Question

我有一个查询

     public void saveReportId(BigDecimal reportId) {
               entityManager.createQuery("UPDATE ReportEntity r set r.report_id = reportId WHERE s.phase = :phase")
                       .setParameter("reportId", reportId)
                       .setParameter("phase", ReportStatus.NEW.getValue())
                       .executeUpdate();
      }

但是，没有使用我在参数中传递的reportId值填充表，而是出现了错误：

Problem compiling - The state field cannot be resolved.

Answer 1

缺少:reportId，也将s.phase替换为r.phase。只需更新即可：

entityManager.createQuery("update ReportEntity r set r.report_id = :reportId where r.phase = :phase")
                           .setParameter("reportId", reportId)
                           .setParameter("phase", ReportStatus.NEW.getValue())
                           .executeUpdate();

希望这会有所帮助：）

在您的命名参数查询中，您可能会想念您遵循规则reportId。因此，就您而言，只需注意entityManager.createQuery("UPDATE ReportEntity r set r.report_id = :reportId WHERE s.phase = :phase")参数。只需这样更改第二个：

function create_collaborations()
{
    register_post_type('collaborations',
        array('labels' => array('name' => __('collaborations'),'singular_name' => __('Collaborations')),'public' => true,'has_archive' => false,'rewrite' => array('slug' => 'collaborations'))
    );
}
add_action('init','create_collaborations');

function cw_post_type_collaborations()
{
    $supports = array('title', 'editor', 'thumbnail', 'revisions');

    $labels = array(
        'name'          => _x('Collaborations', 'plural'),
        'singular_name' => _x('Collaborations', 'singular'),
        'menu_name'     => _x('Collaborations', 'admin menu'),
        'name_admin_bar'=> _x('Collaborations', 'admin bar'),
        'add_new'       => _x('Add New', 'add new'),
        'add_new_item'  => __('Add New Collaborations'),
        'new_item'      => __('New Collaborations'),
        'edit_item'     => __('Edit Collaborations'),
        'view_item'     => __('View Collaborations'),
        'all_items'     => __('View Collaborations'),
        'search_items'  => __('Search Collaborations'),
        'not_found'     => __('No Collaborations found.')
    );

    $args = array(
        'supports'      => $supports,
        'labels'        => $labels,
        'public'        => true,
        'query_var'     => true,
        'rewrite'       => array('slug' => 'collaborations'),
        'has_archive'   => true,
        'hierarchical'  => false
    );

    register_post_type('collaborations', $args);
}
add_action('init', 'cw_post_type_collaborations');
