In SQL how would I insert into a MAX count of another column

So I have this

INSERT INTO USER(id,name,employee_code,email) VALUES (3,john,(SELECT MAX(employee_code)+1 FROM USER),"john@example.com");

However this doesn’t work with the syntax… basically it’s like an autoincrement that I have to self build because the employee_code sometimes equals 0 for temporary employees so I need a command to take the max code in their and add one.

    Do away with the VALUES statement and use a select instead:

    INSERT INTO USER(id,name,employee_code,email)
    SELECT 3, 'john', MAX(employee_code)+1, "john@example.com"
    FROM USER
