Problem with a Cartesian join

Hello

I'm on Oracle 10.2.0.4.

I have a problem with a simple Cartesian join. Is it possible to have a Cartesian join? whether a table has data and another table has no data, I take a Cartesian join (no join condition), I want to see all records from a table and values NULL for columns from the other table.

For example

SQL > create table T1 (id number, emp_name varchar2 (30));

Table created.

SQL > create table T2 (sp_name varchar2 (10), sp_desc varchar2 (10));

Table created.

SQL > insert into T1 values (101, 'AAAAA');

1 line of creation.

SQL > insert into T1 values (102, 'BBBB');

1 line of creation.

SQL > insert into values of T2 ('TBT', 'Important');

1 line of creation.

SQL > insert into values of T2 ("XYZ", "Not good");

1 line of creation.

SQL > commit;

Validation complete.

SQL > select t1.id, t1.emp_name, t2.sp_desc

2 from t1, (select sp_name, sp_desc from t2 where sp_name = "OTC") t2;

ID EMP_NAME SP_DESC

---------- ------------------------------ ----------

AAAAA 101 Important

Important 102 BENAMER

SQL > select t1.id, t1.emp_name, t2.sp_desc

2 from t1, (select sp_name, sp_desc from t2 where sp_name = "ZZZ") t2;

no selected line

SQL >

In the second query (where no line is selected), I want to see all the records in the table T1 and NULL values in columns from the alias of table T2.

How can I do?

Thanks in advance

The ANSI syntax can help here.

Select t1.id, t1.emp_name, t2.sp_desc

from t1

outer join t2 left t2.sp_name = "OTC";

ID EMP_NAME SP_DESC

---------- ------------------------------ ----------

AAAAA 101 Important

Important 102 BENAMER

Select t1.id, t1.emp_name, t2.sp_desc

from t1

outer join t2 left t2.sp_name = "ZZZ";

ID EMP_NAME SP_DESC

---------- ------------------------------ ----------

AAAAA 101

BENAMER 102

Problem with ANSI OUTER JOIN

Hi all

I have issues with the help of ANSI LEFT JOIN compared to Oracle (+). Below test I did the same thing.

      create table emp (emp_id number(10), emp_name varchar2(50));
      create table courses (course_id number(10), emp_id number(10), course_name varchar2(50));
      
      INSERT INTO EMP values(1,'A');
      INSERT INTO EMP values(2,'B');
      INSERT INTO EMP values(3,'C');

      INSERT INTO COURSES values(1,1,'ORACLE');
      INSERT INTO COURSES values(2,1,'JAVA');
      INSERT INTO COURSES values(3,3,'C#');

      --*Query 1
      SELECT a.*, b.*
      FROM EMP a  LEFT JOIN COURSES b 
      ON a.emp_id = b.emp_id
      AND a.emp_name = 'A'

      --*Query 2      
      SELECT a.*, b.* 
      FROM EMP a, COURSES b 
      where a.emp_id = b.emp_id(+)
      and a.emp_name = 'A'

Here Query1 return all records of 4 same records regardless of emp_name = 'A' where as Query2 returns 2 records of ep_name = 'A' which is correct.

Is this correct? I'm confused if you use the standard ANSI OUTER JOINS or not.

I am using Oracle 11g

Thank you.

Change your AND WHERE, in the style of ANSI, select:

SELECT a.*, b.*
FROM EMP a  LEFT JOIN COURSES b
ON a.emp_id = b.emp_id
WHERE a.emp_name = 'A'

Filters in the clause are those who use the (+) in the Oracle syntax.
Filters WITHOUT (+) in the Oracle syntax should be in the WHERE clause using the ANSI syntax.

Problem with LEFT OUTER JOIN

Hello

I am in charge of the migration of a SQL Server 2000 database to Oracle 11 g, under what I also migrate some predefined queries, that my client has. However I can't seem to get the syntax right and it keeps failing. Could you please help me? Thank you.

Query:

SELECT *,(select r.recsolins from gx.repara r where r.percod=c.percod and r.concod=c.concod and r.rectpo='I' and r.recsts='F' and r.grppercod=10 and r.recnro=(select max(t.recnro) from gx.repara t where t.percod=c.percod and t.concod=c.concod and t.rectpo='I' andt.recsts='F' ) ) as NROID
FROM gx.CONABO c, gx.abonad a  
LEFT OUTER JOIN gx.CALLES y ON  y.dptocod=10 and y.ciucod=524 and y.CALCOD=A.AboCalEsq1, 
LEFT OUTER JOIN gx.CALLES Z ON  z.dptocod=10 and z.ciucod=524 and z.CALCOD=A.AboCalEsq2 
,gx.calles x WHERE c.PERCOD in (10,60) and CONSTSHAB in ('C','D','P')

x.dptocod=10 and x.ciucod=524
and x.calcod=abocal
order by c.percod,c.concod;

The fields are correct, but I get not found when expected in FROM clause.

