net、razor、webmatrix,使用 .cshtml 页面。
我正在使用 jQuery 打开模式表单并使用该表单将数据插入 SQL db (SQLExpress 2012)。我正在尝试通过使用以下代码来限制重复的输入,而是从网页 [object XMLHttpReques] 获取消息。
AddDiscount.cshtml 代码为:
@{
if(IsPost){
var db = Database.Open("A-LensCatFE-01SQL") ;
var CCode=UrlData[0];
var Q1 = "SELECT * FROM dbo.tblPromos WHERE CustomerCode =@0";
var ds = db.ExecuteDataSet(Q1, CCode);
if(ds.Tables.Count > 0 && ds.Tables[0].Rows.Count > 0)
{
MessageBox.Show("Duplicates");
}
else
{
var sql = "INSERT INTO dbo.tblPromos (CustomerID, CustomerCode, Discount, VAT, VATRate, iScription, SRPBasedOn)" +
"VALUES (@0, @1, @2, @3, @4, @5, @6)";
var customerid = Request["customerid"];
var customercode = Request["customercode"];
var discount = Request["discount"];
var vat = Request["vat"] == "on" ? true : false;
var vatrate = Request["vatrrate"];
var iscription = Request["iscription"];
var srpbasedon = Request["srpbasedon"];
db.Execute(sql, customerid, customercode, discount, vat, vatrate, iscription, srpbasedon);
}
}
}
需要您的帮助,非常感谢。
存储过程代码为:
创建过程 dbo.spDiscDup
@CustomerID int =NULL,
@CustomerCode nvarchar(max)=NULL,
@Discount decimal(5,2)=NULL,
@VAT bit =NULL,
@VATRate decimal (5,2)=NULL,
@iScription money=NULL,
AS
BEGIN
IF EXISTS(SELECT * FROM tblPromos WHERE CustomerCode=@CustomerCode)
("Duplicates")
ELSE
INSERT INTO dbo.tblPromos (CustomerID, CustomerCode, Discount, VAT, VATRate, iScription, SRPBasedOn)" +
"VALUES (@0, @1, @2, @3, @4, @5, @6)
结束
