mybatis批量插入时判断是否存在 如果存在就更新

 建立了一个唯一的约束 payroll_number，来判断是否重复 

 <insert id="insertStaffSalaryList" parameterType="java.util.List" useGeneratedKeys="true" keyProperty="id">
    insert into staff_salary

mybatis批量插入时判断是否存在 如果存在就忽略  

INSERT INTO staff_salary(user_id, approval_date, user_name, id_card) 
SELECT '491', '2010-01-10', '高某' , '6404251111112227'
FROM DUAL
WHERE NOT EXISTS(SELECT id FROM staff_salary WHERE approval_date = '2020-01-10' AND id_card ='6404251111112227' )

 先试了试单个数据的增加判断 关键词

insert into 表名 (列名) 

      （注意这里没有value） select 插入的值  

             from dual

                 where not exists(查询的数据用来判断唯一的条件)

      放上mybatis代码   注意 separator="union all"
