How to count number of colums ina sql database

is there a command to find out the length of a column,using rs.next possible???

is there a way of finding out the number of rows in a
database??See my first post for the number of rows in a table.
If you want to get the total rows in an entire database (cant think why) it should be possible with DatabaseMetaData.getTables() and do a SELECT COUNT(*) for each table then add the results.

How to count number of rows in table

can I get number of row in table except Count(*) in pl/sql
is there any other way

Also posted and answered here
how to count number of rows in table
count(*) will be the fastest way. It is only slow if the table has a vast number of rows, in which case why do you need to know the tables has 73552436467721 rows and not 73552436467737 rows. It doesn't seem to be much use. Either that or you are counting them a lot, which again seems rather pointless.

How to Count Number of completed line items in past 6 months / 12 months ?

How to Count Number of completed line items in past 6 months / 12 months ?
Hi,
I am trying to count "Number of Completed Line Items in Purchase Order Document" for my Key Figure ZPO_CNT.
Purchase Order document = ZEBELN
Line Item = ZEBELP.
I need to find and count if the Line Item has been received in the past 6 months from today and similarly in the past 12 months.
I have "Delivery Completed" field, ELIKZ.
So, based on this would I be able to calculate it in Query Designer?
If so, Please let me know how

Hello Deva
If youe want to calculate the completed line item for last 6 or 12 month then i think u will be displaying the query data for these montrhs...create a customer exit to give you date range and restric it in filter area....
Now Choose any of the below option
1. I would suggest to implement an additional key figure "counter" in cube and fill values with one for which delivery is completed.
Now use calculated key figure in Query Designer based on logic
IF counter = 1 THEN counter ELSE 0
OR
2. create a formula variable based on ELIKZ and use replacement path variable, it will display you no. of docs for which delivery is completed....
Award points if it solves your problem
Revert back in case of further assistance...
Thanks

How to delete number (00) in a SQL Server column ?

how to delete number (00) in a SQL Server column ?
example :
column : Births before   Births
  after
                   199900
        1999

    2004
help query

You use REPLACE function to selectively replace text inside a string in SQL Server. The REPLACE function is easy to use and very handy with an UPDATE statement.
SELECT Replace(births, '00', '')
or
update .....
Also you can use STUFF()
This function can be used for delete a certain length of the string and insert a new string in the deleted place.
Select STUFF ('199900', 5, 2, '')
--result 1900,1982,....

How to count number of ones in table

Hello,
i created one table 16x32 each cell is updating 1 byte of data,how to count number of one in all cell,and is it right way to calculate check sum??
thank you

The simplest way is to call GetTableCellRangeValues with VAL_ENTIRE_TABLE as the range, next summing array elements.
But I don't understand your comment on checksum, so this may not be the more correct method for your actual needs: can you explain what do you mean?
Proud to use LW/CVI from 3.1 on.

Hi Experts,
I dont have a defined Restricted key figure yet.
I have populated 0COMPL_DEL(Delivery Completed Indicator) and 0EBELN (Purchasing Document Number) and 0EBELP (Line Item Number in Purchasing Document) .
This is what I think how I need to calculate:
Number of completed line items in past 6 months:
If Delilvery Completed Indicator (0COMPL_DEL) = x, calculate No. of Line Items (ZPO_CNT) from 0CALDAY to 6 months
and
Number of completed line items in past 12 months:
If Delilvery Completed Indicator (0COMPL_DEL) = x, calculate No. of Line Items (ZPO_CNT) from 0CALDAY to 12 months
Please let me know if the logic is correct. If so, how I can create this in report

