What is the requirement?
What you posted is an attempt to meet a requirement, but if this is the right way or not, it is not the condition. A response is not the same as a question.
Whenever you have a question, please post a small example of data (CREATE TABLE and only relevant columns, INSERT statements) for all of the tables involved and the results desired from these data.
Explain, using specific examples, how you get these results from these data.
Always say what version of Oracle you are using (for example, 11.2.0.2.0).
See the FAQ forum: https://forums.oracle.com/message/9362002#9362002
FULL OUTER JOIN is never the only way to get any results. Sometimes, it's the best way, but sometimes there are other means that are simpler and more effective. The set operators, such as the UNION (as suggested earlier) sometimes are a better solution.

How can I get several hyperlinks to display in the query output?
I uses two tables to list all a school sport teams. The table of sport lists all team data aggregated by gender. The second table uses the sportID of the first table to associate a team calendar. The problem is not all the teams do not have a calendar.
I'm trying to post a link to these teams with schedules. I compare the two tables, the sport and the calendar and a CFIF statement allows to compare the 2 sportIDs in the output to determine the teams who have a schedule. If the two sportIDs corresponds to a hyperlink is displayed.
Unfortuanetely, only one link will be displayed, even if there should be three links. Here is my code:
Table to display aggregated by gender teams
"< name cfquery ="getSports"datasource =" #application.database # "" >
Choose between the sexes, team, levels, sportID
sports
Group sex, team, levels, sportID
< / cfquery >
Table used for the sportID of already created calendars
< name cfquery = "getID" datasource = "#application.database #" >
Select sportID
annexes
SportID group
< / cfquery >
I then compare the sportIDs and if they match, I then display a hyperlink
"< cfoutput query ="getSports"group 'sex' = >"
< h1 "> teams #gender < / h1 >"
< ul >
< cfoutput >
< li >
< cfif getID.sportID EQ getSports.sportID > <a href = "teams.cfm? sportID = #sportID #" >< / cfif >
#team # < cfif levels GT "" >(#levels#) < / cfif > //levels is used to differentiate the J.V. and Varsity. "." Usage levels not all of the teams
< cfif getID.sportID EQ getSports.sportID > </ a >< / cfif >
< /li >
< / cfoutput >
< /ul >
< / cfoutput >
How can I get the other teams to display their links?
Thank you gentlemen, since everyone was suggesting an outer join, I took out my trusty Manual of ColdFusion and learn about them. I've added the sum() for the query:
Select sports.gender, sports.team, sports.levels, sports.sportID, sum (schedules.sportID) AS expected
sports
opening hours of the outer join left on sports.sportID = schedules.sportID
Group of sports.gender, sports.team, sports.levels, sports.sportID
So add the following to the output:
And everything works perfectly. Once again, life is beautiful!

How can I get my two headphone microphone jack to work with a single shot?
My 510 had two jacks, but my 520 has only one. I want to use the microphone on my headset... even if I can't use the headphone speakers at the same time. How can I get my laptop from the microphone to the microphone headset? The built-in function takes too much background noise.
Thank you.
Abigail
Dear AbigailCW,
I'm afraid that it will not work. Two jacks, one of which was a standard on older PCs, serves as input and audio output microphone, in short, audio out, voice went in through your microphone. This has changed now because of recent trends and can be inconvenient for most users.
I solved this problem by buying a USB soundcard with these two entries, and it cost me about US $ 10. As its USB cards helps stimulate an additional gain so I better sound now than ever. May be worth it.
Best regards.

I have two Apple ID. How can I get rid of one?
I have two Apple ID. How can I get rid of one?
Hello Terri108,
Thank you for using communities of Apple Support.
I understand your message that you have two Apple ID and want to get rid of one. First of all, any purchase that you have made with your ID first Apple won't be available on the second Apple ID and vice versa. If you only want to use an Apple ID, you must choose them and then purchase and download all the apps the other Apple ID that you choose.
You could also do for the two the same Apple ID passwords. In this way all the apps you have downloaded to your devices can be updated, and you do not have to remember to separate the 2 passwords.
Best regards

How can I get rid two tabs to open when I first open Firefox?
When I first open Firefox I get my home page in a tab, but also another tab opens. This one is set to Facebook. How can I get rid of the opening automatically second tab?
You get two pages if you launch a new window using either:
- CTRL + n
- button '3-bar' menu > new window
If Yes:
Check the settings of your home page to see if you have several home tabs. A vertical bar (|) is used between the addresses. This article shows you where to check them in the Options dialog box: start-up, homepage, tabs and download settings. This article has more background on several tabs home: How to set the home page.
If not, or if the Options dialog box is correct:
Add-ons - can display tabs at startup or in a new window. If you check the address of the Facebook page, this is the URL to normal Facebook (https://www.facebook.com/) or to a different address?
Do you have any extensions related to Facebook? You can view, disable and often remove the extensions on page modules. Either:
- CTRL + SHIFT + a
- "3-bar" menu button (or tools) > Add-ons
In the left column, click Extensions. Then, when in doubt, turn off.
Often, a link will appear above at least an extension disabled to restart Firefox. You can complete your work on the tab and click one of the links in the last step.
Any improvement?
