Truncate table that has 2 billion rows

Hi,
Our DB is 11g and approximately any idea howmuch time it takes and do we need to rebuild indexes after truncate?

Before you do that - do you plan to reload the table with a similar amount of data?
If so then you might want to use the REUSE STORAGE clause so that Oracle doesn't have to deallocate and then immediately reallocate the storage.
See the SQL Language doc
http://docs.oracle.com/cd/B28359_01/server.111/b28286/statements_10007.htm
>
REUSE STORAGE Specify REUSE STORAGE to retain the space from the deleted rows allocated to the table. Storage values are not reset to the values when the table or cluster was created. This space can subsequently be used only by new data in the table or cluster resulting from insert or update operations. This clause leaves storage parameters at their current settings.
>
If you plan to do a large reload you should consider dropping or disabling the indexes and then adding/rebuilding them after the data load.

How to update a table that has hundred thousand rows?

Hi all !
I detect that I did wrong with column SHAPE (in GRAG table ) ,namely at Gtype : 3003
(MDSYS.SDO_GEOMETRY(3003,50632625,'null',MDSYS.SDO_ELEM_INFO_ARRAY(1,5,1,1,2,1),MDSYS.SDO_ORDINATE_ARRAY(276.2339,-179.7433,0,276.2498,-179.7361, 0 ))
And I need to update value Gtype :3003 to 3002 .
My problem is I don't know how to implement it because GRAG table has 30000 rows . I cannot update every row manually .
Do you have any advice ?

AFAIK oracle11g cannot simply update SDO_GEOMETRY.
so you have to create new SDO_GEOMETRY with all but one old values.
try to modify this (I wrote it once to circumvent the cannot modify SDO_GEOMETRY problem):
-- clones a geometry but with different values
-- we can "alter" the SRID
-- note: oracle 11g cannot modify geometries
function alter_geometry(p_geo sdo_geometry, p_srid number default null)
return sdo_geometry is
v_result sdo_geometry;
v_srid number;
begin
if p_srid is null then
v_srid := p_geo.SDO_SRID;
else
v_srid := p_srid;
end if;
v_result := sdo_geometry(p_geo.SDO_GTYPE,
v_srid,
p_geo.SDO_POINT,
p_geo.SDO_ELEM_INFO,
p_geo.SDO_ORDINATES);
return v_result;
end alter_geometry;
--then do an update like
--test before with an create table as select
update crack c set c.shape = alter_geometry(shape, ...)

How to write a cursor to check every row of a table which has millions of rows

Hello every one.
I need help. please... Below is the script (sample data), You can run directly on sql server management studio.
Here we need to update PPTA_Status column in Donation table. There WILL BE 3 statuses, A1, A2 and Q.
Here we need to update PPTA_status of January month donations only. We need to write a cursor. Here as this is a sample data we have only some donations (rows), but in the real table we have millions of rows. Need to check every row.
If i run the cursor for January, cursor should take every row, row by row all the rows of January.
we have donations in don_sample table, i need to check the test_results in the result_sample table for that donations and needs to update PPTA_status COLUMN.
We need to check all the donations of January month one by one. For every donation, we need to check for the 2 previous donations. For the previous donations, we need to in the following way. check
If we want to find previous donations of a donation, first look for the donor of that donation, then we can find previous donations of that donor. Like this we need to check for 2 previous donations.
If there are 2 previous donations and if they have test results, we need to update PPTA_STATUS column of this donatioh as 'Q'.
If 2 previous donation_numbers has test_code column in result_sample table as (9,10,11) values, then it means those donations has result.
BWX72 donor in the sample data I gave is example of above scenario
For the donation we are checking, if it has only 1 previous donation and it has a result in result_sample table, then set this donation Status as A2, after checking the result of this donation also.
ZBW24 donor in the sample data I gave is example of above scenario
For the donation we are checking, if it has only 1 previous donation and it DO NOT have a result in result_sample table, then set this donation Status as A1. after checking the result of this donation also.
PGH56 donor in the sample data I gave is example of above scenario
like this we need to check all the donations in don_sample table, it has millions of rows per every month.
we need to join don_sample and result_sample by donation_number. And we need to check for test_code column for result.

