A DDL constraint.

Constraint definitions can be used in DDL statements in order to specify the constraint, or in some DML statements that reference a given constraint.

Example: 


// Assuming import static org.jooq.impl.DSL.*;

using(configuration)
   .alterTable(ACTOR)
   .add(constraint("actor_unique_name")
       .unique(ACTOR.FIRST_NAME, ACTOR.LAST_NAME))
   .execute();

Instances can be created using DSL#constraint(Name) and overloads.
