Forall ...........loop
Hi All,
I am using forall loop as below
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
CREATE TYPE coords AS object(x NUMBER,y NUMBER);
CREATE TABLE a_temp (
n NUMBER NULL,
cr COORDS NULL
DECLARE
TYPE cur1 IS TABLE OF a_temp%ROWTYPE;
cur_var1 cur1;
BEGIN
SELECT * BULK COLLECT INTO cur_var1 FROM a_temp;
/*FOR i IN cur_var1.first..cur_var1.last LOOP
Dbms_Output.put_line(cur_var1(i).n||'-'||cur_var1(i).cr.x||','||cur_var1(i).cr.y);
END LOOP;*/
FORALL i IN cur_var1.first..cur_var1.last
INSERT INTO C_TEMP(n) VALUES(cur_var1(i).n);
END;
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
but geting below error:
ORA-06550: line 13, column 32:
PLS-00436: implementation restriction: cannot reference fields of BULK In-BIND table of records
ORA-06550: line 13, column 32:

Please comment.......................
Thanks
Harry
Yes that we are able to do what is given in the link but what I am doing is ...
create a object type and using that in my table as column and then want to insert that data in another table that is giving error..
complete code is given as I am doing........
Please suggest in that code ...what is going wrong????
Thanks,

LOOP inside FORALL in bulk binding
Can I use a loop inside forall in bulk bind updates?
as I understand, forall statement strictly loops through the length of the bulk limit size for the immediately following statement only.
I am attempting to use a loop there to update more than one table.
cursor c is select id from temp where dt_date > sysdate-30;
BEGIN
loop
fetch c into v_id;
limit 1000;
forall i in 1..v_id.count
UPDATE table_one set new_id = v_id(i);
exit when C%NOTFOUND;
end loop;
end;
I want to update another table table_two also immediately after updating table_one like this:
forall i in 1..v_id.count
UPDATE table_one set new_id = v_id(i);
BEGIN select nvl(code,'N/A') into v_code from T_CODES where ID_NO = v_id(i); EXCEPTION WHEN NO_DATA_FOUND v_code='N/A'; END;
UPDATE table_two set new_code =v_code;
exit when C% not found.
This is not working and when I run it, I get an error saying encountered BEGIN when one of the following is expected.
I got around this by having another FOR loop just to set up the values in another array variable and using that value in another second forall loop to update table_two.
Is there any way to do this multiple table udpates in bulkbinding under one forall loop that would enable to do some derivation/calculation if needed among variables [not array variables, regular datatype variables].
Can we have like
forall j in 1.. v_id.count
LOOP
update table 1;
derive values for updating table 2;
update table 2;
END LOOP;
Thank You.Well, without questioning reasions why do you want this, you are confusing bulk select and forall. You need:
begin
loop
fetch c bulk collect into v_id limit 1000;
exit when v_id.count = 0;
forall i in 1..v_id.count
UPDATE table_one set new_id = v_id(i);
end loop;
end;

SimonI tried using a normal for loop instead of a forall loop (see code below). But this came up the error also see below. Or can I not use selects in this way???

Please help.
ThanksAnd what are you trying to do? You are updating column20 in all rows in table_1 over and over. And what is array_line? Type type_table_1 is not a table of objects, so what is tab_1(ctr).concat_column? Without questioning code logic (although I already did :) ), remove that ".concat_column":
set column_20 = array_line(tab_1(ctr));SY. -
How to use BULK COLLECT, FORALL and TREAT
There is a need to read match and update data from and into a custom table. The table would have about 3 millions rows and holds key numbers. BAsed on a field value of this custom table, relevant data needs to be fetched from joins of other tables and updated in the custom table. I plan to use BULK COLLECT and FORALL.
All examples I have seen, do an insert into a table. How do I go about reading all values of a given field and fetching other relevant data and then updating the custom table with data fetched.
Defined an object with specifics like this
CREATE OR REPLACE TYPE imei_ot AS OBJECT (
recid NUMBER,
imei VARCHAR2(30),
STORE VARCHAR2(100),
status VARCHAR2(1),
TIMESTAMP DATE,
order_number VARCHAR2(30),
order_type VARCHAR2(30),
sku VARCHAR2(30),
order_date DATE,
attribute1 VARCHAR2(240),
market VARCHAR2(240),
processed_flag VARCHAR2(1),
last_update_date DATE
Now within a package procedure I have defined like this.
type imei_ott is table of imei_ot;
imei_ntt imei_ott;
begin
SELECT imei_ot (recid,
imei,
STORE,

