Q: How to use an ''if '' statement to make an condition while creating a table in plsql or is it possible to do the same in mysql? I want that the column could accept only Latin characters, how should I code? What do you suggest?
For example( in MySQL):
Create table employees_info(
employee_id int not null auto_increment,
first_name varchar(30) not null,
primary key(employee_id));

-- here I tried to use a 'check' clause but I  guess I could not use it correctly

I want that the column first_name could able to accept only Latin char;
