How to find the more than 20GB tables

Hi Friends,
I would like to know the tables which has more than 20GB in oracle.
If any one knows, Plz let me know.
Thanks in Advance.

Depending slightly on your definition of GB (i.e. the disk vendor's 1 billion bytes or normal people's 1024^3 bytes)
SELECT owner, segment_name, SUM(bytes)/1024/1024/1024 GB
FROM dba_segments
WHERE segment_type = 'TABLE'
GROUP BY owner, segment_name
HAVING SUM(bytes) > 20 * 1024 * 1024 * 1024Remove the segment_type = 'TABLE' if you want all objects that are greater than 20 GB in size.

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.

How to pack the More than one sales order delivery qty in one packing

Hi Folks,
How to pack the more than one sales order quantity combinely during packing?
Thansk in advance and points wil be rewarded for the reply.
Best Regards
Srinivas

Packing is done during Delivery.
In Sales order also Packing function is available but as a Packing proposal.
So actual packing is done in Delivery.
When you process several sales orders together, the sales order items having same Ship-to-party, Shipping point, Route, Delivery due date & Incoterm are combined into one Delivery in the standard system.
In the delivery overview screen,do the picking by subsequent function rom the menu bar, you will get a button "PACK", click on this system will take you to the packing screen.
In the packing screen, give the packaging mterial number, select the materials to be packed, select the packaging material also and the click on the "PACK" button.

How to find the deleted data in tables

MBEWH is actually the history table of MBEW. It will record all the changes. As I have told you earlier if you have deleted the record dirctly from the table then it will not come even in the table MBEWH
That means no changes have been made.

You use Solution Manager to do the comparison for you. There are some nice features that will highlight all your customised coding. Have a look at the SolMan resources on the Support Portal e.g. using SolMan for upgrade comparisons.

How to bring the more than one rows from the table into the script

Hi
I have to bring more than one rows from the table into the Main windows of the script. so plz help me out.
Thanks in Advance
Ananya

Hi Ananya,
   Bring more than one row into main window of script.
   For this you need to do some changes for data which you pass to main window.At a time you need to pass more than one row,so for this you need to define one structure.See below code.
Types:begin of ty_rows,
     include structure (your row_structure),
     include structure (your row_sturcture),
Types:end of ty_rows.
for example....
If i need to pass 2 vendor details at a time to main window then the structure should be like this.
Types:begin of ty_rows,
       vendor1 like lfa1-lifnr,
       vendor1_name like lfa1-name1,
       vendor2 like lfa1-lifnr,
       vendor2_name like lfa1-name1,
      end of ty_rows.
Data:i_main type standard table of ty_rows,
     wa_main type ty_rows.
Based on condition you can pass more than one rows of your actual internal table data to i_main internal table.
Then you can pass i_main internal table to your main window.
    I think this will help you.
Cheers,
Bujji

How to find the dependency of a table

Hi All,
how to find all packages or procedure which are using specific table . is there any table where we can go and search .
i mean i have table called let say table_A and i want to find in which procedure or package this table will be using .

Tables dont depend on packages/procedures.
However packages/procedures may use tables.
That said, if youre using TOAD, just press F4 on the table name and click on the used by tab.
