Question

我在使用contains（transact-SQL）返回记录时遇到了麻烦。

此查询在SQL服务器查询窗口中使用静态值

的结果

select * from archive_master where docgroupID=46 and( CONTAINS((docno,docname,accountno,accountName,tags,docyear,docmonth),'"1"')
   OR CONTAINS((docno,docname,accountno,accountName,tags,docyear,docmonth),'"*1"')
   OR CONTAINS((docno,docname,accountno,accountName,tags,docyear,docmonth),'"1*"')
   OR CONTAINS((docno,docname,accountno,accountName,tags,docyear,docmonth),'"*1*"')
   )

但是如果我把查询放到sqlcommand并用参数替换静态值，它就不会返回记录

继承我的代码：

string oconn = ConfigurationManager.ConnectionStrings["ARCHDB"].ConnectionString;
    using (SqlConnection empCon = new SqlConnection(oconn))
    {


        if (txtsearch.Text == "")
        {
            query = "select * from archive_master where docgroupID=@docgroupID";
         }
        else
        {
           query = @"select * from archive_master where docgroupID=@docgroupID and (CONTAINS((docno, docname, accountno, accountName, tags, docyear, docmonth), '""@qry""') OR CONTAINS((docno, docname, accountno, accountName, tags, docyear, docmonth), ""*@qry"")  OR CONTAINS((docno, docname, accountno, accountName, tags, docyear, docmonth), ""@qry*"")  OR CONTAINS((docno, docname, accountno, accountName, tags, docyear, docmonth), ""*@qry*""))";
        }


        using (SqlCommand emp_Cmd = new SqlCommand(query, empCon))
        {

            if (txtsearch.Text == "")
            {
                SqlParameter pdocgroupID = emp_Cmd.Parameters.Add("@docgroupID", SqlDbType.BigInt);
                pdocgroupID.Value = Request.QueryString["docgroupID"];
            }
            else
            {
                SqlParameter pdocgroupID = emp_Cmd.Parameters.Add("@docgroupID",SqlDbType.BigInt);
                SqlParameter pqry = emp_Cmd.Parameters.Add("@qry", SqlDbType.NVarChar);
                pdocgroupID.Value = Request.QueryString["docgroupID"];
                pqry.Value = txtsearch.Text;
            }



            emp_Cmd.CommandType = CommandType.Text;
            empCon.Open();

            SqlDataAdapter adpData = new SqlDataAdapter(emp_Cmd);
            DataTable dt = new DataTable();
            adpData.Fill(dt);


            GridDocgroup.DataSource = dt;
            GridDocgroup.DataBind();
            empCon.Close();




        }
    }

是我的查询字符串正确的方法吗？其中@qry和@docgroupID是参数

  query = @"select * from archive_master where docgroupID=@docgroupID and (CONTAINS((docno, docname, accountno, accountName, tags, docyear, docmonth), '""@qry""') OR CONTAINS((docno, docname, accountno, accountName, tags, docyear, docmonth), ""*@qry"")  OR CONTAINS((docno, docname, accountno, accountName, tags, docyear, docmonth), ""@qry*"")  OR CONTAINS((docno, docname, accountno, accountName, tags, docyear, docmonth), ""*@qry*""))";

作为一种解决方法，我修改了查询并在参数值

上传递了通配符

action

查询使用CONTAINS（）返回没有记录VSS asp.net
