这是一个有效的SQLite查询

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correct_incorrect列才能考虑“1 *”

这是解决问题的有效方法吗？

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

我会测试它，但是“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。

Answer 1

使用IN

尝试

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

Answer 2

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*')

Answer 3

这里给出了很多查询，但我认为'1'会出现'1 *'

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

这个查询怎么样？
