My husband doesn't like the itunes account is under my name. I have a way that he can have his own name and sign on with her and still exist on the family account? Also, have we HAVE two-step verification? It's a real pain.
Yes it can have its own ID and share your content via the family sharing, he needs to sign out of your ID and to create his own, then one of you needs to invite another family sharing.
You don't need to use 2 verification step, if you want you can disable to my Apple ID

by comparing the value to the variable null
Hey guys, quick question. I just want to see if my understanding of the code below is correct:
Declare
v_variable varchar2 (100)
Begin
v_variable: = null;
If v_variable = 'test' then
message ('test');
end if;
If v_variable! = 'test' then
message ('test2');
end if;
If my interpretation is correct, "test2" message should print but wont 'test' or is it possible that I could get an error if we cannot compare with null values?
Thank you
Thank you.
End;You must compare the values null, is null. A comparison of null = or! always = the NULL value and thus you reach your outings:
$[CHE_TEST@asterix1_impl] r 1 begin 2 if null = null then 3 dbms_output.put_line('result: true'); 4 elsif null != null then 5 dbms_output.put_line('result: false'); 6 else 7 dbms_output.put_line('result: else'); 8 end if; 9* end; result: else
The two if the conditions are evaluated to NULL, then the else branch is executed.
acutally null = null evaluates to null as you can see:
$[CHE_TEST@asterix1_impl] r 1 declare 2 bres boolean; 3 begin 4 bres := null = null; 5 if bRes is null then 6 dbms_output.put_line('Result: NULL'); 7 else 8 dbms_output.put_line('Result: NOT NULL'); 9 end if; 10* end; Result: NULL

By comparing the value 'sets '.
Hello
I have a table TAB1 resembling:
I would compare the values separated by commas of DESCRIPTION field with values separated by commas of a user input string. It would be something like:COL DESCRIPTION ---- ----------- 1001 10,11,12 1002 10,11 1003 10 1004
If the user enters anything, the result of the query would be 1001, 1002, 1003, 1004SELECT COL FROM TAB1 WHERE <user_input> IN DESCRIPTION
If the user enters "10" the result of the query would be 1001, 1002, 1003
If the user enters the "11" the result of the query would be 1001, 1002
If the user enters 10 ', 12' the result of the query would be 1001
How can I apply this in Oracle 10 g?
PS: The comma separate values in the DESCRIPTION field and user input are always sorted/ordered!
Thanks in advance,
Peter
Published by: user3764335 on June 7, 2011 02:53You can try something like
Where ','||description||',' like '%,'||replace(user_input,',',',%,')||',%'

How to compare the value of two combo
I have two Combo Box (cbFirst & cbSecond). I want to compare the value that has been selected by the user and according to the result, the output is displayed. In the two combo box, I have provided the value.
Here is my code:
var a: number;
var b:Number;function First(evt:Event):void {}
a = evt.target.value;
trace (a);
}
cbFirst.addEventListener (Event.CHANGE, first);function Second(evt:Event):void {}
b = evt.target.value;
trace (b);
}
cbSecond.addEventListener (Event.CHANGE, second);If (a > b) {}
trace ("more")
on the other
trace (b is higher);
Trace the statement inside the functions work very well and the value correct a & b is printed. But the comparison in the if statement does not seem to work. Could you please help me.
There is a typing error. Fix it or delete it:
var a: number;
var b:Number;function First(evt:Event):void {}
a = evt.target.value;trace (a);
compareF();
}
cbFirst.addEventListener (Event.CHANGE, first);function Second(evt:Event):void {}
b = evt.target.value;
trace (b);compareF()
}
cbSecond.addEventListener (Event.CHANGE, second);function compareF() {}
If (a > b) {}
trace ("more")
on the other
trace (b is higher);
}

Hello
Is it possible to compare a null to null...
Example of
---------------------------
Indicator number;
If null = null then
flag = 1;
on the other
flag = 0;
end if;
---------------------------
Thank you.Hello
Use "is null".
For example:
declare
VARCHAR2 (10) variable;
Start
If the variable is null then
dbms_output.put_line ('variable is null');
on the other
dbms_output.put_line ("'variable is non-zero");
end if;
end;By comparing the value null = null will not work.

Hey there. I installed a new version of Netbeans and he asked me to import files, resources, etc. from the old version, so I agreed. However, when I open the old version that I realized all JavaFX projects contained errors. Then I open the properties of the project-> libraries section, it says broken reference: javafx.classpath.extension in the compile tab. I don't know why I'm dealing with this error, but I guess the reason is that I installed the latest version of Java with the new Netbeans import process caused what is happening. I would appreciate for any relpy. Thanks anyway
EDIT: I'm impossible to import the screenshot, so you can see the same issue here
EDIT 2: Here you can also see the UPDATE: TXT file after you have installed the new Netbeans

iMac with new ssd showing nothing but the pointer and white screen
Hello
I'm trying to fix an old imac (2008), 20 ", the mac crashed hard drive so I installed an SSD and tried to use the start switch to start on my yosemite bootable installation usb. When I try this, start pressing the option key, rather than see the start selector I see only a white screen with the black pointer. I tried to start another mac to this usb port, and it worked well. No one knows why this happens?
Thanks in advance,
Jasper
You are using a wired keyboard connected directly to the back of the iMac? If this isn't the case, you could try that.

When I subtract two numbers DBL and try to compare the result with another DBL, it fails
I found a curious problem with subtraction and compare numbers DBL in LabVIEW (8.6). Here's how it works:
1. subtract two numbers DBL such that the result is not incorporated. (Say, 3.2 - 3.1)
2. compare the result with a constant/control that is on the result of the subtraction (in the example, 0.1)
3 see the output of the comparison.
If the result of the subtraction is an integer, the Boolean result is (as expected). If the result is not complete, the comparison fails.
(Now, if I simply compare two floating point numbers, it works, so the issue is not with the node comparison itself, but with the data that is entered to the node). Can someone understand why this happens? It's unexpected, it's a pretty serious bug.
It is provided with all programming languages. Numbers do not have an exact binary floating-point representation. This has been discussed endlessly. Never use the equal function with floats. You can use the function in the range and force.
