The INV_HISTORY table is created using the command： SQL>CREATE TABLE INV_HISTORY （inv_no NUMBER（3）， inv_date DATE， inv_amt NUMBER（10，2）） partition by range （inv_date） interval （numtoyminterval（1，’month’）） （partition p0 values less than （to_date（’01-01-2005’，’dd-mm-yyyy’））， partition p1 values less than （to_date（’01-01-2006’，’dd-mm-yyyy’）））； The following data has been inserted into the INV_HISTORY table ： INV_NO INV_DATE INV_AMT 1 30-dec-2004 1000 2 30-dec-2005 2000 3 1-feb-2006 3000 4 1-mar-2006 4000 5 1-apr-2006 5000 You would like to store the data belonging to the year 2006 in a single partition and issue the command： SQL> ALTER TABLE inv_history MERGE PARTITIONS FOR（TO_DATE（’15-feb-2006’，’dd-mon-yyyy’））， FOR（TO_DATE（’15-apr-2006’）） INTO PARTITION sys_py； What would be the outcome of this command？（）
- A It executes successfully，and the transition point is set to ’1-apr-2006’.
- B It executes successfully，and the transition point is set to ’15-apr-2006’.
- C It produces an error because the partitions specified for merging are not adjacent.
- D It produces an error because the date values specified in the merge do not match the date values stored in the table.
