Calculate size of row

HI all,
I need to calculate size of row in bytes .
Is there any way to do this ?
I have heard about vsize function..
TIA
Sumukh

Or since vsize requires data to exist run an analyze or dbms_stats and then see the dba_tables.avg_row_len column value.
This is the average row length for the existing data including the row overhead.

Size of Rows

Hi,
How can we calculate the size of rows or row. I mean suppose i have a table with 50 million rows (lets assume the size is 20 GB). Now out of this how can i calculate the size of say 22million rows. The 22 million rows may be selected by firing a query that satisfy some criteria.
Kindly help me.
Thanks in advance.

Assuming you're selecting a reasonable and representative fraction of the rows, I'd suspect that you'd just want something like
data volume = (# rows you're selecting / # rows in table) * size of table
If you use the CBO and your statistics are reasonably accurate, you could also
SELECT <<num rows you're selecting>> * avg_row_len
FROM user_tables
WHERE table_name = <<table name>>Justin

Maximum size of row-wise variable

Good day for all!
Anybody know, what is the maximum size (in rows) of row-wise initialized variable, or, generally, what affects on the it size?

Hi
Use vsize fuction. like if for table containing two fields t1, t2 then
select vsize(t1)+vsize(t2) from emp where
t1 = x;
U will get size in bytes.

Calculate profit at row level in Discoverer Plus

HI,
I need to calculate profit at row level in Discoverer Plus as follows.
There are columns
1)     Account Name- Contains Expense and revenue account names
2)     Account type- Contains Identifier for account (E or R)
3)     Amount --- Contains amount
4)     Period     Name -- Contains Numeric Amount.
Cross Tabular Report Look like as follows
Period Name          Feb-2009     Mar-2009
Account Name
Total Revenue          100          90
Total Labor Cost          30          30
Total G&A Cost          20          50
Profit               ???          ??
Need to show PROFIT =Total Revenue- (Total Labor Cost- Total G&A Cost)
at bottom for each period.
I am unable to use calculations because it appears column wise…
Would you please suggest solution for this?
Thanks,
Mahesh.

Hi
Try dragging the data point headings off the top axis and place them to the right of the Account Name. They will all drag together so just moving one will move them all.
If your profit is already calculated and is a data point as you have commented then it too will come over to the left. For displaying it under the other items, a really cool feature about having data points on the left is that you can drag their heading and place it anywhere you want. I will be including this trick in my free March ask Michael webinar. (By the way, if anyone reading this thread you can sign up for my free webinar by clicking here: http://ascbi.com/question.htm)
You should now be able to display your calculated profit as a row underneath the other items. I tried this on my own system and it worked just fine.
Best wishes

Failed to calculate size of Filter in %CHARSET% charset

What does the error "Failed to calculate size of Filter in %CHARSET% charset" actually mean?
We get the error if we want to update a filter to a user account, specifically when that particular user is a member of several (native) groups.

I saw this error after just installing Planning 9.3.1. After some discussion with Oracle support the conclusion was we need to apply Planning patch, 9.3.1.1.1. After applying the patch planning now will refresh security with out the message.
You may have to work through Oracle support to be able to download the patch.

Calculate size of table with BLOB column

Hello,
when trying to calculate the occupied space for a table, I'm using DBA_SEGMENTS, which works fine as long as the table does not have a BLOB column.
As far as I can tell, the size of the BLOB data is stored with the SEGMENT_TYPE = 'LOBSEGMENT', but I cannot find a view that tells me which DBA_SEGMENT row belongs to the BLOB column in the table I'm checking.
To give you an example:
select sum(BYTES)
from DBA_SEGMENTS
where owner = user
and segment_name = 'MY_TABLE'
group by SEGMENT_NAMEreturns 262144
running:
SELECT sum(length(blob_column))
FROM my_tablereturns 821333
There are entries in DBA_SEGMENTS for my user with the type LOBSEGMENT, but I cannot find a way to map the correct DBA_SEGMENTS row to the table I am checking.
Any ideas?
I'm using Oracle 10.2.0.3.0 on Redhat
Thanks in advance
Thomas

