- look in to making query and command's _handle a shared_ptr, so that query
5
and command classes can be copied.

- rename _bind_index and _column_index to _next_*

- change the transaction_guard interface so you can dereference it to get to
10
its transaction and the transactions take care of not rolling back or

committing when they already have done (as well as resetting in-progress

- add columns() to row that returns a boost::tuple of various types so multple

22
- add a row::column() that can take a column name. This is nexessary when
23
doing a "SELECT *" and you don't know the column indicies. To implement
24
this, the first time it is called, a column-name-to-index lookup would have
25
to be built. This should be done in the query, not the row. This means that
26
the row will have to know it's query (currently is copies its _handle) to be
27
able to call column_index() on it. Is this a problem?

- use sqlite3_db_mutex() to provide extended error information during
30
sqlite_error construction. The general procedure would be to lock the db
31
mutex, perform some sqlite3 command, check the error code, throw an
32
sqlite_error (whilst obtaining extended error info) and then unlock the db

sqlite_error construction. The general procedure would be to lock
30
the db mutex, perform some sqlite3 command, check the error code,
31
throw an sqlite_error (whilst obtaining extended error info) and
32
then unlock the db mutex. Two options:
34
33
- a macro would be simple
35
- a templated safe-calling object (passing the comman's arg types as
36
template params) may be overkill

- make basic_statement and database keep a shared pointer to the database
42
handle so the classes can be made copyable. The wrappers around the handle
43
(implemented in sqlite::detail) can clean them up after use. This will also
44
make the implementation of rows (to get round the forced non-dependency of
45
rows on querys) a little easier to swallow.
46
- A similar wrapper should be created for statement handles, making
47
basic_statements, querys and commands copyable. Could weak_ptrs to these
48
also be used in the database's list active querys?

- expand sqlite_error - perhaps use boost::system_error (see

boost/asio/error.hpp for an example of extending system_error)
