We have an entity, TagEntity, which inherits from FullAuditedEntity and implements IMustHaveTenant.
To get all tags belonging to the current tenant we perform the following query (where _tagRepository is an instance of IRepository):
var tags = _tagRepository.GetAll().ToList();
This results in the database performing a clustered index scan on the Tags table, despite there being an index on TenantId and IsDeleted.
Whereas, the following SQL query gets a non clustered index seek as expected:
SELECT * FROM Tags WHERE TenantId = 3 AND IsDeleted = 0
It appears that this issue is related to the use of dynamic data filters and IMustHaveTenant generating clauses such as:
(([Var_8].[TenantId] = @DynamicFilterParam_000005) OR ( CAST( [Var_8].[TenantId] AS int) IS NULL) )
Is there any way that we can write queries using IRepository repositories so that the generated SQL doesn’t result in an index scan?
