200文字を超える文字列をparam経由でストアドプロシージャに渡す方法

Question

私のコードでは、私のデータテーブルに存在するすべての記事の合計要求を作成する必要があります。すべてのアーティクルIDを連結します'a1、a2、a3'のような1つの文字列で、これは動作するはずです。

しかし私は大きなIDと約150の記事を持っているので、ストアドプロシージャに渡そうとする文字列は約1300文字です。これはストアドプロシージャに行くときに200文字で切り捨てられます。

この文字列を切り捨てるためにSQL Serverを使用せずに大きな文字列をストアドプロシージャに渡す方法はありますか？

私はここでC＃コードまたはSQLストアドプロシージャを書くことができます。ここで

がストアドプロシージャである：私は、SQLのパラメータを追加して、私のメソッド内p.Size = 200;を持っていた

Answer 1

私はSean Langeのコメントに同意し、文字列を送信してSQLで解析する代わりに、テーブル値のパラメータを使用することをお勧めします
これを行うには、SQL Serverでユーザー定義のテーブルタイプを作成する必要があります。

CREATE TYPE dbo.ArticleIds as table 
(
    Id varchar(10) -- should be the same as Code_article definition! 
) 
GO 

して、ADO.NETを使ってC＃からパラメータを大切にテーブルとストアドプロシージャを実行するには

ALTER PROCEDURE [dbo].[GetChargePetrin] 
-- Add the parameters for the stored procedure here 
    @articlesList dbo.ArticleIds readonly -- Must be readonly! 
AS 

BEGIN 
    -- SET NOCOUNT ON added to prevent extra result sets from 
    -- interfering with SELECT statements. 
    SET NOCOUNT ON; 

     SELECT 
     CAST(SUM(CAST(Qa01 AS INT) /CAST(a.CO_UQB_PET AS INT)) AS varchar) as 'qa1', 
     CAST(SUM(CAST(Qa02 AS INT) /CAST(a.CO_UQB_PET AS INT)) AS varchar) as 'qa2', 
     -- ... more of the same 
     CAST(SUM(CAST(Qa60 AS INT) /CAST(a.CO_UQB_PET AS INT)) AS varchar) as 'qa60' 
     FROM [PDP_TTP].[dbo].[PDP] p 
     INNER JOIN [PDP_TTP].[dbo].[Articles] a ON a.Division=p.Division AND a.Code_article=p.Code_article 
     INNER JOIN @articlesList al ON a.Code_article = al.Id 
     WHERE CAST(a.CO_UQB_PET AS INT) > 0 

END 

としてそれを使用し、必要にタイプSqlDbType.Structuredのパラメータを送信し、値としてDataTableを渡します。

Answer 2

、私はp.Size = 8000;にそれを変更しなければならなかったし、それが働いています。

ありがとうございました！
