-- STEP 1: Hapus tabel jika sudah ada

-- STEP 2: Buat tabel project_chickins
CREATE TABLE IF NOT EXISTS project_chickins (
    id BIGSERIAL PRIMARY KEY,
    project_flock_kandang_id BIGINT NOT NULL,
    product_warehouse_id BIGINT NOT NULL,
    chick_in_date DATE NOT NULL,
    usage_qty NUMERIC(15, 3) NOT NULL,
    pending_usage_qty NUMERIC(15, 3) DEFAULT 0,
    notes TEXT,
    created_by BIGINT NOT NULL,
    created_at TIMESTAMPTZ DEFAULT now(),
    updated_at TIMESTAMPTZ DEFAULT now(),
    deleted_at TIMESTAMPTZ
);

-- STEP 3: FOREIGN KEYS
DO $$

    -- Relasi ke product_warehouses
    IF EXISTS (SELECT 1 FROM pg_tables WHERE tablename = 'product_warehouses') THEN
        ALTER TABLE project_chickins

-- STEP 4: INDEXES
CREATE INDEX IF NOT EXISTS idx_chickins_kandang_id ON project_chickins (project_flock_kandang_id);

CREATE INDEX IF NOT EXISTS idx_chickins_warehouse_id ON project_chickins (product_warehouse_id);

CREATE INDEX IF NOT EXISTS idx_chickins_created_by ON project_chickins (created_by);
