Behaviour of insert ... select statement

Hi,
If we use insert ... select statement like
insert into TableA
Select
from TableB;
and if TableB have 250000 rows then what will be the action for it..
will all 250000 rows fetched to database buffer and if index scans are performed on it and then all rows inserted into TableA
or
it will do it parallel
We are loading large data and facing performance problems for delaying index scans.
Just Curious :)
Rushang.

it's not a secret. oracle will perform the select, using indexes if it decides to (depends on source table size, stats, optimizer mode, etc, etc). rows may be pulled back to memory be written to temp space (e.g., if you were returning many, many rows which needed to be grouped). the rows will then be inserted.
so, if you have an index on tableb.col1, then oracle may use the index. or it may do a FTS. either way, it will only select the needed rows to be inserted.
the insert does not prevent the select from working as it would normally.

Smart scan not working with Insert Select statements

We have observed that smart scan is not working with insert select statements but works when select statements are execute alone.
Can you please help us to explain this behavior?

There is a specific exadata forum - you would do better to post the question there: Exadata
I can't give you a definitive answer, but it's possible that this is simply a known limitation similar to the way that "Create table as select" won't run the select statement the same way as the basic select if it involves a distributed query.

Insert select statement or insert in cursor

hi all,
i need a performance compare for: insert operation in cursor one by one and select statement insert,
for example:
1. insert into TableA (ColumA,ColumnB) select A, B from TableB;
2. cursor my_cur is select A, B from TableB
for my_rec in my_cur loop
insert into TableA (ColumA,ColumnB) values (my_rec.A, my_rec.B);
end loop;
also "bulk collect into" can be used.
Which one has a better performance?
Thanks for your help,
kadriye

What's stopping you from making 100,000 rows of test data and trying it for yourself?
Edit: I was bored enough to do it myself.
Starting insert as select 22-JUL-08 11.43.19.544000000 +01:00

Thanks for your advices
Simon

The total density number for the MKT_OP_DBF.M_ORIGIN_NB column don't look very good:
     Range cell density:           0.0000034460903826
     Total density:                0.0053334921767125
Notice the total density value is 3 magnitudes larger than the range density ... which can indicate a largish number of duplicates. (NOTE: This wide difference between range cell and total density can be referred to as 'skew' - more on this later.)
Do some M_ORIGIN_NB values have a large number of duplicates? What does the following query return:
=====================
select top 30 M_ORIGIN_NB, count(*)
from   MKT_OP_DBF
group by M_ORIGIN_NB
order by 2 desc, 1
=====================
The total density can be used to estimate the number of rows expected for a join (eg, TRN_HDR_DBF --> MKT_OP_DBF). The largish total density number, when thrown into the optimizer's calculations, may be causing the optimizer to think that the volume of *possible* joins will be more expensive than a join in the opposite direction (MKT_OP_DBF --> TRN_HDR_DBF) which in turn means (as Jeff's pointed out) that you end up table scanning MKT_OP_DBF (as the outer table) because of no SARGs.
From your description it sounds like you've got the necessary indexes to support a TRN_HDR_DBF --> MKT_OP_DBF join order. (Though it wouldn't hurt to see the complete output from sp_helpindex for both tables just to make sure we're on the same sheet of music.)
Without more details (eg, complete stats for both tables, sp_help for both tables - if you decide to post these I'd recommend posting them as a *.txt attachment).
I'm assuming you *know* that a join from TRN_NDR_DBF --> MKT_OP_DBF should be much quicker than what you're currently seeing. If this is the case, I'd probably want to start with:
=====================
exec sp_modifystats MKT_OP_DBF, M_ORIGIN_NB, REMOVE_SKEW_FROM_DENSITY
go
exec sp_recompile MKT_OP_DBF
go
-- run your query again
=====================
By removing the skew from the total density (ie, set total density = range cell density = 0.00000344...) you're telling the optimizer that it can expect a much smaller number of joins for the join order of TRN_HDR_DBF --> MKT_OP_DBF ... and that may be enough for the optimizer to use TRN_HDR_DBF to drive the query.
NOTE: If sp_modifystats/REMOVE_SKEW_FROM_DENSITY provides the desired join order, keep in mind that you'll need to re-issue this command after each update stats command that modifies the stats on the M_ORIGIN_NB column. For example, modify your update stats maintenance job to issue sp_modifystats/REMOVE_SKEW_FROM_DENSITY for those special cases where you know it helps query performance.

