Collecting statistics normally involves a full-table scan, so you may need to collect statistics for large tables during off-hours.

For very large tables, you can also collect statistics on a sampled subset of table rows instead of all the rows for a table, using the SAMPLE clause. For more information, see Sampling Statistics with the USING SAMPLE Option.
