Adding Compression to existing table - response (10) by sanjeevs

And if you want to add more values to the existing Compression List, you can do it as under :     ALTER TABLE DBA_TEST_DB.TEST_COMPRESSION ADD  column_b DECIMAL(15,2) COMPRESS ( 0.00, 0.20 ) ,ADD column_C DECIMAL(15,2) COMPRESS (0.00, 0.30 );     => remember to include the existing values also with this command else they will be overwritten with new values.     --Cheers
