If the questioner is unaware of how to use perldoc, and
most questioners indeed are, then your post amounts to
saying, You are a moron for not doing something you
don't know how to do. Why didn't you look up documentation
you probably don't know how to find?
That is an absolutely and utterly useless thing to say.
Here is a much better way at getting across the basic
point you had:
It looks like you may not have read the documentation for
DBI. If you know about it, take this as advice that you
should try understanding that before asking questions. If
you don't know how to find the documentation try typing
perldoc DBI at the command line. To try to
find out about a specific thing type </code>/execute</code>
and you should jump right there.
An alternative that many people like to use is the
documentation at the website http://www.perldoc.com.
Note, however, that using this is slower, and using any kind
of online documentation means you always have to worry about
whether you are reading documentation for a different
version of the software than what you have installed
Do you see? The same basic diagnosis. Answering it takes
about the same energy as what you did. The answer is far
less likely to leave the other person thinking you think
they are stupid. And in the likely scenario that they
don't have the basic toolkit that you take for granted,
the answer will be useful.
