选择值等于1的所有值？

Question

这是仅选择“1”值的记录的最佳方法吗？我无法使它有效：/

$results = mysqli_query($connecDB,"SELECT * FROM codes WHERE php = 1 AND java = 1 AND ruby = 1 ORDER BY id ASC");

+------+----------------+---------+--------+--------+
| ID   | CODES          |   PHP   |  RUBY  |  JAVA  |
+------+----------------+---------+--------+--------+
| 1    | ford           |    1    |    0   |    0   |
+------+----------------+---------+--------+--------+
| 2    | seat           |    1    |    1   |    1   |
+------+----------------+---------+--------+--------+
| 3    | fiat           |    1    |    1   |    0   |
+------+----------------+---------+--------+--------+
| 4    | toyota         |    1    |    0   |    0   |
+------+----------------+---------+--------+--------+
| 5    | chevrolete     |    1    |    0   |    1   |
+------+----------------+---------+--------+--------+

Answer 1

如果您的列不是int，那么您的查询将无效，因此请在值周围包围引号并尝试

$results = mysqli_query($connecDB,"SELECT * FROM codes 
           WHERE php = '1' AND java = '1' AND ruby = '1' ORDER BY id ASC");

Answer 2

SELECT codes FROM table_name WHERE php = 1 AND java = 1

可以使用AND / Or作为pr required来连接条件
