Anyone know of places where we document ColumnTransformer read-fragment handling as qualifying columns other than the column the transformer is attached to? E.g., consider: @Column( name="dob" ) @ColumnTransformer( read="SYSDATE - dob / 365", ... ) public int getAge() { ... } Currently, Hibernate will try to qualify both "SYSDATE" and "dob" with table alias. The simple fix is to simply limit the qualification to the column that the transformer is attached to ("dob"). Just want to make sure that we do not document anywhere that multiple column references will all be replaced. E.g. (contrived): @Column( name="dob" ) @ColumnTransformer( read="(SYSDATE - dob / 365) + offset", ... ) public int getAge() { ... } The question is whether both "dob" and "offset" columns will get qualified. Allowing this is much more involved, requiring that we somehow allow configuration of all the referenced columns that should be qualified (which has its own set of difficulties when it comes to multi-table structures). I propose the simple solution, unless there are any objections
