It is said that we may work on SQL Server connecting to Object Explorer by using the SQL Management Studio tool (SSMS) of an older version. It is true up to a point, but there is a risk of getting some unexpected errors, for instance, we might get this error while working connected to SQL Server 2012 Object Explorer by using SQL Server 2005 SSMS.
More specifically, the error is raised because superior versions support more features, which means that each feature is likely to have one folder on the Object Explorer. Put differently, there is a bigger number of folders to display in SQL Server 2012 than SQL Server 2005 whose Object Explorer cannot display more because the max array index is outside the bounds that this supports. Ideally, it is highly advisable to always use the latest SSMS to connect to older versions (but not vice versa). As simple as water. That is all for now, let me know any remarks you may have. Thanks for reading.
