NAME¶
DBIx::SearchBuilder::Handle::Pg - A Postgres specific Handle object
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.
