I am newbie in oracle and i want to get partition column name form partition name.
same query working in MySQL
:
SELECT PARTITION_EXPRESSION FROM INFORMATION_SCHEMA.PARTITIONS WHERE TABLE_SCHEMA = ? AND TABLE_NAME = ? limit 1
this query will give me partition column name, same output I want in oracle
My oracle create table query is look like this
CREATE TABLE part_char_date
(emp_no NUMBER(11) , birth_date date , first_name VARCHAR2(100),
last_name VARCHAR2(100) , gender CHAR(1) , hire_date DATE )
PARTITION BY RANGE ( hire_date )
INTERVAL(NUMTOYMINTERVAL(1, 'MONTH'))
(PARTITION p0 VALUES LESS THAN (TO_DATE('1-1-2007', 'DD-MM-YYYY')),
PARTITION p1 VALUES LESS THAN (TO_DATE('1-1-2008', 'DD-MM-YYYY')),
PARTITION p2 VALUES LESS THAN (TO_DATE('1-7-2009', 'DD-MM-YYYY')),
PARTITION p3 VALUES LESS THAN (TO_DATE('1-1-2010', 'DD-MM-YYYY')) )
now I want get partition column. any one help me
If you mean the partition key column then
SELECT OWNER, NAME, OBJECT_TYPE, COLUMN_NAME, COLUMN_POSITION FROM ALL_PART_KEY_COLUMNS WHERE NAME = 'PART_CHAR_DATE';
