DynamicQueryEngineBaseCreateSubqueryConnectionClausesDelete Method

Produces a set of WHERE Clauses to use in the DELETE queries which have filters spanning multiple entities. It produces one clause if it finds the deleteTable on the PK side and then stops and it produces n clauses if it finds deleteTable on the FK side of n relations in relationsToWalk. If the deleteTable is on the PK side, it produces a clause: deleteTableAlias.PKField1 = deleteTable.PKField1 AND... (for each field in the PK 1 clause) If the deleteTable is on the FK side, it produces deleteTableAlias.Field1 = relatedEntityTable.Field1 AND ... clauses for each relation the table of the persistence info is in.
