  • mybatis执行批量更新batch update 的方法(oracle,mysql)

    有时候oracle的最后一个sql少个分号,要在end前面加上分号
     
    oracle和mysql数据库的批量update在mybatis中配置不太一样:
    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 = ${item.id} </foreach> </update>
    mysql数据库:
    mysql数据库采用一下写法即可执行,但是数据库连接必须配置:&allowMultiQueries=true
    例如:jdbc:mysql://192.168.1.236:3306/test?useUnicode=true&amp;characterEncoding=UTF-8&allowMultiQueries=true
    <update id="batchUpdate" parameterType="java.util.List"> <foreach collection="list" item="item" index="index" open="" close="" separator=";"> update test <set> test=${item.test}+1 </set> where id = ${item.id} </foreach> </update>
