Cannot insert the value null into column ‘diagram_id’, table dbo.sysdiagrams

Error Condition: Cannot insert the value null into column ‘diagram_id’, table dbo.sysdiagrams

Problem: This sometimes occurs when a SQL Server database is ported from one version to another (such as 2000 to 2005 or 2005 to 2008) or possibly also when using the SSMS for a newer version of SQL Server against and older database.

Fix: Drop and recreated dbo.sysdiagrams making the column diagram_id an identity column. 

use [mydatabase]
GO
DROP TABLE [dbo].[sysdiagrams]
GO

CREATE TABLE [dbo].[sysdiagrams]

(   [name] [nvarchar](128) NOT NULL,
    [principal_id] [int] NOT NULL,
    [diagram_id] [int] identity(1,1) NOT NULL,
    [version] [int] NULL,
    [definition] [varbinary](max) NULL
)
GO

NOTE: If you want to preserve the diagrams, then rename the table and create a
new one, then SELECT – INTO to copy the data into the new table.

Problem: Unable to run a query through a linked server SQL Server 2008 R2. This problem occurs with a non-sysadmin account.

Error Message:

Msg 7416, Level 16, State 2, Line 1
Access to the remote server is denied because no login-mapping exists. (Microsoft SQL Server, Error: 7416)

Cause: When creating a linked server with the parameter @provstr and you use a local SQL Server non-admin or non-Windows account, you have to add the parameter “User Name”   into the @provstr

Note: Also do not use ‘SQL Server’ (note space) as product name, as you cannot specify a provider or any properties for product ‘SQL Server’

Resolution : Add “User ID=remoteLogin” into the provider string on your linked server

EXEC master.dbo.sp_addlinkedserver @server = N’LinkServerName’, @provider=N’SQLNCLI’,@srvproduct = ‘SQLSERVER’, @provstr=N’SERVER=serverNameInstanceName;User ID=remoteLogin’

EXEC master.dbo.sp_addlinkedsrvlogin @rmtsrvname = N’LinkServerName’, @locallogin = ‘localLogin’ , @useself = N’False’, @rmtuser = N’remoteLogin’, @rmtpassword = N’*****’

Check:

SELECT * FROM OPENQUERY ([LinkServerName], ‘SELECT * FROM sysobjects’)
