Ora-01406

Question

Lobs are often troublesome .
I have to fetch the concatenated result of few long varchar columns(all of them are of over 3888 bytes)  over a dblink from my staging schema . I have made a procedure to do this .
Similar to
create or replace function lob (par1 varchar2)return clob
as
l_clob  clob;
l_clob2 clob;
l_clob3 clob;
BEGIN
  select source_col1,source_col2,source_col3 into l_clob,l_clob2,l_clob3 from source_table_over_db_link where col1=par1;
return (lcob||l_cob2||l_clob3);
END;
when i simply call this function ,it works fine .i.e.
select lob('ABCC') from dual; Returns me result
But when i use this function inside another select statement as below
SELECT TO_CLOB(local_table.col1),to_clob(local_table.col2)||lob('ABCC') from local_table ;
I get the below ora error.
I get ORA-01406 .i.e. the fetched column value was truncated .
I am cluless ?  The version is 11.2.0.3.0 Production 64 bit Tns  for linus versio  11.2.0.3.0

OracleManiac,
This error is environment specific too and it also comes when we are using DB links. Which tool are you using?
If possible try it out from SQL*PLUS as well. If you are on TOAD, use this VIEW:OPTIONS:ORACLE:OCI buffer array size
You need to increase Buffer Array Size to fit your value.
