DBIx::SearchBuilder::Handle::Oracle(3pm) User Contributed Perl Documentation DBIx::SearchBuilder::Handle::Oracle(3pm)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:
