如何为新的JPA @ElementCollection编写SQL DDL查询

Question

I have done a code change in a domain class(JPA). I added an ElementCollection to an entity:

@ElementCollection(targetClass = String.class)
@CollectionTable(name = "T_NETWORK_STATE", joinColumns = {@JoinColumn(name = "NETWORK_ID")})
@Column(name = "STATE")
private Set<String> states = new HashSet<>();

Now I want to write a flyway update db script for this change. I need the SQL DDL for the table T_NETWORK_STATE.

I am new to writing sql queries. any help will be appreciated!

Answer 1

CREATE TABLE T_NETWORK_STATE (
  NETWORK_ID INT,
  STATE VARCHAR(100),
  UNIQUE INDEX (NETWORK_ID, STATE),
  FOREIGN KEY (NETWORK_ID) REFERENCES NETWORK(NETWORK_ID)
);
