To know the size of multiple tables
Hi Oracle Dons:
I need to check the size of multiple tables via a SQL query. The way I would do this for a single table is
select bytes from dba_segments where segment_name='table_name';
But I need to do this for about 4 dozen tables.
Can someone point me along the right corridor?
Thanks.

If you want separate sizes by table and type of segment:
select segment_name,segment_type,sum(bytes)
from dba_segments
where segment_name in ('TABLE1','TABLE2','TABLE3')
group by segment_name,segment_type;If you want the total and don't care about individual sizes or types of segments
select sum(bytes)
from dba_segments
where segment_name in ('TABLE1','TABLE2','TABLE3');

How can I know the size of DB Table
Hi, Guys,
1. How can I know the size of the DB Table in terms of kb
2. If I delete some records from the Table, does the actual size of the Table remains same or will it be reduced.
3. If size remains same after deletion, how to reduce the size ( i.e. occupied space).
thanks
MaheshHi
1. How can I know the size of the DB Table in terms of kb
There is no precise method/tcode/program to know the Table size of a tables.
Just based on the record size of a table(say for example 2kb), and if 200 records are there then, we roughly assume that it occupied 400 kb.
All the tables are stored in Table spaces.
2. If I delete some records from the Table, does the actual size of the Table remains same or will it be reduced.
Time being it remains same. it won't get reduced immediately
during some next DB reorganisation it gets reorganised by reducing it.
3. If size remains same after deletion, how to reduce the size ( i.e. occupied space).
during next DB reorganisation it gets reorganised by reducing it.

How to know the size of a table by using sql command?
i've got a question that i hope to know a table size by using sqlcommand?
what to do?
thanks in advice,Select sum(bytes) bytes, sum(blocks) blocks
from dba_segments
where segment_name = 'YOUR_TABLE';This will give you the space in the database allocated to the table. If you want to know the actual space it takes up then you'll have to analyze the table and interrogate the stats using DBA_TABLES.

How to know the size of a webservice request
Hello...
I'd like to know if you know how do I get the size of a Web request? I mean, I need to know the size of a Web Request 'cause I'll fill a Gauge Object up based on the quantity that I have received from the WebService.
I'm using the KSOAP and KXML API's for consuming that WebServices and I used the Content-lengh Method and it didnt return anything to me... it returned empty. So, do you know how do I fill a Gauge Object based on the size of the WebRequest? Could you tell me some examples plz?
Thanx...

How to know the size of bad sector block after zero out erase?
I found some problems on my USB external harddisk recently. After I backup all the files, I erased the whole volume by choosing "zero out data" option. According to some web articles, "zero out" detects and marks those bad sectors to avoid further read/write action on the damaged area.
My question is that how can I know the size of disk space marked as bad sector? Because I can only see how many space is used or available when I check a disk in disk utility. There are about 600MB used for my 1TB hard drive. I guess there is some storage used by spotlight or other hidden files. But I have no idea for how many MB is occupied by bad sector...Yes you can look at see the original number of spares, the number used, and the number remaining spares.
Disk Warrior for one, writes the SMART data to system.log Other programs can also read and report (not sure which if any write to system.log though) those field values from SMART table entries.
IF the number of spares is declining, time to replace. Trouble is OS X hasn't had a good record of reporting I/O errors, let alone remapping. Some 3rd party utilities will. I've found the vendor (WD, Hitachi etc) have the best utility for their own drives, but those are Windows programs or LinuxCD. Also the best way to zero and map out bad sectors, too. -

I want to know the size of of database
hi, iam using HP-UX with oracle10G so that, i want to know the size of of database in my system, for that i can use the follwing queries is this is correct or not?
1. select sum(bytes) as total_size from dba_data_files;
ANS is:
TOTAL_SIZE
29718740992
2.select sum(bytes) as free_size from dba_free_space;
ANS is:
FREE_SIZE
6940393472
3. select sum(bytes) as used_size from dba_segments;
ANS is:
USED_SIZE
25215827968
i GOT like this iam not getting is this TOTAL size is 28 GB?????????????
4.select * from DBA_FREE_SPACE_COALESCED;
ANS for this ????????????????
please help me anyone......i want to know the size of of database in my systemDefine "size":
- The total size of the dbf files?
- The total data space used?
- The total tablespace size?
For example, this show the size of a single table, in meg:
select
segment_name table_name,
sum(bytes)/(1024*1024) table_size_meg
from
user_extents
where
segment_type='TABLE'
and
segment_name = 'MYTAB' ;

How to know the size in bytes of a directory?
I would like to know if there's a class or a function which allows to know the size of all files in a directory?
You have to create a File object for your directory, then list all files (using the list() method) and create a File object for each item returned. Then ask each File object for it's size and add them up.

How to know the size of the EEPROM after loading any Applet

Thank you in advancekishansaralaya wrote:
Thanks for your suggestion.
But when I try to use
short memRemaining = JCSystem.getAvailableMemory(JCSystem.MEMORY_TYPE_PERSISTENT);
it always shows 32767. Even after loading some applet.
And I am using 72K Java card then how it can show only 32Kbyte as the remaining memory value.This is because a short isn't big enough to display a number above 32767. One way around this is to use a byte[] to fill up some of the space with your temporary applet.
byte[] memoryFiller = new byte[32767];
short memRemaining = JCSystem.getAvailableMemory(JCSystem.MEMORY_TYPE_PERSISTENT);The value of memRemaining + 32767 is the amount of persistent memory left on the card. If memRemaining is still 32767, you can add another byte[] starting with small values and increase the size until you get a meaning ful result (less than 32K). -

How can I know the size of a JViewport laid out in BorderLayout.CENTER?
I have a JPanel inside a JScrollPane. The scroll pane is laid out inside of BorderLayout.CENTER. I need to know the size of the JViewport to do stuff like centering and zooming.
Where can I find the size? All these methods return 0 values for X and Y:
myScrollPane.getViewport().getSize()
myScrollPane().getSize()
myScrollPane.getHorizontalScrollbar().getValue()
Yes, even the scrollbars won't give me any values! It's all because of the BorderLayout!
Any ideas? Thanks.Sounds like you are accessing the sizes before the views are realized (that is before a call to frame.pack()/show()) They are available only after the layoutManager had a go on it. What is available earlier are preferred/min/max, though.
Greetings
