Wrong Syntax for Order Column Names

[SDJeff]

I am using here MSSQL and i got an error if columns are configured because of the order by Clause.

SQLSTATE[HY000]: General error: 20018 Incorrect syntax near '`'

I think it will be a problem with the syntax depending of the quotes because the column name is wrapped in simple quotes like: order by `Gruppe` desc

The correct syntax should be

ORDER BY 'Gruppe' DESC
