Java之MyBatis 批量删除数据，两种方式（注解，XML）

Posted 2022-03-01 北芳科技

1、MyBatis之 XML 批量删除数据

public int deleteSysStudentStuIds(Long[] stuIds);

<delete id="deleteSysStudentStuIds" parameterType="String">
        delete from sys_student where stu_id in
        <foreach item="stuId" collection="array" open="(" separator="," close=")">
            #stuId
        </foreach>
</delete>

2、MyBatis之 注解 批量删除数据

@Delete("<script>
        delete from sys_student where stu_id in 
        <foreach collection='array' item='stuId' open='(' separator=',' close=')'>#stuId</foreach>
                  </script>")
        
void delete(Long[] stuIds);
