Clarification on CLOB column
Posted on 2014-09-24
I have an table called comments in the users_tab tablespace. We have decided to alter one of its column called
comments_desc from varchar2 to CLOB.
We have decided to use th CLOB data type for storing the comments. One technical question in regard to implementing it
1. We have decided to store the CLOB data in an tablespace other then the commentary table tablespace. I.e commentary table is in users_tab tablespace , we decided to create an new tablespace USER_LOB . My question here is how can i tell oracle to store the CLOB data in users_lob tablespace while altering the column comments_desc to clob datatype .
2. difference between regexp_like and like in oracle
3. While changing column data type can we instruct oracle to use the secure file features.
