GildedRose-Refactoring-Kata/plpgsql/README.md

Requirements

You'll need:

• PostgreSQL database, version >= 11 because PROCEDURE keyword isn't supported before version 11
• OS user with local connection privilege to database on standard 5432 port

To use remote / local dockerized database, add --host --port --username parameters to plsql invocation.

Setup

In shell:

• create database: createdb gilded_rose
• create item table (structure): psql -d gilded_rose -f ./structure/create.sql
• load code into database: psql -d gilded_rose -f ./code/update_quality.sql

If you get this messageLINE 1: CREATE OR REPLACE PROCEDURE public.update_quality(), your PostgreSQL version may under 11, consider upgrading.

Interactive run

In shell:

• load test data into database: psql -d gilded_rose -f ./test/data/load.sql
• connect to CLI: psql -d gilded_rose
• check item state: SELECT * FROM item;
• execute item update: CALL update_quality();
• check item state: SELECT * FROM item;

Test

No test code provided, only a sample of test data TODO: [https://pgtap.org/](introduce TAP - xUnit for PL/pg SQL)
