4 from dual
5 MODEL
6 dimension by (0 d)
7 measures (0 F1)
8 rules iterate(10)
9 (F1[iteration_number] = case
10 when iteration_number in (0,1)
11 then
12 1
13 else
14 nvl(f1[cv()-1],1) * 2 + nvl(f1[cv()-2],0)
15 end
16 )

How can you write "A SEQUENCE OF characters" in sql... ?
Gurus of the afternoon,
A fast if all goes well. I am eager to return all records where a family of field name! = A SEQUENCE OF characters IN THE fnd.description field.
How do I do this in SQL?
How can I write in SQL ' a SEQUENCE OF characters IN per2. As of email_address one ' % the same characters as its in SUBSTR (per2. LAST_NAME, 2, 6) %'...?SELECT DISTINCT fnd.CREATION_DATE, fnd.user_name, fnd.start_date, per2.last_updated_by, per2.last_update_date,per2.employee_number, per2.EMAIL_ADDRESS, per2.full_name, fnd.LAST_LOGON_DATE FROM fnd_user fnd, per_people_f per2 WHERE fnd.employee_id = per2.person_id(+) AND fnd.end_date IS NULL how do I rewrite this..? ** AND SUBSTR(per2.LAST_NAME, 2, 6) != SOME SEQUENCE OF characters IN per2.EMAIL_ADDRESS ** aND per2.EMAIL_ADDRESS LIKE '%priddle%' ORDER BY 2 ASC;
I hope it's unclear! Please ask any questions.
Thanks for the research.
STwo ways:
AND per2.EMAIL_ADDRESS NOT LIKE '%'||SUBSTR(per2.LAST_NAME, 2, 6)||'%'
or
INSTR(per2.EMAIL_ADDRESS,SUBSTR(per2.LAST_NAME, 2, 6),1) = 0

The M-series multiplexer sequencer allows to sequence external multiplexers?
Hello community OR.
I have been using a set of IA-32 M-series cards to scan the independent streams of data to the 32 kech. / s. The source of the signal is a series of very low voltage signals current 256 (action potentials in the brain of a rat in a maze). These signals is stamped by the amplifiers gain unit on a tiny PCB attached at the head of a rat. The signals in the buffer are then sent through extremely fragile 256 cables long 3 meter another set of filters and amplifiers; the results of this stage of MPAs are then sent to my NIDaq cards, and I use the API c my acquisition and analysis.
I want to reduce the number of cables in this package of 3 meters, I'm looking at the possibility of multiplexing. The multiplexing itself seems simple enough, but it seems that demultiplexing is very delicate, requiring a bunch of sample-and-hold amplifiers all synchronized with the sequence door multiplexer. I described the idea more in detail, with a figure, here: http://electronics.stackexchange.com/questions/22521/does-analog-time-division-demultiplexing-need-a...
Someone suggested to me that I'm giving up my own demultiplexing. The fork just signal multiplexed for 32 channels of the NIDaq map AI. Given that map NIDaq multiplexes its inputs through his ADC, it will taste each line only in the window of time when the signal on this line actually carries the appropriate data.
But I think that in order to do this, I would need access to the internal sequence (carries digital signals that address the multiplexer) multiplexers of data acquisition. If I just take the main time base, count the cycles and decode a sequence of door County, then it seems that I may have a problem of phase shift. It is:
How will I know if the DAQ card account in this way:
Time: 0 1 2 3 4 5... 27 28 29 30 31 32 33 34 35
SEQ: 0, 1, 2, 3, 4, 5... 27, 28, 29, 30, 31, 0, 1, 2, 3
Or this way:
Time: 0 1 2 3 4 5... 27 28 29 30 31 32 33 34 35
SEQ: 2 3 4 5 6 7 29 30 31 0 1 2 3 4 5
So, is it possible for the user to have access to these sequence data?
Or is it possible that I could safely count some clock in the map signal and decode in the same way that the card is multiplexer sequencer decodes?
Thanks a lot for any advice you can offer!

Hello
I use Analogtodigital.Vi to convert the pulse of the sequences in digital.signals.I am able to get the representation of digital waveforms of impulses.
But how to count the number of 1 is present in the converted digital waveform. I want to count the number of 1 is present in the digital waveform converted.
Thanks in advance.
Have you tried the block scheme of similar to the Digital.vi of opening?
It creates an array 2D uncompressed 1 and 0, which is the binary 16 bits A/D conversion of each element in the array Y of the input waveform. You can use the DWDT digital Array.vi Boolean to convert a 2D Boolean table. Then convert Boolean values to 1.0 and summarize the array of integers. The sum must be the number of 1 bits in the digital waveforms.
Lynn
Note: The VI attached is saved in version 8.6. When I have it saved for the previous Version a warning was generated about the possible differences in the versions. Let me know if it doesn't work, and you are using which version of LV.

