我正在编写一个将数据插入数据库的查询，但当我在输出处打印查询时，它会变成“显示tbl\\U名称中的列”查询。我正在写下面的问题。但它的执行方式如图所示

$table_name1 = $wpdb->prefix . \'fullcontact\';
    $sql1=$wpdb->insert( $table_name1, array(
        \'status\' => $status,
        \'request_id\' => $req_id,
        \'likelihood\' => $likelihood,
        \'photos\' => $photos,
        \'chats\' => $chats,
        \'websites\' => $websites,
        \'fullname\' => $fullname,
        \'familyname\' => $familyname,
        \'givenname\' => $givenname,
        \'organisation\' => $organisation,
        \'normalizedlocation\' => $normalizedlocation,
        \'city\' => $city,
        \'state\' => $state,
        \'country\' => $country,
        \'age\' => $age,
        \'agerange\' => $agerange,
        \'gender\' => $gender,
        \'locationgeneral\' => $locationgeneral,
        \'socialprofiles\' => $socialprofiles,
        \'scores\' => $scores,
        \'topics\' => $topics
    ) );

    //exit( var_dump( $wpdb->last_query ) );
    $wpdb->show_errors();
    $wpdb->print_error($sql1);