Strange Behaviour for sequential SELECT statements

I have all my handles ready to be used
I do a StmtPrepare , StmtExecute , StmtFetch
I get (lets say) 3 results...
result is correct...
Then by using the very same handles
I do a StmtPrepare , StmtExecute , StmtFetch
I get (lets say) 3 results...
result is incorrect...
I should be getting 10 results but i get the first 3
If in the first pass i get 4 results then in the second
pass i get 4 results like the result_count_of_second = result_count_of_first !?????
I get no error or warning , everything seems OK
I check SQL statements from TOAD also
What may cause this and any trick to overcome ?
Should i free and realloc the StmdHandle ?
(I dont want to do this but !?)

Could you provide some snippets of the code that is
giving the problem?
What do you mean that you should be getting 10 results?
Are you getting an OCI_NO_DATA earlier than expected (on
the third row instead of the 10th)?
I think that if you gave some code snippets of your
OCI program and an example of what results you are
expecting and what results you are actually getting,
we might be in a better position to help.

Number of rows inserted is different in bulk insert using select statement

I am facing a problem in bulk insert using SELECT statement.
My sql statement is like below.
strQuery :='INSERT INTO TAB3
(SELECT t1.c1,t2.c2
FROM TAB1 t1, TAB2 t2
WHERE t1.c1 = t2.c1
AND t1.c3 between 10 and 15 AND)' ....... some other conditions.
EXECUTE IMMEDIATE strQuery ;
These SQL statements are inside a procedure. And this procedure is called from C#.
The number of rows returned by the "SELECT" query is 70.
On the very first time call of this procedure, the number rows inserted using strQuery is *70*.
But in the next time call (in the same transaction) of the procedure, the number rows inserted is only *50*.
And further if we are repeating calling this procedure, it will insert sometimes 70 or 50 etc. It is showing some inconsistency.
On my initial analysis it is found that, the default optimizer is "ALL_ROWS". When i changed the optimizer mode to "rule", this issue is not coming.
Anybody faced these kind of issues?
Can anyone tell what would be the reason of this issue..? any other work around for this...?
I am using Oracle 10g R2 version.

You have very likely concurrent transactions on the database:
>
By default, Oracle Database permits concurrently running transactions to modify, add, or delete rows in the same table, and in the same data block. Changes made by one transaction are not seen by another concurrent transaction until the transaction that made the changes commits.
>
If you want to make sure that the same query always retrieves the same rows in a given transaction you need to use transaction isolation level serializable instead of read committed which is the default in Oracle.
Please read http://download.oracle.com/docs/cd/E11882_01/appdev.112/e10471/adfns_sqlproc.htm#ADFNS00204.
You can try to run your test with:
set transaction isolation level serializable;If the problem is not solved, you need to search possible Oracle bugs on My Oracle Support with keywords

Select Statement takes more time after immediate insert statement..

Hello,
I found below scenario
1. I have table TABLE1 which has index on COL1 field. It has around 40 columns and 100000 rows.
2. whenever i insert 100000 rows in bulk with changing indexed key column and executing SELECT statement in same session then it takes around 3 mins to complete.
3. However, if i open new session and execute same select statement then it returns in 2-3 seconds.
I didnt get anything in XPLAN.. :(
I felt Buffer Clean is cause to take time. please let me know your opinion.
Thanks in Advance

Can you change this:
BETWEEN '01-Mar-2009'
AND '31-Mar-2009'To this:
BETWEEN TO_DATE('01-Mar-2009', 'DD-MON-YYYY')
AND TO_DATE('31-Mar-2009','DD-MON-YYYY')That may make no difference but you should never rely on implicit conversions like that, they're always likely to cause you nasty surprises.
If you're still getting the discrepancy, instead of and INSERT-SELECT, can you try a CREATE TABLE AS SELECT... just to see if you get the same result.

Only select statements work (update/insert hang)

Hi, I am running CF MX version 7,0,2,142559 Standard Edition
and ColdFusion is hanging everytime I attempt an insert or update
statement again Oracle 8i and 9i using the jdbc thin driver and an
odbc socket driver.
Select statements work fine. I have tried everything I could
think of and I get the same results. All rights are given to the
datasource and the user. I can do insert and update statement via
another application (Toad) with the same Oracle user.
Any suggestions??? I don't see any hot fixes for this but
that doesn't mean one doesn't exist.
Also, many times it causes the system cpu utlization to stick
at 100% until I restart ColdFusion.
Thanks for any help.