Problems with Server 2008 R2 Kerberos with Mac and CentOS machines? Need to re - join domain

We are having a problem with our Mac and Linux / CentOS machines constantly having to be re-attached to our AD domain.
We are able to join machines to the domain successfully, but after a few weeks or if authentication is broken and we again join them to the domain.
I see Security event logs on our domain controller when kerberos authentication fails.
On the linux server - I see this message in the logs
-binding failed: server not found in the kerberos database.

I'm guessing this has to do with Server 2008 R2 and incompatible mac / linux versions.

Any ideas?

As you can see in 10g that I don't have the last row, it seems that Oracle 10 g does not recognize the LEFT OUTER JOIN.

Is this a bug?, Metalink says that sometimes we can have an ORA-0600, but in this case there is no error results returned, just incorrect.

Help, please.

Kind regards.

What about try the original Oracle method for outer joins? Using (+) without the extra space

XMLTABLE(...COLUMNS ... id XMLTYPE PATH ... ) x,
XMLTABLE(... PASSING x.id ...) (+) y

problem with join of two tables
Hi, consider the following data
```
WITH data AS
(
  SELECT 123 cid, 'aaa' isi, 'kkk' sud, 'ttt' ri FROM dual UNION ALL 
  SELECT 222 cid, 'bbb' isi, 'gggg' sud, 'hhh' ri FROM dual

) ,
data2 AS 
(
  SELECT 'aaa' isi, 'yyy' sud, 'ooo' ri FROM dual UNION ALL 
  SELECT 'qqq' isi, 'ggg' sud, 'ooo' ri FROM dual UNION ALL 
  SELECT 'uuu' isi, 'ppp' sud, 'ttt' ri FROM dual UNION ALL
   SELECT 'ppp' isi, 'mmm' sud, 'nnn' ri FROM dual 


)
```
what I want to do, is to join data2 with data by isi, ri or southern id table and produce this output.
```
 cid  txt
 ===  ====
 123  aaa
 222  ggg
 123  ttt
```
It's how I got the above output:
first try to join isi in database2 with isi in "features" and discover if line matches. If this is the case, display the cid of the data table and the use of the value to match.
e.g. in the first line of table data2, we can see that isi = aaa matches line an isi data table. If the output displays 123 and value aaa.

If the rank table two of the Data2 isi = qqq. When join them with the data table, we find not all isi with qqq. in this case, it must join with column of South. We can see that South = ggg data2 games
the second line in the table of output so will bee 222 and value ggg.

now, take a look at the third row in Database2. ISI = uuu is not found in the data table when join them. then try to join to the South. South = ttt is also not found in any row of the data table. so join with ri. We
can see that ri = ttt data2 matches with ri = ttt in the table of data online 1. Therefore, we display the value.

can someone help me write a sql query that joins these two tables by isi. If no line found then join South, if no found rows then join in ri? Thank you

Hi Frank, data2.sud = 'Gay' (4 characters) assume to be South = "ggg". by mistake, I type extra g.

I have another question about the request. What happens if I want to bring rows of data.2 even if they do not exist in the data table for the entire column was join?
for example, I want to show this:
```

123  aaa
222  ggg
123  ttt

the columns of the last row of data.2 does not match any column in the data table. in this case, I want to make but cid will be null. I tried outer join on your request, but it looks like I can not clause or with outer join

,     CASE
          WHEN  d1.isi = d2.isi  THEN  d2.isi

              OR     d1.ri(+)     = d2.ri
;
```
How can I re - write the query for this case? Thanks again for your help
Here is the outer join syntax:
```
SELECT     d1.cid
,     CASE
          WHEN  d1.isi = d2.isi  THEN  d2.isi
          WHEN  d1.sud = d2.sud  THEN  d2.sud
          WHEN  d1.ri  = d2.ri   THEN  d2.ri
                                        ELSE  d2.isi
     END     AS txt
FROM          data2     d2
LEFT OUTER JOIN     data     d1  ON     d1.isi     = d2.isi
                       OR     d1.sud     = d2.sud
                       OR     d1.ri     = d2.ri
;
```
The + sign for outer joins only works with the old join syntax, non-ANSI. Do not try to mix the two different ways to do joins.

Not to mention that the outer join, don't forget to change the CASE expression, to include the new possibility of any columns 3 join matching.

Problems with counter on 9411

I am a new user of Labview, so it's a little intimidating. I am using a cDAQ-9188 with several modules but I have problems with one is the 9411 is used to measure the speed off the coast of a torque meter.

