Looking at projects that use APR, many seem to include the entire thing in their code base. I'm guessing that one of the drawbacks is that APR comes with a lot of baggage so to speak. Have you used both libdbi and the database bits of APR? Is there any advantage to using libdbi compared to APR?

At 2015-06-11 09:12, Simon Walter was heard to say: Hi all, I'm new to using libdbi and C in general. I am wondering why libdbi has no support for prepared statements. Is it that because the way libdbi is written, a prepared statement would not provide any benefit? Or is it just lacking that feature? If it's just lacking the feature, are there plans to add that? If the application I'm writing can benefit from prepared statements, I would like to eventually either add that feature to libdbi or I may have to use something else in the future. I haven't taken a deep look at the libdbi code. So any insight is appreciated. Kind regards, Simon PS If I should have sent this to the development list, please let me know. Thanks. Hi, I can't tell if prepared statements would speed up things when accessing databases through libdbi. As in many free software projects, the main reason for the lack of prepared statements is that nobody invested his time in implementing them. This includes myself, although I can't recall many requests for this feature. However, I think libdbi could support prepared statements if someone takes care of it. My commitments to my dayjob and to my family do not leave much dev time currently. If you think about helping to implement this feature, you need to consider both libdbi and libdbi-drivers. libdbi needs a generic interface to prepared statements that covers all database backends. The drivers have to implement the feature using the functions of their respective client libraries. Therefore, it is best to design and discuss the interface first, and then to move on from there. regards, Markus -- Markus Hoenicka http://www.mhoenicka.de AQ score 38 -- ___ libdbi-users mailing list libdbi-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/libdbi-users
