Daniel John Debrunner commented on DERBY-2243:
----------------------------------------------

MySQL's return value should have no impact on Derby, it's if Derby supports 
these features only.

Also, please be careful looking at MySQL code, bringing MySQL GPL code into 
Derby's codebase would not be acceptable.

Obviously in this case a return true/false is not an issue, but demonstrated 
access to a piece of work is enough for copyright infringements.

E.g. if someone says I looked at MySQL code to see how X was done and then 
implemented the same functionality in Derby in a similar manner that could be 
enough to pollute the Derby code base with GPL.

> DatabaseMetaData.supportsANSI92EntryLevelSQL() returns false for embedded, 
> true for client driver

> Since this method is returning the support level of SQL it must be consistent

> Probably need some investigation as to which is correct, most likely 'true'.
