Re^3: DBI - Table names & placeholders

The bottom loop should be

for (@$sales_inserts) {
    my $table = shift(@$_);
    my $sth = $dbh->prepare('
        INSERT INTO '.$dbh->quote_identifier($table).' (
                   ItemID, Day, Revenue, Count
               ) VALUES (
                   ?, ?, ?, ?
               )
    ');
    $sth->execute(@$_);
}

or

my %sth_cache;
for (@$sales_inserts) {
    my $table = shift(@$_);
    my $sth = $sth_cache{$table} ||= $dbh->prepare('
        INSERT INTO '.$dbh->quote_identifier($table).' (
                   ItemID, Day, Revenue, Count
               ) VALUES (
                   ?, ?, ?, ?
               )
    ');
    $sth->execute(@$_);
}

Thanks.

A variation on your first example did the trick for me. Still not exactly what I would have liked, but it gets the job done :)

Cheers,

Maybe if you told us what you wanted?

Well, it just irks me that I have to do a separate prepare and execute for every single row of data that I want to insert - as opposed to "prepare once, execute many times".

But, it's no biggie - the job is done and the data is flowing.
