Error while opening NAV2013 R2 database

Some times we used to get the below error while opening NAV2013 R2 database

Error :

---------------------------
Microsoft Dynamics NAV Development Environment
---------------------------
The Object table contains a Microsoft Dynamics NAV Development Environment field data type that is not compatible with the SQL Server data type:

Field: Version List
Type: Text248
SQL type: VARCHAR(80)
---------------------------
OK  
---------------------------

to resolve this error ,Simply run the below command in SQL Server

ALTER TABLE [dbo].[Object]

ALTER COLUMN [Version List] VARCHAR(248) NOT NULL

I hope this will help some one.

Thank you.
