這是一個有效的SQLite查詢

Question

我：

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

的查詢，但我需要的correct_incorrect列也考慮到了「1 *」

這將是一個有效的辦法考慮它？

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

我會測試它，但「1 *」的可能性很少，需要幾個小時的測試。所以我想確保我不只是在浪費時間。

Answer 1

嘗試通過使用IN

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

Answer 2

據我所知，應該是這樣的：

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

Answer 3

由於許多querys這裏給出，但我認爲「1」會來in'1 *'

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

這個查詢呢？
