I am new to Hybris. My Requirement is to select all customers who have not left comments. I found that Comments have an author field and that I joined two fields of Customers and Comments. Also, I find out that Comment has a comment field which is a collection of comments. The problem is that I can't access to comment field to check if is it null or not.
SELECT * FROM {comment AS ct JOIN customer AS cr ON {ct:author}={cr:pk}} WHERE
{ct:comment} IS NOT NULL
the exception that hac gives
Exception message: cannot search unknown field 'TableField(name='p_comment',langPK='null',type=comment)
it says there is no comment field
Comment model has text fields, I can't see Comment field on it. Use below query:
SELECT * FROM {comment AS ct JOIN customer AS cr ON {ct:author}={cr:pk}}
WHERE {ct:text} IS NOT NULL
