mybatis一次执行多条SQL语句

Posted 2020-11-06 wujh88

数据库表中有的冗余字段需要修改，这就要修改多个表中的信息，在mybatis中如何实现一个mapper方法？

1、在jdbc路径中添加 allowMultiQueries=true

jdbc.jdbcUrl=jdbc:mysql://127.0.0.1:3306/account?useUnicode=true&characterEncoding=utf8&allowMultiQueries=true

2、mapper方法体内部直接写多个sql即可：

<update id="updateComName" parameterType="com..core.model.BaCompany" >
    update ba_company
    set company_name = #{companyName,jdbcType=VARCHAR},
    upd_time = #{updTime,jdbcType=TIMESTAMP},
    upd_user = #{updUser,jdbcType=VARCHAR}
    where company_id = #{companyId,jdbcType=VARCHAR};

    update ba_member
    set company_name = #{companyName,jdbcType=VARCHAR},
         upd_time = #{updTime,jdbcType=TIMESTAMP},
         upd_user = #{updUser,jdbcType=VARCHAR}
    where company_id = #{companyId,jdbcType=VARCHAR};

    update ba_account
    set company_name = #{companyName,jdbcType=VARCHAR},
      upd_time = #{updTime,jdbcType=TIMESTAMP},
      upd_user = #{updUser,jdbcType=VARCHAR}
    where company_id = #{companyId,jdbcType=VARCHAR}
  </update>
