Union(Query, bool)
Creates a new UNION operation.
public Union(Query query, bool unionAll)
Parameters
queryQueryThe query to union with the base query.
unionAllboolIf true, uses UNION ALL (keeps duplicates). If false, uses UNION (removes duplicates).
Remarks
UNION ALL is generally faster because it doesn't need to check for and remove duplicates. Use UNION ALL when you know there are no duplicates or when duplicates are acceptable.
