Answer 1

使用此查询

create view tblResult 
   select 
       tblEmployee.EMP_ID, tblEmployee.EMP_NAME, tblEmployee.EMP_MAIL, 
       tblProjectDetails.EMP_ProjectName, tblProjectDetails.EMP_ProjectDetails 
FROM
tblEmployee 
INNER JOIN 
    tblProjectDetails on tblEmployee.EMP_ID = tblProjectDetails.EMP_ID
