Method Summary

Modifier and Type	Method and Description
Select<R>	except(Select<? extends R> select) Apply the EXCEPT (or MINUS) set operation.
Select<R>	exceptAll(Select<? extends R> select) Apply the EXCEPT ALL set operation.
int	fetchCount() Deprecated. - 3.5.0 - [#3356] - This method is being removed as it is confusingly different from all the other types of ResultQuery.fetch() methods, in that it modifies the original Select statement by wrapping it. In particular, this method can be easily confused with ResultQuery.fetch(Field), or more concretely fetch(count()), which has an entirely different semantics. Use DSLContext.fetchCount(Select) instead.
List<Field<?>>	getSelect() All fields selected in this query
Select<R>	intersect(Select<? extends R> select) Apply the INTERSECT set operation.
Select<R>	intersectAll(Select<? extends R> select) Apply the INTERSECT ALL set operation.
Select<R>	union(Select<? extends R> select) Apply the UNION set operation.
Select<R>	unionAll(Select<? extends R> select) Apply the UNION ALL set operation.

fetchCount

@Deprecated
int fetchCount()
                     throws DataAccessException

Deprecated. - 3.5.0 - [#3356] - This method is being removed as it is confusingly different from all the other types of ResultQuery.fetch() methods, in that it modifies the original Select statement by wrapping it. In particular, this method can be easily confused with ResultQuery.fetch(Field), or more concretely fetch(count()), which has an entirely different semantics. Use DSLContext.fetchCount(Select) instead.

Execute this query in the context of its attached executor and return a COUNT(*) value.

This wraps a pre-existing SELECT query in another one to calculate the COUNT(*) value, without modifying the original SELECT. An example:

 -- Original query:
 SELECT id, title FROM book WHERE title LIKE '%a%'

 -- Wrapped query:
 SELECT count(*) FROM (
   SELECT id, title FROM book WHERE title LIKE '%a%'
 )
 

This is particularly useful for those databases that do not support the COUNT(*) OVER() window function to calculate total results in paged queries.

Returns:

The COUNT(*) result

Throws:

DataAccessException - if something went wrong executing the query
