public mysql_xdevapi\Collection::find(string $search_condition = ?): mysql_xdevapi\CollectionFind

Search a database collection for a document or set of documents. The found documents are returned as a CollectionFind object is to further modify or fetch results from.

Bağımsız Değişkenler


Although optional, normally a condition is defined to limit the results to a subset of documents.

Multiple elements might build the condition and the syntax supports parameter binding. The expression used as search condition must be a valid SQL expression. If no search condition is provided (field empty) then find('true') is assumed.
