How to disable all Constraints for a Table
Hi There,
So I have a table that I need to delete a significant amount of records from. Using some advice I found it better to select the records that I wanted to keep into a temporary table and then truncate the original table. After that I insert the contents of the temp table into the original table.
So now I am thinking I could speed this up even more if I disable all the constraints on the original table.
Is there an easy way to do this or do I need to disable each constraint individually?
thanks
John

How to disable all constraints on a table
Hi ,
I want to disable all constraints on a table
select 'ALTER TABLE '||substr(c.table_name,1,35)||
' DISABLE CONSTRAINT '||constraint_name||' ;'
from user_constraints c
where c.table_name = MY_table;
thanks in advanceWhat is wrong with query you have?
Why do you have substr around the table name?
If you want to execute the output as well, do this,
SET SERVEROUT ON
BEGIN
FOR i IN (SELECT 'ALTER TABLE ' || c.table_name || ' DISABLE CONSTRAINT ' || constraint_name AS l_sql, table_name, constraint_name
FROM user_constraints c
WHERE c.table_name = my_table_name)
LOOP
EXECUTE IMMEDIATE i.l_sql;
DBMS_OUTPUT.PUT_LINE ('Disabled constraint ' || i.constraint_name || ' on table ' || i.table_name);
END LOOP;
END;

How to drop all constraints on a table?
Oracle 11gR2
I tried this but no luck!
ALTER TABLE testDB.dbo.testTable1
DROP ALL CONSTRAINT
GOOracle 11gR2
I tried this but no luck!
ALTER TABLE testDB.dbo.testTable1
DROP ALL CONSTRAINT
GO
You never will have any 'luck' trying to execute SQL SERVER statements on an Oracle database.
There is no Oracle command to drop all constraints from a table.
1. create a new table using CTAS - CREATE newtable AS SELECT * FROM oldtable
2. drop the orginal table - DROP oldtable
3. rename the new table to the old name - RENAME newtable to oldtable
Constraints will be gone. -
How to disabled all constraints when importing data (urgent)
Hi,
I am running import on my database. It’s dump file size 40GB & I forget to set import parameter constraint=N. due to that import is very slow.
Could any body help me out.
Thanks,
ATHi,
>>due to that import is very slow
I'm not sure whether this is the "source" of low performance, because just in the end of the process that integrity constraints are enabled.
1) New tables are created. (Type definitions, Table definitions)
2) Data is imported. (Table data)
3) Indexes are built. (Table indexes)
4) Triggers are imported. (integrity constraints, views, procedures, and triggers)
5) Integrity constraints are enabled on the new tables.
6) Any bitmap, functional, and/or domain indexes are built.

How To Display All Comments for a Planning Package
Hi,
I have the How-to guide mentioned in the subject and have now moved onto BI7. Is the guide still applicable in BI7 and how would I go about implementing the above How-to in IP instead of BPS?
Thanks,
AleThanks Marc.
I will use BW-BPS for the time being as I've seen screenshots of the solution in the how-to. Still need to answer the question here:

Urgent: How to list all alias for a server throw DNS query?
Hi
Is there anyone know how to list all alias for a server by asking the network DNS. Is that possible?
It doesn't work with InetAddress it return a single result.
Best regardInetAddress will not get you the aliases, but you can certainly find all the different IP addresses for a specific host name using the getAllByName() method.
You won't be able to get the aliases since those IP addresses (assuming there are more than 1) will all be cached as mapping to the name you passed to the getAllByName() method and you can't clear the map cache until the JVM exits.
So your best hope is to get a list of IP's and either exit your app and restart with a new mode, or save them to a file for another app to read. -
How to set DDL lock for a table
OCI,how to set DDL lock for a table?
Oracle acquires a dictionary lock automatically on behalf of any DDL transaction requiring it. Users cannot explicitly request DDL locks. Only individual schema objects that are modified or referenced are locked during DDL operations. The whole data dictionary is never locked
DDL locks fall into three categories: exclusive DDL locks, share DDL locks, and breakable parse locks.

