ColdFusion - 如何在cfscript中执行SQL"IN"子句？

Question

我如何在cfscript中构造一个IN子句？这就是我所拥有的:

var tagList = "301,302,303,304";
var q = new Query ();
q.setDatasource ("mydatasource");

var sqlStmt = "SELECT * FROM Tags WHERE tagID IN (:tagList)";

// I know the next line is not correct!
q.addParam (name="tagList", value="#tagList#", cfsqltype="??? WHAT SHOULD IT BE ???");

有没有一种简单的方法可以做到这一点,还是我需要遍历标签列表,分别添加每个标签？

Answer 1

有一个列表属性<cfqueryparam>应该支持:

q.addParam (name="tagList", value="#tagList#", cfsqltype="CF_SQL_INTEGER", list="yes");
