php - mysql php 语句

Question

我有这些陈述。

"SELECT * FROM PLACE.country WHERE Number='" .mysql_real_escape_string($num) ."'";<br>
"SELECT * FROM PLACE.country WHERE StreetNumber='" .mysql_real_escape_string($num) ."'";<br>
"SELECT * FROM PLACE.country WHERE PostNumber='" .mysql_real_escape_string($num) ."'";

如何将它们合并到一个语句中？

谢谢

The SQL AND & OR statement .

这是一个示例(使用 SQL):

SELECT * FROM `some_table` WHERE `a`='1' AND `b`='2' AND `c`='3'

SELECT * FROM `some_table` WHERE `a`='1' OR `b`='2' OR `c`='3'
