Question

我的MySQL表格如下：

 'id'       'name'    'type'
 1           name1       A         
 2           name2       B 
 3           name3       A  
 4           name4       C 
 5           name5       C

如何在NOTORM PHP中获得所有不同的类型，即A，B，C。

Answer 1

API文档不会以直观的方式覆盖它，但您只需使用按功能分组来获取不同的值：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using ESBAMPortal.DataLayer;
using ESBAMPortal.Models;
using PagedList;
using ESBAMPortal.DomainClasses.BAM;
using System.IO;

namespace ESBAMPortal.Controllers
{
    public class SupplierStockUpdateController : Controller
    {
        private IRepository<SupplierStockUpdate> SupplierStockUpdateRepository;

        public SupplierStockUpdateController(BAMContext context)
        {
            this.SupplierStockUpdateRepository = new EFRepository<SupplierStockUpdate>(context);
        }

        private string TranslateStatusFilter(int status)
        {
            string ret = "";

            switch (status)
            {
                case 2:
                    ret = "Pending";
                    break;
                case 3:
                    ret = "Complete";
                    break;
            }

            return ret;

        }

        // GET: /SupplierStock/
        public ActionResult Index(string sortOrder, int? page, int? itemsPerPage, SupplierStockUpdateViewModel vm)
        {

            string statusFilter = TranslateStatusFilter(vm.SelectedStatusId);

            ViewBag.CurrentItemsPerPage = itemsPerPage;
            ViewBag.TimeReceivedSort = String.IsNullOrEmpty(sortOrder) ? "timeReceived" : "";
            ViewBag.SupplierSort = sortOrder == "supplier" ? "supplier_desc" : "supplier";

            var query = this.SupplierStockUpdateRepository.GetAll();
            switch (sortOrder)
            {
                case "timeReceived":
                    query = query.OrderBy(f => f.TimeReceived);
                    break;
                case "supplier":
                    query = query.OrderBy(f => f.SupplierCode);
                    break;
                case "supplier_desc":
                    query = query.OrderByDescending(f => f.SupplierCode);
                    break;
                default:
                    query = query.OrderByDescending(f => f.TimeReceived);
                    break;
            }

            if (statusFilter == "Pending" || statusFilter == "Complete")
            {
                query = query.Where(x => x.ImportStatus == statusFilter);
            }

            //shove results into view model
            List<SupplierStockUpdateViewModel> SupplierStockUpdatesVM = new List<SupplierStockUpdateViewModel>();

            DateTime start = new DateTime();
            DateTime end = new DateTime();

            foreach (var item in query.ToList())
            {
                SupplierStockUpdateViewModel SupplierStockUpdateVM = new SupplierStockUpdateViewModel();

                SupplierStockUpdateVM.ActivityID = item.ActivityID;
                SupplierStockUpdateVM.InterchangeId = item.InterchangeId;
                SupplierStockUpdateVM.TimeReceived = item.TimeReceived;
                SupplierStockUpdateVM.TimeProductLookupRequested = item.TimeProductLookupRequested;
                SupplierStockUpdateVM.TimeProductLookupResponse = item.TimeProductLookupResponse;
                SupplierStockUpdateVM.TimeInsertRequested = item.TimeInsertRequested;
                SupplierStockUpdateVM.TimeInsertResponse = item.TimeInsertResponse;
                SupplierStockUpdateVM.SupplierCode = item.SupplierCode;
                SupplierStockUpdateVM.RowsInserted = item.RowsInserted;
                SupplierStockUpdateVM.TimeOfException = item.TimeOfException;
                SupplierStockUpdateVM.ReceivedFilename = item.ReceivedFilename;
                SupplierStockUpdateVM.ImportStatus = item.ImportStatus;
                SupplierStockUpdateVM.ImportErrors = item.ImportErrors;

                start = (item.TimeReceived == null) ? DateTime.MinValue : (System.DateTime)item.TimeReceived;

                if (item.TimeOfException == null)
                {
                    SupplierStockUpdateVM.TimeOfExceptionString = "NA";
                    if (item.TimeInsertResponse != null)
                    {
                        end = (System.DateTime)item.TimeInsertResponse;
                    }
                    else
                    {
                        //no exception but process still running so give a duration of 0
                        end = start;
                    }
                }
                else
                {
                    SupplierStockUpdateVM.TimeOfExceptionString = item.TimeOfException.ToString();
                    end = (System.DateTime)item.TimeOfException;
                }

                if (start == DateTime.MinValue)
                {
                    SupplierStockUpdateVM.TotalDuration = 0;
                }
                else
                {
                    SupplierStockUpdateVM.TotalDuration = (end - start).TotalSeconds;
                }

                SupplierStockUpdatesVM.Add(SupplierStockUpdateVM);
            }

            int pageSize = (itemsPerPage ?? 10);
            int pageNumber = (page ?? 1);

            return View(SupplierStockUpdatesVM.ToPagedList(pageNumber, pageSize));
        }
    }
}

设置GROUP BY和HAVING

运行不同的内容时（不是在数据库级别，但在输出级别相同）。

Answer 2

使用sql查询

SELECT DISTINCT type FROM yourtable

使用notORM API：

('SELECT DISTINCT type FROM ') $table

另一种可能性是使用工作arround：

$table->select('DISTINCT type')

在NOTORM中选择不同的列值
