-- =====================================================
|

-- =====================================================
|
||
-- 1. 新增表: lottery_probability_segment (概率区间配置表)
|
||
-- 用途: 实现平均分配，防止奖项扎堆
|

-- 新增字段: activity_id, batch_no, points_cost

-- =====================================================
|

-- 检查并添加 activity_id 字段

-- 5. 卡片数据生成说明（lottery_card 表）
|
||
-- =====================================================
|
||
/*
|
||
卡片需要根据奖项配置批量生成，每个奖项对应多张卡片。
|
||
卡片数量：
|
||
- 海南省(award_id=1): 4张
|
||
- 海口(award_id=2): 3张, 三亚: 3张, 三沙: 3张, 儋州: 3张 = 12张
|
||
- 五指山~东方(award_id=6~10): 每个8张 = 40张
|
||
- 白沙~陵水(award_id=11~16): 每个10张 = 60张
|
||
- 定安~临高(award_id=17~20): 每个25张 = 100张
|
||
- 阳光普照(award_id=21): 99784张
|
||
|
||
总计: 4 + 12 + 40 + 60 + 100 + 99784 = 100000张
|
||
|
||
生成卡片的存储过程示例（可选）:
|
||
DELIMITER //
|
||
CREATE PROCEDURE generate_lottery_cards(IN p_award_id BIGINT, IN p_count INT, IN p_prefix VARCHAR(10))
|
||
BEGIN
|
||
DECLARE i INT DEFAULT 0;
|
||
WHILE i < p_count DO
|
||
INSERT INTO lottery_card (card_no, award_id, status, create_time)
|
||
VALUES (CONCAT(p_prefix, LPAD(i+1, 6, '0')), p_award_id, 0, NOW());
|
||
SET i = i + 1;
|
||
END WHILE;
|
||
END //
|
||
DELIMITER ;
|
||
|
||
-- 调用示例:
|
||
-- CALL generate_lottery_cards(1, 4, 'HN'); -- 海南省 4张
|
||
-- CALL generate_lottery_cards(2, 3, 'HK'); -- 海口 3张
|
