This project implements a NuoDB DBD Module for Perl DBI. This is a community-driven driver with limited support and testing from NuoDB.

• Perl DBI module. Use your package manager, or else CPAN: sudo perl -MCPAN -e 'force install DBI'
• NuoDB. This driver uses the Perl XS interface with the NuoDB client shared library.

If you install NuoDB using your package manager, replace $NUODB_HOME below with the standard path /opt/nuodb.

If you download the NuoDB tar file package, replace $NUODB_HOME below with the path to the unpacked directory. In this situation you don't need to use sudo to manage the NuoDB Broker.

Run the following command to build the module:

perl Makefile.PL --nuodb-libs="$NUODB_HOME/lib64" --nuodb-includes="$NUODB_HOME/include"

The tests included with the module assume that a NuoDB database named test exists, with a DBA user dba and password goalie.

For details on starting and managing NuoDB databases, see the Documentation.

If you have not configured and started a NuoDB Broker on your host, do so:

DOMAIN_PWD=bird
printf '\ndomainPassword = '"$DOMAIN_PWD"'\n' | sudo tee -a "$NUODB_HOME"/etc/default.properties >/dev/null
sudo "$NUODB_HOME"/etc/nuoagent start

If you have already configured and started a NuoDB Broker, replace $DOMAIN_PWD with your domain password in the commands below.

Create a database test:

"$NUODB_HOME"/bin/nuodbmgr --broker localhost --password "$DOMAIN_PWD" \
    --command "start process sm database test host localhost archive /tmp/nuoarchive initialize true"
"$NUODB_HOME"/bin/nuodbmgr --broker localhost --password "$DOMAIN_PWD" \
    --command "start process te database test host localhost options '--dba-user dba --dba-password goalie'"

Once the database is running, test the module with:

make test

Be sure to shut down the database once your testing is complete:

"$NUODB_HOME"/bin/nuodbmgr --broker localhost --password "$DOMAIN_PWD" \
    --command "shutdown database database test"

Run the following commands to install the module:

sudo make install

Here is an example:

use DBI;
my $dbh = DBI->connect("dbi:NuoDB:$database\@$host:$port", $username, $password, {schema => $schema});
my $sth = $dbh->prepare("SELECT 'one' FROM DUAL");
$sth->execute();
my ($value) = $sth->fetchrow_array();

The following features have been implemented:

• DSNs in the form dbi:NuoDB:database@host:port?property=value
• Schema selection via the "schema" handle attribute
• Transactions, commit(), rollback() and the AutoCommit handle attribute
• prepare(), execute(), fetch() as well as the combined convenience functions such as selectall_arrayref()

The following have not been implemented yet:

• All result values are returned as strings regardless of the original data type
• Metadata methods have not been implemented
• Queries or bind values containing \0 will most likely be truncated
• Windows has not been tested

• NuoDB
• NuoDB Documentation
