public interface BaseHavingBuilder<T extends BaseHavingBuilder<T>>

A base interface for builders that support having. This is related to the fact, that a query builder supports group by and having clauses.

Method Detail

havingSubquery

SubqueryInitiator<RestrictionBuilder<T>> havingSubquery()

Starts a SubqueryInitiator for the left hand side of a predicate. When the subquery builder and the restriction builder for the right hand side are finished, the predicate is added to the parent predicate container represented by the type T.

Returns:

The subquery initiator for building a subquery

havingSubquery

SubqueryInitiator<RestrictionBuilder<T>> havingSubquery(String subqueryAlias,
                                                      String expression)

Starts a SubqueryInitiator for the left hand side of a predicate. All occurrences of subqueryAlias in expression will be replaced by the subquery. When the subquery builder and the restriction builder for the right hand side are finished, the predicate is added to the parent predicate container represented by the type T.

Parameters:

subqueryAlias - The alias for the subquery which will be replaced by the actual subquery

expression - The expression which will be used as left hand side of a predicate

Returns:

The subquery initiator for building a subquery

having

RestrictionBuilder<T> having(String expression)

Starts a RestrictionBuilder for a having predicate with the given expression as left hand expression. When the builder finishes, the predicate is added to the parent predicate container represented by the type T.

Parameters:

expression - The left hand expression for a having predicate

Returns:

The restriction builder for the given expression

havingCase

CaseWhenStarterBuilder<RestrictionBuilder<T>> havingCase()

Starts a CaseWhenBuilder for a where predicate. When the CaseWhenBuilder and the restriction builder for the right hand side are finished, the predicate is added to the parent predicate container represented by the type T.

Returns:

A CaseWhenBuilder

havingSimpleCase

SimpleCaseWhenStarterBuilder<RestrictionBuilder<T>> havingSimpleCase(String expression)

Starts a SimpleCaseWhenBuilder for a where predicate. When the CaseWhenBuilder and the restriction builder for the right hand side are finished, the predicate is added to the parent predicate container represented by the type T.

Parameters:

expression - Case operand expression

Returns:

A CaseWhenBuilder

havingExists

SubqueryInitiator<T> havingExists()

Starts an exists predicate for the having clause with a subquery on the right hand side. When the builder finishes, the predicate is added to the parent predicate container represented by the type T.

Returns:

The subquery initiator for building a subquery

havingNotExists

SubqueryInitiator<T> havingNotExists()

Starts an exists predicate for the having clause with a subquery on the right hand side. When the builder finishes, the predicate is added to the parent predicate container represented by the type T.

Returns:

The subquery initiator for building a subquery
