Hibernate Check Annotation
Yes it is possible if @Check is used at class level like this:
@Entity@Check(constraints = "COL_A IS NULL OR (COL_B IS NOT NULL and COL_C IS NOT NULL)")public class Sample { @Column(name = "COL_A") private Long a; @Column(name = "COL_B") private Long b; @Column(name = "COL_C") private Long c;}(Note that I rewrote your condition using @jarlh comment.). The constraints clause of @Check annotation needs to refer to the name attribute of @Column (it must be pure SQL).
@Check annotation needs to be at class level because of a Hibernate bug.
Use next annotation at Class level to check all three columns, e.g.:
@Check(constraints = "COL_A >= 15 AND COL_B < 200 AND COL_C > 100")
being COL_A, COL_B and COL_C the column names to be checked
Do not check nullable columns. @NotNull is preferred over @Check.
