86 | =head2 GETTING HELP | ||||
87 | |||||
88 | =head3 General | ||||
89 | |||||
90 | Before asking any questions, reread this document, consult the | ||||
91 | archives and read the DBI FAQ. The archives are listed | ||||
92 | at the end of this document and on the DBI home page L<http://dbi.perl.org/support/> | ||||
93 | |||||
94 | You might also like to read the Advanced DBI Tutorial at | ||||
95 | L<http://www.slideshare.net/Tim.Bunce/dbi-advanced-tutorial-2007> | ||||
96 | |||||
97 | To help you make the best use of the dbi-users mailing list, | ||||
98 | and any other lists or forums you may use, I recommend that you read | ||||
99 | "Getting Answers" by Mike Ash: L<http://mikeash.com/getting_answers.html>. | ||||
100 | |||||
101 | =head3 Mailing Lists | ||||
102 | |||||
103 | If you have questions about DBI, or DBD driver modules, you can get | ||||
104 | help from the I<dbi-users@perl.org> mailing list. This is the best way to get | ||||
105 | help. You don't have to subscribe to the list in order to post, though I'd | ||||
106 | recommend it. You can get help on subscribing and using the list by emailing | ||||
107 | I<dbi-users-help@perl.org>. | ||||
108 | |||||
109 | Please note that Tim Bunce does not maintain the mailing lists or the | ||||
110 | web pages (generous volunteers do that). So please don't send mail | ||||
111 | directly to him; he just doesn't have the time to answer questions | ||||
112 | personally. The I<dbi-users> mailing list has lots of experienced | ||||
113 | people who should be able to help you if you need it. If you do email | ||||
114 | Tim he is very likely to just forward it to the mailing list. | ||||
115 | |||||
116 | =head3 IRC | ||||
117 | |||||
118 | DBI IRC Channel: #dbi on irc.perl.org (L<irc://irc.perl.org/#dbi>) | ||||
119 | |||||
120 | =for html <a href="http://chat.mibbit.com/#dbi@irc.perl.org">(click for instant chatroom login)</a> | ||||
121 | |||||
122 | =head3 Online | ||||
123 | |||||
124 | StackOverflow has a DBI tag L<http://stackoverflow.com/questions/tagged/dbi> | ||||
125 | with over 400 questions. | ||||
126 | |||||
127 | The DBI home page at L<http://dbi.perl.org/> and the DBI FAQ | ||||
128 | at L<http://faq.dbi-support.com/> may be worth a visit. | ||||
129 | They include links to other resources, but I<are rather out-dated>. | ||||
130 | |||||
131 | I don't recommend the DBI cpanforum (at http://www.cpanforum.com/dist/DBI) | ||||
132 | because relatively few people read it compared with dbi-users@perl.org. | ||||
133 | |||||
134 | =head3 Reporting a Bug | ||||
135 | |||||
136 | If you think you've found a bug then please read | ||||
137 | "How to Report Bugs Effectively" by Simon Tatham: | ||||
138 | L<http://www.chiark.greenend.org.uk/~sgtatham/bugs.html>. | ||||
139 | |||||
140 | If you think you've found a memory leak then read L</Memory Leaks>. | ||||
141 | |||||
142 | Your problem is most likely related to the specific DBD driver module you're | ||||
143 | using. If that's the case then click on the 'Bugs' link on the L<http://metacpan.org> | ||||
144 | page for your driver. Only submit a bug report against the DBI itself if you're | ||||
145 | sure that your issue isn't related to the driver you're using. | ||||
146 | |||||
147 | =head2 NOTES | ||||
148 | |||||
149 | This is the DBI specification that corresponds to DBI version 1.634 | ||||
150 | (see L<DBI::Changes> for details). | ||||
151 | |||||
152 | The DBI is evolving at a steady pace, so it's good to check that | ||||
153 | you have the latest copy. | ||||
154 | |||||
155 | The significant user-visible changes in each release are documented | ||||
156 | in the L<DBI::Changes> module so you can read them by executing | ||||
157 | C<perldoc DBI::Changes>. | ||||
158 | |||||
159 | Some DBI changes require changes in the drivers, but the drivers | ||||
160 | can take some time to catch up. Newer versions of the DBI have | ||||
161 | added features that may not yet be supported by the drivers you | ||||
162 | use. Talk to the authors of your drivers if you need a new feature | ||||
163 | that is not yet supported. | ||||
164 | |||||
165 | Features added after DBI 1.21 (February 2002) are marked in the | ||||
166 | text with the version number of the DBI release they first appeared in. | ||||
167 | |||||
168 | Extensions to the DBI API often use the C<DBIx::*> namespace. | ||||
169 | See L</Naming Conventions and Name Space>. DBI extension modules | ||||
170 | can be found at L<https://metacpan.org/search?q=DBIx>. And all modules | ||||
171 | related to the DBI can be found at L<https://metacpan.org/search?q=DBI>. | ||||
