=head1 DESCRIPTION
DBD::cubrid is a Perl module that works with the DBI module to provide access to
CUBRID databases.
=head1 Module Documentation
This documentation describes driver specific behavior and restrictions. It is
not supposed to be used as the only reference for the user. In any case
consult the B<DBI> documentation first!
=for html <a href="http://search.cpan.org/~timb/DBI/DBI.pm">Latest DBI documentation.</a>
=head1 THE DBI CLASS
=head2 DBI Class Methods
=head3 B<connect>
use DBI;
$dsn = "DBI:cubrid:database=$database";
$dsn = "DBI:cubrid:database=$database;host=$hostname";
$dsn = "DBI:cubrid:database=$database;host=$hostname;port=$port";
$dbh = DBI->connect ($dsn, $user, $password);
This method creates a database handle by connecting to a database, and is the DBI
equivalent of the "new" method. You can also use "dbi:cubrid..." in $dsn. There
are some properties you can configure when create the conntion.
If the HA feature is enabled, you munst specify the connection information of the
standby server, which is used for failover when failure occurs, in the url string
argument of this function.
B<althosts>=standby_broker1_host,standby_broker2_host, . . . : String. Specifies the
broker information of the standby server, which is used for failover when it is
impossible to connect to the active server. You can specify multiple brokers for failover,
and the connection to the brokers is attempted in the order listed in alhosts.
B<rctime> : INT. An interval between the attempts to connect to the active broker in
which failure occurred. After a failure occurs, the system connects to the broker
specified by althosts (failover), terminates the transaction, and then attempts to
connect to he active broker of the master database at every rctime. The default value
is 600 seconds.
B<login_timeout> : INT. Configures the login timeout of CUBRID.
B<query_timeout>: INT. Configures the query timeout of CUBRID.
B<disconnect_on_query_timeout> : String. Make the query_timeout effective.
The value maybe true, on, yes, false, off and no.
The following are some examples about different $dsn:
$db = "testdb";
$host= "192.168.10.29";
$port = 33088;
$dsn = "dbi:cubrid:database=$db;host=$host;port=$port";
# connection $dsn string when property(alhosts) specified for HA
$alhosts = "192.168.10.28:31000,192.168.10.27:33055";
$dsn = "dbi:cubrid:database=$db;host=$host;port=$port;alhosts=$alhosts";
# connection $dsn string when property(alhosts, rctime) specified for HA
$rctime = 1000;
$dsn = "dbi:cubrid:database=$db;host=$host;port=$port;alhosts=$alhosts;rctime=$rctime";
$query = 600;
$dsn = "dbi:cubrid:database=$db;host=$host;port=$port;query_timeout=$query;disconnect_on_query_timeout=yes";
B<Tips: the autocommit has been removed from the dsn since RB-8.4.4. If you wanna set up the autocommit of the connection, you have to do:>
$dbh= DBI->connect ($dsn, $user, $password,
{ RaiseError => 1, PrintError => 1, AutoCommit => 0 });
=head1 DBI Database Handle Object
=head2 Database Handle Methods
=head3 B<do>
$rows = $dbh->do ($statement) or die $dbh->errstr;
$rows = $dbh->do ($statement, \%attr) or die $dbh->errstr;
$rows = $dbh->do ($statement, \%attr, @bind_values);
Prepare and execute a single statement. Returns the number of rows affected or undef
on error. A return value of -1 means the number of rows is not known, not applicable,
or not available. For example:
$dbh->do ("CREATE TABLE test_cubrid (id INT, name varchar(60))");
$dbh->do ("INSERT INTO test_cubrid VALUES (1, 'Jobs')")
$dbh->do ("INSERT INTO test_cubrid VALUES (?, ?)", undef, (2, "Gate"));
=head3 B<prepare>
$sth = $dbh->prepare ($statement, \%attr);
Prepares a statement for later execution by the database engine and returns a reference
to a statement handle object. You can get C<$sth-E<gt>{NUM_OF_PARAMS}> after the statement
prepared.
=head3 B<commit>
$dbh->commit or die $dbh->errstr;
Issues a COMMIT to the server, indicating that the current transaction is finished and
that all changes made will be visible to other processes. If AutoCommit is enabled,
then a warning is given and no COMMIT is issued. Returns true on success, false on error.
=head3 B<rollback>
$dbh->rollback or dir $dbh->errstr;
Issues a ROLLBACK to the server, which discards any changes made in the current transaction.
If AutoCommit is enabled, then a warning is given and no ROLLBACK is issued. Returns true
on success, and false on error.
=head3 B<disconnect>
$dbh->disconnect or warn $dbh->errstr;
Disconnects from the CUBRID database. If the C<AutoCommit> is on, any uncommitted changes
will be committed before disconnect is called. Otherwise, it will roll back.
=head3 B<selectall_arrayref>
$ary_ref = $dbh->selectall_arrayref ($statement);
$ary_ref = $dbh->selectall_arrayref ($statement, \%attr);
$ary_ref = $dbh->selectall_arrayref ($statement, \%attr, @bind_values);
Returns a reference to an array containing the rows returned by preparing and executing
the SQL string. See the DBI documentation for full details.
