Re: DBI - retrieving a specific row

[Trimbach]

If all you want is a specific row from the database you can do something like this:

my $sth=$dbh->prepare("SELECT * FROM my_table WHERE primary_key = ?");

$sth->execute(4);
    
my @record = $sth->fetchrow();

It's really no big deal, and doesn't require any freaky LIMIT or anything like that. Of course, this assumes that your SELECT will only return one row (which it will, if you're SELECTing from a Primary Key).

Update:Whoops. Misunderstood what the poster wanted. Ah well... hakkr's post has what you want.

Let's take it a step further.

Let's say I have a group of records and I want to do a data slice. What I mean by this is say I have 50 records but I only want to display 10 records at a time. Say then I indicate I want slice 3; I would be viewing records 21-30 (1=1-10, 2=11-20, ...).

Is it possible to make a query call to the DBI that would allow for this sort of functionality? LIMIT seemed like the way to go but it appears that LIMIT is not supported in SQL::Statement.
