  , TO_DATE ('2018/07/11','yyyy/mm/dd')
  , '9020.00', '2324.21', '20.00', 'E1'
  , 'Bassi', 'B1', 'Brand One', '123.00'
  , 'Type1', 'T One', '500.00', '123.00'
  , '555.00', 'D1' );

Answer 1

您已经在表中定义了EmployeeID int ，然后尝试将值'E1'插入该列。

Answer 2

I would strongly advise that you write your inserts more like this:

insert into WeeklySaleReport (ReportID, StartDate, EndDate, SaleAmount, ComRate, ComAmount,
                              EmployeeID, EName, BrandID, BName, BSaleAmount,
                              TypeID, TName, TSaleAmount, ESaleAmount, EBonus)
     values 'R1',                   -- ReportID
             DATE '2018-06-16',     -- StartDate
             DATE '2018-07-11',     -- EndDate
             9020.00,               -- SaleAmount
             2324.21,               -- ComRate
             20.00,                 -- ComAmount
             'E1'                   -- EmployeeId
    ---------^ ERROR
             'Bassi',               -- EName
             'B1',                  -- BrandId
             'Brand One',           -- BName
             123.00,                -- BSaleAmount
             'Type1',               -- TypeId
             'T One',               -- TName
             500.00,                -- TSaleAmount
             123.00,                -- ESaleAmount
             555.00,                -- Bonus
             'D1'                   -- DepartmentId
            );

Notes:

• List the columns in the update. Here, I've also added them as comments so you and others can follow what is going where.
• EmployeeId is obviously an error.
• Oracle recommends using VARCHAR2() rather than VARCHAR() for strings.
• Know your types! Don't put single quotes around numeric constants. It is misleading.
• Use the DATE keyword. It is ANSI standard and easier to read.

And I just learned something. The DepartmentId declaration is valid in Oracle, even though it does not have a type. Here is a SQL Fiddle. Most databases require the type definition in the table. However, I still don't know if the value is valid, because the type is not clear in the question.
