        LastName varchar(24),
        Email varchar(48),
        PhoneNumber varchar(12),
        HotelID integer
        PRIMARY KEY (EmployeeID),

    INSERT INTO Employee VALUES (1, ‘James’, ‘Jenkins’, ‘jj@gmail.com’, ’0412181111’, 1);
    INSERT INTO Employee VALUES (22, ‘Roy’, ‘Bond’, ‘jb@gmail.com’, ‘0418246192’, 1);

Error: "psql:employee:1: ERROR: table "employee" does not exist"

What is the way that the error can be fixed?

Answer 1

Your create statement has a comma(,) missing before declaring the primary key. Therefore the table is not getting created. This this:

CREATE TABLE Employee
(   EmployeeID integer,
FirstName varchar(24),
LastName varchar(24),
Email varchar(48),
PhoneNumber varchar(12),
HotelID integer,
PRIMARY KEY (EmployeeID),
FOREIGN KEY (HotelID) REFERENCES Hotel
);

Answer 2

The table Employee might not be already created in your database when you are trying to run above snippet. Always have an IF EXISTS check before dropping a table or stored procedure or function.

Your drop query should be.

drop table if exists `Employee`;
