Question

我需要更新＆＃34;付款＆＃34;表＆＃34; payment_status＆＃34;列到＆＃39; 1＆＃39;在结果中跟随SELECT查询但在单个查询中。请帮帮我。

SELECT * FROM payments p
INNER JOIN invoice i
ON i.invoice_number = p.invoiceGRN_id
WHERE i.invoice_status = '2' AND i.payment_type = 'Credit'

Answer 1

您可以使用UPDATE

进行INNER JOIN

UPDATE payments p
INNER JOIN invoice i
ON i.invoice_number = p.invoiceGRN_id
SET p.payment_status = 1
WHERE i.invoice_status = '2' AND i.payment_type = 'Credit'

或者你可以做这样的事情（效率较低，但更直接地回答你的问题）：

UPDATE payments 
SET payment_status = 1 
WHERE id IN (
    SELECT p.id FROM payments p
    INNER JOIN invoice i
    ON i.invoice_number = p.invoiceGRN_id
    WHERE i.invoice_status = '2' AND i.payment_type = 'Credit'
)

Answer 2

这应该可以解决问题：

UPDATE payments SET payment_status = 1 WHERE payment_ID in (
  SELECT payment_ID FROM payments p
  INNER JOIN invoice i
  ON i.invoice_number = p.invoiceGRN_id
  WHERE i.invoice_status = '2' AND i.payment_type = 'Credit')

更新从同一Query中的SELECT检索的结果
