How to add date in mysql database from Hibernate/Spring Jpa

Question

I use spring boot, and I want to add 1 year to a specific column in mysql database

String queryRecherche = "UPDATE myTable t SET t.dateDebut = DATE_ADD(t.dateDebut, INTERVAL 1 YEAR) WHERE.id = 3 ";
Query query = em.createQuery(queryRecherche);;
query.executeUpdate();

But I get the folowing error:

org.hibernate.query.sqm.ParsingException: line 1:66 no viable alternative at input 'DATE_ADD(t.dateDebut,INTERVAL1'

Have you please any suggestions to do this.

Answer 1

You're using Hibernate 6 (I can tell by the error message), so the correct HQL syntax to use is:

UPDATE MyEntity t SET t.dateDebut = t.dateDebut + 1 year WHERE t.id = 3

You had three errors in your query:

1. You referred to the name of a table instead of the name of an entity class in the UPDATE clause.
2. You used the unportable MySQL DATE_ADD function instead of the portable HQL date/time arithmetic described here .
3. The syntax of your WHERE clause was garbled.

Perhaps you meant for this to be a native SQL query, in which case you called the wrong method of Session . But there's no need to use native SQL for the above query. As you can see, HQL is perfectly capable of expressing that query.

Answer 2

You can use SQL directly, via createNativeQuery, or register a new function as shown in this example to call it from HQL
