私はcrmアプリケーションを持っています。リピーターコントロールをメッセージスレッドとしてバインドする方法に1つの問題があります。最初のスレッドを質問として、2 番目のスレッドをその質問の回答として。ユーザーが複数の質問をした場合、1 番目、2 番目、.. スレッドを質問として、メッセージ チャットのように...
データベースからデータを保持するために、次のストアド プロシージャを使用します。
set ANSI_NULLS ON
set QUOTED_IDENTIFIER ON
GO
ALTER PROCEDURE [dbo].[ViewMessageThreads] (@inquiry_id varchar(50))
AS
BEGIN
SET NOCOUNT ON;
select
i.body as master_body,
h.body as history_body,
q.body as question_body,
q.Created_date as question_timestamp,
a.body as answer_body,
a.Created_date as answer_timestamp,
t.Type_name as user_type
from tbl_Inquiry_History i
left join tbl_Inquiry_master h on h.Inquiry_id=i.Inquiry_id
left join tbl_Question q on q.Inquiry_id=i.Inquiry_id
left join tbl_Answer a on a.Question_id=q.Inquiry_id
left join tbl_User_master u on u.Id=i.User_id
left join tbl_Login_master l on l.Id=u.User_id
left join tbl_Type t on t.Id = l.type_id
where (i.Inquiry_id=@inquiry_id)
END
これにより、次のような結果が得られます。
master_body history_body question_body question_t.. answer_body answer_t.. user_type
__________________________________________________________________________________________
question 1 NULL question 1 2005-03-14... NULL NULL User
question 1 NULL question 2 2005-03-14... NULL NULL User
そして、リピーターのこのデザインソースを含めます：
