mysql批量插入

Posted 2021-01-17 北骁蚁

有多种方式

其中效率高 要求低的方式 是 把sql拼接出来 后一次性commit；

eg:

public int insertBatch(List<PeccDetailModel> list) {
    return super.insert("com.hshc.web.pec.dao.PeccDetailDao.insertBatch",list);
}

<insert id="insertBatch">

    insert ignore into table_
    (
    id, pecc_id,
    pecc_no,
    plate_no,
    infomation_code,
    pecc_time,
    pecc_addr,
    pecc_reason,
    pecc_amount,
    status,
    department,
    pecc_score,
    pecc_code,
    violation_code,
    archive_no,

    category, late_fees,
    basis_punishment,
    illegal_entry,
