Suppose we have two entities: `User` and `Topic`, and two repositories are defined in the domain class:
```csharp
var userRepository = fsql.GetGuidRepository<User>();
var topicRepository = fsql.GetGuidRepository<Topic>();
var userRepository = fsql.GetRepository<User>();
var topicRepository = fsql.GetRepository<Topic>();
```
In practice, we always worry about the data security of `topicRepository`, that is, it is possible to query or change the topic of other users. Therefore, we have made improvements in the v0.0.7 version, adding the filter lambda expression parameter.
```csharp
var userRepository = fsql.GetGuidRepository<User>(a => a.Id == 1);
var topicRepository = fsql.GetGuidRepository<Topic>(a => a.UserId == 1);
var userRepository = fsql.GetRepository<User>(a => a.Id == 1);
var topicRepository = fsql.GetRepository<Topic>(a => a.UserId == 1);
```
* Attach this condition when querying/modifying/deleting, so that the data of other users will not be modified.
