: Operator in VB.NET [duplicate] - vb.net

This question already has answers here:
'If' statement and the colon

Closed 8 years ago.
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.

SQL not accepting my string as a condition in a CASE statement [duplicate]

How do I escape a single quote in SQL Server?
(14 answers)
Closed 8 months ago.
I am using SQL Server and SSMS.
I am writing a CASE expression in SQL. Here is one of the lines
WHEN [Group] = 'Representation Accepted' AND [Reason] = 'Reduced to Warning Notice' Area Authorised' THEN 31
The issue I am having here is that for the string:
Reduced to Warning Notice' Area Authorised
SQL is getting confused with the quotation mark here and believes it to be the end of the condition and completely omits " Area Authorised". I'm not sure how to solve this issue without removing the single quotation mark. Does anyone know how I cam make SQL accept the entire string with the quotation mark as a condition?.
use two times single quotation as below
WHEN [Group] = 'Representation Accepted' AND [Reason] = 'Reduced to Warning Notice'' Area Authorised' THEN 31

In C# I can do this:

If (success) Then

Else
outcome = "failed"
End If
outcome = If(success,"succeeded","failed")
