I think you're mixing up layers.

DBI is the interface your Perl program uses to the high-level database routines. Those routines in turn call the low-level backend routines that are database specific.

One of these backend routines is ODBC, which itself is an indirection layer to let many databases have a similar API.

So it'd go yourcode -to- DBI -to- DBD::ODBC -to- random back end

Sure, you can certainly talk directly to ODBC, but then you'd lose the option to go with a non-ODBC backend by changing just a few lines of code, such as mysql via: yourcode -to- DBI -to- DBD::mysql -to- mysql API.

So, ODBC doesn't replace DBI. DBI doesn't replace ODBC. They're indirections at different levels.

Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