hello RSingh,
Once again thanks for your cooperation,
I applied the script you posted, but it is not giving me the size of the folder which is located at a remote machine. Please note the " I need to calculate the size of the folder which is located at a remote machine".and when i applied its path in your script,
it raises "Access is denied" error message.
My path is - '\\ewp-dev18\c$\Attachments'
EXEC getFileProperties '\\ewp-dev18\c$\Attachments'
and this folder does not have any sub folders, it contains only some txt files, image files or some doc files. so no issue of sub folder.
and about my remote server 'ewp-dev18', i have all access and rights, but still raising "Access is denied". why?
do i need to pass any login credential with it ???

How do I re-size all rows evenly? I'm using the ios version of Numbers.

With the new upgrade yesterday it made all of my rows smaller and I'd like to make them all the same size but can't see a way to do that unless I go through every row and drag it but then they're not even. Any ideas or has this not been implemented yet? Thanks.

BrooklynGuy,
There is only one Blank Numbers Template. You can change its orientation from portrait to landscape by clicking on the Print View Icon on the lower left and then selecting the portrait or landscape orientation.
I'm not sure how you got a seperate template for landscape, but it isn't needed.
The truth is that there is a single in-the-box blank Numbers template.
But the OP may be using custom templates. It's what I assumes to be what he does.
When we create a new document or a new custom template, as far as I know, as long as we use the Numbers format, there is no valid reason to ask the app to store the default thumbnails in the file.
Numbers User Guide state :
but, if Numbers is unavailable on the target machine we would be unable to open the Numbers document.
So, I guess that the OP create his templates urging the app to embed the thumbnails and that later, for an unknown reason, the embedded files were deleted.
Here are the two documents contents :
Here is the way to repair a document which loose its embedded thumbnails :
Create a new doc from the in-the-box blank template.
Save it with the advanced options settings.
Then use the often described scheme to reach the doc's internals.
At last, move the thumbnails from the new document to the « broken » one.

How To set memory parameters /calculate size of data files for 100 gb db

Dear all,
I am new in Oracle db admin. I request to all of you buddies to please help in the following query.
For a production database of about 100 GB in archivelog mode and 50 users simultaneously connecting to it. How
to calculate the memory parameters (SGA PARAMETERS ) and size of all users/rbs/temp tablespaces ? I mean to
say how to reverse enginner the sizes.
like - how set settings of following
SGA_max_size=
Shared_pool_size=
db_cache size,=
buffer_pool_size=
db_cache_size=
db_block_size=
log_buffer=
large_pool_size=
Thanks in advance. Please help me in this case

Friend 191264
To tune the SGA parameters is something equivalent to knowledges for a complete course. Really the question is so wide to answer and overall for you that you are new to Oracle. Some people does not like to read documents but in this case you will have to do it.

Calculate size of any shape

Show the size of any two dimensional shape in the unit that's currently chosen (mm2, cm2, inches2, pixel...)

Or since vsize requires data to exist run an analyze or dbms_stats and then see the dba_tables.avg_row_len column value.

Calculate size of attachments FI documents

Dear all,
I need to calculate the size of attachments FI documents. Can I calculate the weight of the attachments in BD? What table stored? And the most important: is there a formula or mechanism to calculate how the base will grow in the future according to documents containing attach?
Were using standard functionality SAP-DB (not external like IXOS).
Thanks!

RZL_READ_DIR_LOCAL
     Export to function the server address,
     The function returns the files.
GUI_GET_FILE_INFO
     Export to function the files (addres + file name), example: folder/file.txt
     The function returns the size
The base will grow regarding the files and the size... if you have a day average you can foresee.
If you don't have a average and the user can upload any number any time, create a program that calculate the size and sends a message (like e-mail) after the server have X megas. And you can create a job to this program to send automaticaly an alert e-mail.
