CDT persistence - JoinColumn with referencedColumnName

This is a pretty old post - if you're having an issue setting up your data structure, I'd suggest creating a new post with context for what you're trying to do and what isn't working.

Also just a quick note - usually if you have a flat data structure you don't even use annotations in your CDT. Instead, I'd recommend setting up the table structure that you want directly in the database and then create your CDTs from the already created table.

Hi mikej117,

AFAIK After defining the relationship, need to click the Foreign Key icon for that field to further configure the relationship.(need to tick the checkbox "I know the name of the columns this field should use in the data base").Otherwise a random column name will be created in Data Base.

Please refer the below link for more info.

Have you tried something like this?

@JoinTable(name="FSA_REQUESTED_SYSTEM_ROLE_JOIN", joinColumns=@JoinColumn(name="REQUESTED_SYSTEM_ID"), inverseJoinColumns=@JoinColumn(name="ROLE_ID"))
