And indeed, since we couldn’t parameterize the array, we simply embedded its values – as constants – into the SQL query. Up to now, all versions of EF have provided the following translation: SELECT. But what can we do for other databases, where this does not exist? Leveraging this, we pass the array of blog names as a SQL parameter directly to ANY – that’s – and get the perfect translation. WHERE b."Name" = ANY is very similar to the inline collection translation above with IN, but uses the PostgreSQL-specific ANY construct, which can accept an array type. Where(b => new (DbType = Object)], CommandType='Text', CommandTimeout='30'] You could use the following LINQ query to do so: var blogs = await context.Blogs Starting from something simple, imagine you have a bunch of Blogs, and want to query out two Blogs whose names you know. Let’s examine such a case, which also happens to be related to a highly-voted EF performance issue. In EF’s quest to translate more and more LINQ queries to SQL, we sometimes encounter odd and problematic corner cases. Let’s dive in!
