我有一个查询来选择所有未投票的提案ProProposalBundle:Proposal\Vote。 "not_voted"中可能存在v.decision值，或者可能不存在NOT EXIST值。这就是我使用SELECT p
FROM ProProposalBundle:Proposal p
INNER JOIN ProProposalBundle:Proposal\Vote v
WITH v.proposal = p
AND (v.decision = 'not_voted' OR NOT EXISTS (SELECT v FROM v WHERE v.user = {$user}))
WHERE p.community = {$community}
的原因。
[Semantical Error] line 0, col 181 near 'v WHERE v.user': Error: Class 'v' is not defined.
但它给我一个错误：
NOT EXISTS并且它与v部分有关，其中... NOT EXISTS (SELECT v FROM ProProposalBundle:Proposal\Vote v WHERE v.user = {$user}))
在理论上定义之前。我也尝试过：
[Semantical Error] line 0, col 220 near 'v WHERE v.user': Error: 'v' is already defined.
但现在我得到了：
{{1}}
知道我做错了什么？
答案 0 :(得分：0)
试
NOT EXISTS (SELECT * FROM ProProposalBundle:Proposal\Vote v WHERE v.user = {$user}))
