1.mybtis的foreach标签,foreach元素的属性主要有 item,index,collection,open,separator,close。 通过迭代把对应元素的属性批量插入。 <insert id="batchInsert"> insert into day_time(daily_year,daily_month,daily_week,daily_date,use_num,types) values <foreach collection="list" item="item" separator=",...
在MyBatis的mapper XML文件中,你可以编写使用ON DUPLICATE KEY UPDATE的批量插入或更新语句。以下是一个示例: xml <insert id="batchInsertOrUpdate" parameterType="java.util.List"> INSERT INTO your_table_name (column1, column2, column3, ...) VALUES <foreach collection="list" item="item...
mybatis实现批量插入更新 -- ON DUPLICATE KEY UPDATE 必须保证有唯一索引,可以是主键索引或者组合索引 <insert id="insertOrUpdate" parameterType="java.util.List"> INSERT INTO indicators_template_detail_rep( id,indicators_name,indicators_id,dimension_name,dimension_id,...

(3) 相较于replace into(insert加强版,不存在时insert,存在时先delete后insert)虽然也能达到批量更新目的,但因为删除和添加需要重复维护索引,所以大批量比on duplicate key update性能要差,小量可忽略,自选为主。 foreach中()后面不要有空格,如果报错
