Takes three parameters, ChildTableName, ParentTableName, Mode

Usage:

ChildTableName, ParentTableName, Mode
ChildTableName, ParentTableName, ["All"]

Description:

The Attached Parent Records will be added to the Query, using the specified mode.

Mode must be one of: "All", "One", "Discard"

• "All": Every Parent Record for Every pre-existing Record will be loaded. If more than one Parent Records exists the pre-existing Record will be duplicated. If no Parent records are found for a pre-existing Record, the Records will remain with blank fields values for the Parent table.
  This is the default mode when this optional parameter is omitted.
• "One": Only One Parent Record for Every pre-existing Record will be loaded. If more than one Parent Record exists the pre-existing Record a single Parent will be chosen at random. If no Parent records are found for a pre-existing Record, the Records will remain with empty fields values for the Parent table.
  
  
• "Discard": Every Parent Record for Every pre-existing Record will be loaded. If more than one Parent Records exists the pre-existing Record will be duplicated. If no Parent records are found for a pre-existing Record, the Records will be removed from the Query. Note that this is the typical behavior for SQL.

Example:

Parents "MemTab.Group", "MemTab.Person"

Parents "MemTab.Group", "MemTab.Person", "One"
