where

public jakarta.persistence.criteria.CriteriaUpdate<T> where(jakarta.persistence.criteria.Expression<Boolean> restriction)

Specified by:

where in interface jakarta.persistence.criteria.CriteriaUpdate<T>

Overrides:

where in class CommonAbstractCriteriaImpl<T>

Parameters:

restriction - a simple or compound boolean expression

Returns:

the modified query

Parameters:

restrictions - zero or more restriction predicates

Returns:

the modified query
