Example 96 with TableGroup

use of org.hibernate.sql.ast.tree.from.TableGroup in project hibernate-orm by hibernate.

the class CaseStatementDiscriminatorMappingImpl method generateFetch.

@Override
public BasicFetch generateFetch(FetchParent fetchParent, NavigablePath fetchablePath, FetchTiming fetchTiming, boolean selected, String resultVariable, DomainResultCreationState creationState) {

    // Since the expression is lazy, based on the available table reference joins,
    // we need to force the initialization in case this is a fetch
