LONG column Manipulation

Question

Hi,
I want to put a message at a paricular position in a long column like
LONG Value Part1 ||message || LONG Value Part2.
As every body knows i can't use SUBSTR for the same since the Data Type is long and at the same time i can't change the dataType also.
So requesting you to provide some solution.....
Thanks

Answer 1

You want something like this ?
SQL> Create table with_long (long_dt LONG);
Table created.
SQL>  insert into with_long values('This is a long datatype');
1 row created.
SQL> declare
  2  l_tmp long;
  3  l_str long;
  4  begin
  5  select long_dt into l_tmp from with_long;
  6  l_str:=substr(l_tmp,1,10)||' long '||substr(l_tmp,14);
  7  insert into with_long values(l_str);
  8  end;
  9  /
PL/SQL procedure successfully completed.
SQL> select * from with_long;
LONG_DT
This is a long datatype
This is a  long g datatypeAlso you might want to consult Oracle Documentation and Metalink/Asktom for examples.
By the way, If your long value is more than 32k then just convert it into lob and use the same approach.
