Using a "while select" statement with a table buffer variable is the most efficient and straightforward way to iterate over multiple records in X++. This approach allows you to retrieve and manipulate multiple records from a specific table in an organized manner.

The "while select" statement automatically manages the iteration over the records. When this statement is executed, it opens a cursor, which fetches the records from the database and loads them into the specified table buffer variable. The iteration continues until there are no more records to process. This makes the code not only easier to read but also more efficient, as it utilizes the database's ability to process data directly.

Additionally, by using a table buffer variable, developers can reference the current record's fields directly in the loop, simplifying access to data and enhancing code clarity. This method takes advantage of X++'s integrated database capabilities, ensuring that operations on the records are optimized.

In comparison, alternatives like using a shared variable with the next() method or employing a RecordSortedList variable can introduce unnecessary complexity or may not be as efficient for simple data access patterns. These methods can be useful in specific scenarios, but they do not provide the same simplicity and performance benefits as the "while select" statement with a table buffer.
