    <p>I'm trying to code a very simple MySQL SELECT query, as per attached :</p> <pre><code># # MODULES # use strict; use DBI; use DBD::mysql; # # CONNECT # my $dbd = DBI-&gt;connect("dbi:mysql:dbname=$db_name;host=$host;mysql_server_prepare=1;",$db_user, $db_pwd) or die 'No connection to dB : '.DBI::errstr; # # PREPARE # my $query = "SELECT * FROM $table WHERE $search_field = ? "; my $prep = $dbd-&gt;prepare($query) or die "ERR: " .$dbd-&gt;errstr; # # EXECUTE # $prep-&gt;execute( $search_data ) or die 'ERR : '.$prep-&gt;errstr; # # SHOW # while (my @data = $prep-&gt;fetchrow_array ) { foreach my $line (@data) { print $line.', '; } print "\n"; } </code></pre> <p>The search field with TinyText. (but tried also varchar, same result) The search field is encoded utf8_unicode_ci (but tried also latin_general_ci, same result)</p> <p>If I run the request with a number-only chain for $search_data (like 0124345): ok, I get the result<br> If I run the request with a text-only chain for $search_data (like AZERTY): ok, I get the result </p> <p>BUT:</p> <p>If I run the request with a mix text/numbers (like AZERTY01234) : No record found,<br> If I run the request with a mix text with dash, dot etc (like foo-bar): No record found<br> If I run the request with a mix text with dash, dot etc (like foo+bar): No record found</p> <p>I tried several potential fix but no success. (changing SQL data type, with and w/o simple/double quotes, no prepared query ...)</p> <p>I have no idea why and how to get it solved.</p> <p>Thx in advance for some hints.</p>

    3. COWhat do you expect to be returned for "like foo-bar" ? Every row that contains a search_field that literally contains "foo-bar" - or every row whose search_field contains "foo" but does not contain "bar" ?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
