Thanks. Appreciate the quick and comprehensive response. Can you explain this a bit more: "It is possible to specify them in the default Regular compatibility mode "
Just curious, since the settings can't persist... what would happen if, in default mode, I created MyTable and also "mytable" and then later, connected with CASE_INSENSITIVE_IDENTIFIERS and queried SELECT * FROM MYTABLE ?