AND msi.organization_id =
(SELECT organization_id

WHERE NAME = 'Item Master'
AND source_lang = USERENV ('LANG'))
AND stg.imei = col.serial_number
AND stg.processed_flag = 'U');
/* Update staging table in one go for COR order data */
FORALL indx IN 1 .. imei_ntt.COUNT

THEN
DBMS_OUTPUT.put_line ('No Data: ' || SQLERRM);
WHEN OTHERS
THEN
DBMS_OUTPUT.put_line ('Other Error: ' || SQLERRM);
END;
Now for the unfortunate part. When I compile the pkg, I face an error
PL/SQL: ORA-00904: "LAST_UPDATE_DATE": invalid identifier
I am not sure where I am wrong. Object type has the last update date field and the custom table also has the same field.
Could someone please throw some light and suggestion?
Thanks
udsI suspect your error comes from the »bulk collect into« and not from the »forall loop«.
From a first glance you need to alias sysdate with last_update_date and some of the other select items need to be aliased as well :
But a simplified version would be
select imei_ot (stg.recid,
stg.imei,
cip.store_location,
'S',
co.rtl_txn_timestamp,
co.rtl_order_number,
'CUST',
msi.segment1 || '.' || msi.segment3,
trunc (co.txn_timestamp),
col.part_number,
'ZZ',
stg.processed_flag,
sysdate
bulk collect into imei_ntt
from custom_orders co,
custom_order_lines col,
custom_stg stg,
mtl_system_items_b msi
where co.header_id = col.header_id
and msi.inventory_item_id = col.inventory_item_id
and msi.organization_id =
(select organization_id
from hr_all_organization_units_tl
where name = 'Item Master' and source_lang = userenv ('LANG'))
and stg.imei = col.serial_number
and stg.processed_flag = 'U';

How to bypass FORALL in SELECT .. BULK COLLECT
Using Oracle 8.1.7
I developed a stored procedure LOT
TYPE TIds IS Table of Integer;
TYPE TFloats IS Table of Float;
procedure LOT(Ids TIds) ....
is
Prices TFloats;
Quantities TFloats;
begin
for I in 1..Ids.Count loop
SELECT ...
BULK COLLECT INTO Prices, Quantities, ...
WHERE ... = Ids(I)
end loop;
end;
For each Id from IDS collection my procedure SELECTs several
rows (avg. 2 or 3 rows). IDS contains about 1000 - 10000 items.
Productivity is very low.
Because is the many context switches
between SQL engine and PL/SQL engine.
The point is to collect all data by single 'huge' SELECT instead
of numerous 'short' SELECTs.
I. e. I need somethng like
FORALL I in 1..Ids.Count
SELECT ...
BULK COLLECT INTO Prices, Quantities, ...
WHERE ... = Ids(I)
or like this
FORALL I in 1..Ids.Count
SELECT ...
WHERE ... = Ids(I) RETURNING ... BULK COLLECT INTO ...
I know it's invalid syntax because PL/SQL doesn't support BULK
COLLECT clause for SELECT in FORALL loop.
How should I bypass the problem?
Is a proper way to use temporary table as storehouse for IDS collection?
Something else?
Regards,
Piter Elagin (AlienZzzz)Hi Ivan,
the problem is that the port is configurable at installation time. On a NetWeaver 04 portal, I believe the default was 50000. That should get you to one of the servers. You may try 50100, 50200, etc.
You can also ask who ever did the installation. the other place to look is the webdispatcher configuration file. It would have to know the server and port to dispatch to.
Hope that helps.

