Hello,

I'm creating a data model using MySQL Workbench. I cannot find a way how to add a multi-column unique constraint to a table according to the following create table command:

CREATE TABLE Persons (
ID int NOT NULL,
LastName varchar(255) NOT NULL,
FirstName varchar(255),
Age int,
CONSTRAINT UC_Person UNIQUE (ID,LastName)
).

Could somebody give me a tip on how to do this?

Kind regards,
Radek
