DBD::ODBC Perl module contains a ODBC Driver for DBI.

SYNOPSIS

use DBI;

$dbh = DBI->connect(dbi:ODBC:DSN, user, password);

Private DBD::ODBC Attributes

odbc_more_results (applies to statement handle only!)
Use this attribute to determine if there are more result sets available. SQL Server supports this feature. Use this as follows:

do { my @row; while (@row = $sth->fetchrow_array()) { # do stuff here } } while ($sth->{odbc_more_results});

Note that with multiple result sets and output parameters (i.e. using bind_param_inout, dont expect output parameters to be bound until ALL result sets have been retrieved.
odbc_ignore_named_placeholders

Use this if you have special needs (such as Oracle triggers, etc) where :new or :name mean something special and are not just place holder names You must then use ? for binding parameters. Example: $dbh->{odbc_ignore_named_placeholders} = 1; $dbh->do("create trigger foo as if :new.x :old.x then ... etc");

Without this, DBD::ODBC will think :new and :old are placeholders for binding and get confused.

odbc_default_bind_type

This value defaults to 0. Older versions of DBD::ODBC assumed that the binding type was 12 (SQL_VARCHAR). Newer versions default to 0, which means that DBD::ODBC will attempt to query the driver via SQLDescribeParam to determine the correct type. If the driver doesnt support SQLDescribeParam, then DBD::ODBC falls back to using SQL_VARCHAR as the default, unless overridden by bind_param()

odbc_force_rebind

This is to handle special cases, especially when using multiple result sets. Set this before execute to "force" DBD::ODBC to re-obtain the result sets number of columns and column types for each execute. Especially useful for calling stored procedures which may return different result sets each execute. The only performance penalty is during execute(), but I didnt want to incur that penalty for all circumstances. It is probably fairly rare that this occurs. This attribute will be automatically set when multiple result sets are triggered. Most people shouldnt have to worry about this.

odbc_async_exec

Allow asynchronous execution of queries. Right now, this causes a spin-loop (with a small "sleep") until the SQL is complete. This is useful, however, if you want the error handling and asynchronous messages (see the err_handler) below. See t/20SQLServer.t for an example of this.

odbc_exec_direct

Force DBD::ODBC to use SQLExecDirect instead of SQLPrepare() then SQLExecute. There are drivers that only support SQLExecDirect and the DBD::ODBC do() override doesnt allow returning result sets. Therefore, the way to do this now is to set the attributed odbc_exec_direct. There are currently two ways to get this: $dbh->prepare($sql, { odbc_exec_direct => 1}); and $dbh->{odbc_exec_direct} = 1; When $dbh->prepare() is called with the attribute "ExecDirect" set to a non-zero value dbd_st_prepare do NOT call SQLPrepare, but set the sth flag odbc_exec_direct to 1.

odbc_err_handler

Allow errors to be handled by the application. A call-back function supplied by the application to handle or ignore messages. If the error handler returns 0, the error is ignored, otherwise the error is passed through the normal DBI error handling structure(s).

This can also be used for procedures under MS SQL Server (Sybase too, probably) to obtain messages from system procedures such as DBCC. Check t/20SQLServer.t and mytest/testerrhandler.pl

The callback function takes three parameters: the SQLState, the ErrorMessage and the native server error.

odbc_SQL_ROWSET_SIZE

Here is the information from the original patch, however, Ive learned since from other sources that this could/has caused SQL Server to "lock up". Please use at your own risk!
SQL_ROWSET_SIZE attribute patch from Andrew Brown > There are only 2 additional lines allowing for the setting of > SQL_ROWSET_SIZE as db handle option. > > The purpose to my madness is simple. SqlServer (7 anyway) by default > supports only one select statement at once (using std ODBC cursors). > According to the SqlServer documentation you can alter the default setting > of > three values to force the use of server cursors - in which case multiple > selects are possible. > > The code change allows for: > $dbh->{SQL_ROWSET_SIZE} = 2; # Any value > 1 > > For this very purpose. > > The setting of SQL_ROWSET_SIZE only affects the extended fetch command as > far as I can work out and thus setting this option shouldnt affect > DBD::ODBC operations directly in any way. > > Andrew >

SQL_DRIVER_ODBC_VER

This, while available via get_info() is captured here. I may get rid of this as I only used it for debugging purposes.
odbc_cursortype (applies to connect only!)