NOT WORKING -How To Display All Comments for a Planning Package
Hi All,
I am using How to Document "How To Display All Comments for a Planning Package" to display comments for list of "cost center" against different "fiscal/year" for Key Figure "Budget Amount".
Below is how the Layout looks like where comments are posted against Cost Center- year combination.
Cost Center 2007 2008 2009 2010 2011
3 2.00 2.00 2.00 2.00 2.00
4 2.00 2.00 2.00 2.00 2.00
6 2.00 2.00 2.00 2.00 2.00
7 2.00 2.00 2.00 2.00 2.00
This case is very similar to the example given in how to document but after following all the steps correctly in the document and also followings various forum links such as below , I am not able to display the comments for list of Cost Centers.
"How to...BSP display comments"...problem with row comment
Below are the issues being faced:
1) When i save the comments , the icon for comments (indicating that some comments have been entered) is not shown against selection of Cost Center-Year although the comment is saved.Comment are also visible in BPS0.
2) On execution "Web interface could not be loaded" - is the message that is shown in the area where BPS application should show all the comments.
Highly Appreciate any help with issues mentioned above.
Kind Regards,
Robin JohriHello Robin,
1) please check if you set the row/cell selection property correctly for the layout component in the web interface.
2) the error does not make sense since the comments are displayed in an iframe using a BSP application, not a web interface. Check the URL in the HTML text component.
Regards,
Marc

How to disable certain columns of a Table?
hi all,
I wish to fill a pattern of 8 digital signals (only 1's & 0's) in a Table.
Is there any way to restrict the user from typing char or num other than a 1 or a 0?
Since the table is a string, I'm having confusion how to do this.
Secondly, the table would have by default 12 columns visible on the Front Panel, excluding both the headers.
But the No. of Columns is based on a parameter called Duration that ranges between 4 & 256.
What I want the user to do is to key in 1's & 0's for the Duration chosen.
Since it'll be tedious to key in for large values of Duration, I've given the option of Set Row(s) & Reset Row(s),
that will fill with either 1 or 0 respectively for the chosen Row Value.
Is there any way to disable the remaining columns of the Table, ie, those unfilled columns,
when the user scrolls horizontally? I don't know how to achieve this.
I went thro' the Properties of the Table, I don't understand some of their functionalities,
like SelStart, SelSize etc.
I wonder why a Property like Disable Array Elements for Arrays is not provided for a Table
to Disable the columns we want to do so, or is it my gross ignorance, I don't know.
Experts pls clarify me & help me out.
Regards,
Partha.

Slightly more elegant, but also more potential for bugs (e.g. the users can tab into the column).

You can lower your overhead by using these "professional" looking indicators and controls. They are limited in functions and properties, thereby causing a smaller VI in file size.
Nice. I didn't think about that. Looks like a VI with a single system boolean takes ~20% less space than one with a standard boolean.
P.S. In general, I would say there are considerably better arguments for using system controls than memory issues.
Try to take over the world!

How to disable automatic statistics collections on tables
Hi
I am using Oracle 10g and we have few tables which are frequently truncated and news rows added to it. Oracle automatically analyzes the table by some means which collects statistics of the table but at the wrong time(when the table is empty). This makes my query to do a full table scan rather using indexes since the statistics was collected when the table was empty.Could any one please let me know how to disable the automatic statistics collection feature of Oracle?
Cheers

the automatic statistics collection feature of
Oracle?
First of all I think it's important that you understand why Oracle collects statistics on these tables: Because it considers the statistics of the object to be missing or stale. So if you just disable the statistics gathering on these tables then you won't have statistics at all or outdated statistics.
So as said by the previous posts you should gather the statistics manually yourself anyway. If you do so right after loading the data into the truncated table, you don't need to disable the automatic statistics gathering as it only processes objects that are stale or don't have statistics at all.
If you still think that you need to disable it there are several ways to accomplish it:
As already mentioned, for particular objects you can lock the statistics using DBMS_STATS.LOCK_TABLE_STATS, or for a complete schema using DBMS_STATS.LOCK_SCHEMA_STATS. Then these statistics won't be touched by the automatic gathering job. You still can gather statistics using the FORCE=>true option of the GATHER__STATS procedures.
If you want to change the automatic gathering job that it only gathers statistics on objects owned by Oracle (data dictionary, AWR etc.), then you can do so by calling DBMS_STATS.SET_PARAM('AUTOSTATS_TARGET', 'ORACLE'). This is the recommended method.
If you disable the schedule job as mentioned in the documentation by calling DBMS_SCHEDULER.DISABLE('GATHER_STATS_JOB') then no statistics at all will be gathered automatically, causing your data dictionary statistics to be become stale over time, which could lead to suboptimal performance of queries on the data dictionary.
All this applies to Oracle 10.2, some of the features mentioned might not be available in Oracle 10.1 (as you haven't mentioned your version of 10g).

Randolf
