Question :
I am currently migrating all the tables in my database to a bigfile tablespace. I have written a script to do this and all tables are migrated successfully except one. I am given the error:
Error report:
SQL Error: ORA-00997: illegal use of LONG datatype
00997. 00000 – “illegal use of LONG datatype”
And I am converting the tablespaces by:
alter table mytable move tablespace bigfile_tablespace;
Changing the column type isn’t an option.
I have a script that creates all the tablespace from scratch using bigfile and it goes through fine with this table so I am little stuck on this…
Answer :
To move the table without changing the column datatype I believe you’ll need to export the table then import it into the new tablespace.
Note that if you’re using Oracle 10g or later use expdp and impdp instead of exp/imp. (See: http://docs.oracle.com/cd/B19306_01/server.102/b14215/dp_export.htm)
You should use a command like:
exp file=mytable.dmo log=mytable .log tables=mytable feedback=1
To export the table. Then drop it in the old tablespace and create it in the new tablespace.
Then use:
imp file=mytable.dmo log=mytable.log full=y feedback=1 ignore=y
To import the table. Hope this helps.
