SYNOPSIS
DESCRIPTION
This module provides a subclass of DBIx::SearchBuilder::Handle that compensates for some of the idiosyncrasies of Postgres.METHODS
Connect
Connect takes a hashref and passes it off to SUPER::Connect; Forces the timezone to GMT it returns a database handle.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.In case of insert failure, returns a Class::ReturnValue object preloaded with error info.
InsertQueryString
Postgres sepcific overriding method for ``InsertQueryString'' in DBIx::SearchBuilder::Handle.IdSequenceName TABLE
Takes a TABLE name and returns the name of the sequence of the primary key for that table.BinarySafeBLOBs
Return undef, as no current version of postgres supports binary-safe blobsApplyLimits STATEMENTREF ROWS_PER_PAGE FIRST_ROW
takes an SQL SELECT statement and massages it to return ROWS_PER_PAGE starting with FIRST_ROW;_MakeClauseCaseInsensitive FIELD OPERATOR VALUE
Takes a field, operator and value. performs the magic necessary to make your database treat this clause as case insensitive.Returns a FIELD OPERATOR VALUE triple.
DistinctQuery STATEMENTREF
takes an incomplete SQL SELECT statement and massages it to return a DISTINCT result set.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.In Pg time and timestamp data types may be ``with time zone'' or ``without time zone''. So if Field argument is timestamp ``with time zone'' then From argument is not required and is useless. Otherwise From argument identifies time zone of the Field argument that is ``without time zone''.
For consistency with other DBs use timestamp columns without time zones and provide From argument.
