Happy New Year for all the monks!
I have the following problem:I want to delete from a database the records
that are NOT equal with the elements of an array.
my @test=("Anna","Maria","Carmen")
foreach $line(@test){
my $sth=$dbh->prepare(qq{DELETE FROM tnt WHERE `Name`!=\"$lin
+e\"});
$sth->execute();
$sth->finish;
}
If I have in the database the record "Diana" I want to erase it because it's not an element of the array @test.
In the way i do it it deletes all the records from the database.
Thank you very much for your time.

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).

or How to display code and escape characters
are good places to start.
