85 | =head2 GETTING HELP | ||||
86 | |||||
87 | If you have questions about DBI, or DBD driver modules, you can get | ||||
88 | help from the I<dbi-users@perl.org> mailing list. You don't have to subscribe | ||||
89 | to the list in order to post, though I'd recommend it. You can get help on | ||||
90 | subscribing and using the list by emailing I<dbi-users-help@perl.org>. | ||||
91 | |||||
92 | I don't recommend the DBI cpanforum (at http://www.cpanforum.com/dist/DBI) | ||||
93 | because relatively few people read it compared with dbi-users@perl.org. | ||||
94 | |||||
95 | To help you make the best use of the dbi-users mailing list, | ||||
96 | and any other lists or forums you may use, I recommend that you read | ||||
97 | "Getting Answers" by Mike Ash: L<http://mikeash.com/getting_answers.html>. | ||||
98 | |||||
99 | If you think you've found a bug then please also read | ||||
100 | "How to Report Bugs Effectively" by Simon Tatham: | ||||
101 | L<http://www.chiark.greenend.org.uk/~sgtatham/bugs.html>. | ||||
102 | |||||
103 | The DBI home page at L<http://dbi.perl.org/> and the DBI FAQ | ||||
104 | at L<http://faq.dbi-support.com/> may be worth a visit. | ||||
105 | They include links to other resources, but are rather out-dated. | ||||
106 | |||||
107 | Before asking any questions, reread this document, consult the | ||||
108 | archives and read the DBI FAQ. The archives are listed | ||||
109 | at the end of this document and on the DBI home page. | ||||
110 | |||||
111 | You might also like to read the Advanced DBI Tutorial at | ||||
112 | L<http://www.slideshare.net/Tim.Bunce/dbi-advanced-tutorial-2007> | ||||
113 | |||||
114 | This document often uses terms like I<references>, I<objects>, | ||||
115 | I<methods>. If you're not familiar with those terms then it would | ||||
116 | be a good idea to read at least the following perl manuals first: | ||||
117 | L<perlreftut>, L<perldsc>, L<perllol>, and L<perlboot>. | ||||
118 | |||||
119 | Please note that Tim Bunce does not maintain the mailing lists or the | ||||
120 | web page (generous volunteers do that). So please don't send mail | ||||
121 | directly to him; he just doesn't have the time to answer questions | ||||
122 | personally. The I<dbi-users> mailing list has lots of experienced | ||||
123 | people who should be able to help you if you need it. If you do email | ||||
124 | Tim he is very likely to just forward it to the mailing list. | ||||
125 | |||||
126 | =head2 NOTES | ||||
127 | |||||
128 | This is the DBI specification that corresponds to DBI version 1.620 | ||||
129 | (see L<DBI::Changes> for details). | ||||
130 | |||||
131 | The DBI is evolving at a steady pace, so it's good to check that | ||||
132 | you have the latest copy. | ||||
133 | |||||
134 | The significant user-visible changes in each release are documented | ||||
135 | in the L<DBI::Changes> module so you can read them by executing | ||||
136 | C<perldoc DBI::Changes>. | ||||
137 | |||||
138 | Some DBI changes require changes in the drivers, but the drivers | ||||
139 | can take some time to catch up. Newer versions of the DBI have | ||||
140 | added features that may not yet be supported by the drivers you | ||||
141 | use. Talk to the authors of your drivers if you need a new feature | ||||
142 | that is not yet supported. | ||||
143 | |||||
144 | Features added after DBI 1.21 (February 2002) are marked in the | ||||
145 | text with the version number of the DBI release they first appeared in. | ||||
146 | |||||
147 | Extensions to the DBI API often use the C<DBIx::*> namespace. | ||||
148 | See L</Naming Conventions and Name Space>. DBI extension modules | ||||
149 | can be found at L<http://search.cpan.org/search?mode=module&query=DBIx>. | ||||
150 | And all modules related to the DBI can be found at | ||||
151 | L<http://search.cpan.org/search?query=DBI&mode=all>. | ||||
