List of addJoinedAttribute() Examples

Examples of addJoinedAttribute()

org.eclipse.persistence.queries.ObjectLevelReadQuery.addJoinedAttribute()
PUBLIC: Specify the one-to-one mapped attribute to be join fetched in this query. The query will join the object(s) being read with the one-to-one attribute, this allows all of the data required for the object(s) to be read in a single query instead of (n) queries. This should be used when the application knows that it requires the part for all of the objects being read.
Note: This cannot be used for objects where it is possible not to have a part, as these objects will be omitted from the result set, unless an outer join is used through passing and expression using "getAllowingNull". To join fetch collection relationships use the addJoinedAttribute(Expression) using "anyOf" ot "anyOfAllowingNone".
Example: query.addJoinedAttribute("address") @see #addJoinedAttribute(Expression) @see ReadAllQuery#addBatchReadAttribute(Expression)
