CLOB Datatype (Assgin more than 32k fails)

Question

Dear All
Can anyone tell me why i am getting this error if i assign more than 32k character to clob variable in pl/sql
but i can assign it from table to a variable
Pl/sql 1(ORA-06502: PL/SQL: numeric or value error: character string buffer too small)
declare
c clob;
v varchar(32767);
begin
for i in 1..90000 (just assuming it as 90k)
loop
v:=v||'x';
if length(v) > 31000 then
c:=c||v; -- here iam getting error while assigning character to clob if it is more than 32k
v:=null;
end if;
end loop;
c:=v;
end;
Pl/sql 2 (works fine when assgin from table)
declare
c clob;
begin
select clob_data into c from x; -- clob data is more than 32k;
end;
But it works fine with database 9i rel2 but in 11g i am facing this problem.
Regards

Answer 1

hey U r getting the error because of v varchar(32767) , but clob data type can take large amont of data atleast 1000000 this much data can be stored in clob data type try it with this. or else see below
Hi see the example below
create table temp(col clob);
declare
v_string clob;
begin
for i in 1..1000000
v_string:=v_string||'A';
end loop;
insert into temp values(v_string);
end;
now
select length(col) from temp; you will get output as
length(col)
1000000
this means that clob datatype can store minimum of 1000000 character.