I joined the program I put in place. What I want to do is to measure the number of edges on a 3 second interval so that I can divide by the number of pulses/turn * 60 * 1/3 to receive the RPM. However, the number of edges behave linearly as I expected. I measured the speed of the shaft with a light strobe and represented graphically it vs the number of edges. The results are attached to the excel file.

What Miss me? The number of edges should not increase as speed up the tree, or I'm going about this all wrong and is not what I think I am?

Thanks in advance.

Ahh ok, that make more sense - it seemed like a strange to report a couple measured, way but now I understand that your torque sensor also rpm through this collection of speed option and that's what you ask the subject (I can't see not how pulses/turn the sensor is on the site Web of Honeywell however, do you know offhand?).

The software timing 3 seconds will implement much of the variability in your measure but would not explain the strong negative correlation between the RPM and the speed sensor (we're talking several ms of non-determinisme for a second window 3) output frequency. Finally, you'll want to solve this problem as well, but it is not your problem right now (as an aside - it would be actually more accurate to measure the frequency of the signal encoder using the 80 MHz as a reference time base and average the result on a second window 3, the general idea is sort explained in manual of 9188 here but I digress).

I think it is more likely that the signal from the speed sensor is a bit noisy (pretty typical of optical encoders) and then transitions the 9411 is picking up multiple edges. A slower RPM equals longer transitions and therefore more false edges. It is just a hunch, but that's what I can think of on the top of my head that could be causing what you see (if read number of pulses is higher than what you expect, given the pulses/turn of the sensor through all ranges of RPM that it would support my theory). If you want to ignore the method of measurement for a second and try to solve the problem of noise (assuming there is one), you can add the following property node to your existing code before you begin the task:

You can start by setting MinPulseWidth to 6.4us (which is one of the built-in clock dividers available for PFI filters on the 9188). You want the MinPulseWidth be short enough to ensure detection of a legitimate impulse, but long enough to block all wrong edges that occur during transitions.

ENVY dv6-7320el: problems with touchpad

Hello

I'm new here, so I don't know if this is the right place for this question, but here goes:

I had problems with my touchpad, precisely with the two-finger-roll. It would sometimes stop working, but then set a few minutes. Today that work completely collapsed. I have read suggestions on how to solve this problem, I tried the HARD RESET, it did not help, I tried to juggle synaptics in Panel, which did not help either. Now, I have managed to completely remove the synaptics and cannot install it back.

Can someone please help? The two-finger-roll was my main way of getting around, I feel so lost without her.

model: dv6-7320el

Thank you!

Bob

Problem with router SPA2102 Battlefield 2?

I have problems with my Battlefield 2 (all versions). I have the SPA2102.

EDIT: The game freezes when I click to join a server, nothing happens.

I can play other games online.

When I try the demo version which im using this router, it does not work.

But when I try with the same laptop in other places it works completely fine.

I set up a static IP address and forwarded my ports to help

http://www.PortForward.com/English/routers/port_forwarding/Linksys/Spa-2102/Battlefield_2.htm

What else can I do to make it work?

I am running Vista 32 bit.

Thank you in advance!

Basically the SPA2102 is not design to handle the heavy traffic. This unit is designed to route traffic for VOIP devices and not for game features.

Cannot install Vista service pack 2 is 800f0a09 error code with the message that there are problems with the driver for dell latitude

Original title: why I get error code 800f0a09 to upgrade to windows vista service pack 2

I have a laptop del that is running on Windows Vista Edition Home Premium. I tried to download itunes but it requires service pack 2. Whenever I try to update to service pack 2, I get the message following error code 800F0A09. He also mentioned problems with the driver for dell latitude. What can I do to fix this please.

Thank you

You can not install Vista Service pack 2 and get the error with code 800f0a09 and the message that there are problems with the driver for dell latitude.

The problem may occur if some of the components of the update are corrupt.

What is the full error message that you receive?

I suggest you follow the steps mentioned below to check if the problem is with the update components:

Method 1: Reset the update components

IHAVE problems with mywireless and access point

I have problems with my wireless

Hello

There are hundreds of models of Points of access configured on systems with different computers in different variations, there may be hundreds of reasons why it does not work.

Please, help us to reduce the factor of "guessing game" to provide assistance and give the relevant details of your computer systems.

-----------------------------

There is an inherent Catch22 to attempt to repair a computer wireless through wireless. Given that the without wire is not connected to the source, there is no interaction between the wireless source and the Wireless Client and no frame of reference to find what works and what does not.

As a first step, I will temporarily move the computer to a place close to the wireless router and plug with a wire.

When he works with a wire, switch Off the Wireless Security in the router, disconnect the wire and try to make wireless work. This must be done when the computer is always close to the wireless router to compensate for the weak, and or blocked the signal that could be part of the problem in the new suite spot work.

