-- STEP 1: Hapus tabel jika sudah ada
DROP TABLE IF EXISTS project_chickins;

-- 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
BEGIN;

-- Relasi ke project_flock_kandangs
ALTER TABLE project_chickins
ADD CONSTRAINT fk_project_chickins_kandang FOREIGN KEY (project_flock_kandang_id) REFERENCES project_flock_kandangs (id) ON DELETE RESTRICT ON UPDATE CASCADE;

-- Relasi ke product_warehouses
ALTER TABLE project_chickins
ADD CONSTRAINT fk_project_chickins_warehouse FOREIGN KEY (product_warehouse_id) REFERENCES product_warehouses (id) ON DELETE CASCADE ON UPDATE CASCADE;

-- Relasi ke users
ALTER TABLE project_chickins
ADD CONSTRAINT fk_project_chickins_created_by FOREIGN KEY (created_by) REFERENCES users (id) ON DELETE RESTRICT ON UPDATE CASCADE;

COMMIT;

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

CREATE INDEX IF NOT EXISTS idx_chickins_warehouse_id ON project_chickins (product_warehouse_id)
WHERE
    deleted_at IS NULL;

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

-- Composite index for common queries
CREATE INDEX IF NOT EXISTS idx_chickins_kandang_deleted ON project_chickins (
    project_flock_kandang_id,
    deleted_at
);

-- Index for soft delete queries
CREATE INDEX IF NOT EXISTS idx_chickins_deleted_at ON project_chickins (deleted_at);
