Solving problems as a DBA....from James Koopmann..

Question

Many of you might have seen this. However, if you have not here it is. I found this pretty intersting and informative. We can base this idea into what we do --

Answer 1

Just doing some more digging - Perhaps someone can tell me if I'm heading in the write direction?
Should I be using a looping dbms_lob.writeappend step?
I found this example...
create table TEST(IDX int, TXT CLOB);
create or replace procedure P_TEST(P_IDX in number,P_TXT in varchar2,P_FLAG in number) as
g_clob clob;
begin
if P_FLAG=0 then
insert into test values (P_IDX, empty_clob() ) returning TXT into g_clob;
dbms_lob.write( g_clob,length(P_TXT), 1,P_TXT);
else
select TXT into g_clob from test where IDX=P_IDX for update;
dbms_lob.writeappend( g_clob, length(P_TXT), P_TXT);
end if;
end;
Will this do a job for me? Has anyone hit similar problems to this before?
Thanks for your time,
James
