USE hzdyjs_xg;

-- 1. 修改现有批次表结构，增加目标条件字段（如果不存在）
ALTER TABLE xg_collection_batch 
ADD COLUMN IF NOT EXISTS target_grade VARCHAR(50) COMMENT '目标届别(如:2021,2022,2023)' AFTER batch_status,
ADD COLUMN IF NOT EXISTS target_college_ids TEXT COMMENT '目标学院ID列表(JSON格式)' AFTER target_grade,
ADD COLUMN IF NOT EXISTS target_major_ids TEXT COMMENT '目标专业ID列表(JSON格式)' AFTER target_college_ids,
ADD COLUMN IF NOT EXISTS target_class_ids TEXT COMMENT '目标班级ID列表(JSON格式)' AFTER target_major_ids,
ADD COLUMN IF NOT EXISTS remind_before_start INT DEFAULT 24 COMMENT '开始前提醒时间(小时)' AFTER target_class_ids,
ADD COLUMN IF NOT EXISTS remind_before_end INT DEFAULT 24 COMMENT '结束前提醒时间(小时)' AFTER remind_before_start,
ADD COLUMN IF NOT EXISTS auto_close TINYINT DEFAULT 1 COMMENT '是否自动关闭' AFTER remind_before_end,
ADD COLUMN IF NOT EXISTS notification_sent TINYINT DEFAULT 0 COMMENT '是否已发送通知' AFTER auto_close,
ADD COLUMN IF NOT EXISTS created_by_module VARCHAR(50) DEFAULT 'student_info' COMMENT '创建模块' AFTER notification_sent;

CREATE INDEX IF NOT EXISTS idx_xg_collection_batch_module ON xg_collection_batch(created_by_module);
CREATE INDEX IF NOT EXISTS idx_xg_student_info_last_batch ON xg_student_info(last_batch_id);
CREATE INDEX IF NOT EXISTS idx_xg_student_info_lock_status ON xg_student_info(info_lock_status);

-- 9. 插入一些测试数据
INSERT INTO xg_collection_batch (id, tenant_id, batch_code, batch_name, batch_type, academic_year, semester, batch_status, start_time, end_time, description, create_by, create_time, update_by, update_time, deleted) VALUES

(1745001000000000002, '000000', 'BATCH_2024_2', '2024-2025学年第二学期信息采集', 'annual', '2024-2025', '2', '1', '2025-02-15 00:00:00', '2025-03-15 23:59:59', '2024-2025学年第二学期学生信息采集工作', 1, NOW(), 1, NOW(), 0)
ON DUPLICATE KEY UPDATE 
    batch_name = VALUES(batch_name),
    description = VALUES(description),
    update_time = NOW();

-- 完成信息
SELECT 'Database tables created successfully!' as message;
