Mybatis批量操作

mac2022-06-30  96

一、批量更新

1.oracle数据库:

update id="batchUpdate" parameterType="java.util.List"> <foreach collection="list" item="item" index="index" open="begin" close="end;" separator=";"> update test <set> test=${item.test}+1 </set> where id = ${item.id} </foreach> </update>

2.mySql数据库

mysql数据库采用一下写法即可执行,但是数据库连接必须配置:&allowMultiQueries=true

例如:jdbc:mysql://192.168.1.236:3306/test?useUnicode=true&characterEncoding=UTF-8&allowMultiQueries=true

<update id="batchUpdate" parameterType="java.util.List"> <foreach collection="list" item="item" index="index" open="" close="" separator=";"> update test <set> test=${item.test}+1 </set> where id = ${item.id} </foreach> </update>