=head3 B<selectall_hashref>
$hash_ref = $dbh->selectall_hashref ($statement, $key_field);
Returns a reference to a hash containing the rows returned by preparing and executing
the SQL string. See the DBI documentation for full details.
=head3 B<selectcol_arrayref>
$ary_ref = $dbh->selectcol_arrayref ($statement, \%attr, @bind_values);
Returns a reference to an array containing the first column from each rows returned by
preparing and executing the SQL string. It is possible to specify exactly which columns
to return. See the DBI documentation for full details.
=head3 B<selectrow_array>
@row_ary = $dbh->selectrow_array ($statement);
@row_ary = $dbh->selectrow_array ($statement, \%attr);
@row_ary = $dbh->selectrow_array ($statement, \%attr, @bind_values);
Returns an array of row information after preparing and executing the provided SQL string.
The rows are returned by calling L</fetchrow_array>. The string can also be a statement handle
generated by a previous prepare. Note that only the first row of data is returned. If called
in a scalar context, only the first column of the first row is returned. Because this is not
portable, it is not recommended that you use this method in that way.
=head3 B<selectrow_arrayref>
@row_ary = $dbh->selectrow_arrayref ($statement);
@row_ary = $dbh->selectrow_arrayref ($statement, \%attr);
@row_ary = $dbh->selectrow_arrayref ($statement, \%attr, @bind_values);
Exactly the same as L</selectrow_array>, except that it returns a reference to an array, by
internal use of the L</fetchrow_arrayref> method.
=head3 B<selectrow_hashref>
$hash_ref = $dbh->selectrow_hashref ($statement);
$hash_ref = $dbh->selectrow_hashref ($statement, \%attr);
$hash_ref = $dbh->selectrow_hashref ($statement, \%attr, @bind_values);
Exactly the same as L</selectrow_array>, except that it returns a reference to an hash, by
internal use of the L</fetchrow_hashref> method.
=head3 B<last_insert_id>
$insert_id = $dbh->last_insert_id ($catalog, $schema, $table, $field);
$insert_id = $dbh->last_insert_id ($catalog, $schema, $table, $field, \%attr);
Attempts to retrieve the ID generated for the AUTO_INCREMENT column which is updated by the
previous INSERT query. This method only be available immediately after the insert statement
has executed for CUBRID. And CUBRID will also ignore the $catalog, $schema, $table and $field
parameters. CUBRID will return NULL if no last insert id. For example:
$insert_id = $dbh->last_insert_id (undef, undef, undef, undef);
=head3 B<ping>
$rv = $dbh->ping;
This method is used to check the validity of a database handle. The value returned is either 0,
indicating that the connection is no longer valid, or 1, indicating the connection is valid.
=head3 B<get_info>
$value = $dbh->get_info ($info_type);
DBD::cubrid supports C<get_info()>, bug (currently) only a few info types.
=head3 B<table_info>
$sth = $dbh->table_info ($catalog, $schema, $table, $type);
#then $sth->fetchall_arrayref or $sth->fetchall_hashref etc
DBD::cubrid supports attributes for C<table_info()>.
In CUBRID, this method will return all tables and views visible to the current user.
CUBRID doesn't support catalog and schema now. The table argument will do a LIKE search
if a percent sign (%) or an underscore (_) is detected in the argment. The type argument
accepts a value of either "TABLE" or "VIEW" (using both is the defualt action). Note
that a statement handle is returned, not a direct list of table. See the examples below
for ways to handle this.
The following fields are returned:
B<TABLE_CAT>: Always NULL, as CUBRID doesn't have the concept of catalogs.
B<TABLE_SCHEM>: Always NULL, as CUBRID doesn't have the concept of schemas.
B<TABLE_NAME>: Name of the table (or view, synonym, etc).
B<TABLE_TYPE>: The type of object returned. It will be "TABLE" or "VIEW".
B<REMARKS>: A description of the table. Always NULL (undef).
Examples of use:
# Display all tables and views to the current user
$sth = $dbh->table_info (undef, undef, undef, undef);
for my $info (@{$sth->fetchall_arrayref({})}) {
print "\$info->{TABLE_NAME} = $info->{TABLE_NAME} \t \$info->{TABLE_TYPE} = $info->{TABLE_TYPE}\n";
}
# Display the specified table
$sth = $dbh->table (undef, undef, 'test_%', undef);
for my $info (@{$sth->fetchall_arrayref({})}) {
print "\$info->{TABLE_NAME} = $info->{TABLE_NAME} \t \$info->{TABLE_TYPE} = $info->{TABLE_TYPE}\n";
}
=head3 B<tables>
@names = $dbh->tables ($catalog, $schema, $table, $type);
Simple interface to L</table_info>. Returns a list of matching table names.
See more information in DBI document;
=head3 B<primary_key_info>
$sth = $dbh->primary_key_info ($catalog, $schema, $table);
# then $sth->fetchall_arrayref or $sth->fetchall_hashref etc
CUBRID does not support catalogues and schemas so TABLE_CAT and TABLE_SCHEM are ignored
as selection criterion. The TABLE_CAT and TABLE_SCHEM fields of a fetched row is always
NULL (undef).
The result set is ordered by TABLE_NAME, COLUMN_NAME, KEY_SEQ, and PK_NAME.
