java.sql.SQLException: [Microsoft][SQLServer JDBC Driver]Unexpected token type: ERROR

我的javaBean代码如下：
package chdetailPac;
import java.sql.*;
import DB.connection;
import java.lang.*;
public class getDetail
{
connection con;
public getDetail()
{
con=new connection();

}
public ResultSet getDetailInfo(String strType)
{
strType= "select insInfo.* from insInfo ,ins,minor where insInfo.insName=ins.insName and ins.ID=minor.ID and minor.ID= "+strType+ " ";
return con.executeQuery(strType);
}
}
jsp代码：
<%
String id=new String(request.getParameter( "id ").getBytes( "ISO-8859-1 "), "gb2312 ");
ResultSet rs=getDetail.getDetailInfo(id);
rs.next();
%>
在运行过程中出现了错误：
java.sql.SQLException: [Microsoft][SQLServer JDBC Driver]Unexpected token type: ERROR

请各位高手帮帮忙，以前我在ACCESS数据库中就可以运行，但转到SQL server就出现了问题，我运行其它的SQL语句都可以 ,应该不是驱动的问题了。

------解决方法--------------------------------------------------------
你参数的名字和你的sql语句的变量同名了,能不错吗?
把参数换个名字.
