To Whom It May Concern,
I've been working for the last few months (delayed often, but mostly the
last few weeks) on what I've been tenatively calling ODBC2. Basically
this is what I'd like to see PHP v 5 have as it's default ODBC system.
Some general notes about it:
- It will break BC. I have tried to conform and keep things the same,
but I'm not making any promises to keep BC at this time.
- It will support ODBC v 3.0 and greater only. With the needs of many DBs
to include larger typesets (like TEXT, NTEXT, IMAGE, etc) and UNICODE, I
see this as being a necessity.
Some implementation notes:
- So far my testing is being done using iODBC, unixODBC, and Windows ODBC
drivers. I have no way of checking any of the others... help on this
front would be appriciated.
Some of the features already added to it:
- Ability to control the ODBC environment handles before and after a
connection is created.
- Ability to specify a CURSOR for use in statements.
- More strongly enforced safe_mode restrictions.
- The ability to connect to data sources without being defined locally.
- A user can force the PHP system to create a new connection now.
- An attempt to make the ODBC API look more like the MySQL/PostgreSQL APIs
- An option for the user to turn on which can allow dynamic sizing of a
result set text field (currently it's static).
- Use of the default_user, default_db, and default_passwd in the php.ini.
- Hopefully more detailed error messages.
- Native support for returning results from functions, and SQL based
constructs (outside of SELECT statements).
If you have any specific functionality you would like to see, please send
it to me, and I will see what I can do about adding this in.
I would like to add this into the current PHP system, to allow users to
start playing with and testing as well. Well probably just as soon as I
finish some more of the odbc2_exec/odbc2_execute() cleanups. This code is
not optimized in any way, shape, or form. It's not even believed to work
with a lot of systems. Because of this, I would like to hear back
commentary back on any suggested recourse from those who've done this
Hopefully this will prove to be a useful change, and people will be happy
:) As always send your comments to me.
