我有一个名为'business'的表,其中包含以下示例数据:

Street - 150 N Michigan Ave.
City - Chicago
State - IL
Zip - 60601

当我运行查询时

SELECT business.* 
    WHERE MATCH(business.Street, business.City, business.State, business.Zip)
                AGAINST('*150*' IN BOOLEAN MODE)
-- IT WORKS


SELECT business.* 
    WHERE MATCH(business.Street, business.City, business.State, business.Zip)
                AGAINST('*Chicago*' IN BOOLEAN MODE)
-- IT WORKS


SELECT business.* 
    WHERE MATCH(business.Street, business.City, business.State, business.Zip)
                AGAINST('*60601*' IN BOOLEAN MODE)
-- IT WORKS


SELECT business.* 
    WHERE MATCH(business.Street, business.City, business.State, business.Zip)
                AGAINST('*IL*' IN BOOLEAN MODE)
-- DOESNT WORK!!

那么最后一个查询有什么问题？

有任何想法吗？

对于我的问题,让我们考虑以下示例表数据:

产品ID产品名称价格分类

1 Apple 5.00 Fruits
2 Apple 5.00 Food
3 Orange 3.00 Fruits
4 Banana 2.00 Fruits

我需要一个查询,它将产生以下数据集:

产品ID产品名称价格分类

1 Apple 5.00 Fruits
3 Orange 3.00 Fruits
4 Banana 2.00 Fruits

如您所见,ProductID 2已被忽略/忽略,因为Apple已存在于结果中,即每个产品必须只出现一次,无论类别或价格如何.

谢谢

在我的Web API控制器方法中,在映射UpdatePlaceDTO到之前PlaceMaster,我进行数据库调用以填充Map未涵盖的属性,但由于某种原因,AutoMapper使这些属性为null.

var mappedPlaceMaster = _mapper.Map<PlaceMaster>(placeMasterDTO);
// mappedPlaceMaster.EntityId is null 

我已经尝试过IgnoreExistingMembers的许多解决方案,但它们都不起作用.

这就是我所拥有的

    public class PlaceMapperProfile : Profile
    {

        protected override void Configure()
        {
            // TO DO: This Mapping doesnt work. Need to ignore other properties
            //CreateMap<UpdatePlaceDto, PlaceMaster>()
            //    .ForMember(d => d.Name, o => o.MapFrom(s => s.Name))
            //    .ForMember(d => d.Description, o => o.MapFrom(s => s.Description))
            //    .ForMember(d => d.ParentPlaceId, o => o.MapFrom(s => s.ParentPlaceId))
            //    .ForMember(d => d.LeftBower, o => o.MapFrom(s => s.LeftBower))
            //    .ForMember(d => …
