4
- rename _bind_index and _column_index to _next_*
6
- change the transaction_guard interface so you can dereference it to
7
get to its transaction and the transactions take care of not
8
rolling back or committing when they already have done (as well as
9
resetting in-progress queries).
11
- turn on extended errcodes in open() and handle them in sqlite_error
13
- query::prepare() isn't being called during construction (form
14
basic_statement's constructor)
16
- add columns() to row that returns a boost::tuple of various types
17
so multple columns can be fetched at once (look in to using
18
BOOST_PP_ITERATE macro)
20
- add a rom::column() that can take a column name. This is nexessary
21
when doing a "SELECT *" and you don't know the column indicies. To
22
implement this, the first time it is called, a column-name-to-index
23
lookup would have to be built. This should be done in the query,
24
not the row. This means that the row will have to know it's query
25
(currently is copies its _handle) to be able to call column_index()
26
on it. Is this a problem?
28
- use sqlite3_db_mutex() to provide extended error information during
29
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:
33
- a macro would be simple
34
- a templated safe-calling object (passing the comman's arg types
35
as template params) may be overkill
40
- make basic_statement and database keep a shared pointer to the
41
database handle so the classes can be made copyable. The wrappers
42
around the handle (implemented in sqlite::detail) can clean them up
43
after use. This will also make the implementation of rows (to get
44
round the forced non-dependency of rows on querys) a little easier
46
- A similar wrapper should be created for statement handles,
47
making basic_statements, querys and commands copyable. Could
48
weak_ptrs to these also be used in the database's list active
51
- expand sqlite_error - perhaps use boost::system_error (see
52
boost/asio/error.hpp for an example of extending system_error)
54
- see if we can #include "sqlite.h" in to a namespace.

- move _null_t, _exec_t and _set_index_t to sqlite::detail. Only the named instantiations of these structs need be in the sqlite namespace.
8
- add immediate_transaction
9
- committing a transaction during a query (i.e., when sqlite3_step() has returned SQLITE_ROW) causes an error. To counter this:
10
- calling query.reset() before the commit fixes the issue
11
- need to check it's not fixed in latest sqlite
12
- will need to keep a list of querys that need resetting in the database :o(
