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 blobs

ApplyLimits 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.
