Problem with DBMS_LOB.

Question

Hi, I am working with Oracle XE, I created a table with the following structure:
CREATE TABLE "HR". EMPLOYEE_DOCUMENTS "
"NUM_DOCUMENS" ENABLE NUMBER NOT NULL,
"EMPLOYEE_COD" NUMBER (6.0) NOT NULL ENABLE,
"TIPO_DOCUMENTO" VARCHAR2 (12 BYTE) NOT NULL ENABLE,
"GENERADO_EL" DATE NOT NULL ENABLE,
"DOCUMENTO_BLOB" BLOB,
"DOCS8_CLOBS" CLOB,
CONSTRAINT "EMPLOYEE_DOCUMENTS_PK" PRIMARY KEY ( "NUM_DOCUMENS")
In the field CLOB stored as a text as follows:
A person who carries the card. # for the use of the credential # pursued by the law.
With DBMS_LOB, replacing the characters # content in the field CLOB by the value 1306958172, but the text that remains the last # concatenates and not get results like this:
A person who carries the card. 1306958172 for the use of the credential 1306958172 pur
One more question, as can assign field contents CLOb the type BLOB field to save as a Word document, an example please.
Tahnk.
Roberto.

Answer 1

In that place of my Store Procedure:
declare
clobs1 CLOB;
clobs2 CLOB;
BLOBS blob;
clobs_aux CLOB;
valor number;
cadena varchar2(4000);
nposicion number;
ncontar number:=1;
begin
select docs8_clobs, documento_blob into clobs1,blobs
from hr.EMPLOYEE_DOCUMENTS
where hr.EMPLOYEE_DOCUMENTS.NUM_DOCUMENS=12812;
valor:=DBMS_LOB.INSTR(CLOBS1,'#',1,ncontar);
clobs_aux:=clobs1;
while valor<>0 loop
nposicion:=valor+1;
DBMS_OUTPUT.PUT_LINE(TO_CHAR(VALOR));
clobs2:=DBMS_LOB.SUBSTR(clobs_aux,valor-1,1);
clobs2:=clobs2||' '||to_clob('1306958172');
clobs2:=clobs2||' '||DBMS_LOB.SUBSTR(clobs_aux,nposicion,nposicion);
CLOBS_AUX:=CLOBS2;
if ncontar>=1 then
update hr.EMPLOYEE_DOCUMENTS
set docs8_clobs=clobs_aux
where num_documens=12812;
commit;
end if;
--Recuperar campo CLOB actualizado.
select docs8_clobs, documento_blob into clobs1,blobs
from hr.EMPLOYEE_DOCUMENTS
where hr.EMPLOYEE_DOCUMENTS.NUM_DOCUMENS=12812;
CLOBS_AUX:=CLOBS1;
valor:=DBMS_LOB.INSTR(CLOBS_AUX,'#',1,ncontar);
ncontar:=ncontar+1;
end loop;
end;
