CrudRepository.deleteAll() causes InvalidDataAccessResourceUsageException during testing - spring

Question

I'm testing a Spring Boot CrudRepository interface. The find methods work fine. However if I try to delete something, I get an exception.
For example I have the following:
#Test
public void testDelete()
{
generateTestData.saveCustomersWithoutOrders();
customerRepository.deleteAll();
}
This results in this stack trace:
org.springframework.dao.InvalidDataAccessResourceUsageException: could not prepare statement; SQL [select orders0_.customer_id as customer3_0_0_, orders0_.id as id1_1_0_, orders0_.id as id1_1_1_, orders0_.amount as amount2_1_1_, orders0_.customer_id as customer3_1_1_ from order orders0_ where orders0_.customer_id=?]; nested exception is org.hibernate.exception.SQLGrammarException: could not prepare statement

Answer 1

I added an entity named Order for storing customer orders. Since order is a reserved word, it created problems. Adding #Table(name="orders") solved the problem.
