php - 在 MySQL 语句中返回\'

Question

我将数据存储在 MySQL 中，如下所示:

q1
People\'s
People\'s
People\'s

我正在尝试编写一个 MySQL 语句来返回这些的计数，但它给我带来了一个问题，我已经尝试了以下所有但无济于事:

SELECT * AS Total,
(SELECT COUNT(q1) FROM results WHERE q1 = 'People\'s') AS Count_Q1
FROM results

SELECT * AS Total,
(SELECT COUNT(q1) FROM results WHERE q1 = 'People'\'s')
FROM results

SELECT * AS Total,
(SELECT COUNT(q1) FROM results WHERE q1 = 'People''\'s')
FROM results

谁能发现我哪里出错了？

Answer 1

应该是:

SELECT *,
(SELECT COUNT(q1) FROM results WHERE q1 = 'People\\\'s') AS Total
FROM results

这SQL Fiddle演示表明它确实有效。
