-DBIx::Class::Storage::DBI::Sybase - Storage::DBI subclass for Sybase

-=head1 SYNOPSIS
+ ( dbic_internal_try { $dbh->do('select 1'); 1 } )
+ ? 1
+ : 0
+ ;
+}
-This subclass supports L<DBD::Sybase> for real Sybase databases. If
-you are using an MSSQL database via L<DBD::Sybase>, see
-L<DBIx::Class::Storage::DBI::Sybase::MSSQL>.
+sub _set_max_connect {
+ my $self = shift;
+ my $val = shift || 256;
-=head1 CAVEATS
+ my $dsn = $self->_dbi_connect_info->[0];
-This storage driver uses L<DBIx::Class::Storage::DBI::NoBindVars> as a base.
-This means that bind variables will be interpolated (properly quoted of course)
-into the SQL query itself, without using bind placeholders.
+ return if ref($dsn) eq 'CODE';
-More importantly this means that caching of prepared statements is explicitly
-disabled, as the interpolation renders it useless.
+ if ($dsn !~ /maxConnect=/) {
+ $self->_dbi_connect_info->[0] = "$dsn;maxConnect=$val";
+ my $connected = defined $self->_dbh;
+ $self->disconnect;
+ $self->ensure_connected if $connected;
+ }

+# Whether or not DBD::Sybase was compiled against FreeTDS. If false, it means
