Interface Constraint

  • All Superinterfaces:
    FieldOrConstraint, Named, QueryPart, java.io.Serializable
    All Known Subinterfaces:
    ConstraintFinalStep, ConstraintForeignKeyOnStep, ConstraintTypeStep
    public interface Constraint
extends FieldOrConstraint
    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.
