Dear monks,
Why was my script below:
use strict;
use Data::Dumper;
use Carp;
use DBI;
my $dsn = 'localhost';
my $user = 'monkfan';
my $password = 'monkfan';
my $dbh = DBI->connect('dbi:mysql:motif_finder','monkfan','monkpwd')
or die "Connection Error: $DBI::errstr\n";
my $sql = "SELECT Symbol FROM gene2go WHERE GeneID=812222";
my $sth = $dbh->prepare($sql);
$sth->execute or die "SQL Error: $DBI::errstr\n";
while ( my @row = $sth->fetchrow_array ) {
print "@row\n";
}
Giving such error message
:!perl test_dbi.pl
+
DBD::mysql::st execute failed: Unknown column 'Symbol' in 'field list'
+ at test_dbi.pl line 21.
SQL Error: Unknown column 'Symbol' in 'field list'
Even though it is clearly shown in the SQL
query below which is equivalent to above Perl script,
is actually working?
mysql> select Symbol from gene_info where GeneID = "812222";
+-----------+
| Symbol |
+-----------+
| PF14_0640 |
+-----------+
1 row in set (13.06 sec)
mysql> show tables;
+------------------------+
| Tables_in_motif_finder |
+------------------------+
| gene2go |
| gene_info |
+------------------------+
2 rows in set (0.00 sec)
mysql> show databases;
+--------------+
| Database |
+--------------+
| motif_finder |
+--------------+
1 rows in set (0.00 sec)

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).
