使用MySQL的“insert ... on duplicate key update”实现存在即更新操作,简化数据入库操作([issues#2])。 在开启allowMultiQueries=true(默认不会开启)情况下支持upsertByExample,upsertByExampleSelective操作,但强力建议不要使用(需保证团队没有使用statement提交sql,否则会存在sql注入风险)([issues#2])。
集成选装件InsertBatchSomeColumn做批量插入,实体类为null的字段,在生成批量插入SQL语句中会产生null值 重现步骤(如果有就写完整) 产生的sql语句如: insert into(id,name,age) values(1,null,2) 而不是insert into(id,age) values(1,2) 报错信息
