One of the features I would like to see in our tools for SQL Server is a T-SQL language service. This would give customers features like intellisense, text completion, refactoring (e.g. renaming a table everywhere at once), error highlighting (as in Word’s red squiggly underlining), and host of other features that C# and Visual Basic have in Visual Studio 2005. Unfortunately, implementing a language service for T-SQL requires solving some difficult problems.
