使用NOT IN子查詢進行更新時出錯

Question

我的查詢出了什麼問題，它爲什麼不執行？

UPDATE mbdb.pessoa 
SET status = 4 
WHERE id_pessoa NOT IN 
    (SELECT id_pessoa 
    FROM mbdb.pessoa mp 
    INNER JOIN mbdb.funcionario mf ON mp.cpf = mf.cpf) 

錯誤代碼：
您不能指定目標表「昂佩索阿」的更新在FROM子句

Answer 1

UPDATE mbdb.pessoa mp 
LEFT JOIN mbdb.funcionario mf 
ON mp.cpf = mf.cpf 
SET status = 4 
WHERE funcionario.cpf IS NULL 

Answer 2

MySQL不會讓你更新記錄和使用子查詢你正在嘗試使用。

您可以將您的代碼更改爲此。

UPDATE mbdb.pessoa m 
SET m.status = 4 
WHERE NOT EXISTS (SELECT 1 FROM mbdb.pessoa WHERE id_pessoa= m.id_pessoa)
