Question

我想获取所选langugage的数据，但此查询获取所有数据......

ALTER PROCEDURE [dbo].[sp_GetAbout]
AS
    SELECT 
        About.[AboutID],
        Languages.Name as LangCode,
        [About].[AboutUs], [About].[AboutUs], 
        [About].[Mission], [About].[Vision], [About].[AboutPhoto],
        CASE 
           WHEN About.IsActive = 'True' 
              THEN 'Active' 
              ELSE 'Passive'
        END AS Statu
    FROM 
        [dbo].[About]
    INNER JOIN 
        Languages on About.LangCode = Languages.Code
    WHERE
        About.Statu = 'True' 
    ORDER BY
        Statu, Languages.Name

Answer 1

您应该传递语言名称的输入参数。例如

ALTER Proc [dbo].[sp_GetAbout]
   @LangName nvarchar(3) 
    as
    SELECT About.[AboutID],

         Languages.Name as LangCode

          ,[About].[AboutUs],[About].[AboutUs],[About].[Mission],[About].[Vision],[About].[AboutPhoto],


          case when About.IsActive='True' then 'Active' else 'Passive'end as Statu


      FROM [dbo].[About]
      INNER JOIN Languages on About.LangCode = Languages.Code
      Where About.Statu='True' and LangCode = @LangName Order by Statu,Languages.Name

然后使用

进行呼叫

EXEC [dbo].[sp_GetAbout] @LangName = 'ENG'

另请注意更改案例的参数类型。因为您没有提供存储语言的方式。

Answer 2

您必须在过程中添加参数。

ALTER Proc [dbo].[sp_GetAbout] @Lang nvarchar(30) AS
SELECT About.[AboutID],
       Languages.Name AS LangCode ,
       [About].[AboutUs],
       [About].[AboutUs],
       [About].[Mission],
       [About].[Vision],
       [About].[AboutPhoto],
       CASE
           WHEN About.IsActive='True' THEN 'Active'
           ELSE 'Passive'
       END AS Statu
FROM [dbo].[About]
INNER JOIN Languages ON About.LangCode = Languages.Code
WHERE About.Statu='True'
  AND LangCode = @Lang
ORDER BY Statu,
         Languages.Name

然后你应该像

那样召唤它

EXEC [dbo].[sp_GetAbout] @Lang = 'en-GB'

对于你的C＃功能

public static DataTable GetAbout()
        {
            Fonksiyon f = new Fonksiyon();
            SqlConnection mycon = f.Baglanti;
            SqlDataAdapter da = new SqlDataAdapter("sp_GetAbout", mycon);
            da.SelectCommand.CommandType = CommandType.StoredProcedure;
            da.SelectCommand.Parameters.Add("@Lang", SqlDbType.NVarChar).Value = "en-GB";
            DataTable dt = new DataTable();
            da.Fill(dt);
            da.Dispose();
            KayitSayisi = dt.Rows.Count;
            return dt;
        }

lang的存储过程