You didn't mention the version of SQL Server. It's important, because SQL Server 2012 makes the job much easier (and will also run much faster, by dodging a self join). (As Kalman said, the OVER clause contributes to this answer).
Both approaches below avoid needing the cursor at all. (There was part of your explanation I didn't understand fully, but I think these suggestions work regardless)
Here's a SQL 2012 answer, using LAG() to lookup the previous 1 and 2 donation codes by Donor: (EDIT: I overlooked a couple things in this post: please refer to my follow-up post for the final/fixed answer. I'm leaving this post with my overlooked
items, for posterity).
With Results_Interim as
Select *
, count('x') over(partition by donor_number) as Ct_Donations
, Lag(test_code, 1) over(partition by donor_number order by donation_date ) as PrevDon1
, Lag(test_code, 2) over(partition by donor_number order by donation_date ) as PrevDon2
from RESULT_SAMPLE
Select *
, case when PrevDon1 in (9, 10, 11) and PrevDon2 in (9, 10, 11) then 'Q'
when PrevDon1 in (9, 10, 11) then 'A2'
when PrevDon1 is not null then 'A1'
End as NEWSTATUS
from Results_Interim
Where Test_result_Date >= '2014-01' and Test_result_Date < '2014-02'
Order by Donor_Number, donation_date
And a SQL 2005 or greater version, not using SQL 2012 new features
With Results_Temp as
Select *
, count('x') over(partition by donor_number) as Ct_Donations
, Row_Number() over(partition by donor_number order by donation_date ) as RN_Donor
from RESULT_SAMPLE
, Results_Interim as
Select R1.*, P1.test_code as PrevDon1, P2.Test_Code as PrevDon2
From Results_Temp R1
left join Results_Temp P1 on P1.Donor_Number = R1.Donor_Number and P1.Rn_Donor = R1.RN_Donor - 1
left join Results_Temp P2 on P2.Donor_Number = R1.Donor_Number and P2.Rn_Donor = R1.RN_Donor - 2
Select *
, case when PrevDon1 in (9, 10, 11) and PrevDon2 in (9, 10, 11) then 'Q'
when PrevDon1 in (9, 10, 11) then 'A2'
when PrevDon1 is not null then 'A1'
End as NEWSTATUS
from Results_Interim
Where Test_result_Date >= '2014-01' and Test_result_Date < '2014-02'
Order by Donor_Number, donation_date

Table that has the hier text names and the corresponding hier ID

Hi,
Would anyone happen to know the table that has the hier name text as it appears from the infoObject level and the corresponding Internal hierarchy ID (unique ID) for data element RSHIEID. I would want ot be bale to match the text name o f the hier to the hier ID.
Thanks
Will

Trying to make it simpler taking the 0material hierarchy note that the 0material has been loaded with 3 different hierarchies:
fields in the H table:
HIEID - 434FLR9O6DX0XXJS3CLIYZODD (Refers to the particular hierarchy as mentioned I have 3 hierarchies loaded to 0Material)
OBJVERS - Active and so on
NODEID - 4 digit internal number of the hierarchy
These are the Keys that identifies the hierarchy uniquely in my case the 1st hierarchy.
Now if you want to find the nodes then based on the example above I will take the hierarchy id ie 434FLR9O6DX0XXJS3CLIYZODD for the field HIEID that would give me all the nodes of this hierarchy
Note: the HIEID for a particular hierarchy can be found from the HEADER info
Thanks,
Raj

Import to new table that has additional fields

Hi Everyone,
I am trying to migrate a table to a new table that has the field sequence changed and also has a new field added. My main question is if it is possible to have datapump add values to the new field in the target table.
For example:
original table has fields a, b, d, c
new table has fields b, c, d, a, e
I want to load the new table and also include adding values for field e. In this case, field e is a year field, so it should be loaded with '2012'
Does datapump have the ability to do this? Is reorganizing the fields going to cause me any problems?
We are on oracle version 11.2.0.3

remap data simply replaces data is a column. You can't populate additional columns when performing a data pump import. The internal code would have no idea what to put in that column and there is no user interface to tell Data Pump what to put in that column. REMAP_DATA simply replaces data in the specified column.
remap_data:schema.table:column:function
This function returns a single value and the column is populated with that value.

Problem with a table that user can add rows to

I have a form that has a table with header. I have included a button that users can click to add rows to the table. I have gotten a few forms back where for some reason the header row has been repeated. I haven't been able to recreate this on my end and my users can't identify exactly what they are doing to get those extra header rows. I have included screen shots of the problem pages here. I would love to upload the form since I believe my issue is with the script, but can't seem to do that. I'm signed in to adobe.com, but when I go to new and documents and upload a file, everything is greyed out. Am I missing something that would enable me to upload the document? Specific instructions would be appreciated.
Thanks!

Hi,
For both/all tables the HeaderRow should not be set to repeat (see the Object > Binding palette). Go to the HeaderRow in the hierarchy (for each table) and untick the "Repeat Row.."
That should solve the problem.

