAL показывает ошибку с SELECT

Question

Я пытаюсь выполнить запрос ниже:

SELECT
tc.ID_NUMBER AS AFC_RPP_Number,
hc.BUSINESS AS Business,
hc.DIRECTOR AS Director,
tc.REASON_FOR_REVISION AS Description_of_Change
FROM alo_gg.AWS_PIM tc
left join lateral(
    select BUSINESS,DIRECTOR                
    FROM alo_ggg.tracker
    WHERE START_DATE <= tc.DATE AND  SO = tc.SO 
    ORDER BY START_DATE DESC 
    LIMIT 1
) hc;

Вышеприведенный запрос показывает ошибку:

ERROR:  syntax error at or near "SELECT"
left join lateral (SELECT BUSINESS,DIRECTOR...

Если я запускаю подзапрос отдельно, он дает мне результат, но с lateral это дает мне ошибку.

Answer 1

Вам нужно добавить ON TRUE и убрать запятую:

SELECT
tc.ID_NUMBER AS AFC_RPP_Number,
hc.BUSINESS AS Business,
hc.DIRECTOR AS Director,
tc.REASON_FOR_REVISION AS Description_of_Change
FROM alo_gg.AWS_PIM tc -- removing comma
left join lateral(
    select BUSINESS,DIRECTOR                
    FROM alo_ggg.tracker
    WHERE START_DATE <= tc.DATE AND  SO = tc.SO 
    ORDER BY START_DATE DESC 
    LIMIT 1
) hc  ON TRUE;  -- adding `ON` clause
