Question

无法弄清楚这个postgresql错误正在讨论什么。

PGError: ERROR:  syntax error at or near "NULL"
LINE 1: ...at` < '2011-01-18 21:52:21.607956' OR `checked_at` IS NULL) 
                                                                 ^
: SELECT * FROM "accounts" WHERE (`checked_at` < '2011-01-18 21:52:21.607956' OR `checked_at` IS NULL)

任何想法可能是什么？

Answer 1

反击是你的问题。

SELECT * FROM accounts WHERE (checked_at < '2011-01-18 21:52:21.607956' OR checked_at IS NULL)

Answer 2

试试这个：

SELECT * FROM accounts WHERE (checked_at < '2011-01-18 21:52:21.607956' OR checked_at IS NULL)

PGError：错误：语法错误处于或接近“NULL”
