添加数据判断是否存在存在不添加，或存在更新
-- 1\添加数据首先判断数据库中该用户是否存在，如果存在则不进行添加
INSERT INTO dj_employee (GD_employeeId,employeeid,employeename,password,sex,mobile,factoryId,user_id)
select #{id},#{employeeid},#{employeename},#{employeeid},#{sex},#{mobile},#{factoryid},#{USER_ID}
WHERE NOT EXISTS (
SELECT 1 FROM dj_employee WHERE employeeid = #{employeeid} and IsDelete = 0
)
INSERT INTO dj_EmpRoleRight (empId,deptId,factoryId)
select #{employeeid},(select top 1 deptid from dj_pdept where remark=#{deptid} and factoryId=#{factoryid}),#{factoryid}
WHERE NOT EXISTS (
SELECT 1 FROM dj_EmpRoleRight WHERE empId = #{employeeid}
)
---2、如果表中数据存在则进行更新，如果不存在则进行添加
IF EXISTS (SELECT 1 FROM dj_employee WHERE employeeid = '特定employee_id')
UPDATE dj_employee
SET employeename = '新员工名'
WHERE employeeid = '特定employee_id';
ELSE
INSERT INTO dj_employee (employeeid, employeename)
VALUES ('特定employee_id', '新员工名');
