Is it possible to create table with partition in compress mode

Question

Hi All,
I want to create a table in compress option, with partitions. When i create with partitions the compression isnt enabled, but with noramal table creation the compression option is enables.
My question is:
cant we create a table with partition/subpartition in compress mode..? Please help.
Below is the code that i have used for table creation.
CREATE TABLE temp
  TRADE_ID                    NUMBER,
  SRC_SYSTEM_ID               VARCHAR2(60 BYTE),
  SRC_TRADE_ID                VARCHAR2(60 BYTE),
  SRC_TRADE_VERSION           VARCHAR2(60 BYTE),
  ORIG_SRC_SYSTEM_ID          VARCHAR2(30 BYTE),
  TRADE_STATUS                VARCHAR2(60 BYTE),
  TRADE_TYPE                  VARCHAR2(60 BYTE),
  SECURITY_TYPE               VARCHAR2(60 BYTE),
  VOLUME                      NUMBER,
  ENTRY_DATE                  DATE,
    REASON                      VARCHAR2(255 BYTE),

First of all your CREATE TABLE statement is full of syntax errors. Next time test it before posting - we don't want to spend time on fixing things not related to your question.
Now, I bet you check COMPRESSION value of partitioned table same way you do it for a non-partitioned table - in USER_TABLES - and therefore get wrong results. Since compreesion can be enabled on individual partition level you need to check COMPRESSION in USER_TAB_PARTITIONS:
