How can I use multiple row subqueries in update statement
Hai AllI'm using the Group feature in my update statement... and I need to update several lines so I need to use several rows
subquery pls tell me how to use multiple row subqueries in update statement
For example
while I use it like this I got an error
Update dail_att set outtime to (select max (r2.ptime) in the temp_att where empcode = r2.enpno and)
bar code = r2.cardn and group attend_date = r2.pdate by enpno, update, cardn);
Pls tell me how to use for example
Thanks and greetings

Hello
for r2 loop p1
R2 is a line of the cursor,
Max (R2. PtIMe)? It is always equal to r2.ptime if the select statement returns rows.

Please how can I use a value in a table of the adf in an actionListener to a button I created in a popup and thanks
What is your version of JDev?
Actually your question is not clear to me, but as I understand, it is you the table in the page and you have popup inside this popup you have the button you need when you click on the button to read the value of the selected table row. In the listener action button, so if you can get the current row of the table and after that you can get any attribute of the line as:
DCIteratorBinding iter = (DCIteratorBinding) BindingContext.getCurrent().getCurrentBindingsEntry().get("TableIteratorName"); // from pageDef. Row r = iter.getCurrentRow(); Object value1 = r.getAttribute("attribute1"); Object value2 = r.getAttribute("attribute2");

How can I use my photo albums as screensaver with Apple TV 4th gen
How can I use a photo album that I created as a screensaver on the generation of Apple TV 4 because it is not an option in this sense?
What follows is the Apple TV 4 user guide...
Screensavers
Apple TV displays a screen saver when it remains inactive for a predefined number of minutes.
Air screensaver shows beautiful videos of slow motion of the places of the world, upload to an online server, making the screen saver more engaging and dynamic. For the antenna, you can control how many times Apple TV check and download new videos.
Change the frequency of aerial screensaver download. In settings, go to general > screen saver and select Download New Videos, and then select an option.
Return by using Apple TV. When the screen saver is active, press the contact surface to get to some app have been previously using.
Choose a different screen saver. In settings, go to general > screen saver and select the Type. Then select the screen saver you want to use.
Select the photos to display. Many of the screen saver options display a slide show of photos - it can include photos provided by Apple, or your own collection stored in iCloud. To choose which photos are used, in the settings, go to general > screen saver and select the Type. Then choose one of the types of screensaver-photographers.
If you choose my Photos, the Photos app opens. Follow the instructions to put photos as screensaver.
Set the screensaver time-out. In settings, go to general > screen saver and select the setting starts after, and then specify a number of minutes. This indicates to the Apple TV to start the screen saver automatically if the unit has been idle for the specified time.
Activate the screen saver immediately. Press the Home button to go to the home screen (if it isn't already), and then press the button twice.

How can I use my instore credit for a movie
Hello R Larson,
I see that you are wanting to use a store credit for a movie. I'll be happy for you have said in the right direction. First of all, let's see if we can find out if the credit is a credit of iTunes gift card or a credit from the Apple Store. This article will help you determine what may be:
What kind of card do I? -Apple Support
If credit is iTunes, you can just check your balance using the instructions found in the section below and use to either rent or buy a movie to display:
See your credit balance - Apple Support iTunes
If the store is an Apple Store Gift card credit, you would not be able to use iTunes to watch a movie.
I hope this helps. See you soon!
