+ Portability notes: Some databases choose to delay preparing a query
until it is executed the first time. In this case, preparing a
syntactically wrong query succeeds, but every consecutive exec()
will fail.
+ When the database does not support named placeholders directly,
+ the placeholder can only contain characters in the range [a-zA-Z0-9_].
For SQLite, the query string can contain only one statement at a time.
If more than one statement is given, the function returns \c false.
