Thanks for this nice question which I answered in the good way only because I knew the history of the imbrication between Access and SQL Server.
Thanks also for the valuable information provided by every one ( it is always to read Hugo's one , always long but interesting and informative ).
I have worked with Oracle ( 6 version long time ago 2003 maybe ) but I did not like the SQL used by it. This QOT remembered me the difficulties I had to modify queries in the application I had to update.
Have a nice week-end for all.