Hi Dariel Pérez ,
By executing the Querey I'm able to get the State and num_cube instances but when I call this Query in BPEL by using DB adapter I get the following error
BINDING.JCA-12563 Exception occured when binding was invoked. Exception occured during invocation of JCA binding: “JCA Binding execute of Reference operation ‘CountReq’ failed due to: Pure SQL Exception. Pure SQL Execute of SELECT (CASE WHEN STATE=1 THEN ‘OPEN AND RUNNING’ WHEN STATE=2 THEN ‘OPEN AND SUSPENDED’ WHEN STATE=3 THEN ‘OPEN AND FAULTED’ WHEN STATE=4 THEN ‘CLOSED AND PENDING’ WHEN STATE=5 THEN ‘CLOSED AND COMPLETED’ WHEN STATE=6 THEN ‘CLOSED AND FAUTED’ WHEN STATE=7 THEN ‘CLOSED AND CANCELLED’ WHEN STATE=8 THEN ‘CLOSED AND ABORTED’ WHEN STATE=9 THEN ‘CLOSED AND STALE’ WHEN STATE=10 THEN ‘NON-RECOVERABLE’ ELSE STATE || ” END) AS STATE, COUNT(*) AS NUM_OF_CUBE_INST FROM CUBE_INSTANCE GROUP BY STATE; failed. Caused by java.sql.SQLSyntaxErrorException: ORA-00911: invalid character . The Pure SQL option is for border use cases only and provides simple yet minimal functionality. Possibly try the “Perform an operation on a table” option instead. This exception is considered not retriable, likely due to a modelling mistake. To classify it as retriable instead add property nonRetriableErrorCodes with value “-911″ to your deployment descriptor (i.e. weblogic-ra.xml). To auto retry a retriable fault set these composite.xml properties for this invoke: jca.retry.interval, jca.retry.count, and jca.retry.backoff. All properties are integers. “. The invoked JCA adapter raised a resource exception. Please examine the above error message carefully to determine a resolution.
Any Suggetions.

Hi,
Initialise one variable TOT_ROWS to 0.
Then in the for loop
tot_rows := tot_rows + +1 ;
so after for loop the value in the tot_rows will be the total records..
If u want it to get this value in the calling procedure of this , just declare tot_rows parameter as out parameter.
For sum of a column:
Initialise a variable sum_col to 0.
In the for loop
sum_col := sum_col+I_info.column_name
aprameter if u wish return this value as out..
I think this wil give u the o/p..
cheers,

How to count number of records for a field based on condition?

Hi guys,
I want to know how to find count of records coming from the database for a particular field based on some condition.
I need to use this count to suppress some headers. Because of this i am not able to use running totals. Is there any other way?
Ex scenario:
I have account number and currency fields, those are coming from database. And i need to count the number of accounts whose currency is not Euro.
Thanks in advance,
Vijay.

A simple formula can do that:
//Formula begin
if {your account field}<>"Euro" then 1
//Formula end
This formula can be summarized. (by group or report)

How to count number of autoextents that had took place between a period.

urgent question
Hi all
how to provide me a report for getting the result of the Disk Drive Space usage (drive letter) that shows how quickly the space is being used up by the database(dbf files).
Or how to count the number of autoextents that had took place between a certain period of time.
either by cmd promt or OEM would be fine
Oracle database 10g(single instance)
OS:Windows 2003 server
thanks
Anto

hi justin and Pavan
First Thanks for your immediate responce,
Secoundly client has asked for the growth report at the OS level and not at the database level. but the growth is with respect to the autoextent feature that oracle has over the datafiles.
I was thinking that i could get a view or some history log to get this data retrieved from the past may be of a months data.I normally manually check the data base growth with the following script
SELECT total_space,free_space,
(NVL(total_space,2)-NVL(free_space,2) ) used_space
FROM (select round(SUM(Bytes/1024/1024/1024),2) Total_space
from DBA_data_files
(select round(SUM(Bytes/1024/1024/1024),2) free_space
from DBA_free_space
but this is Oracle DB level.
Any ideas for the report.like a query or somewhere in OEM
Thanks
Anto

How to count number of lines in a file?

I am using a BufferedReader to read my file, but I like to know how to count the number of lines in a file is there a way to do that in Buffered Reader or do I have to use FileInputLineStream?

Well, if you know how to read one line with a Buffered reader, and you know how to keep reading lines until you run out, then all you have to to is initialize a counter to zero before you start reading, add 1 to it each time you read a line, and then examine its value when you're done.
Try that, and post again if you get stuck.
Just be careful how you construct your loop. "Off by one" errors are a common way to get bitten. It could happen if you count what you think is the last line, but you've actually already counted all the lines and you end up counting one extra for "there are no more lines".
