You should not have any problems with ODBC on Windows regarding licensing, I imagine.
After all you just need to code against the Win32 ODBC API. You don't need to consider the real driver you are talking with. -- Paulo On 10.11.2011 18:54, Steve Teale wrote:
I have pushed a first cut of the native MySQL driver to https://github.com/britseye The documentation can be seen at britseyeview.com/software/mysqln/ I'm now investigating ODBC. That should be a fairly quick exercise, since I have already done ODBCD once, and I'm just doing a sketch at this point. I expect my conclusion to be that an almost identical interface is feasible. The licensing situation for ODBC on Linux appears to be OK. I can't speak for Windows - any thoughts? My primary target for an ODBC implementation is MS SQL Server. That could be done using the TDS protocol, but since FreeTDS have already been there and is LGPL, and we only need to link, I don't really want to go there. I can see from Piotr's work on PostgreSGL that an almost identical interface is possible for that too. The license there looks friendly too, but again comments please. SQLite is a bit different by its nature, but I think that it can closely fit the pattern too - no license problems there I think. I will write up a description of the interface I'm talking about in the next few days. This is what I see as the mid level interface, a set of modules - etc.mysql, etc.odbc, etc.postgres, etc.sqlite ... It needs to be discussed and at some point agreed so that the current 'team' can work toward it for the various databases. We've recently seen an example of an SQLite interface that demonstrated a higher level style where some of the burden of getting SQL right was dealt with by the API. I detected some interest in it. Any further opinions on that? The water gets quite deep quite quickly if you go in that direction though, and think about how more complex SQL commands might be represented, the diversity of SQL dialects, and so on. Somewhere out there I can see etc.postgres.traits and such. Sorry if this is rather long. Steve
