DBIx::SearchBuilder::HUsereContributed PDBIx::SearchBuilder::Handle::Oracle(3)

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:

       ·   id generated from sequences for every new record.

       ·   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:

	   http://download.oracle.com/docs/cd/B14117_01/server.101/b10749/ch4datetime.htm#i1006667
