Hi Cur,
The JPA unique constraint allows multiple column names. See the attached screenshot for an example, so create the
following elements in an annotations model:
- annotated eclass
- orm annotation
- entity
- table
- uniqueconstraint with multiple column names
the example from the attached screenshort gives the following java code:
@Entity(name = "Bz423155_Main423155")
@Table(uniqueConstraints = { @UniqueConstraint(columnNames = { "abc", "def" }, name = "my unique constraint") })
public class Main423155 {
