java - 这是一个有效的 SQLite 查询吗

Question

我有：

String sqlite = "SELECT count(_id) AS _lCount FROM answers WHERE phase = 3 and correct_incorrect='1'

作为查询，但我需要正确的不正确列也考虑到“1 *”

这是一种有效的解释方法吗？

String sqlite = "SELECT count(_id) AS _lCount FROM answers WHERE phase = 3 and correct_incorrect='1'or'1*'

我会测试它，但“1*”的可能性很少，需要几个小时的测试。所以我想确保我不只是在浪费时间。

尝试使用IN

String sqlite = "SELECT count(_id) AS _lCount FROM answers WHERE phase = 3 and correct_incorrect IN ('1','1*')"

score 2 · Accepted Answer

据我所知，它应该是这样的：

String sqlite = "SELECT count(_id) AS _lCount FROM answers WHERE phase = 3 and (correct_incorrect='1' or correct_incorrect = '1*')

score 1 · Accepted Answer

由于这里给出了许多查询，但我认为 '1' 会出现在 '1*' 中

String sqlite = "SELECT count(_id) AS _lCount FROM answers WHERE phase = 3 and correct_incorrect like '1*'";

这个查询呢？
