It is impossible to set Constraint.NO_CONSTRAINT for a @JoinColumn in @JoinTable. It will generate a FK no matter what.
Error: Foreign key (FK3io8xbemymxv4bm5ccmh2ba8a:audience_sharing \[audience_group_id,provider_id])) must have same number of columns as the referenced primary key (audience_group \[audience_group_id])
I have tried all workaround but none works. The work arounds which applied the example below:
{code:java}@JoinColumn(name = "provider_id", referencedColumnName = "provider_id", foreignKey = @ForeignKey(value = Constraint.NO_CONSTRAINT){code}
{noformat}@JoinColumn(name = "provider_id", referencedColumnName = "provider_id", foreignKey = @ForeignKey(name = “none”, value = Constraint.NO_CONSTRAINT){noformat}
{noformat}@JoinTable(
foreignKey = @ForeignKey(value = Constraint.NO_CONSTRAINT)
){noformat}
Example:
{code:java}@ManyToMany(fetch = FetchType.LAZY, cascade = {CascadeType.PERSIST, CascadeType.MERGE, CascadeType.REFRESH, CascadeType.DETACH})
@JoinTable(
name = "sharing",
joinColumns = {
@JoinColumn(name = "audience_group_id", referencedColumnName = "audience_group_id"),
@JoinColumn(name = "provider_id", referencedColumnName = "provider_id", foreignKey = @ForeignKey(value = Constraint.NO_CONSTRAINT)),
},
inverseJoinColumns = @JoinColumn(name = "product_id")
)
@JsonManagedReference
private Set<Product> products = new HashSet<>(0);{code} |