Problem with Bulk Collect ... FORALL
I've written following code to bulk collect records from a cursor into a collection and insert it into a table using FORALL loop
OPEN x;
LOOP
FETCH x BULK COLLECT INTO v_collection LIMIT 1000;
FORALL i IN 1..v_collection.count
INSERT INTO tablename(column1, column2) VALUES(v_collection(i).val1, v_collection(i).val2);
COMMIT;
EXIT WHEN x%NOTFOUND;
END LOOP;I have verified that query which is executed by cursor returns records but when my procedure is executed the insert statement inside the FORALL loop never executes. Am I missing something over here?
Regards,
FahadYes, the cursor is returning a row.
I've found the solution myself. There was a trigger which was deleting data on commit. Due to this, the records were not inserting. -
Hi Guys,
I have a forall statement that I want to continue processing if it hits an exception, and rollback anything it fails on. I have limits set so I am only lifting 300 records at a time, but if only one record fails in the forall, then i want the other 299 to process and commit, and only rollback that one failure..is it possible? This is using oracle 10g.
Example snippet below, the "dots" are just were I have removed unneeded code for this example. I want to know if I can add a rollback in the EXCEPTION that will rollback the forall failure for the one saved exception, and the "commit" will commit the remaining 299 that were success?
BEGIN
LOOP
FETCH cursor1
BULK COLLECT INTO table1 LIMIT 300;
IF table1.COUNT > 0
THEN
BEGIN
FORALL i IN 1 .. table1.COUNT SAVE EXCEPTIONS
END IF;
EXIT WHENtable1.COUNT = 0;
table1.DELETE;
END LOOP;
CLOSE cursor1;
COMMIT;
EXCEPTION
WHEN OTHERS
THEN
ROLLBACK;
END;
Edited by: fixxxer on 13-Oct-2011 01:36You can not do INSERT and DELETE using same FORALL statelemt. For that you have to create seperate copy of Collection.
If you want to ROLLBACK everything thnen omit the SAVE EXCEPTION statement in FORALL.
You can gothrough below FORALL restriction...
Restrictions
The following restrictions apply to the FORALL statement:
•You cannot loop through the elements of an associative array that has a string type for the key.
•Within a FORALL loop, you cannot refer to the same collection in both the SET clause and the WHERE clause of an UPDATE statement. You might need to make a second copy of the collection and refer to the new name in the WHERE clause.
•You can use the FORALL statement only in server-side programs, not in client-side programs.
•The INSERT, UPDATE, or DELETE statement must reference at least one collection. For example, a FORALL statement that inserts a set of constant values in a loop raises an exception.
•When you specify an explicit range, all collection elements in that range must exist. If an element is missing or was deleted, you get an error.
•When you use the INDICES OF or VALUES OF clauses, all the collections referenced in the DML statement must have subscripts matching the values of the index variable. Make sure that any DELETE, EXTEND, and so on operations are applied to all the collections so that they have the same set of subscripts. If any of the collections is missing a referenced element, you get an error. If you use the SAVE EXCEPTIONS clause, this error is treated like any other error and does not stop the FORALL statement.
•You cannot refer to individual record fields within DML statements called by a FORALL statement. Instead, you can specify the entire record with the SET ROW clause in an UPDATE statement, or the VALUES clause in an INSERT statement.
•Collection subscripts must be just the index variable rather than an expression, such as i rather than i+1.
•The cursor attribute %BULK_ROWCOUNT cannot be assigned to other collections, or be passed as a parameter to subprograms. -
Hi All
I am having an issue in my FORALL loop and I am thinking that I might not understand this properly.
Basically I am just updating a date in a table but the dates have timestamps. I trunc the date but the column always ends up as null.
code is simple
cursor list is select date from table1;
open list
fetch list bulk collect into l_date
forall i in 1.. 100
update table2 set date = trunc(l_date(i)) where id = id(i);
end loop
close list
notice the trunc inside my forall loop. it seems to null this value.
Is this behaviour correct?
Thanks in advanceclueless wrote:
The code was just to show what I was doing.
I understand using the word date is bad practice. What I am after is why the value in the FORALL loop ends up being null.
Outside the FORALL loop the trunc(date) would just round to the nearest day.
cursor list is select id, effdate from table1;
open list
fetch list bulk collect into l_effdateI believe this is not the real code.
what is l_effdate type ?
forall i in 1.. 100
update table2 set effdate = trunc(l_effdate(i)) where id = id(i);
end loop
close list
have you make sure the value of (l_effdate(i)) is not null? try to show with dbms_output.put_line
change your forall with for loop if you want to run debug for testing.
if your fetch is correct, it will give you exact same result -
Two DML operations in one FORALL?
Hi all,
In 11g is it possible to make two dml operations in one Forall loop?
For example:
SQL> create table xx_test (col1 number, col2 number, col3 number);
Table created
SQL> create table xx_test1 (col1 number, col2 number, col3 number);
Table created
SQL> insert into xx_test values(1,2,3);
1 row inserted
SQL> insert into xx_test values(1,2,3);
1 row inserted
SQL> insert into xx_test values(4,5,6);
1 row inserted
SQL> insert into xx_test1 values(6,7,8);
1 row inserted
SQL> declare
2 cursor c is select col1, col2, col3 from xx_test;
3 type t is table of c%rowtype;
4 v t;
5 begin
6 open c;
7 loop
8 fetch c bulk collect into v limit 1000;
9 forall i in 1..v.count
10 update xx_test1
11 set col1 = v(i).col2;
12
13 insert into xx_test1(col1,col2,col3) values(v(i).col1,v(i).col2,v(i).col3);
14
15 exit when c%notfound;
16 end loop;

