HasGenuinePersonRestrictions
Did the restrictions contain any clause that applied to the person part of the query (incluincludePersonRestriction and includePersonWithNoDMRestriction do not count as there are merely modifiers)

NeedComplexPrimaryKey
Does the contact+person query need a complex (both contact AND person) key? This is true in one special, but useful, case: A search purely on contact criteria, but with the ALL option on persons. Then, we cannot either EITHER contactId OR personID, but have to use both in combination.

SetJoin()
Set up the join between our person table and the parent contact. Special processing, see remarks!
Declaration
protected override PersonTableInfo SetJoin()Returns
| Type | Description |
|---|---|
| PersonTableInfo |
Overrides
Remarks
Dynamic person selection restrictions are a complicated puzzle. Basically, the only user-settable restrictions are on Interests, and such restrictions should cause a narrowing of the result set (exclude contact/person rows that do not match). However, the includePersonRestriction has special behaviour - it means 'keep whatever contacts you may have, but add persons if they exist'. That implies an OUTER and not an INNER join from contact to person. Further, the includeNoDM and retired restrictions should be part of the outer join, because it would otherwise collapse into an inner join inside the database. (this is standard database behaviour - if part of the WHERE clause refers to the left-hand side of a LEFT OUTER join, the join effectively becomes an INNER join, because any restriction except IS NULL is FALSE for a NULL field - and NULL's are what you get for missing left-hand side rows).
All that can be fixed via this override of SetJoin, which sets up the outer join, puts in the special restrictions, and removes them from the RestrictionHelper, thereby avoiding having them inserted later on in the query...SetRestriction(params ArchiveRestrictionInfo[])
Override to allow special dynamic selection behaviour of restrictions; in particular, handle the noMailings and Retired restrictions, which are modifiers rather than mapping directly to simple database file/operator/value.
Declaration
public override bool SetRestriction(params ArchiveRestrictionInfo[] restrictions)Parameters
| Type | Name | Description |
|---|---|---|
| ArchiveRestrictionInfo[] | restrictions |
Returns
| Type | Description |
|---|---|
| bool | true if this is a person-level selection |
Overrides
Remarks
If there are any person-level restrictions, ensure that a restriction on retired (person) is present. If not, add one, set to exclude retired persons.
If the includePersonRestriction has been set to true, make this a person level query, but keep the primary key to be contact to compress away duplicate contacts generated by multiple persons. Parallel handling of contact-level modifiers can be found in SelectionDynamicContactExtender.
