NAME

	 DBIx::SearchBuilder::Handle::Oracle - An oracle specific Handle object

SYNOPSIS

DESCRIPTION

       This module provides a subclass of DBIx::SearchBuilder::Handle that compensates for some of the idiosyncrasies of Oracle.

METHODS

   Connect PARAMHASH: Driver, Database, Host, User, Password
       Takes a paramhash and connects to your DBI datasource.

   BuildDSN
       Customized version of "BuildDSN" in DBIx::SearchBuilder::Handle method.

       Takes additional argument SID. Database argument used unless SID provided.  Two forms of DSN are generated depending on whether Host
       defined or not:

	   dbi:Oracle:sid=<SID>;host=...[;port=...]
	   dbi:Oracle:<SID>

       Read details in documentation for DBD::Oracle module.

   Insert
       Takes a table name as the first argument and assumes that the rest of the arguments are an array of key-value pairs to be inserted.

   InsertFromSelect
       Customization of "InsertFromSelect" in DBIx::SearchBuilder::Handle.

       Unlike other DBs Oracle needs:

       o   id generated from sequences for every new record.

       o   query wrapping in parens.

       NOTE that on Oracle there is a limitation on the query. Every column in the result should have unique name or alias, for example the
       following query would generate "ORA-00918: column ambiguously defined" error:

	   SELECT g.id, u.id FROM ...

       Solve with aliases:

	   SELECT g.id AS group_id, u.id AS user_id FROM ...

   KnowsBLOBs
       Returns 1 if the current database supports inserts of BLOBs automatically.  Returns undef if the current database must be informed of BLOBs
       for inserts.

   BLOBParams FIELD_NAME FIELD_TYPE
       Returns a hash ref for the bind_param call to identify BLOB types used by the current database for a particular column type.  The current
       Oracle implementation only supports ORA_CLOB types(112).

   ApplyLimits STATEMENTREF ROWS_PER_PAGE FIRST_ROW
       takes an SQL SELECT statement and massages it to return ROWS_PER_PAGE starting with FIRST_ROW;

   DistinctQuery STATEMENTREF
       takes an incomplete SQL SELECT statement and massages it to return a DISTINCT result set.

   BinarySafeBLOBs
       Return undef, as Oracle doesn't support binary-safe CLOBS

   DatabaseVersion
       Returns value of ORA_OCI constant, see "Constants" in DBI.

   SimpleDateTimeFunctions
       Returns hash reference with specific date time functions of this database for "DateTimeFunction" in DBIx::SearchBuilder::Handle.

   ConvertTimezoneFunction
       Custom implementation of "ConvertTimezoneFunction" in DBIx::SearchBuilder::Handle.

       Use the following query to get list of timezones:

	   SELECT tzname FROM v$timezone_names;

       Read Oracle's docs about timezone files:

NAME

       Apache::Session::Store::Oracle - Store persistent data in a Oracle database

SYNOPSIS

	use Apache::Session::Store::Oracle;

	my $store = new Apache::Session::Store::Oracle;

	$store->insert($ref);
	$store->update($ref);
	$store->materialize($ref);
	$store->remove($ref);

DESCRIPTION

       Apache::Session::Store::Oracle fulfills the storage interface of Apache::Session. Session data is stored in a Oracle database.

SCHEMA

       To use this module, you will need at least these columns in a table called 'sessions':

	id varchar2(32)     # or however long your session IDs are.
	a_session long

       To create this schema, you can execute this command using the sqlplus program:

	CREATE TABLE sessions (
	   id varchar2(32) not null primary key,
	   a_session long
	);

       If you use some other command, ensure that there is a unique index on the table's id column.

CONFIGURATION

       The module must know what datasource, username, and password to use when connecting to the database.  These values can be set using the
       options hash (see Apache::Session documentation).  The options are DataSource, UserName, and Password.

       Example:

	tie %hash, 'Apache::Session::Oracle', $id, {
	    DataSource => 'dbi:Oracle:database',
	    UserName   => 'database_user',
	    Password   => 'K00l'
	};

       Instead, you may pass in an already-opened DBI handle to your database.

	tie %hash, 'Apache::Session::Oracle', $id, {
	    Handle => $dbh
	};

       The last option is LongReadLen, which specifies the maximum size of the session object.	If not supplied, the default maximum size is 8 KB.
