-- =============================================================
-- Contacts: support multiple mobile numbers (a person may have several)
-- Tables:
--   1) yz_backend_crm_entity_contact : contacts of clue / business / project
--   2) yz_backend_erp_contact        : global address book contacts
--   3) yz_backend_contact_company    : company contacts (customers/suppliers),
--      shared by project contact picker / address book / customer-supplier
--      conversion. This one was missed before: without the column any SELECT
--      fails and contact lists show as empty. Run this script manually
--      (server-side auto-migration has been removed).
-- All tables get a new column `mobiles` (TEXT, JSON array, max 5).
-- The old `mobile` / `phone` column keeps the FIRST number for backward
-- compatibility (list display, phone-based dedupe on sync), and existing
-- single numbers are backfilled into `mobiles`.
-- Run: mysql -h<host> -P<port> -u<user> -p <db> < alter_contact_mobiles.sql
--      (idempotent: existing columns are skipped, safe to re-run)
-- NOTE: keep this file ASCII-only; piping through some shells mangles non-ASCII.
-- =============================================================

-- 1) clue / business / project contacts
-- idempotent: ALTER only runs when the column is missing (no 1060 on re-run)