This allows multiple concurrent statements on SQL*Server. In your connect, add { odbc_cursortype => 2 }. If you are using DBI > 1.41, you should also be able to use { odbc_cursortype => DBI::SQL_CURSOR_DYNAMIC } instead. For example:

my $dbh = DBI->connect("dbi:ODBC:$DSN", $user, $pass, { RaiseError => 1, odbc_cursortype => 2});
my $sth = $dbh->prepare("one statement");
my $sth2 = $dbh->prepare("two statement");
$sth->execute;
my @row;
while (@row = $sth->fetchrow_array) {
$sth2->execute($row[0]);
}

See t/20SqlServer.t for an example.

odbc_query_timeout

This allows the end user to set a timeout for queries on the ODBC side. After your connect, add { odbc_query_timeout => 30 } or set on the dbh before executing the statement. The default is 0, no timeout. Note that some drivers may not support this attribute.

See t/20SqlServer.t for an example.

odbc_has_unicode (applies to database handle only)
A read-only attribute signifying whether DBD::ODBC was built with the C macro WITH_UNICODE or not. A value of 1 indicates DBD::ODBC was built with WITH_UNICODE else the value returned is 0.

Building WITH_UNICODE affects columns and parameters which are SQL_C_WCHAR, SQL_WCHAR, SQL_WVARCHAR, and SQL_WLONGVARCHAR.

When odbc_has_unicode is 1, DBD::ODBC will:

bind columns the database declares as wide characters as SQL_Wxxx

This means that UNICODE data stored in these columns will be returned to Perl in UTF-8 and with the UTF8 flag set.
bind parameters the database declares as wide characters as SQL_Wxxx

Parameters bound where the database declares the parameter as being a wide character (or where the parameter type is explicitly set to a wide type - SQL_Wxxx) can be UTF8 in Perl and will be mapped to UTF16 before passing to the driver.
NOTE: You will need at least Perl 5.8.1 to use UNICODE with DBD::ODBC.

NOTE: At this time SQL statements are still treated as native encoding i.e. DBD::ODBC does not call SQLPrepareW with UNICODE strings. If you need a unicode constant in an SQL statement, you have to pass it as parameter or use SQL functions to convert your constant from native encoding to Unicode.

NOTE: Binding of unicode output parameters is coded but untested.

NOTE: When building DBD::ODBC on Windows ($^O eq MSWin32) the WITH_UNICODE macro is automatically added. To disable specify -nou as an argument to Makefile.PL (e.g. nmake Makefile.PL -nou). On non-Windows platforms the WITH_UNICODE macro is not enabled by default and to enable you need to specify the -u argument to Makefile.PL. Please bare in mind that some ODBC drivers do not support SQL_Wxxx columns or parameters.

UNICODE support in ODBC Drivers differs considerably. Please read the README.unicode file for further details.

odbc_version (applies to connect only!)

This was added prior to the move to ODBC 3.x to allow the caller to "force" ODBC 3.0 compatibility. Its probably not as useful now, but it allowed get_info and get_type_info to return correct/updated information that ODBC 2.x didnt permit/provide. Since DBD::ODBC is now 3.x, this can be used to force 2.x behavior via something like: my $dbh = DBI->connect("dbi:ODBC:$DSN", $user, $pass, { odbc_version => 2});

JDBC is a Perl 5 interface to Java JDBC (via Inline::Java).

