MySql PHP组合选择查询1

Question

查询1

SELECT * FROM `student_1` WHERE location like '%php%'

查询2

SELECT * FROM `student_4` WHERE keyskill like '%php%'

我想将这两个表合并为一个代码和结果

Answer 1

使用UNION：

SELECT * FROM student_1 WHERE location like '%php%'
UNION
SELECT * FROM student_4 WHERE keyskill like '%php%'

只要两个表中的列匹配

Answer 2

尝试这样的事情

SELECT  (
    SELECT *
    FROM student_1
    ) where condition,
    (
    SELECT *
    FROM student_4
    ) where condition
)
