How do I create the ELMAH SQL Server database? - asp.net-mvc

Question

How do I create the ELMAH SQL Server database? I added it to my ASP.NET MVC project through NuGet and don't have the sql script on my machine.

Answer 1

The DDL script is linked from the Elmah downloads page. No need to trawl the source tree.
(Why it's not bundled with the NuGet escapes me)

Answer 2

I found the script in source control: https://code.google.com/p/elmah/source/browse/src/Elmah.SqlServer/SQLServer.sql
Run that script on the database you are using to create the database structures for Elmah.

For a code first migration scenario, I found the this article very helpful.
First run Add-Migration AddElmah command in 'Package Manager Console'. This will create a file under Migration folder. This file will contain AddElmah class with to functions Up() and Down(). Replaced these two functions with below code:
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");
}
Now when you will execute Update-Database command in "Package Manager Console", ELMAH_Error table and associated procedures will be created in the database.

Elmah source has been moved to GitHub. The current file for SQL Server is located in the SqlErrorLog repo under the Elmah organization.
SqlErrorLog: /src/SQLServer.sql
Other database scripts can be found by searching errorlog under the Elmah GitHub organization. e.g. https://github.com/elmah?q=errorlog
