Oracle table statistics

Dear All Members,
Is there any way where we can check whether current statistics in table are outdated in oracle? In OTN i found using view "DBA_TAB_MODIFICATIONS" we can gather timestamps of statistics
But can we use this to compare the quality of statistics in DB tables?
Regards,
Shanaka.

Hi Shanaka,
As far as I know that the DBA_TAB_MODIFICATIONS table used to collect quality of statistics value by SAP, also. There's only one exception that at the first step, without paying an attention to the DBA_TAB_MODIFICATIONS records, the system creates new statistics by using "-f stats -t all" parameters. At the second and further steps, new stats will be created for the tables that are need to be collected.
In short, because of the DB20 transaction reflects DBA_TAB_MODIFICATIONS table to store quality of the table stats, both values should be same.
In addition to the information above, you can read the notes, below;
Note 588668 - FAQ: Database statistics
Note 408527 - Checking the statistics using DBA_TAB_MODIFICATIONS,
Best regards,

Table Statistics Gathering Query

Hey there,
I'm currently getting trained in Oracle and one of the questions posed to me were create a table, insert a million rows into it and try to find the number of rows in it. I've tried the following steps to solve this,
First table creation
SQL> create table t1(id number);
Table created.Data insertion
SQL> insert into t1 select level from dual connect by level < 50000000;
49999999 rows created.Gathering statistics
SQL> exec dbms_stats.gather_table_stats('HR','T1');
PL/SQL procedure successfully completed.Finally counting the number of rows
SQL> select num_rows from user_tables where table_name='T1';
NUM_ROWS
49960410
SQL> select count(*) from t1;
COUNT(*)
49999999My database version is,
SQL> select * from v$version;

Please do keep in mind that i'm studying oracle and this is from a conceptual point of view only. I would like to know how gathering the table statistics works using dbms_stats package works.
Thank You,

Thank You,
VishalBecause you aren't specifying a value for estimate_percent in the procedure call (to gather_table_stats) Oracle will pick an estimate value for you. If you want to sample the entire table you would need to explicitly specify that in your procedure call.

Table statistics delete

Hi
Is there any command to delete gathered statistics of a table
suppose : I have gather table statistics as under
exec dbms_stats.gather_table_stats('TEST1','EMP');
now I want to delete the statistics from the above table EMP
Regards
Jewel

The package dbms_stats is fully documented in the Oracle supplied package and type reference manual for your unknown version of Oracle.
It has a call to delete statistics.
As per forums etiquette, please do the obvious first and consult documentation.

Gather Table Statistics (Stats) Crashing Application

Hello
Just started a new place of work which has a 9i database with a VB Front End App.
Noticed in the Database no stats had been gathered for any objects (ever).
I decided to run a gather stats procedure on a particular heavily-used table but it caused the application to crash/freeze?
begin
dbms_stats.gather_table_stats(OWNNAME=> , TABNAME=> ,
ESTIMATE_PERCENT=> dbms_stats.auto_sample_size,
METHOD_OPT=> 'FOR ALL COLUMNS SIZE 1', CASCADE=>TRUE);
end;
I decided to use auto sample size and decided to also gather stats on indexes (and without CASCADE=FALSE) but appeared to crash the application. The job itself worked fine.
Anyone ever encountered such issue? Could there be any reason for this (i.e. no stats ever gathered)?
Thanks

I have found something interesting..........
Prior to Oracle 10g, Oracle's default optimizer mode was called “choose.” In the choose optimizer mode, Oracle will execute the rule-based optimizer if there are no statistics present for the table; it will execute the cost-based optimizer if statistics are present. The danger with using the choose optimizer mode is that problems can occur in cases where one Oracle table in a complex query has statistics and the other tables do not.
This probably explains the fact that I am gathering statistics for 1 table and not the others.
Just checked the explain plan for a particular SQL query and it's using CHOOSE optimizer mode.

Table Statistics failed during Import

Hi All,
I am trying to import an existing schema in Oracle 10g.
I am using the impdp utility.
The export dump consists of the complete schema (metadata and data).

