DBIx::Class::Storage::DBI::Sybase::Base - Common functionality for drivers using
DBD::Sybase
-=head1 DESCRIPTION
-
-This is the base class for L<DBIx::Class::Storage::DBI::Sybase> and
-L<DBIx::Class::Storage::DBI::Sybase::Microsoft_SQL_Server>. It provides some
-utility methods related to L<DBD::Sybase> and the supported functions of the
-database you are connecting to.

sub _ping {
return $@ ? 0 : 1;
}
-sub _set_max_connect {
- my $self = shift;
- my $val = shift || 256;
-
- my $dsn = $self->_dbi_connect_info->[0];
-
- return if ref($dsn) eq 'CODE';
-
- if ($dsn !~ /maxConnect=/) {
- $self->_dbi_connect_info->[0] = "$dsn;maxConnect=$val";
- my $connected = defined $self->_dbh;
- $self->disconnect;
- $self->ensure_connected if $connected;
- }
-}
-
-=head2 using_freetds
-
-Whether or not L<DBD::Sybase> was compiled against FreeTDS. If false, it means
-the Sybase OpenClient libraries were used.

-
-sub using_freetds {
- my $self = shift;
-
- return $self->_dbh->{syb_oc_version} =~ /freetds/i;
-}
-
-=head2 set_textsize
-
-When using FreeTDS and/or MSSQL, C<< $dbh->{LongReadLen} >> is not available,
-use this function instead. It does:
-
- $dbh->do("SET TEXTSIZE $bytes");
-
-Takes the number of bytes, or uses the C<LongReadLen> value from your
-L<DBIx::Class/connect_info> if omitted.