SYNOPSIS

use JDBC;

JDBC->load_driver("org.apache.derby.jdbc.EmbeddedDriver");

my $con = JDBC->getConnection($url, "test", "test");

my $s = $con->createStatement();

$s->executeUpdate("create table foo (foo int, bar varchar(200), primary key (foo))");
$s->executeUpdate("insert into foo (foo, bar) values (42,notthis)");
$s->executeUpdate("insert into foo (foo, bar) values (43,notthat)");

my $rs = $s->executeQuery("select foo, bar from foo");
while ($rs->next) {
my $foo = $rs->getInt(1);
my $bar = $rs->getString(2);
print "row: foo=$foo, bar=$barn";
}

This JDBC module provides an interface to the Java java.sql.* and javax.sql.* JDBC APIs.

Need a Type 3 JDBC Driver for MS Access or SQL Server? Think RmiJdbc!
RmiJdbc project is a client/server JDBC Driver that relies on Java RMI.
All JDBC classes (like Connection, ResultSet, etc...) are distributed as RMI objects, so that you can distribute as you like the access to any database supporting the JDBC API.
In fact, RmiJdbc is just a bridge to allow remote access to JDBC drivers.
Why RmiJdbc?
- You develop a client/server application with databases on Windows (NT)? Use RmiJdbc along with the JDBC/ODBC Bridge, your Windows (NT) databases become remotely accessible in Java.
- You implement a JDBC Driver? Just implement the JDBC classes locally, dont bother with remote access!
- You need serializable JDBC classes? Here they are.
Enhancements:
- Add features/limitations/changes here

db2dot reverse engineers an existing database and produces an ER diagram in dot format.

The dot file can be fed through graphvizs dot to produce a pretty ER diagram. The diagram includes tables and relationships derived from db meta-data and foreign key constraints.

What format is the output?

It generates a dot file which can be turned into a diagram with the graphviz utility.

What database servers will it work with?

It has only been tested with MySQLs JDBC driver, but it uses only
generic java.sql.* classes so it should work with any JDBC driver which is
sufficiently advanced.

What license is the code released under?

db2dot is released under the GPL v2.0 license.

How do I build the source?

Run: ant build jar

What are the command line arguments?

The command line arguments may be in any order, the following are required:

driver=< JDBCDriver class >
url=< db connection url >
user=< db user name >
pass=< db password >

The following are optional:

+showRelations
+showColumns

JdbcTool project is a collection of command line utilities for making your life easy when working with Java JDBC databases. Included are:

jdbctool:

An interactive command line tool for executing SQL statements.

jdbcdump:

Dump the contents of a database as SQL statements into a file, like mysqldump.

jdbcload

Execute SQL statements from a file (the opposite of jdbcdump)

Currently, only HSQLDB is supported.

DBD::RAM is a DBI driver for files and data structures.

SYNOPSIS

use DBI;
my $dbh = DBI->connect(DBI:RAM:,usr,pwd,{RaiseError=>1});
$dbh->func({
table_name => my_phrases,
col_names => id,phrase,
data_type => PIPE,
data_source => [ ],
}, import );
print $dbh->selectcol_arrayref(qq[
SELECT phrase FROM my_phrases WHERE id = 1
])->[0];
__END__
1 | Hello, New World
2 | Some other Phrase

This sample creates a database table from data, uses SQL to make a selection from the database and prints out the results. While this table is in-memory only and uses pipe "delimited" formating, many other options are available including local and remote file access and many different data formats.

DBD::RAM allows you to import almost any type of Perl data structure into an in-memory table and then use DBI and SQL to access and modify it. It also allows direct access to almost any kind of file, supporting SQL manipulation of the file without converting the file out of its native format.

The module allows you to prototype a database without having an rdbms system or other database engine and can operate either with or without creating or reading disk files. If you do use disk files, they may, in most cases, either be local files or any remote file accessible via HTTP or FTP.

SQLiteJDBC is a JDBC driver for SQLite which is written as a Java JNI layer over the SQLite 3.3.x API.

SQLiteJDBC supports the most commonly used features of JDBC that can be efficiently implemented on top of SQLite. Only a single native JNI library is required, and SQLite is compiled in.

Binaries are provided for Linux, Mac OS X, and Windows.
