mysql 日期格式返回 null
我有以下 SQL 查询。它为“invoice_date”返回 NULL。
SELECT * , fk_uid AS userId, fk_ivid AS invoice_uid, (
SELECT company
FROM tbl_users
WHERE pk_uid = userId
) AS invoice_customer, (
SELECT DATE_FORMAT( '%d/%m/%y', purchased ) AS invoice_date
FROM _invoices
WHERE invoice_uid = invoice_uid
LIMIT 1
) AS invoice_date
FROM tbl_statement_items
WHERE statement_generated = '1'
AND fk_statementId = '1'
LIMIT 0 , 30
任何帮助将不胜感激。
谢谢

您颠倒了 date_format 参数顺序。
You have inverted date_format parameters order.
