Someone help me to understand the method GetParentRows() of the DataRow object.
The idea of a relational database is that a child row will have only ONE PARENT; hence the GetParentRow() method of the DataRow object. I cannot for the life of me come up with a good example of why GetParentRows() is needed. A One-to-Many relationship will have only one parent. A Many-to- Many relationship has some intermediate table (i.e. Person- >PersonAddressRelations->Address) so the relationships amongst all tables is still a one parent for a given child. To me it really just gives another way to get at rows based on how you compose the DataRelation object; which basically boils down to a hacked version of a “true” child relationship the developer wants to compose. Can someone help me understand the GetParentRows() method and an example of why its needed.
