Logs error information in the ErrorLog table in SQL Server

This post describes how to logs error details using stored procedure. 

Step 1:first create error log table to store error information. 

CREATE TABLE [dbo].[ErrorLog](
    [ErrorLogID] [int] IDENTITY(1,1) NOT NULL,
    [ErrorTime] [datetime] NOT NULL,
    [UserName] [sysname] NOT NULL,
    [ErrorNumber] [int] NOT NULL,
    [ErrorSeverity] [int] NULL,
    [ErrorState] [int] NULL,
    [ErrorProcedure] [nvarchar](126) NULL,
    [ErrorLine] [int] NULL,
    [ErrorMessage] [nvarchar](4000) NOT NULL);

Step 2: Create stored procedure to insert error info.

ALTER PROCEDURE [dbo].[uspLogError]
    @ErrorLogID [int] = 0 OUTPUT
AS                             
BEGIN
    SET NOCOUNT ON;

   SET @ErrorLogID = 0;

    BEGIN TRY
      IF ERROR_NUMBER() IS NULL
            RETURN;

       IF XACT_STATE() = -1
        BEGIN
            PRINT 'Cannot log error since the current transaction is in an uncommittable state. '
                + 'Rollback the transaction before executing uspLogError in order to successfully log error information.';
            RETURN;
        END

        INSERT [dbo].[ErrorLog]
            (
            [UserName],
            [ErrorNumber],
            [ErrorSeverity],
            [ErrorState],
            [ErrorProcedure],
            [ErrorLine],
            [ErrorMessage]
            )
        VALUES
            (
            CONVERT(sysname, CURRENT_USER),
            ERROR_NUMBER(),
            ERROR_SEVERITY(),
            ERROR_STATE(),
            ERROR_PROCEDURE(),
            ERROR_LINE(),
            ERROR_MESSAGE()
            );

            SET @ErrorLogID = @@IDENTITY;
    END TRY
    BEGIN CATCH
        PRINT 'An error occurred in stored procedure uspLogError: ';
        EXECUTE [dbo].[uspPrintError];
        RETURN -1;
    END CATCH
END;
