Examples with JdbcSelectExecutor org.hibernate.sql.exec.spi.JdbcSelectExecutor used on opensource projects

Example 1 with JdbcSelectExecutor

use of org.hibernate.sql.exec.spi.JdbcSelectExecutor in project hibernate-orm by hibernate.

the class NativeSelectQueryPlanImpl method performScroll.

@Override
public ScrollableResultsImplementor<R> performScroll(ScrollMode scrollMode, DomainQueryExecutionContext executionContext) {
    if (executionContext.getQueryOptions().getEffectiveLimit().getMaxRowsJpa() == 0) {
        return EmptyScrollableResults.INSTANCE;
    }
    final List<JdbcParameterBinder> jdbcParameterBinders;
    final JdbcParameterBindings jdbcParameterBindings;
    final QueryParameterBindings queryParameterBindings = executionContext.getQueryParameterBindings();
    if (parameterList == null || parameterList.isEmpty()) {
        jdbcParameterBinders = Collections.emptyList();
        jdbcParameterBindings = JdbcParameterBindings.NO_BINDINGS;
    } else {
        jdbcParameterBinders = new ArrayList<>(parameterList.size());
        jdbcParameterBindings = new JdbcParameterBindingsImpl(parameterList.size());
        jdbcParameterBindings.registerNativeQueryParameters(queryParameterBindings, parameterList, jdbcParameterBinders, executionContext.getSession().getFactory());
    }
    final JdbcSelect jdbcSelect = new JdbcSelect(sql, jdbcParameterBinders, resultSetMapping, affectedTableNames, Collections.emptySet());
    final JdbcSelectExecutor executor = JdbcSelectExecutorStandardImpl.INSTANCE;
    // return jdbcServices.getJdbcSelectExecutor().scroll(
    return executor.scroll(jdbcSelect, scrollMode, jdbcParameterBindings, SqmJdbcExecutionContextAdapter.usingLockingAndPaging(executionContext), null);
