问题 I have a User entity with skills property as a type List. I want to query the User table against a list of skills in such a way that if all the skills are present in skill column then only a match is found unless no. I have used JPQL for this but it matches each element in the list one by one using the IN clause. User Class @Entity(name = "App_User") //table name "user" is not allowed in postgres public class User { @Id @GeneratedValue(generator = "UUID") @GenericGenerator(name = "UUID",

问题 I'm trying to retrieve data out of a legacy database. The column in the table is defined as a DECIMAL(13,0) containing account numbers. The column data type cannot be changed as it will have a major impact on the legacy system. Essentially all programs using the table need to be changed and then recompiled which is not an option. We have a requirement to find all records where the account number contains a value, for example the user could search for 12345 and all accounts with an account