Is there a way to create tables that can't update rows

Hi
I have an application where security is very importante. I have tables that con only be inserted and queried, not updated or deleted. Is there a way I can tell Oracle to prohibit update and delete on that table.
Regards,
Néstor Boscán

> Is there a way I can tell Oracle to prohibit update and delete on that table.
Yes. Quite easy in fact. It is called FGAC - Fine Grained Access Control.
You create a FGAC function for those tables. These simply returns 1=2 to be added to an UPDATE or DELETE statement's predicate.
Example:
SQL> -- am able to delete from emp
SQL> delete from emp;
17 rows deleted.
SQL> rollback;
Rollback complete.
SQL>
SQL> -- create policy FGAC function
SQL> create or replace function vpdbPolicy( schema varchar2, object varchar2 ) return varchar2 is
2 begin
3 return( '1=2' );
4 end;
5 /
Function created.
SQL>
SQL> -- create FGAC policy
SQL> begin
2 DBMS_RLS.add_policy(
3 object_schema => USER,
4 function_schema => USER,
5 object_name => 'emp',
6 policy_name => 'PROTECT_EMP',
7 policy_function => 'vpdbPolicy',
8 update_check => FALSE,
9 statement_types => 'UPDATE DELETE'
10 );
11 end;
12 /
PL/SQL procedure successfully completed.
SQL>
SQL> -- no longer able to delete from emp
SQL> delete from emp;
0 rows deleted.
SQL> rollback;
Rollback complete.
SQL>

Select Query failing on a table that has per sec heavy insertions.

Hi
Problem statement
1- We are using 11g as an database.
2- We have a table that is partitioned on the date as range partition.
3- The insertion of data is very high.i.e. several hundreds records per sec. in the current partitioned.
4- The data is continuously going in the current partitioned as and when buffer is full or per sec timer expires.
5-- We have to make also select query on the same table and on the current partitioned say for the latest 500 records.
6- Effecient indexes are also created on the table.
Solutions Tried.
1- After analyzing by tkprof it is observed that select and execute is working fine but fetch is taking too much time to show the out put. Say it takes 1 hour.
2- Using the 11g sql advisior and SPM several baseline is created but the success rate of them is observed also too low.
please suggest any solution to this issue
1- i.e. Redisgn of table.
2- Any better way to quey to fix the fetch issue.
3- Any oracle seetings or parameter changes to fix the fetch issue.
Thanks in advance.
Regards
Vishal Sharma

I am uploading the latest stats please let me know how can improve as this is taking 25 minutes

Rename a column on a table that has fulltext index on the renaming column

I have to rename a column on a table, which has an fulltext assigned to the specified column.
Will this make the fulltext crash or in any other way have a effect to the fulltext search ???
And/Or do i need to alter the fulltext also ?
PS: TSQL Example would be nice ;)
Best regards
Paw

Best course of action is to drop the index, rename the column, create the index.

SQL Loader - Loading Text File into Oracle Table that has carriage returns

Hi All,
I have a text file that I need to load into a table in Oracle using SQL Loader. I'm used to loading csv or comma delimited files into Oracle so I'm not sure what the syntax is when it comes to loading a text file that essentially has one value per row and each row is separated by a carriage return. So when you open the text file, the records look like this:
999999999 <CRLF>
888888889 <CRLF>
456777777 <CRLF>
456555535 <CRLF>
345688888 <CRLF>
So each row is separated by a hard return and I need to tell sql loader that the hard return or next row is the next value to insert into the table. Below is an example of a control file I tend to use as a template for loading csv files but I need to modify it to accomodate this new structure.
OPTIONS (DIRECT=TRUE,ROWS=100000)
UNRECOVERABLE
LOAD DATA
INFILE 'C:\input.txt'
BADFILE 'C:\input.bad'
APPEND
INTO TABLE TEST_TABLE
FIELDS TERMINATED BY ","
TRAILING NULLCOLS
COLUMN_1
How to I modify the control file above to use hard returns as the field/row delimiter for my text file?
Thanks

Hi there,
Obviously my intention wasn't to post the same message 4 times....I pressed the "Submit Message" button but the submission hung and I pressed it a few times and finally it worked but it created several versions of my post. You need to allow users the ability to delete there own postings...I was looking for this option but didn't have it.
Sorry

How to update a table that has Million Records

Hi,
Lets consider the basic EMP table and lets assume that it has around 20 Million Records . we need to have an update statement.Normal UPdate statement may hang the system or it may take a lot of time.
The basic or Normal update statement goes like this and hope it may not work.
update emp set hiredate = sysdate where comm is null and hiredate is null;Basic statement may not work. sugestions Needed.
Regards,
Vinesh

