15 | Returns true if we have an open (and working) database connection, false if it |
16 | is not (yet) open (or does not work). (Executes a simple SELECT to make sure it |
17 | works.) |
18 | |
19 | The reason this is needed is that L<DBD::Sybase>'s ping() does not work with an |
20 | active statement handle, leading to masked database errors. |
