mybatis 同时写多条sql

一、oracle数据

<delete id="delete" parameterType="upc.cbs.HtxxlrEntity">
begin 
  delete from PC_CBS_CONTRACT where contract_id = #{contract_id};
  delete from PC_CBS_UPLOAD_FILES where  contract_id = #{contract_id} and  filetype='合同附件';
  delete from PC_CBS_CONTRACT_TEAM where contract_id = #{contract_id};
 end;
</delete>

只需要添加begin 和 end; 每个sql语句用“；”结束

二、mysql

1、修改数据库连接参数加上allowMultiQueries=true，如：

hikariConfig.security.jdbcUrl=jdbc:mysql://xx.xx.xx:3306/xxxxx?characterEncoding=utf-8&autoReconnect=true&failOverReadOnly=false&allowMultiQueries=true
2、直接写多条语句，用“；”隔开即可

<delete id="delete" parameterType="upc.cbs.HtxxlrEntity">
  delete from PC_CBS_CONTRACT where contract_id = #{contract_id};
  delete from PC_CBS_UPLOAD_FILES where  contract_id = #{contract_id} and  filetype='合同附件';
  delete from PC_CBS_CONTRACT_TEAM where contract_id = #{contract_id};
</delete>

mysql需要修改数据连接添加allowMultiQueries=true属性；每个sql语句用“；”分开
