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:
