CallSp
A stored procedures wrapper.
Installation
Add this line to your application's Gemfile:
gem 'call_sp', '~> 0.0.3'
And then execute:
$ bundle
Or install it yourself as:
$ gem install call_sp
Usage
Suppose your stored procedures are
CREATE OR REPLACE FUNCTION say_my_name(_name text) RETURNS TEXT AS $$
BEGIN
RETURN _name;
END;
$$ LANGUAGE plpgsql;
CREATE OR REPLACE FUNCTION sp.show_names() RETURNS TABLE (id integer, name varchar, age numeric) AS $$
BEGIN
RETURN QUERY SELECT * FROM "public"."names";
END;
$$ LANGUAGE plpgsql;
CREATE OR REPLACE FUNCTION sp.drop_teenagers() RETURNS VOID AS $$
BEGIN
DELETE FROM "public"."names" WHERE age < 20;
END;
$$ LANGUAGE plpgsql;
Just include CallSp module into your own class and will describe the stored procedures
class SpClass
include ::CallSp
procedure :my_name, { as: :say_my_name, mode: :fetch_sp_val }
procedure :show_names, { schema: :sp, mode: :fetch_sp }
procedure :drop_teenagers, { schema: :sp, mode: :execute_sp }
end
After that module will create a methods my_name, show_names, drop_teenagers and you can call them with parameters of stored procedure
SpClass.my_name(['John'])
SpClass.show_names([], { conditions: ["age > ?", 20], order: "age DESC" }).each do |row|
p row
end
SpClass.drop_teenagers()
