postgresql - Dovecot SQL 查询错误 - 为什么？

Question

SELECT CONCAT('maildir:/var/vmail/',maildir) AS mail,
       5000 AS uid, 
       5000 AS gid 
FROM mailbox 
INNER JOIN domain 
WHERE username = 'test@example.com'
  AND mailbox.active = '1'
  AND domain.active = '1'   

这个查询有什么问题？Postgresql 说：

'ERROR:  syntax error at or near "WHERE" 
LINE 1: ...S uid, 5000 AS gid FROM mailbox INNER JOIN domain WHERE user...'

Answer 1

尝试这个

SELECT CONCAT('maildir:/var/vmail/',maildir) AS mail,
       5000 AS uid,
       5000 AS gid
FROM mailbox
INNER JOIN DOMAIN on
  username = 'test@example.com'
  AND mailbox.active = '1'
  AND DOMAIN.active = '1'
