Method Detail

and

RestrictionBuilder<CaseWhenAndBuilder<T>> and(String expression)

Starts a RestrictionBuilder for a case when predicate with the given expression as left hand expression. When the builder finishes, the predicate is added this predicate container.

Parameters:

expression - The left hand expression for a case when predicate

Returns:

The restriction builder for the given expression

andSubquery

SubqueryInitiator<RestrictionBuilder<CaseWhenAndBuilder<T>>> andSubquery()

Starts a SubqueryInitiator for the left hand side of a when predicate. When the subquery builder and the restriction builder for the right hand side are finished, the when predicate in conjunction with it's then expression are added to this predicate container as conjunct.

Returns:

The subquery initiator for building a subquery

andSubquery

SubqueryInitiator<RestrictionBuilder<CaseWhenAndBuilder<T>>> andSubquery(String subqueryAlias,
                                                                         String expression)

Starts a SubqueryInitiator for the left hand side of a when 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 when predicate in conjunction with it's then expression are added to this predicate container as conjunct.

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. This expression contains the subqueryAlias to define the insertion points for the subquery.

Returns:

The subquery initiator for building a subquery

andSubqueries

MultipleSubqueryInitiator<RestrictionBuilder<CaseWhenAndBuilder<T>>> andSubqueries(String expression)

Starts a MultipleSubqueryInitiator for the left hand side of a when predicate.

All occurrences of subsequently defined subqueryAliases in expression will be replaced by the respective subquery. When the builder finishes, the resulting expression is used for the left hand side of a when predicate.

Parameters:

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

Returns:

The subquery initiator for building multiple subqueries for their respective subqueryAliases

Since:

1.2.0

andSubquery

SubqueryBuilder<RestrictionBuilder<CaseWhenAndBuilder<T>>> andSubquery(FullQueryBuilder<?,?> criteriaBuilder)

Starts a SubqueryBuilder based on the given criteria builder for the left hand side of a when predicate. When the subquery builder and the restriction builder for the right hand side are finished, the when predicate in conjunction with it's then expression are added to this predicate container as conjunct.

Parameters:

criteriaBuilder - The criteria builder to base the subquery on

Returns:

The subquery builder for building a subquery

Since:

1.2.0

andSubquery

SubqueryBuilder<RestrictionBuilder<CaseWhenAndBuilder<T>>> andSubquery(String subqueryAlias,
                                                                       String expression,
                                                                       FullQueryBuilder<?,?> criteriaBuilder)

Starts a SubqueryBuilder based on the given criteria builder for the left hand side of a when 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 when predicate in conjunction with it's then expression are added to this predicate container as conjunct.

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. This expression contains the subqueryAlias to define the insertion points for the subquery.

criteriaBuilder - The criteria builder to base the subquery on

Returns:

The subquery builder for building a subquery

Since:

1.2.0

andExists

SubqueryInitiator<CaseWhenAndBuilder<T>> andExists()

Returns:

The subquery initiator for building a subquery

andNotExists

SubqueryInitiator<CaseWhenAndBuilder<T>> andNotExists()

Starts an exists predicate for the when clause with a subquery on the right hand side. When the builder finishes, the when predicate in conjunction with it's then expression are added to this predicate container as conjunct.

Returns:

The subquery initiator for building a subquery

andExists

SubqueryBuilder<CaseWhenAndBuilder<T>> andExists(FullQueryBuilder<?,?> criteriaBuilder)

Starts an exists predicate for the when clause with a subquery on the right hand side based on the given criteria builder. When the builder finishes, the when predicate in conjunction with it's then expression are added to this predicate container as conjunct.

Parameters:

criteriaBuilder - The criteria builder to base the subquery on

Returns:

The subquery builder for building a subquery

Since:

1.2.0

andNotExists

SubqueryBuilder<CaseWhenAndBuilder<T>> andNotExists(FullQueryBuilder<?,?> criteriaBuilder)

Starts an exists predicate for the when clause with a subquery on the right hand side based on the given criteria builder. When the builder finishes, the when predicate in conjunction with it's then expression are added to this predicate container as conjunct.

Parameters:

criteriaBuilder - The criteria builder to base the subquery on

Returns:

The subquery builder for building a subquery

Since:

1.2.0

or

CaseWhenOrBuilder<CaseWhenAndBuilder<T>> or()

Starts a case when or builder which connects it's predicates with the OR operator. When the builder finishes, the predicate is added to this predicate container as conjunct.

Returns:

The case when or builder
