NAME

Eve::PgSql - the PostgreSQL factory.

SYNOPSIS

    use Eve::PgSql;

    # Construct a factory instance
    my $pgsql = Eve::PgSql->new(
        database => $database,
        host => $host,
        port => $port,
        user => $user,
        password => $password,
        schema => $schema);

    # Create a function instance
    my $foo = $pgsql->get_function(
        name => 'foo',
        input_list => [
            {'bar' => $pgsql->get_bigint()},
            {'foo' => $pgsql->get_smallint()}],
        output_list => [
            {'baz' => $pgsql->get_text()},
            {'bam' => $pgsql->get_timestamp_with_timezome()}]);

DESCRIPTION

Eve::PgSql is a factory providing services to interact with PostgreSQL databases and common dependencies between these services.

Constructor arguments

database
host
port
user
password
schema

By default all arguments are undef so the database adapter will attempt to use standard PostgreSQL environment variables.

METHODS

init()

get_connection()

A PostgreSQL connection lazy loader service.

get_function()

A PostgreSQL stored function prototype service.

Arguments

name

a stored function name

input_list

an optional list of input parameters, each of which is specified as a structure like

    {'parameter_name' => $parameter_type}

where the $parameter_type is a Eve::PgSqlType derivative.

output_list

an optional list of output parameters specified, just like the input_list argument.

get_bigint()

A PostgreSQL bigint type lazy loader service.

get_boolean()

A PostgreSQL boolean type lazy loader service.

get_double()

A PostgreSQL double precision floating point type lazy loader service.

get_double_array()

A PostgreSQL double precision array type lazy loader service.

get_geometry()

A PostGIS geometry type lazy loader service.

get_integer()

A PostgreSQL integer type lazy loader service.

get_integer_array()

A PostgreSQL integer array type lazy loader service.

get_interval()

A PostgreSQL interval type lazy loader service.

get_smallint()

A PostgreSQL smallint type lazy loader service.

get_text()

A PostgreSQL text type lazy loader service.

get_timestamp_with_time_zone()

A PostgreSQL timestamp with time zone type lazy loader service.

get_timestamp_without_time_zone()

A PostgreSQL timestamp without time zone type lazy loader service.

get_array()

A PostgreSQL array type lazy loader service.
