You can also use navigations in defining global query filters. Using navigations in query filter will cause query filters to be applied recursively. When EF Core expands navigations used in query filters, it will also apply query filters defined on referenced entities....
EF Core – QueryFilter & Interception 主要参考 Global Query Filters Interceptors QueryFilter QueryFilter 就是默认过滤, 非常适合用来做 Soft Delete builder.HasQueryFilter(e => EF.Property<DateTimeOffset?>(e,"DateDeleted") ==null); 设置这个以后, 一般的 query 语句就拿不到 deleted 的 row 了 如果...
因此,最终使用了全局查询过滤器(GlobalQuery Filters) 下面的代码段检查是否存在具有TenantId和IsDelated字段的模型,并根据这些字段筛选对象。 EFCore 官方说明不支持多个过滤器,因此我们必须使用比较复杂的表达式和表达式合并方法来解决此问题 下面是具体的代码示例: publicpartialclassMasterContext : DbContext {publicGuid...
In a normal query you would apply custom filters with.Where()on the DbSet but I also need to ensure any.Include()collections are also filtered according to the ruleset (OData style expands). AFAIK Global Query Filters have the benefit of being applied on the entities regardless of whether i...
Global query filters produce too many parameters Optimize update path for single property JSON element JSON columns can be used in compiled models Unneeded parentheses removed in SQL queries Set operations are supported over non-entity projections with different facets ...
