it's only about ( SINGLE QUOTATION) in ASP.NET

here is my SQL Query:

SELECT ID, Title
FROM viewTopTitles
WHERE Title = ' you're most welcome '



but duo to the SINGLE QUOTATION I have a fatal Error, I tried to use function like this:

WHERE  REPLACE("you're most welcome", " ' ", " ' ' ")

...

Error I get with this is :
Msg 4145, Level 15, State 1, Line 3
An expression of non-boolean type specified in a context where a condition is expected, near ')'.

and thene tried like this :

WHERE  Title = REPLACE("you're most welcome", " ' ", " ' ' ")...



Error I get with this is :
Msg 207, Level 16, State 1, Line 3



IS THERE ANY BODY CAN GIVE ME A FULL EX. OF THE QUERY, OR TELLS ME HOW APPROPRIATE SHOULD I'VE TO USE THIS;

THANK YOU

PS: I AM KINDDA NEW TO THIS Ermm

thanks imex

but it would work in Query Engine in SQL Server but as in my case am in ASP.NET and can't fix with this all the links (Titles) that contain SINGLE QUOTATIONS


so how could I avoid the error dynamically ????? Ermm

I found it :-)

here is the solution



public string mySTRING (string singleQ){
return singleQ.Replace(" ' ", " ' ' ");
}




SELECT ID, Title
FROM viewTopTitles
WHERE Title = mySTRING (you're most welcome)

If you run that result query you posted, I'm pretty sure you'll find that it doesn't actually work. The single quote needs to have two single quotes and the whole string literal needs to be wrapped in single quotes.

RBAR is pronounced ree-bar and is a Modenism for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
     Stop thinking about what you want to do to a row... think, instead, of what you want to do to a column.
Although they tell us that they want it real bad, our primary goal is to ensure that we dont actually give it to them that way.
Although change is inevitable, change for the better is usually not.
Just because you can do something in PowerShell, doesnt mean you should. Wink

you're right, it's just that I didn't mentioned or write it in here, but I did wrap it with a single quotation to the whole string :-)

thank you :-)

Or for an even better approach don't use pass through sql from your .NET app. Instead use parameters. From the issues you are facing it is very likely that your application is vulnerable to sql injection.
