如果我有以下架构:
EMPLOYEE (Fname, Minit, Lname, Ssn, Bdate, Address, Sex, Salary,
Super_ssn, Dno)
DEPARTMENT (Dname, Dnumber, Mgr_ssn, Mgr_start_date)
DEPT_LOCATIONS(Dnumber, Dlocation)
PROJECT(Pname, Pnumber, Plocation, Dnum)
WORKS_ON(Essn, Pno, Hours)
DEPENDENT(Essn, Dependent_name, Sex, Bdate, Relationship)
我希望Account Bob检索EMPLOYEE和DEPARTMENT的所有属性 除了Salary,Mgr_ssn和Mgr_start_date,我该怎么做?
