Optimise query on the table which contain 1000 column

Hi ,
I have query on the table which contain 1000 columns
when i am executing query on same table .It is taking time .
Select * from abc
where col1 between start_date and end_date ;
abc table contain 1000 columns.
please tell me how to optimise query

Yeah, that was my thought as well ... 1000 columns? wtf?
I can't think of many reasons for why you'd need to do a select * on it, and the scenarios that would require that are better addressed at the DBA level, perhaps using db replication and the data pump, etc. So to start with try selecting just the data you would need.
One thing you can do right off the bat is to partition that table by date, and also to analyze and run statistics on it (this was a nightly operation at my last job).
You can also create a materialzed view that refreshes overnight, just on the slice of the data you need. Use a forced fast refresh to make it current before you use it.

Please help me to know the tables which contain details of APD and Open hub destination

Hi experts,
I need to know the list of APDs that have been created in our system. So can you please let me know the table name (if there is any) which contains the name of the APD and as well as the status (active / inactive) of the APD.
Thanks ,
Shalini

Hi Shalini,
Go to RSANWB T-code and select any analysis process. Then press the "monitor" button. On the monitor screen, you can see the selection criteria in a table on the right. Now double-click on the table and a popup will come up where you can set the selection criteria. in particular, you can set the time frame and the analysis process selection.
Hope it 'll help you..........

How can I import data using .dmp into the table which has more columns then in import

I am building the history for warehouse purpose on Oracle 8i database and want to use the old import (.dmp) files (from oracle 7.3.4) to import data but the underlying table is having few more columns which are not in my old DMP file .. how can I import the data into these altered tables while using the same *.imp files .
Any solutions ?

That is the most obvious solution .. but think of the case when my operational database which is the source of my data is undergoing changes every quarter i.e after every 3 months there are some changes on underlying table structures which means structures of my import files will always be different after evry quarter .. you can imagine the number of temporary import structures I need to create .. can't there be a solution wherein I can write an SQL over the import file to read the data in required format ..

Dynamic SQL statement to select the tables which are updated today...

Hi Guys,
I need to find the names of all the tables which contain rows that are inserted/updated in a given time stamp...
Below statement gives me the list of all the tables in the database...
select t.table_name from all_tables t;All these tables in the database have a column called rowversion which gives the updated/inserted date of a record. I need to write a select statement (probably dynamic) which will give me the table names which contain the rowversion value 24-01-2013....
Any help is very much appreciated...

Export dump only 1000 tables from the schema which contains 3000 tables.

Hi,
I have an requirement to export the dump only with particular 1000 tables from the schema which contains 3000 tables.

Kindly guide me on this to proceed further to take the dump of only particular 1000 tables.

if you're using 10g, you could use datapump export/import to achieve this. Not a straight way.

For the schema that you've logged in to, you could do something like this:
test@XE>
test@XE> @test
test@XE> --
test@XE> set serveroutput on size 1000000
test@XE>
test@XE> declare
2    n_count number;

4    for rec in (select object_name from user_objects
5                where object_type = 'TABLE')
6    loop
7      execute immediate 'select count(*) from '||rec.object_name
8      into n_count;
9      if (n_count = 0) then
10        dbms_output.put_line(rec.object_name);

Find the schema which contains all these tables

In my DB, only SCOTT has all the three tables EMP,DEPT, BONUS. There are schemas which have either one or two of these tables but only SCOTT has all these 3 tables.
To find the schema which contains all these *3* tables. I tried the below mentioned queries which gave the wrong answers.
1.
select TABLE_NAME, owner from dba_Tables where table_name IN ('EMP','DEPT', 'BONUS')-- will return any schema which has any of these tables. So, wrong result
2.
select TABLE_NAME, owner from dba_Tables where table_name = 'EMP' AND TABLE_NAME='DEPT' AND TABLE_NAME= 'BONUS'-- Wrong result because it is mutually contradictory. As AP has mentioned below, A table_name cannot be equal to all the three tables .

Thanks everyone. So, this means that this seemingly simple query cannot be written with just a plain AND , OR . Right?You're right. Every query needs SELECT and FROM, for example.
What's wrong with Solomon's simple solution?
Whatever you don't like about it, I'm sure there's another approach that doesn't have the same problem, even if it is slower and more complicated.
As AP pointed out, no one row has all the information you need to decide if that row will be part of the result set or not.
You need something that can make a decision based on the data in multiple rows.
GROUP BY, like Solomon suggested, is the easiest and most efficient way I know of.
Anything that GROUP BY does can probably be done by analytic functions. In this case, it will be more complicated and slower, but you can get the same results.
A self-join, as user13524665 demonstrated, is another way.
You could also get the results you want using EXISTS-, IN-, or scalar sub-queries, all of which would be even more complicated, and scale just as poorly, as a self-join.
CONNECT BY, recursive sub-queries, MODEL, and XML functions can also look at several rows at the same time. I don't believe you want to read and test soltuions for all of these any more than I want to write all of them. Solomon gave a good solution for your original problem. If you want to add some extra restrictions to your problem (such as "I can't use ... or ...") explain clearly what those restrictions are, and why you need them.

Table which contains name of the report generated from table

Hello everyone,
Is there any table which stores the report names that are created from table.
For example if my table name is 'ABC' a new report will be created for table at run time '/1BCDWB/DB/ABC'.
I also need to have table names, which stored the values when a layout is changed
For example if I have ten fields in my table, first time ill choose 5 fields, second time ill change the layout and choose 10 fields and ill save the layout.
If any Function modules are there please let me know
Please let me know, if anyone has details.
Thanks,
Gayatri.

How can i join more than 20 tables which contains more than 5 lacks records

how can i join more than 20 tables which contains more than 5 lacks records

If you're trying to join 20 tables I would check:
- Are all the joins necessary. It's easy sometimes to just join to another table because you're unsure as to whether it's required.
- What sort of application is it? 20 joins seems a lot to me. Are you trying to achieve too much with one query? Is it possible to break the problem down?
- If it is necessary to join so many tables then force the use of hash joins in the query, especially if you're processing a lot of data and want the best throughput. If you want a quicker response, this will not be a appropriate.
