SYNOPSIS¶
DESCRIPTION¶
This module provides a subclass of Jifty::DBI::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, 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

Takes a TABLE name and returns the name of the sequence of the primary key for
that table.

current database for a particular column type. The current Postgres
implementation only supports BYTEA types.

takes an SQL SELECT statement and massages it to return ROWS_PER_PAGE starting
with FIRST_ROW;
_make_clause_case_insensitive column operator VALUE¶
Takes a column, operator and value. performs the magic necessary to make your
database treat this clause as case insensitive.

result set.
