Create the SQL code for each of the tables. Below I have attached an attempt of the SQL code for the first table but I keep getting errors. Could you fix that and provide the revisisd code. Additonally, when writing the code for the other tables write it in a similar format as the one I provided please and thank you.

CREATE TABLE EMPLOYEE$\_$xxx

$($SSN Number CHAR$(9)$ NOT NULL,

First Name VARCHAR$(15)$ NOT NULL,

Mid Name CHAR

Last Name VARCHAR$(15)$ NOT NULL,

Birtday DATE
