举例把数据库长度设为一个小值16 FieldSchema(namequestion, dtypeDataType.VARCHAR, auto_idFalse, max_length16)
再把数据缩到只有一行 测试结果插入成功
line contents is : 你好呀你好 and length is 5 Batches: 100%|█████████████████████████████████████████████████████████████████████████████████████████████████████████████| 1/1 [00:0100:00, 1.02s/it] index handle result: Status(code0, message) insert result: (insert count: 1, delete count: 0, upsert count: 0, timestamp: 449735609509740549, success count: 1, err count: 0)
再增加一点文字长度 就报错了