In the computer itself.

Most laptops have a physical switch for the wireless card. Read the manual of the computer and make sure that the wireless adapter is on.

Check the Device Manager for the wireless card valid entry.

http://www.ezlan.NET/Win7/net_dm.jpg

If there is no valid entry, remove any entry from fake and re - install the drivers for the wireless card.

Check network connections to make sure that you have a network icon/entry wireless connection, and that the properties of the icon (right-click on the icon) are correctly configured with the TCP/IPv4 protocol in the properties of network connections.

http://www.ezlan.NET/Win7/net_connection_tcp.jpg

Make sure that if there is Wireless Utility a utility vendor is not running with the native Windows wireless utility.

Make sure you firewall No. preventing / blocks wireless components to join the network.

Above everything is OK and it connects to the wireless router. Log in from any computer which is, or can be connected to the router with a wire wireless, disable wireless security, make sure that the wireless streaming is enabled and try to connect with no. wireless security.

When the work turns on the Wireless security.

Note * people sometimes make mistakes in writing and retype the password for security.

Another way is to copy in the menu of the router and then paste it when asked of the wireless card.

Problem with access: local only for wireless in Vista

A few weeks ago, we got a new router at home. It works fine, but a few days ago, my computer suddenly could no longer access the internet wireless on this subject. (He had been able to before). Other computers in the House can use it for the wireless, and my computer can get on the internet by cable. My computer can also access wireless to other places, but not at home, and more.

So far, I tried everything what I found on the internet to solve the problem without success. I tried:

1. the solution proposed on this page http://support.microsoft.com/kb/928233.

2. make sure that windows is completely updated.

3 disable IPv6 and IPv4 (although not at the same time).

4 turn off the power management feature that allows the computer to turn off the wireless card.

5. disabling and re-enabling the network card.

so far, nothing has worked. Can someone, please?

Hello

In most cases, this problem is created by the problem with wireless security.

Try to connect with the security temporarily turned off.

Or firewall blocking local traffic.

Wi - Fi in general.

These steps and tell us where is the breaking point.

Check the Device Manager for the wireless card valid entry.

http://www.ezlan.NET/Win7/net_dm.jpg

If there is no valid entry, remove any entry from fake and re - install the drivers for the wireless card.

Check network connections to make sure that you have a network icon/entry wireless connection, and that the properties of the icon (right-click on the icon) are correctly configured with the TCP/IPv4 protocol in the properties of network connections.

http://www.ezlan.NET/Win7/net_connection_tcp.jpg

Make sure that if there is Wireless Utility a utility vendor is not running with the native Windows wireless utility.

----------------

Make sure you firewall No. preventing / blocks wireless components to join the network.

Some 3rd party software firewall continue to block the same aspects it traffic Local, they are turned Off (disabled). If possible set up the firewall correctly, otherwise totally uninstall and get rid of its remaining processes that permit the own local network traffic flow.

If the 3rd party software is uninstalled, or disables, make sure Windows native firewall is active .

---------------------------

Stack TCP/IP work should look like.

Right-click on the wireless network connection card, select status, details and see if she got an IP address and the rest of the settings.

http://www.ezlan.NET/Win7/status-NIC.jpg

Description is the data of the card making.

The physical address is MAC of the card number.

The xx must be a number between 0 and 255 (all xx even number).

YY should be between 0 and 255

ZZ should be between 0 and 255 (zz all the same number.)

The date of the lease must be valid at the present time.

* Note 1. IP that starts with 169.xxx.xxx.xxx isn't valid functional IP.

* Note 2. There could be an IPv6 entries too. However, they are not functional for Internet or LAN traffic. They are necessary for Win 7 homegroup special configuration.

---------------------------------------------------

A message in the small window that says connected wireless doesn't means that you are really a valid functional connection.

Above everything is OK, you must be able to connect to the router.

Connection to the router means that you can enter the IP of the router base in an address bar in one go, being able to connect and configure the router menus see.

If it doesn't connect to the router, journal newspaper from any computer that can connect to the router wirelessly with a wire, disable wireless security, make sure that the wireless SSID broadcast is enabled and try to connect with no. wireless security.

Enable security wireless after you eat to make a functional connection.

Problems with internet access, troubleshooting, Windows 7 does not work.

Hello, I have recently started up to Windows 7 on a partition of Windows 10, because a game wasn't working properly on Windows 10 system (has notified downgrade after a one hour session troubleshooting).

I don't know if the game is causing these issues or anything else, but my internet connection goes away, even if the internet bar shows that it has internet.

Right now, I'm typing this, it says I have a problem.

Also, I have troubleshooted a lot of times, with the answer is:

This happens at random, or whenever I join a game for Minecraft.

Does anyone know the solution to this problem?
