In X++, what is the primary purpose of a method?

To define the structure of a database table

To handle user interface events only

To encapsulate a set of statements that can be executed together

A developer is writing a data migration routine that must insert or update records in a custom table. The routine will be run by an administrator and must handle large volumes (over 100,000 records). The developer needs to ensure the routine completes within a reasonable time and does not lock the table for extended periods. Which approach is best?

Use a loop with ttsbegin/ttscommit around each individual record operation.

Use a batch task with a series of smaller transactions, each processing a subset of records.

Use insert_recordset for new records and update_recordset for updates, but handle the logic to determine which records are new or existing.

Use a while select with forUpdate and call update() or insert() for each record, wrapped in a single transaction.

Which of the following is a common best practice warning in X++ development?

Using the 'break' statement in a loop

Declaring a variable with a meaningful name

Using the 'select' statement without a 'where' clause on a large table

Using comments to explain complex logic
