-- ============================================================
-- Phase 1: Schema Expansion
-- Neue Enums, Felder, Multi-Value Tabellen, Owner-Tabellen
-- ============================================================

-- WICHTIG: ALTER TYPE ... ADD VALUE kann NICHT in einer Transaction laufen.
-- Diese Migration muss daher ausserhalb von BEGIN/COMMIT ausgefuehrt werden,
-- oder der ADD VALUE muss separat laufen.

-- --------------------------------------------------------
-- 1. Neue Enums erstellen
-- --------------------------------------------------------

CREATE TYPE "app_crm"."ContactSource" AS ENUM (
  'TRADE_FAIR', 'REFERRAL', 'WEBSITE', 'COLD_CALL',
  'IMPORT', 'BUSINESS_CARD', 'OTHER'
);

CREATE TYPE "app_crm"."EntityStatus" AS ENUM (
  'ACTIVE', 'INACTIVE', 'BLOCKED'
);

CREATE TYPE "app_crm"."CompanySize" AS ENUM (
  'SIZE_1_10', 'SIZE_11_50', 'SIZE_51_200', 'SIZE_201_500', 'SIZE_500_PLUS'
);

CREATE TYPE "app_crm"."OwnerRole" AS ENUM (
  'OWNER', 'MEMBER', 'WATCHER'
);

CREATE TYPE "app_crm"."LostReason" AS ENUM (
  'PRICE', 'TIMING', 'COMPETITOR', 'NO_NEED', 'OTHER'
);

CREATE TYPE "app_crm"."EmailType" AS ENUM (
  'WORK', 'PERSONAL', 'OTHER'
);

CREATE TYPE "app_crm"."PhoneType" AS ENUM (
  'OFFICE', 'MOBILE', 'FAX'
);

-- FOLLOWUP zum ActivityType Enum hinzufuegen (NICHT transaktionsfaehig!)
ALTER TYPE "app_crm"."ActivityType" ADD VALUE IF NOT EXISTS 'FOLLOWUP';

-- --------------------------------------------------------
-- 2. Neue Spalten auf contacts
-- --------------------------------------------------------

ALTER TABLE "app_crm"."contacts"
  ADD COLUMN "linkedin_url" VARCHAR(500),
  ADD COLUMN "birthday" TIMESTAMP(3),
  ADD COLUMN "source" "app_crm"."ContactSource",
  ADD COLUMN "department" VARCHAR(200),
  ADD COLUMN "status" "app_crm"."EntityStatus" NOT NULL DEFAULT 'ACTIVE';

-- --------------------------------------------------------
-- 3. Neue Spalten auf companies
-- --------------------------------------------------------

ALTER TABLE "app_crm"."companies"
  ADD COLUMN "vat_id" VARCHAR(50),
  ADD COLUMN "tax_id" VARCHAR(50),
  ADD COLUMN "trade_register_number" VARCHAR(100),
  ADD COLUMN "register_court" VARCHAR(200),
  ADD COLUMN "company_size" "app_crm"."CompanySize",
  ADD COLUMN "delivery_street" VARCHAR(200),
  ADD COLUMN "delivery_zip" VARCHAR(20),
  ADD COLUMN "delivery_city" VARCHAR(100),
  ADD COLUMN "delivery_country" VARCHAR(2),
  ADD COLUMN "status" "app_crm"."EntityStatus" NOT NULL DEFAULT 'ACTIVE',
  ADD COLUMN "data_enriched_at" TIMESTAMP(3),
  ADD COLUMN "data_enriched_source" VARCHAR(200);

-- --------------------------------------------------------
-- 4. Neue Spalten auf deals (Lost-Reason)
-- --------------------------------------------------------

ALTER TABLE "app_crm"."deals"
  ADD COLUMN "lost_reason" "app_crm"."LostReason",
  ADD COLUMN "lost_reason_text" TEXT;

-- --------------------------------------------------------
-- 5. Daten-Migration: isActive → status
-- --------------------------------------------------------

UPDATE "app_crm"."contacts"
  SET "status" = 'INACTIVE'
  WHERE "is_active" = false;

UPDATE "app_crm"."companies"
  SET "status" = 'INACTIVE'
  WHERE "is_active" = false;

-- --------------------------------------------------------
-- 6. Multi-Value: contact_emails Tabelle