I heard Bulk collect will resolve these type of issues and i am really poor at Bulk Collect concepts.Exactly what type of issue are you concerned with? The business requirements here are pretty important-- what problem is the UPDATE causing, specifically, that you are trying to work around.
so looking for a solution to the problem using Bulk Collect .Without knowing the problem, it's very tough to suggest a solution. If you process data in batches using BULK COLLECT, your UPDATE statement will take longer to run and will consume more resources on the database. If the problem you are trying to solve is that your UPDATE is not fast enough, this is a poor approach.
On the other hand, if you process data in batches, and do interim commits, you can probably hold locks on individual rows for a shorter amount of time. That would only be a concern, though, if you have some other process that is trying to update the same rows that you are updating at the same time that you're updating them, which is pretty rare. And breaking your update into multiple transactions introduces a whole bunch of complexity. You now have to write a bunch of code to ensure that your process is restartable should the update fail mid-way through leaving some number of updates committed and some number rolled back. You have to have a very detailed understanding of the data and data consistency to ensure that breaking up the transaction isn't going to negatively impact any process, report, etc. To do it correctly is a pile of work and then it's something that is constantly at risk of creating problems in the future when requirements change.
In the vast majority of cases, you're better off issuing a simple SQL statement during a time when the system isn't particularly busy.

Selection color not working with table that has DefaultTableModel

hi folks,
I noticed if a table has a AbstractTableModel, when you select a row, by default the highlight color is light blue. However, if a table has a DefaultTableModel, even if you invoke table.setSelectionBackgroun(color) and table.setSelectionForefround(color), the highlight color stays invisible. is this a bug? what's the cause of this problem?
thanks!!

Read this section from the Swing tutorial on [url http://java.sun.com/docs/books/tutorial/uiswing/components/table.html#renderer]Using Table Renderers. Here is a simple example to get you started
    class SimpleRenderer extends DefaultTableCellRenderer
        public Component getTableCellRendererComponent(
            JTable table, Object value, boolean isSelected, boolean hasFocus, int row, int column)
            super.getTableCellRendererComponent(table, value, isSelected, hasFocus, row, column);
            if (hasFocus)
                setBackground( Color.cyan );
            else if (isSelected)
                setBackground( table.getSelectionBackground() );
            else
                setBackground( table.getBackground() );
            return this;
    }

How to update a table that has around 1 Million Records

Hi,
Lets take the basic emp table for our Referenece and lets assume that it contains around 60000 Records and all the deptno in that table are Initially 10. Please provide an update statement which would update deptno column of EMP table((based on) order by EMPNO) in for every 120 records incrementing by 1.(DeptNo to be incremented by 1,like 10 ,11 , 12 etc).
First 120 Records deptno should be 10,
Next 120 Records deptno should be 11, and so on.
For Last 120 records deptno should be updated with 500.
Please advise.
Regards,

Ok, I've done it on a smaller set, incrementing every 5 records...

Unable to create new entry in table that has no primary key

Hi
I have a table which is required to have no primary key (except mandt). After i generate table maintanance, when I go to create new entries, the table control to enter the new values does not appear. When I click on edit->new entries, it goes back to the fields tab of the table. Same when i check through SM30.
If i maintain atleast one primary key, I am able to get the table control in new entries screen. However the requirement permits no primary keys except mandt. How can this be resolved?
Thanks
NM

Hi,
THE PROBLEM WITH UR TABLE IS
YOU HAD DECLARED MANDT AS THE PRIMARY KEY AND THERE IS NO OTHER KEY IN UR TABLE
iT'S NOT ALLOWING YOU TO ADD NEW ENTRIES BECAUSE MANDT IS THE ONLY PRIMARY KEY IN YOUR TABLE AND IT WILL HAVE A DEFAULT VALUE BASED ON THE CLIENT. SO IT'S NOT SHOWING YOU THE CREATE NEW ENTRIES OPTION.
SO TRY TO PUT ONE MORE FIELD AS THE PRIMARY KEY SO THAT YOUR PROBLEM WILL SOLVE VERY EASILY ALSO MAKE SURE THAT TABLE IS ACTIVATED.
REVERT IF U NEED SOME MORE HELP
Thanks &Regards.

can anyone tell me is there any other way to acheive the same.
i thought of doing using insert query,but i am not sure about the syntax to be used.
could anyone help me ?
thanks in advance...
