Method Details

or

PredicateOrBuilder<PredicateBuilder> or()

Starts a PredicateOrBuilder which is a predicate consisting only of disjunctiv connected predicates. When the builder finishes, the predicate is added to the parent predicate container represented by the type T.

Returns:

The or predicate builder for the where clause

setExpression

PredicateBuilder setExpression(String expression)

Sets the given expression as expression for the where clause.

Parameters:

expression - The where expression

Returns:

The builder

setExpressionSubqueries

MultipleSubqueryInitiator<PredicateBuilder> setExpressionSubqueries(String expression)

Starts a MultipleSubqueryInitiator for expression of the where clause.

All occurrences of subsequently defined subqueryAliases in expression will be replaced by the respective subquery. When the builder finishes, the resulting expression is used as expression for the where clause.

Parameters:

expression - The where expression

Returns:

The subquery initiator for building multiple subqueries for their respective subqueryAliases
