使用 LEFT JOIN 删除

我想根据引用第一个表的另一个表中存在的数据从表中删除，但是，当我将其作为 SELECT stetement 运行时，我有有效的代码并显示要删除的值，但是当我将其更改为删除它给了我错误，我不明白它们为什么在那里。

DELETE leadCustomer.* FROM coursework.leadCustomer LEFT JOIN coursework.flightBooking
ON leadCustomer.customerID = flightBooking.customerID
WHERE leadCustomer.customerID NOT IN (
SELECT customerID FROM (SELECT customerID, status FROM coursework.flightBooking) AS
StatusCount where status IN  ('R','H') GROUP BY customerID
)
AND leadCustomer.customerID = 8;

Error:

ERROR:  syntax error at or near "leadCustomer"
LINE 1: DELETE leadCustomer.* FROM coursework.leadCustomer LEFT JOIN...
               ^

********** Error **********

ERROR: syntax error at or near "leadCustomer"
SQL state: 42601
Character: 8

我正在使用 postgres

样本。删除表“A”中的记录是否表“H”中没有记录

DELETE A FROM ARTICULO_ALMACEN A
LEFT JOIN HISTORICO_UNION H
ON A.COD_ARTICULO = H.COD_ARTICULO
AND A.COD_ALMACEN = H.COD_ARTICULO_ALMACEN
AND A.TPROPIEDAD1 = H.PROPIEDAD1
AND A.TPROPIEDAD2 = H.PROPIEDAD2
AND A.TPROPIEDAD3 = H.PROPIEDAD3
WHERE H.COD_ARTICULO IS NULL
