Question

我正在使用Micro ORM PetaPOCO，我想使用类似的查询，我得到例外，如果有人知道，请帮助我。

var context = new PetaPoco.Database(Connection.connectionstring);
            SqlQuery = @"SELECT CmsPage.PageId, CmsPage.PageTitle, CmsPage.MenuId, CmsPage.PageDescription, CmsPage.Title, CmsPage.MetaKeyword, CmsPage.MetaDescription, CmsPage.CreatedDate, CmsPage.IsActive
            FROM ( SELECT ROW_NUMBER() OVER (ORDER BY CmsPage.PageTitle) AS row, CmsPage.PageId, CmsPage.PageTitle, CmsPage.MenuId, CmsPage.PageDescription,
            CmsPage.Title, CmsPage.MetaKeyword, CmsPage.MetaDescription, CmsPage.CreatedDate, CmsPage.IsActive FROM CmsPage ) AS CmsPage WHERE
            CmsPage.PageTitle LIKE @0 and row > ((@CurrPage - 1) * @PageSize)  and  row <= (@CurrPage * @PageSize)";


            List<CmsPagePOCO> obCmsPagePOco = context.Query<CmsPagePOCO>(
                SqlQuery, 
                    new 
                    {
                        @CurrPage = CurrPage,
                        @PageSize = PageSize,
                        @PageTitle = "%" + PageTitle + "%"

                    }).ToList();

            return obCmsPagePOco;

获得此例外：

对象类型＆lt;＆gt; f__AnonymousType1`3 [[System.Int32，mscorlib，Version = 4.0.0.0，Culture = neutral，PublicKeyToken = b77a5c561934e089]，[System.Int32，mscorlib，Version = 4.0]不存在映射。 0.0，Culture = neutral，PublicKeyToken = b77a5c561934e089]，[System.String，mscorlib，Version = 4.0.0.0，Culture = neutral，PublicKeyToken = b77a5c561934e089]]到已知的托管提供者本机类型。

您正在@0中将like与命名参数混合

更改为：

CmsPage.PageTitle LIKE @PageTitle and row > ...