I am writing a query that scans a product Dimension Row_Wid, notes the gaps in the sequence and generates the missing Row_Wids. It loads these 'missing Feds"in a sequence of wid created table to reuse by Informatica transformation of research without bond during the subsequent data loads. Yes, I expect many people asking why I do this. The simple reason is that Informatica has a limit of 2 147 sequence generator 483 647'. I arrived at this upper limit, but my table contains only 2.2 million lines of actual data. I'm trying to reuse these Row_Wids now 'not used '.
I have a job with success the query to find the first ditch and fill some of that gap. Now my next problem is to figure out how to get my request to move away from the next. I can't use the PL/SQL in the query. My client does not allow its use.
I'll paste the code I have now. I need to evolve to the next gap. Suggestions? Help? Ideas?

secconf.Sql. If it will work for upgrades or only for new databases?
Hello
I'm reviewing oracle 11g features and found that few things need special attention, such as checking the settings and the changes in the default profile.
Looking at the secconf.sql file, I found this note
REM only invoked for databases of newly created, not for upgrade of databases
My question is
(1) if I update a database to Oracle 10 G to Oracle 11 G, will, these changes in profile by default and the audit take place or not?
(2) these 11 G changes will happen if we create new databases using DBCA?
Thank you
DelphineIf you take a peek of scripts by calling secconf.sql in 11.2
/rdbms/admin, you see that secconf.sql can be run from catuprgd.sql with the following calling sequence: catupgrd. SQL-> catproc.sql-> catpexec.sql-> execseq.sql-> secconf.sql
You can retrieve it with:
pwd /u01/app/oracle/product/11.2.0/dbhome_1/rdbms/admin [oracle@lx01 admin]$ grep secconf.sql *.sql execsec.sql:Rem Only run the secconf.sql script for new database creations, not execsec.sql: :secconf_name := '@secconf.sql'; secconf.sql:Rem $Header: rdbms/admin/secconf.sql /main/3 2008/10/26 23:05:27 apsrivas Exp $ secconf.sql:Rem secconf.sql secconf.sql:Rem secconf.sql - SECure CONFiguration script [oracle@lx01 admin]$ grep execsec.sql *.sql catpexec.sql:@@execsec.sql execsec.sql:Rem $Header: execsec.sql 12-jun-2006.13:39:34 rburns Exp $ execsec.sql:Rem execsec.sql execsec.sql:Rem execsec.sql - secure configuration settings [oracle@lx01 admin]$ grep catpexec.sql *.sql catpexec.sql:Rem $Header: catpexec.sql 06-jan-2007.20:57:33 rburns Exp $ catpexec.sql:Rem catpexec.sql catpexec.sql:Rem catpexec.sql - CATProc EXECute pl/sql blocks catproc.sql:@@catpexec.sql --CATFILE -X execcr.sql:Rem Run from catpexec.sql (catproc.sql) [oracle@lx01 admin]$ grep catproc.sql catupgrd.sql @@catproc.sql --CATFILE -X
Thus, it seems that catupgrd.sql still works secconf.sql. Given that catuprgd.sql is THE upgrade script (see http://download.oracle.com/docs/cd/E11882_01/server.112/e10820/scripts004.htm#sthref3623), it seems that this secconf.sql is still running.
But this is not the case if you read execsec.sql code and comments:
Rem Only run the secconf.sql script for new database creations, not Rem for upgrades or any other reruns of catproc.sql. The version column Rem in registry$ is NULL while catproc.sql is running the first time Rem on a new database. VARIABLE secconf_name VARCHAR2(256) COLUMN :secconf_name NEW_VALUE secconf_file NOPRINT DECLARE p_version varchar2(30); BEGIN :secconf_name := '@nothing.sql'; SELECT version INTO p_version FROM registry$ WHERE cid='CATPROC'; IF p_version IS NULL THEN :secconf_name := '@secconf.sql'; END IF; END; / SELECT :secconf_name FROM DUAL; @&secconf_file
In the case of database upgrade registry .version $ is not null and above the code will run nothing.sql instead of secconf.sql:
[oracle@lx01 admin]$ cat nothing.sql Rem $Header: nothing.sql 18-oct-2001.09:57:38 Exp $
It is therefore very likely that secconf.sql is not running during the 11.2 database upgrade (I think that the same should apply to 11.1).

Problem with creating a sequence

Repeating the trigger with Start.Retriggerable
I have a DAQ PCI-6259 (M-series card) card I am programming with DAQmx. I would like to know if there is a limit in terms of how close together you can use Extensible triggers. I intend to use a frequency of internal clock to 1us. An asynchronous external TTL signal will be used to trigger a finite sequence of digital output of the 6259. The finished digital sequence is 4 samples of long, so it will take 4us. The edges of the asynchronous trigger will happen on every 100us. I intend to use the property Start.Retriggerable = TRUE trigger so that I can repeat this generation 4 sample every time the external TTL signal is received.
Is 100us too close together? Is there a limit to how closely together, you can repeat a hardware trigger when using Start.Retriggerable = TRUE?
Is it possible to know if my card PCI-6259 even supports the property trigger Start.Retriggerable?
100 US will be very well (time to rearm is the order of a tick or two, 10 timebase s ~ ns).
However, the M series supports digital output directly redeclenchables not. Instead, configure a redeclenchables counter finished output to generate impulses 4 to 1 MHz (this example uses two counters embedded M-series). Use the output of the internal counter as the sample for a task of digital output clock continuous who will repeat your 4 sample sequence.
Best regards

How to generate a trigger when the arbitrary
Hi all
I have a digital output pci card 6534 and an analog output pci card 6723.
I would like to generate a material long pulse sequence timed. The 6534 has 32 MB memory on board, so it is good to do a long sequence. The 6723 will run out of memory if started at the same time. I would therefore trigger the 6723 at a later date. The boards are connected with rtsi.
I see 3 ways to do (well that I know how to do, but the first two would be more elegant):
(1) generate a sequence of digital pulses on ports (i.e. how that), then convert a line of port online rtsi (don't know how to)?
(2) generate a trigger to the arbitrary point on the rtsi lines (don't know how to)?
Go 3) with 1) physically connecting a port to a line PFI on the analog card.
I have not found a way to send a trigger at some arbitrary point with the RTSI. Instead of this I went with solution 3) and related digital outputs analog card PFI channels.
