Next Table

To fully describe the properties CascadeUpdate and CascadeDelete there has to be placed another table element, which is referenced by the first table element.

If you need help please read Table selection again.

Important:

The options CascadeUpdate and CascadeDelete have to be enabled only at your first table, because this table (the first table) describes the main data source.

If some datasets are not used anymore, there referenced column does not have to exist at your 2^nd table.

Because the 2^nd table just contains data, which is only helpful or usable if the dataset of your first table still exists.

But if there is one more table ( table 3 ) which contains data referenced through the 2^nd table the options have to be enabled here ( table 2 ), too.

Warning:

Theoretically there is the possibility to create a circled reference.
