SQL Server CLR存储过程json参数

我遇到了一个场景,我想将大量数据传递给存储过程以生成一些动态SQL。

我要传递的数据存储在这个json/c类对象中,我在ASP.NET MVC Web项目中使用该对象。

[
 {
  "code":"ABC123",
  "Count": "12998",
  "Params":
  [
    {"name": "Recent", "value": "0-12m"},
    {"name": "Orders", "value": "1"}
  ]
 },
 {
  "code":"ABC124",
  "Count": "13998",
  "Params":
  [
   {"name": "Recent", "value": "0-12m"},
   {"name": "Orders", "value": "2"}
  ]
 },
 {
  "code":"ABC125",
  "Count": "7998",
  "Params":
  [
   {"name": "Recent", "value": "0-12m"},
   {"name": "Orders", "value": "3"}
  ]
 }
]
.....

然后使用这个文本参数转换回一个JSON对象,我在一个动作过滤器中使用这个参数将它转换成一个对象。

public class ObjectFilter : ActionFilterAttribute
{

    public string Param { get; set; }

    public Type RootType { get; set; }

    public override void OnActionExecuting(ActionExecutingContext filterContext)
    {

        if ((filterContext.HttpContext.Request.ContentType ?? string.Empty).Contains("application/json"))
        {

            object o =

            new DataContractJsonSerializer(RootType).ReadObject(filterContext.HttpContext.Request.InputStream);
            filterContext.HttpContext.Request.InputStream.Seek(0, SeekOrigin.Begin); // Rewind InputStream for other filters

            filterContext.ActionParameters[Param] = o;

        }

        else
        {

            var xmlRoot = XElement.Load(new StreamReader(filterContext.HttpContext.Request.InputStream,

            filterContext.HttpContext.Request.ContentEncoding));

            object o = new XmlSerializer(RootType).Deserialize(xmlRoot.CreateReader());

            filterContext.ActionParameters[Param] = o;

        }

    }

}

然后在clr存储过程中使用c等创建SQL语句,如:

UPDATE [Sample]
SET [Field] =
CASE
WHEN [Recent] = "0-12m" AND [Orders] = "1" THEN "ABC123"
WHEN [Recent] = "0-12m" AND [Orders] = "2" THEN "ABC124"
WHEN [Recent] = "0-12m" AND [Orders] = "3" THEN "ABC125"
...

这有可能吗?有人做过这样的事吗?我看到过一些关于使用XML参数的文章,但是没有一篇使用varchar参数的文章使用反序列化(?)杰森。
