我如何编写查询以获得 3sname的type=0另一个 3stype=1和 3stype=2总共 9 name。我只输出type=0. 发誓UNION ALL。

Select forum_thread.name, forum_thread.updatedat, forum_thread.threadtype
From forum_thread, business
Where business.id = 1 AND forum_thread.threadtype=0
Order by forum_thread.threadtype, forum_thread.updatedat desc limit 3
UNION ALL

告诉我有什么问题。如果字符串相同，则为“1”，如果不同，则为未定义。我需要它是真还是假。

function slowStringComparison(givenSignature, computedSignature, cb) {
if (!givenSignature || !computedSignature || givenSignature.length !== computedSignature.length) {
    return cb(false);
}
var n = computedSignature.length;
var signaturesMatch = true;

for (var i = 0; i < n; i++) {
     signaturesMatch &= (computedSignature.charAt(i) == givenSignature.charAt(i));
}
return cb(null, signaturesMatch);}
