我在将参数传递给'IN'子句时遇到问题.我正在使用以下查询.

I am facing problem passing parameters to 'IN' clause. I am using the below query.

查询:

SELECT Topics.Topic_Id  FROM Topics 
    Where Topic_Description IN (''+ @Topics +'')    

当参数具有单个值时，此查询有效.我的参数可以用逗号分隔多个值，例如:一个"，两个"，三个"，四个".但是，只要有多个参数，查询就会失败.如何克服这个问题?请提出建议.

This query works when the parameter has single value. My parameter can have comma separated multiple values like : 'one','two','three','four'. But the query fails whenever there are multiple parameters. How to get over this ? Please suggest.

谢谢

我必须将以上内容用作存储过程的一部分.我必须将选择查询的结果放入光标，如下所示:

I have to use the above as part of a stored procedure. I have to take the result of the select query into a cursor like below:

DECLARE cur_TopicIDs CURSOR FOR SELECT Topics.Topic_Id从主题何处 Topic_Description IN(''+ @Topics +'').... etc

DECLARE cur_TopicIDs CURSOR FOR SELECT Topics.Topic_Id FROM Topics Where Topic_Description IN (''+ @Topics +'')....etc

在这种情况下，如何按照其他链接的建议使用动态sp

In this case how can I use dynamic sp as suggested in other links
