How to export a SQL Server 2008 Database Diagram to another DB?

Question

I use the handy Database Diagramming tool in SQL Server 2008 for creating and managing relationships. I have exported the sourceDB to the destinationDB but the diagram does

Answer 1

This generates an import string:

SELECT
    'DECLARE @def AS VARBINARY(MAX) ; ' +
    'SELECT @def = CONVERT(VARBINARY(MAX), 0x' + CONVERT(NVARCHAR(MAX), [definition], 2) + ', 2) ;' +
    ' EXEC dbo.sp_creatediagram' +
        ' @diagramname=''' + [name] + ''',' +
        ' @version=' + CAST([version] AS NVARCHAR(MAX)) + ',' +
        ' @definition=@def'
    AS ExportQuery
FROM
    [dbo].[sysdiagrams]
WHERE
    [name] = '' -- Diagram Name

Next, you run the generated string in other DB.

As PROCEDURE:

-- =============================================
-- Author:      Eduardo Cuomo
-- Description: Export Database Diagrama to SQL Query
-- =============================================
CREATE PROCEDURE [dbo].[Sys_ExportDatabaseDiagram]
    @name SYSNAME -- Diagram Name
AS

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

SELECT
    'DECLARE @def AS VARBINARY(MAX) ; ' +
    'SELECT @def = CONVERT(VARBINARY(MAX), 0x' + CONVERT(NVARCHAR(MAX), [definition], 2) + ', 2) ; ' +
    ' EXEC dbo.sp_creatediagram' +
        ' @diagramname=''''' + [name] + ''''',' +
        ' @version=' + CAST([version] AS NVARCHAR(MAX)) + ',' +
        ' @definition=@def'
    AS ExportQuery
FROM
    [dbo].[sysdiagrams]
WHERE
    [name] = @name
