Ora - 22905

Question

Dear All,
I have one function as follows;
CREATE OR REPLACE TYPE split_tbl IS TABLE OF number;
CREATE OR REPLACE FUNCTION split (p_list VARCHAR2, p_delim VARCHAR2:=' ') RETURN SPLIT_TBL PIPELINED IS
l_idx    PLS_INTEGER;
l_list   VARCHAR2(32767) := p_list;
l_value  VARCHAR2(32767);
BEGIN
LOOP
l_idx := INSTR(l_list, p_delim);
IF l_idx > 0 THEN
PIPE ROW(SUBSTR(l_list, 1, l_idx-1));
l_list := SUBSTR(l_list, l_idx+LENGTH(p_delim));
ELSE
PIPE ROW(l_list);
EXIT;
END IF;
END LOOP;
RETURN;
END SPLIT;
Now I am createing new function as follows;
create or replace function sm_imagetext_data (mstring in varchar2)
return blob
is
cursor c1 is
select COLUMN_VALUE from table(split(mstring,','));
l_sm_imagetextid number;
l_data blob;
l_data1 blob;
begin
open c1;
loop
fetch c1 into l_sm_imagetextid;
--select COLUMN_VALUE into l_sm_imagetextid from table(split(mstring,','));
select data into l_data from sm_imagetext where sm_imagetextid = l_sm_imagetextid ;
l_data1 := l_data;
end loop;
return l_data1;
--close c1;
end;
But while executing
select sm_imagetext_data('7,8') from dual;
I received ORA -22905 error.
why this errors occoured.
Thanks in advance.

Answer 1

create or replace function sm_imagetext_data (mstring
in varchar2)
return blob
Here the return is BLOB
select sm_imagetext_data('7,8') from dual;SQL*Plus can't handle BLOBs.
Use DBMS_LOB package to do something for LOBs.
