I spend a lot of my time in SQL Server Management Studio. I rarely ever run tables anymore from Object Desingner and run most of my data conversions directly in T-SQL.
Why? Because it is so much faster, I can script things, save and restore scripts, share accross customers etc.
One of the pain points of working with SQL Server Queries has Always been the full companyname in front of the real table name. For this reason Intellisense was more or less useless for NAV databases.
This is fixed in SSMS 2016!
When you type
select * from Custom
SQL Server Management Studio will show this
How cool is that!
