However, the table still needs to have a minimum of 500 rows as the minimum row threshold did not change.

As before the update of the statistics will apply the default sample rate which is dynamic and based on the # of rows.

Processes to supplement additional update statistics in SAP BW were implemented and documented with SAP OSS Note #849062 – ‘Optimizer statistics for Info Cubes in BW’.

When SQL Server introduced automatic update statistics with SQL Server 7.0 in 1998, the basic design was to keep track of the number of changes to a table.

This means for today’s SQL Server releases, if a column of a table would have been exposed to modifications which exceeded 20% of the # of rows in the table, an automatic update statistics would be triggered.

The update is executed against the index B-Trees including that column as leading column in the index or to the column statistics of such a column.

When the number of changes on a table exceeded a certain percentage threshold an automatic update of the statistics would be executed.

Over the next releases up to SQL Server 2005, several changes were made to the principal data collected in the statistics and the asynchronous update of statistics was introduced.