I had then used the parameter EXCLUDE=STATISTICS and then the import was successful.
I would like to the significance of this STATISTICS.
I mean would EXCLUDE=STATISTICS always be ok?
I have exported and imported the scheme as a user and not as sysdba. Does this make any difference?
any suggestion would be highly appreciated.
Thanks,

Best Practice to fetch SQL Server data and Insert into Oracle Tables

Hello,
I want to read sqlserver data everry half an hour and write into oracle tables ( in two different databases). What is the best practice for doing this?
We do not have any database dblinks from oracle to sqlserver and vice versa.
Any help is highly appreciable?
Thanks

Well, that's easy:
use a TimerTask to do the following every half an hour:
- open a connection to sql server
- open two connections to the oracle databases
- for each row you read from the sql server, do the inserts into the oracle databases
- commit
- close all connections

Insert /delete data from SAP Z table to Oracle table and opposite

Hi,
Can u help me write this FM from the SAP side?
So, I have two tables ZTABLE in SAP and Oracle table ORAC.
Let's put three columns in each of them, for example
TEL1
TEL2
ADRESS
NAME
where TEL field is primary from ZTABLE to ORAC...
(in FM there shoud be abap code for writing data in ZTABLE after we press some pushbutton made in sap screen painter..)
for example, when we write new record in ZTABLE
00
112233
Street 4
Name1
this data shoud be inserted in Oracle table ORAC.
when we write new record in Oracle table for example
01
445566
New Street
Name2
this data shoud be inserted in ZTABLE.
Field TEL1 can be only of two values 01 or 02, other combination is not valid...
I must have all data from Oracle table ORAC in ZTABLE and opposite.
It should be the same scenario for DELETE...
And this communication should be online between sap and table in oracle database...
Can u help me from sap side? and give idea how to configure on oracle side??
Thanks a lot,
Nihad

I dont know if we can directly connect to a oracle database ( wait for the answers from others on this )
but in XI we have the JDBC adaptor to insert and retrieve data.
so for the outbound from SAP the flow can be something like this (with XI in landscape):
1) You have a screen to maintain a new entry / delete an entry
2) On save , this record gets saved or deleted from the Ztable in SAP
3)) In the same screen you can call a proxy class-method (generated using SPROXY transaction ) to send the record to XI.
4) XI to format it and insert into the oracle table

Yes it is possible using SQL*LDR, External tables and ORCL Export Utility. Though I didn't try Export Utility to load the external files.
SQLLdr sysntax:
Create a control file.
It looks like this

Fields missing in Oracles tables created by Infospokes

Hi S.A.P Gurus!
My problem is as follows:
We have created Infopokes with Oracle table as destination.
Even though, the transport to other systems is correct, and the infospoke have all the fields, when we execute it, some fields are missing in the destination (oracle table), and they should appear.
Does anyone know what we could do to avoid this problem?
Thanks in advance!
Kind regards.

Hi Raul,
Was just going through your thread ..and found that you were able to transfer the data to the oracle table.
I am aslo working on infospoke where I have to transfer the data from my Infoobject to a table in Oracle.
For that i have created a infospoke and executed it to get the data in the another tabel in sap.
The problem is that I dnt know how to move the data from this table in SAP to oracle table . Did u used any interface for this or any kind of ABAP programming that you have done.
Please suggest how this can be implemented.
I have open up a thread for this InfoSpokes InfoSpokes
Reward Points will be awarded.

Using OleDbDataAdapter Update with InsertCommands and getting blocking locks on Oracle table

The following code snippet shows the use of OleDbDataAdapter with InsertCommands. This code is producing many inserts on the Oracle table and is now suffering from contention... all on the same table. How does the OleDbDataAdapter produce
inserts from a dataset... what characteristics do these inserts inherent in terms of batch behavior... or do they naturally contend for the same resource.
oc.Open();
for (int i = 0; i < xImageId.Count; i++)
// Create the oracle adapter using a SQL which will not return any actual rows just the structure
OleDbDataAdapter da =
   new OleDbDataAdapter("SELECT BUSINESS_UNIT, INVOICE, ASSIGNMENT_ID, END_DT, RI_TIMECARD_ID, IMAGE_ID, FILENAME, BARCODE_LABEL_ID, " +
