當我向表格中插入一行時，必須在c＃中生成一個數字「Reference Number」。c＃中的字符串+數字發生器＃
該參考號碼應生成的數據被插入，並保存在表中的一列後：
我的表（dbo.Cha）的結構是：
ChaId (Primary Key) - 1
CreatedDate (Date) - 23/03/2016
ChaReferenceId (Varchar) -
最終出了將"CHA0316001"
我要添加的「表名+月/年+ 00 +的PrimaryKey」 - CHA0316001 並保存在同一個表中的列「ChaReferenceId」列中的值 - dbo.cha
SQL服務器 - 程序：
CREATE PROCEDURE [dbo].[Cha_Insert]
@ChaName varchar(50),
@PortId int,
@StateId int = NULL,
@CountryId int,
@Address varchar(50),
@PhoneNumber int,
@EmailId1 varchar(50),
@CreatedDate date = NULL,
@CreatedById int = NULL
AS
SET NOCOUNT ON
INSERT INTO [dbo].[Cha]
([ChaName] ,[PortId],[StateId],[CountryId],[Address],[PhoneNumber],[EmailId1],[CreatedDate],[CreatedById],[IsActive])
VALUES(@ChaName, @PortId, @StateId, @CountryId,@Address,@PhoneNumber,@EmailId1,GETDATE(),@CreatedById,'true')

如果我理解你的數據類型是正確的 - 那麼這可以直接在數據庫中進行（觸發爲例），或者你可以使用輸出到獲取變量值返回到您的代碼。 –
你的問題是什麼？ –
標記使用的dbms。該代碼根本不像ANSI SQL。 – jarlh
