( [id://3333]=superdoc: print w/replies, xml ) Need Help??
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)

Regards,
Edward

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • 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).
  • Want more info? How to link or How to display code and escape characters are good places to start.
