Data-Row Format and Storage

The variable length of a data row has the following consequences for row storage:
  • A page might contain one or more whole rows.
  • A page might contain portions of one or more rows.
  • A page might contain a combination of whole rows and partial rows.
  • An updated row might increase in size and become too long to return to its original storage location in a row.

The following paragraphs describe the guidelines that the database server follows during data storage.
