dbix::contextualfetch
DBIx::ContextualFetch(3pm) User Contributed Perl Documentation DBIx::ContextualFetch(3pm)NAME
DBIx::ContextualFetch - Add contextual fetches to DBI
SYNOPSIS
my $dbh = DBI->connect(...., { RootClass => "DBIx::ContextualFetch" });
# Modified statement handle methods.
my $rv = $sth->execute;
my $rv = $sth->execute(@bind_values);
my $rv = $sth->execute(@bind_values, @bind_cols);
# In addition to the normal DBI sth methods...
my $row_ref = $sth->fetch;
my @row = $sth->fetch;
my $row_ref = $sth->fetch_hash;
my %row = $sth->fetch_hash;
my $rows_ref = $sth->fetchall;
my @rows = $sth->fetchall;
my $rows_ref = $sth->fetchall_hash;
my @tbl = $sth->fetchall_hash;
DESCRIPTION
It always struck me odd that DBI didn't take much advantage of Perl's context sensitivity. DBIx::ContextualFetch redefines some of the
various fetch methods to fix this oversight. It also adds a few new methods for convenience (though not necessarily efficiency).
SET-UP
my $dbh = DBIx::ContextualFetch->connect(@info);
my $dbh = DBI->connect(@info, { RootClass => "DBIx::ContextualFetch" });
To use this method, you can either make sure that everywhere you normall call DBI->connect() you either call it on DBIx::ContextualFetch,
or that you pass this as your RootClass. After this DBI will Do The Right Thing and pass all its calls through us.
EXTENSIONS
execute
$rv = $sth->execute;
$rv = $sth->execute(@bind_values);
$rv = $sth->execute(@bind_values, @bind_cols);
execute() is enhanced slightly:
If called with no arguments, or with a simple list, execute() operates normally. When when called with two array references, it performs
the functions of bind_param, execute and bind_columns similar to the following:
$sth->execute(@bind_values);
$sth->bind_columns(undef, @bind_cols);
In addition, execute will accept tainted @bind_values. I can't think of what a malicious user could do with a tainted bind value (in the
general case. Your application may vary.)
Thus a typical idiom would be:
$sth->execute([$this, $that], [($foo, $bar)]);
Of course, this method provides no way of passing bind attributes through to bind_param or bind_columns. If that is necessary, then you
must perform the bind_param, execute, bind_col sequence yourself.
fetch
$row_ref = $sth->fetch;
@row = $sth->fetch;
A context sensitive version of fetch(). When in scalar context, it will act as fetchrow_arrayref. In list context it will use
fetchrow_array.
fetch_hash
$row_ref = $sth->fetch_hash;
%row = $sth->fetch_hash;
A modification on fetchrow_hashref. When in scalar context, it acts just as fetchrow_hashref() does. In list context it returns the
complete hash.
fetchall
$rows_ref = $sth->fetchall;
@rows = $sth->fetchall;
A modification on fetchall_arrayref. In scalar context it acts as fetchall_arrayref. In list it returns an array of references to rows
fetched.
fetchall_hash
$rows_ref = $sth->fetchall_hash;
@rows = $sth->fetchall_hash;
A mating of fetchall_arrayref() with fetchrow_hashref(). It gets all rows from the hash, each as hash references. In scalar context it
returns a reference to an array of hash references. In list context it returns a list of hash references.
