Method Detail

or

RestrictionBuilder<CaseWhenOrThenBuilder<T>> or(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

orSubquery

SubqueryInitiator<RestrictionBuilder<CaseWhenOrThenBuilder<T>>> orSubquery()

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 disjunct.

Returns:

The subquery initiator for building a subquery

orSubquery

SubqueryInitiator<RestrictionBuilder<CaseWhenOrThenBuilder<T>>> orSubquery(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 disjunct.

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

orExists

SubqueryInitiator<CaseWhenOrThenBuilder<T>> orExists()

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 disjunct.

Returns:

The subquery initiator for building a subquery

orNotExists

SubqueryInitiator<CaseWhenOrThenBuilder<T>> orNotExists()

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 disjunct.

Returns:

The subquery initiator for building a subquery

and

CaseWhenAndBuilder<CaseWhenOrThenBuilder<T>> and()

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

Returns:

The case when and builder
