I’m trying to switch boolean field using the following hql:
update Entity e set e.booleanField = not e.booleanField where e.id = ?1;
Unfortunately “QuerySyntaxException: unexpected token: not near…” was thrown.
My question is: is there some unary operator for hibernate that supports such expression? Or any well known trick?
sql supports such queries (postgresql):
update entity_table set booleanField = not(booleanField);
I would just use a native SQL query for this.