Hi,
I had similar results on Oracle 10G while using cfmx 7.02. I
actually updated the macromedia_drivers.jar from the coldfusion
support site.
http://www.adobe.com/cfusion/knowledgebase/index.cfm?id=42dcb10a
An update to the datadirect JDBC drivers. Try that. If not,
make sure you have the latest JDBC drivers from Oracle. Since
previous versions would make the update/insert;s hang.

SELECT - INSERT/UPDATE statement mapping.

This might be a silly question, but are there any Java libraries that can perform an arbitrary SELECT statement to INSERT/UPDATE statement mapping? Or indeed, is this in fact possible?
Just to be a little clearer, if we had the statement;
SELECT [Field1] FROM [Table1]
It would map down to;
INSERT INTO [Table1] VALUES [Field1]='foo'
Please excuse my INSERT syntax if it is incorrect, I hardly ever use these statements.
The reason that I ask is because I am writing a piece of software that can perform quite complex extractions from databases, and it would be nice to be able to automatically 'reverse' the extraction, and perform updates on the extracted data.
Unfortunately, because of the architecture and requirements of the application, I can not just update a resultset and call the update() method.
Thanks for your time.
Ben

You can define a Bean or simple class to define a table record type (table structure), defining all fields, the primary key and maybe more.
then deriving a select or insert or update can be done with ease.

How to pass values in select statement as a parameter?

Hi,
Very simple query, how do I pass the values that i get in the cursor to a select statement. If table1 values are 1,2,3,4 etc , each time the cursor goes through , I will get one value in the variable - Offer
So I want to pass that value to the select statement.. how do i do it?
the one below does not work.
drop table L1;
create table L1
(col1 varchar(300) null) ;
insert into L1 (col1)
select filter_name from table1 ;
SET SERVEROUTPUT ON;
DECLARE
offer table1.col1%TYPE;
factor INTEGER := 0;
CURSOR c1 IS
SELECT col1 FROM table1;
BEGIN
OPEN c1; -- PL/SQL evaluates factor
LOOP
FETCH c1 INTO offer;
EXIT WHEN c1%NOTFOUND;
DBMS_OUTPUT.PUT_LINE(offer);
select * from table1 f where f.filter_name =:offer ;
factor := factor + 1;
DBMS_OUTPUT.PUT_LINE(factor);
END LOOP;
CLOSE c1;
END;

Hi User,
You are looking somethuing like this, as passing the values to the Cursor as a Paramter.
DECLARE
   CURSOR CURR (V_DEPT IN NUMBER)    --- Cursor Declaration which accepts the deptno as parameter.
   IS
      SELECT *
        FROM EMP
       WHERE DEPTNO = V_DEPT;    --- The, Input V_DEPT is passed here.
   L_EMP   EMP%ROWTYPE;
BEGIN
   OPEN CURR (30);       -- Opening the Cursor to Process the Value for Department Number 30 and Processing it with a Loop below.
   DBMS_OUTPUT.PUT_LINE ('Employee Details for Deptno:30');
   LOOP
      FETCH CURR INTO L_EMP;
      EXIT WHEN CURR%NOTFOUND;
      DBMS_OUTPUT.PUT ('EMPNO: ' || L_EMP.EMPNO || ' is ');
      DBMS_OUTPUT.PUT_LINE (L_EMP.ENAME);
   END LOOP;
   CLOSE CURR;
   DBMS_OUTPUT.PUT_LINE ('Employee Details for Deptno:20'); -- Opening the Cursor to Process the Value for Department Number 20
   OPEN CURR (20);
   LOOP
      FETCH CURR INTO L_EMP;
      EXIT WHEN CURR%NOTFOUND;
      DBMS_OUTPUT.PUT ('EMPNO: ' || L_EMP.EMPNO || ' is ');
      DBMS_OUTPUT.PUT_LINE (L_EMP.ENAME);
   END LOOP;
   CLOSE CURR;
END;Thanks,

Hi Greg,
Thanks for the response, No there is no ODB.net involved here.
If I remove the : from :offer. I get this error now.
Changed SQL is:
select * from table1 f where f.filter_name =offer ;
Error report:
ORA-06550: line 16, column 23:
PL/SQL: ORA-00942: table or view does not exist
ORA-06550: line 16, column 9:
PL/SQL: SQL Statement ignored
06550. 00000 - "line %s, column %s:\n%s"
*Cause: Usually a PL/SQL compilation error.
*Action:

Behaviour of insert ... select statement
