Server Administration :: How To See Whether Table Data Using Compression
Mar 13, 20131)i have 2 SWP TABLES. while dropping a column, i am getting error -
ORA-39726: unsupported add/drop column operation on compressed tables.
2) when i checked compression status, those were not compressed. But as per our code standard, SWP tables should not be in compress mode.
OWNER TABLE_NAME COMPRESS COMPRESS_FOR
------------------------------ ------------------------------ -------- ------------
NOVAR PAYMENT_SWP DISABLED
OWNER TABLE_NAME COMPRESS COMPRESS_FOR
------------------------------ ------------------------------ -------- ------------
NOVAR PREPAYMENT_SWP DISABLED
3) as a workaround, i compressed these 2 SWP tables with OLTP option, and then i was able to drop the column from these 2 SWP tables.
4) Below statement is correct or not ?
IF A TABLE USING BLOCK LEVEL COMPRESSION, THEN this error will come - ORA-39726: unsupported add/drop column operation on compressed tables.
if above statement is correct, then how to find out whether table data is using block level compression ?
5) we have DBMS_COMPRESSION.GET_COMPRESSION_TYPE. using this i just tried to find out, but i am getting "1" as output. I am not getting the exact meaning of it.
confirm what is the conclusion on this ?

View 3 Replies View RelatedServer Utilities :: Importing Data From SQL Server To Oracle?
Mar 7, 2011I'm importing data from SQL Server to Oracle. I used BCP to export the data from SQL Server. Below is the 1st record of table trlc from the csv file.
trlc.CSV
11032|100|Wman| | |2008-02-08| |
Using SQL Loader to import into Oracle:
TRLC table in Oracle database:
est_no varchar2(10) default ' '
right_no number(4) default 0
maj_auth varchar2(15) default ' '
weight varchar2(10) default ' '
idm_ht varchar2(8) default ' '
c_date date
P_tkt varchar2(5) default ' '
sqlldr user/pwd@db02 control=trlc.ctl log=trlc.log
trlc.ctL:
load data
infile 'trlc.csv'
replace
into table trlc
fields TERMINATED BY '|'
TRAILING NULLCOLS
(est_no,right_no,maj_auth,weight,idm_ht,c_date,P_tkt)
The rows get inserted successfully. But the result sets are different, for example: When I do a select in SQL Server,'select len(weight) from trlc;' , I get the length as 0. But when I do a select in oracle database, I get the length as 1. Also, the result set varies for the query below:
select * from trlc where weight=' ';
(SQL Server returns 1 row but Oracle returns no rows)
Do I need to mention any conversion code for the weight field to accept ' ' value?

Aug 8, 2012Hybrid Columnar Compression is dependent on the underlying storage system. See Oracle Database Licensing Information for more information.
The below is from the Oracle® Database PL/SQL Packages and Types Reference
Compression Constant Compression Level Description
COMP_FOR_OLTP 2 OLTP compression
COMP_FOR_QUERY_HIGH 4 High compression level for query operations
COMP_FOR_QUERY_LOW 8 Low compression level for query operations
COMP_FOR_ARCHIVE_HIGH 16 High compression level for archive operations
COMP_FOR_ARCHIVE_LOW 32 Low compression level for archive operations
To use Compression Level 4 or higher do we have to have ZFS or Pillar storage ?
