=head1 NAME
DBIx::Class::Storage::DBI::IdentityInsert - Storage Component for Sybase ASE and
MSSQL for Identity Inserts / Updates
=head1 DESCRIPTION
This is a storage component for Sybase ASE
(L<DBIx::Class::Storage::DBI::Sybase::ASE>) and Microsoft SQL Server
(L<DBIx::Class::Storage::DBI::MSSQL>) to support identity inserts, that is
inserts of explicit values into C<IDENTITY> columns.
This is done by wrapping C<INSERT> operations in a pair of table identity
toggles like:
SET IDENTITY_INSERT $table ON
$sql
SET IDENTITY_INSERT $table OFF
=cut
# SET IDENTITY_X only works as part of a statement scope. We can not
# $dbh->do the $sql and the wrapping set()s individually. Hence the
# sql mangling. The newlines are important.
sub _prep_for_execute {
my $self = shift;
return $self->next::method(@_) unless $self->_autoinc_supplied_for_op;
my ($op, $ident) = @_;
my $table = $self->sql_maker->_quote($ident->name);
$op = uc $op;
my ($sql, $bind) = $self->next::method(@_);
return (<<EOS, $bind);
SET IDENTITY_$op $table ON
$sql
SET IDENTITY_$op $table OFF
EOS
}
