NAME

DBD::mysqlPPrawSjis - Pure Perl MySQL driver for raw ShiftJIS

SYNOPSIS

use DBI;

$dsn = "dbi:mysqlPPrawSjis:database=$database;host=$hostname";

$dbh = DBI->connect($dsn, $user, $password);

$drh = DBI->install_driver("mysqlPPrawSjis");

$sth = $dbh->prepare("SELECT * FROM foo WHERE bla");
$sth->execute;
$numRows = $sth->rows;
$numFields = $sth->{'NUM_OF_FIELDS'};
$sth->finish;

EXAMPLE

#!/usr/bin/perl

use strict;
use DBI;

# Connect to the database.
my $dbh = DBI->connect("dbi:mysqlPPrawSjis:database=test;host=localhost",
                       "joe", "joe's password",
                       {'RaiseError' => 1});

# Drop table 'foo'. This may fail, if 'foo' doesn't exist.
# Thus we put an eval around it.
eval { $dbh->do("DROP TABLE foo") };
print "Dropping foo failed: $@\n" if $@;

# Create a new table 'foo'. This must not fail, thus we don't
# catch errors.
$dbh->do("CREATE TABLE foo (id INTEGER, name VARCHAR(20))");

# INSERT some data into 'foo'. We are using $dbh->quote() for
# quoting the name.
$dbh->do("INSERT INTO foo VALUES (1, " . $dbh->quote("Tim") . ")");

# Same thing, but using placeholders
$dbh->do("INSERT INTO foo VALUES (?, ?)", undef, 2, "Jochen");

# Now retrieve data from the table.
my $sth = $dbh->prepare("SELECT id, name FROM foo");
$sth->execute();
while (my $ref = $sth->fetchrow_arrayref()) {
  print "Found a row: id = $ref->[0], name = $ref->[1]\n";
}
$sth->finish();

# Disconnect from the database.
$dbh->disconnect();

DESCRIPTION

DBD::mysqlPPrawSjis is a Pure Perl client interface for the MySQL database. This module implements network protool between server and client of MySQL, thus you don't need external MySQL client library like libmysqlclient for this module to work. It means this module enables you to connect to MySQL server from some operation systems which MySQL is not ported. Using this software and Sjis software, you can store ShiftJIS literal into MySQL database without code conversion at all. How nifty!

From perl you activate the interface with the statement

use DBI;

After that you can connect to multiple MySQL database servers and send multiple queries to any of them via a simple object oriented interface. Two types of objects are available: database handles and statement handles. Perl returns a database handle to the connect method like so:

$dbh = DBI->connect("dbi:mysqlPPrawSjis:database=$db;host=$host",
            $user, $password, {RaiseError => 1});

Once you have connected to a database, you can can execute SQL statements with:

my $query = sprintf("INSERT INTO foo VALUES (%d, %s)",
            $number, $dbh->quote("name"));
$dbh->do($query);

See DBI(3) for details on the quote and do methods. An alternative approach is

$dbh->do("INSERT INTO foo VALUES (?, ?)", undef,
     $number, $name);

in which case the quote method is executed automatically. See also the bind_param method in DBI(3). See "DATABASE HANDLES" below for more details on database handles.

If you want to retrieve results, you need to create a so-called statement handle with:

$sth = $dbh->prepare("SELECT id, name FROM $table");
$sth->execute();

This statement handle can be used for multiple things. First of all you can retreive a row of data:

my $row = $sth->fetchow_arrayref();

If your table has columns ID and NAME, then $row will be array ref with index 0 and 1. See "STATEMENT HANDLES" below for more details on statement handles.

I's more formal approach:

Class Methods

connect

use DBI;

$dsn = "dbi:mysqlPPrawSjis:$database";
$dsn = "dbi:mysqlPPrawSjis:database=$database;host=$hostname";
$dsn = "dbi:mysqlPPrawSjis:database=$database;host=$hostname;port=$port";

$dbh = DBI->connect($dsn, $user, $password);

A database must always be specified.

host: The hostname, if not specified or specified as '', will default to an MySQL daemon running on the local machine on the default port for the INET socket.
port: Port where MySQL daemon listens to. default is 3306.

MetaData Method

tables

@names = $dbh->tables;

Returns a list of table and view names, possibly including a schema prefix. This list should include all tables that can be used in a "SELECT" statement without further qualification.

Private MetaData Methods

ListDBs

@dbs = $dbh->func('_ListDBs');

Returns a list of all databases managed by the MySQL daemon.

ListTables

WARNING: This method is obsolete due to DBI's $dbh->tables().

@tables = $dbh->func('_ListTables');

Once connected to the desired database on the desired mysql daemon with the "DBI-"connect()> method, we may extract a list of the tables that have been created within that database.

"ListTables" returns an array containing the names of all the tables present within the selected database. If no tables have been created, an empty list is returned.

@tables = $dbh->func('_ListTables');
foreach $table (@tables) {
    print "Table: $table\n";
}

DATABASE HANDLES

The DBD::mysqlPPrawSjis driver supports the following attributes of database handles (read only):

$insertid = $dbh->{'mysqlpprawsjis_insertid'};
$insertid = $dbh->{'mysql_insertid'};

STATEMENT HANDLES

The statement handles of DBD::mysqlPPrawSjis support a number of attributes. You access these by using, for example,

my $numFields = $sth->{'NUM_OF_FIELDS'};

mysqlpprawsjis_insertid/mysql_insertid: MySQL has the ability to choose unique key values automatically. If this happened, the new ID will be stored in this attribute. An alternative way for accessing this attribute is via $dbh->{'mysqlpprawsjis_insertid'}. (Note we are using the $dbh in this case!)
NUM_OF_FIELDS: Number of fields returned by a SELECT statement. You may use this for checking whether a statement returned a result. A zero value indicates a non-SELECT statement like INSERT, DELETE or UPDATE.

INSTALLATION

Raw ShiftJIS

The "ShiftJIS" in this software means widely codeset than general ShiftJIS. When the character is taken out of the octet string, it is necessary to distinguish a single octet character and the double octet character. The distinction is done only by first octet.

Single octet code is:
  0x00-0x7F, 0x81-0x9F and 0xA1-0xFC

Double octet code is:
  First octet   0x81-0x9F, 0xE0-0xEF and 0xF0-0xFC
  Second octet  0x40-0x7E and 0x80-0xFC

*MALFORMED* single octet code is:
  0x80, 0xA0 and 0xFD-0xFF
  Single octet code that cannot be used
