Comment créer la base de données ELMAH SQL Server?

Comment créer la base de données ELMAH SQL Server? Je l'ai ajouté à mon projet ASP.NET MVC via NuGet et je n'ai pas le script SQL sur ma machine.

Le script DDL est lié à la page Elmah downloads . Inutile de parcourir l’arbre source.

(Pourquoi ce n'est pas livré avec le NuGet m'échappe)

J'ai trouvé le script dans le contrôle de code source: https://code.google.com/p/elmah/source/browse/src/Elmah.SqlServer/SQLServer.sql

Exécutez ce script sur la base de données que vous utilisez pour créer les structures de base de données pour Elmah.

Pour un scénario de première migration de code, j'ai trouvé le this article très utile.

Exécutez d'abord la commande Add-Migration AddElmah dans 'Package Manager Console'. Cela créera un fichier sous le dossier Migration. Ce fichier contiendra la classe AddElmah avec les fonctions Up() et Down(). Remplacé ces deux fonctions par le code ci-dessous:

public override void Up()
{
    Sql(@"CREATE TABLE [dbo].[ELMAH_Error]
        (
            [ErrorId]     UNIQUEIDENTIFIER NOT NULL,
            [Application] NVARCHAR(60)  COLLATE SQL_Latin1_General_CP1_CI_AS NOT NULL,
            [Host]        NVARCHAR(50)  COLLATE SQL_Latin1_General_CP1_CI_AS NOT NULL,
            [Type]        NVARCHAR(100) COLLATE SQL_Latin1_General_CP1_CI_AS NOT NULL,
            [Source]      NVARCHAR(60)  COLLATE SQL_Latin1_General_CP1_CI_AS NOT NULL,
            [Message]     NVARCHAR(500) COLLATE SQL_Latin1_General_CP1_CI_AS NOT NULL,
            [User]        NVARCHAR(50)  COLLATE SQL_Latin1_General_CP1_CI_AS NOT NULL,
            [StatusCode]  INT NOT NULL,
            [TimeUtc]     DATETIME NOT NULL,
            [Sequence]    INT IDENTITY(1, 1) NOT NULL,
            [AllXml]      NTEXT COLLATE SQL_Latin1_General_CP1_CI_AS NOT NULL
        ) ");

    Sql("EXEC('ALTER TABLE [dbo].[ELMAH_Error] WITH NOCHECK ADD CONSTRAINT[PK_ELMAH_Error] PRIMARY KEY([ErrorId])')");

    Sql("EXEC('ALTER TABLE [dbo].[ELMAH_Error] ADD CONSTRAINT[DF_ELMAH_Error_ErrorId] DEFAULT(NEWID()) FOR[ErrorId]')");

    Sql(@"EXEC('CREATE NONCLUSTERED INDEX [IX_ELMAH_Error_App_Time_Seq] ON [dbo].[ELMAH_Error] 
        (
            [Application]   ASC,
            [TimeUtc]       DESC,
            [Sequence]      DESC
        )')");

    Sql(@"EXEC('CREATE PROCEDURE [dbo].[ELMAH_GetErrorXml] (@Application NVARCHAR(60), @ErrorId UNIQUEIDENTIFIER) AS
            SET NOCOUNT ON
            SELECT [AllXml] FROM [ELMAH_Error] WHERE [ErrorId] = @ErrorId AND [Application] = @Application')");

    Sql(@"EXEC('CREATE PROCEDURE [dbo].[ELMAH_GetErrorsXml]
        (@Application NVARCHAR(60), @PageIndex INT = 0, @PageSize INT = 15, @TotalCount INT OUTPUT)
        AS  
            SET NOCOUNT ON 
            DECLARE @FirstTimeUTC DATETIME
            DECLARE @FirstSequence INT
            DECLARE @StartRow INT
            DECLARE @StartRowIndex INT

            SELECT @TotalCount = COUNT(1) FROM [ELMAH_Error] WHERE [Application] = @Application

            SET @StartRowIndex = @PageIndex * @PageSize + 1

            IF @StartRowIndex <= @TotalCount
            BEGIN 
                SET ROWCOUNT @StartRowIndex

                SELECT @FirstTimeUTC = [TimeUtc], @FirstSequence = [Sequence] FROM [ELMAH_Error]
                WHERE [Application] = @Application ORDER BY [TimeUtc] DESC, [Sequence] DESC 
            END
            ELSE
            BEGIN 
                SET @PageSize = 0 
            END

            SET ROWCOUNT @PageSize

            SELECT 
                errorId     = [ErrorId], 
                application = [Application],
                Host        = [Host], 
                type        = [Type],
                source      = [Source],
                message     = [Message],
                [user]      = [User],
                statusCode  = [StatusCode], 
                time        = CONVERT(VARCHAR(50), [TimeUtc], 126) + ''Z''
            FROM [ELMAH_Error] error WHERE [Application] = @Application AND [TimeUtc] <= @FirstTimeUTC
            AND [Sequence] <= @FirstSequence ORDER BY [TimeUtc] DESC, [Sequence] DESC FOR XML AUTO')");

    Sql(@"EXEC('CREATE PROCEDURE [dbo].[ELMAH_LogError] (@ErrorId UNIQUEIDENTIFIER, @Application NVARCHAR(60), @Host NVARCHAR(30),
          @Type NVARCHAR(100), @Source NVARCHAR(60), @Message NVARCHAR(500), @User NVARCHAR(50), @AllXml NTEXT, @StatusCode INT,
          @TimeUtc DATETIME) AS 

         SET NOCOUNT ON

         INSERT INTO [ELMAH_Error] ([ErrorId], [Application], [Host], [Type], [Source], [Message], [User], [AllXml], [StatusCode], [TimeUtc])
         VALUES (@ErrorId, @Application, @Host, @Type, @Source, @Message, @User, @AllXml, @StatusCode, @TimeUtc)')");
}

public override void Down()
{
    Sql("EXEC('DROP PROCEDURE [ELMAH_GetErrorXml]')");
    Sql("EXEC('DROP PROCEDURE [ELMAH_GetErrorsXml]')");
    Sql("EXEC('DROP PROCEDURE [ELMAH_LogError]')");
    Sql("Drop table ELMAH_Error");
}

Maintenant, lorsque vous exécuterez la commande Update-Database dans "Package Manager Console", la table ELMAH_Error et les procédures associées seront créées dans la base de données.