PL/SQL: SQL Statement ignoredany ideas? I know that this can be achieved by processing row by row but in my case the cursor retrieves a lot of rows...
Thanks in advance,
Alexander.Stew, a bulk bind from an OCI client looks as follows:
OCIStmtPrepare()
OCIBindByName()/OCIBindByPos() (binding a host array)
while some-condition loop
fill host array
OCIStmtExecute() (specify the number of elements in array via the iters param)
end loopThe statement is executed once for each array element - according to the OCI guide. So in the case of sending a 100 elements, the statement will be executed (iterated) by Oracle, a 100 times. It however is not exactly clear on how the server-side deals with this execution.
The issue you raised with cursor execution counts, seems to be whether the statement is single statement, or single statement with nested statements.
I have written an OCI client doing the exact same tests as were done in PL/SQL using FORALL in this thread.
If the SQL statement executed is SQL, the cursor that is created is executed only "once" (not exactly true as multiple rows are inserted using a single row DML).
If the statement is PL/SQL, the cursor that is created, is executed "once". So pretty much the same behaviour. However, as this statement contains "nested" SQLs (the actual DML statements), these also need to be parsed and executed as cursors. In which case you see these as being executed a 100 times (once per element in for the bind array).
The issue is whether or not the FORALL DML statement is executed once (as it would appear from the executions column), or not?
It would seem that there is some funky happening (some kind of call optimisation perhaps?) when Oracle deals with an array bind - as the cursor seems to be executed once. But that in fact is not the case as that cursor only inserts a single row. And multiple rows are inserted.
E.g. simplistic example to see how many times the FORALL DML statement is executed:
SQL> create sequence emp_id_seq
2 start with 1
3 increment by 1
4 nocycle
5 nomaxvalue;
Sequence created.
SQL> --// add a PL/SQL user function wrapper for the sequence
SQL> create or replace function GetNextEmpID return number is
2 id number;
3 begin
4 select emp_id_seq.NextVal into id from dual; --// explicit SQL statement
5 return( id );
6 end;
7 /
Function created.
SQL>
SQL> declare
2 cursor c is
3 select empno, ename, job from emp;
4
5 type TBuffer is table of c%RowType;
6 buffer TBuffer;
7 begin
8 open c;
9 loop
10 fetch c bulk collect into buffer limit 100;
11
12 forall i in 1..buffer.Count
13 insert into tab1 values( GetNextEmpID(), buffer(i).ename );
14 exit when c%NotFound;
15 end loop;
16 close c;
17 end;

EXECUTIONS SQL_TEXT
14 SELECT EMP_ID_SEQ.NEXTVAL FROM DUAL
1 INSERT INTO TAB1 VALUES( GETNEXTEMPID(), :B1So the insert seems to have been executed once. However, the wrapper was called 14 times and its SQL statement was called 14 times. Once per bind array value.
So there do seem to be some kind of optimisation on the Oracle side - however, it does not mean that the FORALL statement is not using bulk/array binding. It is. And that is what the FORALL statement is designed to do. -
Can we use dbms_output.put_line package with forall statement
Hello Everybody
Can we use dbms_output.put_line package with forall or can we use insert,update and delete only
declare
type emp_rec is table of emp%rowtype
index by binary_integer;
t emp_rec;
begin
select * bulk collect into t from emp;
forall i in t.first..t.last
dbms_output.put_line(t(i).name);
end;Thanks & Regards

Well as the docs explain (though not very clear and detailed, I admit) you can use a dynamic sql statement (execute immediate) with FORALL.You got me interested in the performance side doing this Michael - running PL/SQL code via a FORALL loop.
It is faster than using a normal FOR loop to execute dynamic PL/SQL - a bit surprising as I expected another context switch to be in there. But seems like the PL/SQL engine is a more clever at optimisation than what I originally credited it with.. ;-)
Of course - pre-compiled/static PL/SQL code in a FOR loop is the fastest, as expected.

How to view errors if bulk collect has thrown errors
Hi,
I have few questions.
1.How to view error whether bulk collect is successful or not
2.What is identified & unidentified relationships in ERWIN
3.How to see the errors whether the sql loder is successful or not
and how to open the log file.Is there any specific command in UNIX
which tells loader is successful or thrown error
4.When executing the pl/sql procedure from UNIX.how to check for errors.
Please provide the answers for this
ThanksUse SAVE EXCEPTIONS clause in your FORALL loop.
Is this for homework/test?
