Hello Everyone,<BR>
It's getting late here and my brain is fried, so I am casting this problem out to the monks to help me if possible.<P>
I am writing a DBD::ANYDATA sql script (below) which I want to update the "wins" field in an existing table. I presently get the following error:<P>
<blockquote>Execution ERROR: No such column 'JUDOKA.WINS' called from /nfs/cust/4/7/3/judoco/e-judo/simulate.cgi at 197.</blockquote>
<P>
The segment of code in question is:<P>
<code>
# Use DBI to connect to the judoka_csv datafile
#-----------------------------------------------
my $dbh = DBI->connect('dbi:AnyData(RaiseError=>1):'); # tell DBI we want to use the Anydata module in ./MyLibs
$dbh->func( 'judoka', 'CSV', 'data/judoka_csv', 'ad_catalog'); # Connect to the users_csv data file
# select from the datafile the id for the user ID from the array paased from the previous sub routine
my $sql_query = "SELECT * FROM judoka WHERE judoka_id = ?"; # this is the SQL command we want to execute
my $sql_params = ($winner); # Theese are the parameteres we will use in the SQL command above
print $query->p("$sql_query\n[$sql_params]\n") if $DEBUG; # if we are in debug mode print the SQL statement
my $sth = $dbh->prepare( $sql_query ); # prepare the SQL command
$sth->execute( $sql_params ); # excecute the SQL using our parameters
my @winner_data = $sth->fetchrow_array; # this line takes the results of the select and puts it in the array called RESULTS
$dbh->disconnect(); # we are done with the datbase for now, so disconnect from it (MAY NOT BE NECESSARY)
print $query->p("result = ", @winner_data)if $DEBUG; # Prints the result of our SQL command if we are in debug mode.
# grab the number of wins and then add one to it and insert back into the DB
my $wins = $winner_data[10] + 1;
print $query->p("winner =",$winner," and Wins = ", $wins)if $DEBUG;
my $sql_insert ="UPDATE judoka SET wins = ? WHERE judoka_id = ?";
my @sql_insert_params = ($wins,$winner);
print $query->p("$sql_insert\n[@sql_insert_params]\n") if $DEBUG; # if we are in debug mode print the SQL statement
$sth = $dbh->prepare( $sql_insert ); # prepare the SQL command
$sth->execute( @sql_insert_params ); # excecute the SQL using our parameters
</code>
Please forgive the messy code and what is no doubt a simple problem!
