dataClass.all( )

dataClass.all( )  


 

The dataClass.all( ) method queries the datastore to find all the entities related to the dataclass and returns them as an entity selection.

The entities are returned in the default order, which is intially the order in which they were created. Note however that, if entities have been deleted and new ones added, the default order does not reflect the creation order anymore.

If no corresponding entity is found, an empty entity selection is returned.

Lazy loading is applied.

Example  

 C_OBJECT($allEmp)
 $allEmp:=ds.Employee.all()
