ALTER TABLE xg_collection_batch
|
|
ADD COLUMN target_grade VARCHAR(50) COMMENT '目标届别(如:2021,2022,2023)' AFTER target_scope,
|
|
ADD COLUMN target_college_ids TEXT COMMENT '目标学院ID列表(JSON格式)' AFTER target_grade,

UPDATE xg_collection_batch
|
|
SET created_by_module = 'student_info'
|
|
WHERE created_by_module IS NULL;
|
|
|
|
-- 3. 创建索引
|
|
CREATE INDEX idx_xg_collection_batch_grade ON xg_collection_batch(target_grade);
|
|
CREATE INDEX idx_xg_collection_batch_module ON xg_collection_batch(created_by_module);
