The DBA needs to create a table with key columns YEARMONTH and YEAR. This table needs to be partitioned by column YEARMONTH with three months per data partition. Additionally, data needs to be organized by column YEAR, so that all rows within any three month date range are clustered together based on 12 months of data. Which CREATE TABLE statement will accomplish this objective?
A. CREATE TABLE tab1
(yearmonth INT,
year CHAR(2))
PARTITION BY RANGE (yearmonth) (STARTING 201001 ENDING 201012 EVERY 12)
ORGANIZE BY DIMENSIONS (year))
B. CREATE TABLE tab1
(yearmonth INT,
year CHAR(2))
PARTITION BY RANGE (yearmonth) (STARTING 201001 ENDING 201012 EVERY 3)
ORGANIZE BY DIMENSIONS (year))
C. CREATE TABLE tab1
(yearmonth INT,
year CHAR(2))
PARTITION BY RANGE (year) (STARTING 201001 ENDING 201012 EVERY 12)
ORGANIZE BY DIMENSIONS (yearmonth))
