In a SQL database query, a correlated subquery (also known as a synchronized subquery) is a subquery (a query nested inside another query) that uses values from the outer query. This can have major impact on performance because the correlated subquery might get recomputed every time for each row of the outer query is processed.
The Count operator counts the number of elements in the given collection. An overload taking a predicate, counts the number of elements matching the predicate. The standard query operator API also specifies certain operators that convert a collection into another type: [3] AsEnumerable: Statically types the collection as an IEnumerable<T>. [4]

If you need to make changes to a number of articles based on a particular query, you can post to the bot requests page, depending on how many changes are needed. For long-term review and checking, database reports are available. Quarry does not have access to page content, so queries which require checking wikitext cannot be answered with Quarry.
