HasRows

HasRows is a property found in certain data access technologies, most notably in ADO.NET within the .NET framework. It is a boolean property of a DbDataReader object, which is used to read a forward-only stream of rows from a data source. The HasRows property returns true if the data reader contains one or more rows, and false otherwise. This is particularly useful for determining if a query returned any results before attempting to process them. For instance, a developer might check HasRows after executing a query to decide whether to iterate through the results or display a "no records found" message. It allows for efficient handling of queries that may legitimately return no data, preventing potential errors or unexpected behavior when attempting to access data that does not exist. The property is typically checked immediately after opening the data reader or after calling the Read() method for the first time.
