SELECT WHERE IN使用文本字符串查询

Question

我已经看了一下，尝试了一些事情，但我似乎无法让这个工作......有人可以帮忙吗？

$typeall = " ('House','Condo','Loft','Townhouse','Land')";

$rs = mysql_query("SELECT * FROM 'houses' WHERE and category IN " .$typeall); 

不起作用

但如果我输入

$rs = mysql_query("SELECT * FROM 'houses' WHERE and category IN ('House','Condo','Loft','Townhouse','Land')"); 

它完美无缺，为什么？

感谢。

Answer 1

您应该删除and：

WHERE and category IN ...

分为：

WHERE category IN ...

Answer 2

试试这个：

$typeall = "'House','Condo','Loft','Townhouse','Land'";

$rs = mysql_query("SELECT * FROM 'houses' WHERE and category IN (".$typeall.")");

可能是变量$ typeall在括号中不起作用。

Answer 3

不要引用表名，并删除额外的and：

$typeall = " ('House','Condo','Loft','Townhouse','Land')";
$rs = mysql_query("SELECT * FROM houses WHERE category IN " .$typeall);
