Calculate Space Requirements When Rows Span Pages
Follow these steps to determine the amount of space needed to store the data in a table with rows that span pages:
1. Determine the number of pages per row, as follows:
pages_per_row = row_size / max row size
Round up to the nearest integer.
2. Determine the number of data pages needed for the table, as follows:
data_pages = num_rows * pages_per_row
