我有一个名为spGetVideosByLocation的MYSQL函数。目前我称之为:
CALL spGetVideosByLocation(location);
这基本上调用了类似这样的查询:
SELECT * FROM Videos WHERE LocationId = location;
我的问题是,当我调用函数时,有没有办法定义ORDER BY? 我如何得到这个:
CALL spGetVideosByLocation(location, "tableName", DESC);
要查询:
SELECT * FROM Videos WHERE LocationId = location ORDER BY tableName DESC;
答案 0 :(得分:0)
您使用的是哪种编程语言?假设您使用的是php,我将使用以下代码:
function spGetVideosByLocation($locationid, $order, $orderby)
{
$sql = "SELECT * FROM Videos WHERE LocationId = '$locationid' ORDER BY $order $orderby";
$result = mysql_query($sql) or die(mysql_error());
//do whatever you need to to get results
}
