Regarding CLOB datatype

Question

Hi,
I have two databases with sids' R2SRVR5.WORLD and R2SRVR3.WORLD
Now I have executed the follwoing in r2srvr5 database.
create table kou_test_1
roll integer,
clob_data clob
begin
insert into kou_test_1(roll,clob_data) values (2,empty_clob());
insert into kou_test_1(roll,clob_data) values (3,empty_clob());
commit;
end;
declare
v_clob clob := 'dfhgfjudhgjfhjdhgdhjghdjrjgjgjhfhjjgfyugfygfjgfjgfjgjygjyfgwfg
gfjygfjygfjuyuiryugyubgryuwbgrjyubgrjgrjywgerjgrgw
eukwgfuweyjyegfjgfjhrjujuhwruihri';
begin
update kou_test_1 set clob_data=v_clob where roll=3;
commit;
end;
Now I have created a table in r2srvr3 database.
create table kou_test_2
roll integer,
clob_data clob
and also created a database link from r2srvr3 to r2srvr5.
now when I am executing the following code it gives the error "ORA-22992: cannot use LOB locators selected from remote tables
ORA-06512: at line 2"
begin
insert into kou_test_2(roll,clob_data)
select roll,decode(roll,3,clob_data,empty_clob())
from [email protected];
commit;
end;
Now can any body provide me any solution of it except two separate inserts like
begin
insert into kou_test_2(roll,clob_data)
select roll,clob_data
from [email protected]
where roll=3;
commit;
end;
insert into kou_test_2(roll,clob_data)
select roll,null
from [email protected]
where roll<>3;
commit;
end;
Waiting for reply,
Regards,
