How to write ternary conditional operator?
(33 answers)

What is the equivalent of this expression in Kotlin.
a ? b : c
This is giving error.
In Kotlin, if statements are expressions. So the following code is equivalent:
if (a) b else c
Hope it's working for you.

Oracle equivalent of Java's Varargs
(2 answers)
Closed 3 years ago.
Can a function in Oracle have an unknown number of parameters?
for example: create function sample(parameters... varchar)
so it can call something like: sample("A") or sample("A","B") or sample("A","B","C")
You can use sys.odcivarchar2list:
function sample(parameters sys.odcivarchar2list)
And then call it by:
sample(sys.odcivarchar2list('A','B','C'))
or
sample(sys.odcivarchar2list('A'))
and so on.

Is there a conditional ternary operator in VB.NET?
(5 answers)
Closed 4 years ago.
In C# I can do this:
string outcome = (success?"succeeded":"failed")
But in VB.NET is this syntax the only equivalent operation?:
If (success) Then
outcome = "succeeded"
Else
outcome = "failed"
End If
outcome = If(success,"succeeded","failed")

Should I use != or <> for not equal in T-SQL?
(14 answers)
Closed 6 years ago.
Using SQL Server 2008 I have a query which resembles this:
SELECT *
FROM myTable mt
WHERE mt.ID !=0
What is the !=0 ? It looks like it's the same as saying <> 0.
I am unable to google this, is this in fact the same? A link to some documentation would be appreciated.
It is exactly the same operator as <>.
See MSDN for reference.
This is the C convention for "not equal". There is another C convention for "equal" that looks like ==.

Like
The LIKE operator is used to search for a specified pattern in a column.
Where
The WHERE clause is used to extract only those records that fulfill a specified criterion.
In your case the first query do not work is because no records match the criteria you are searching.

'If' statement and the colon

What this code mean in VB.NET ?
I don't understand with : operator.
Is it same with ternary operator in Java/C#/C ?
If InStr(elementName, "*") > 0 And depth < maxDepth Then isRule = True : isGrRule = True
In VB.NET, colon : is used to put two statements in one line and acts as a separator for those statements.
See more on MSDN:
To place multiple statements on the same line
Separate the statements with a colon (:), as in the following example.
text1.Text = "Hello" : text1.BackColor = System.Drawing.Color.Red
It has nothing to do with the ternary operator in Java/C#/C.
