oracle關於*_tab_columns檢視的描述有一個錯誤

tengrid發表於2009-05-18

oracle10g docs <>P1016 有一處錯誤:
Note: The MAXVALUE and MINVALUE columns of USER_, DBA_,
and ALL_TAB_COLUMNS have a length of 32 bytes. If you analyze
columns with a length >32 bytes, and if the columns are padded
with leading blanks, then Oracle Database may take into account
only the leading blanks and return unexpected statistics.

在*_tab_columns中並沒有 MAXVALUE,MINvalue這兩個欄位.
