LOBs from afar

1–2 minutes

This has always been a nuisance.  There you are – getting all the bells and whistles with LOBs…until a database link enters the room Smile


--
-- Database: DB11
--
SQL> create table t ( id int, c clob );

Table created.

SQL> insert into t values (1,rpad('x',32000,'x'));

1 row created.

SQL> select * 
  2  from   t;

        ID C
---------- --------------------------------------------
         1 xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

--
-- Database: anywhere except DB11
--
SQL> select * 
  2  from   t@db11;

ERROR:
ORA-22992: cannot use LOB locators selected from remote tables

 

Well that sucks. But look what has snuck its way into 12.2 !


SQL> select * 
  2  from   t@db122;

        ID C
---------- --------------------------------------------
         1 xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

 

There is a whole chapter on it here in the official docs.  Very nice indeed.

    Awesome! I’m really keen on jumping the 12.1 release and off to 12.2 directly for most of our 11.2 dbs!
    So far all I’ve seen looks excellent!
