Errata (updated 3rd Aug 2011)
Page 90, start of second paragraph: “If you had analyzed the column to the maximum of 75 buckets,” the value 75 is the default number of buckets. The maximum is 254
Page 102, table 6-6: I define lf_rows as “number of current rows in the index (excluding deleted rows)”, similarly I defined lf_rows_len as “Total space requirement in bytes of leaf rows (excluding deleted rows)”. In both cases that should be including not excluding. i.e. the figures include the values for del_lf_rows and del_lf_rows_len.
