I want some mycoulmns in the JPA unit so that I take the value from the database during the inserts / updates, i.e. from Oracle sys_context, trust me Is the temporary annotation of JPA's included / timestamps generated during the updating / updating, is there any way that I can make a custom annotation somewhat current or provide some default values during the insert / update, If you can face this situation then nobody can give a hint.
I assume some code in the JPA unit from the database during the inserts / updates

@ Entity public class antenna {@Id Public Integer ID; @ Generated (Generation Time. Alway) @column (insertable = false, updateable = false) public string longitude; @ Generated (GenerationTime.INSERT) @column (insertable = false) public string latitude; }Comment your property as a
@generated, to ensure that your entry or updating ability is conflicts with the generation strategy you have selected Does not. When theGenerationTime.INSERTis selected, then there should be no attributable columns, when theGenerationTime.ALWAYSis selected, the inclusionable and neither the updated columns are included. should be there.
@Versionproperties can not be made with the@Generated (INSERT)design, it's eithereverorAlways.
