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