Hi,
I'm looking for some way how to make strings with aggresive characters safe
for usement in SQL queries for Microsoft SQL - just something, what would
add slashes before such characters.
Is there any function for that?
Thanks. 2 1146
You can use;
str1 = str1.Replace("' ", "\'")
You can also change quotes to the HTML code for a quote like this;
str1 = str1.Replace("' ", "'")
When it gets sent to the screen it will appear as a '
Its hard to see but its taking single quote and replacing it with
\single quote. I use this all the time. I also have lots of data that
gets entered for web viewing only so I use the .Replace to change
VBCRLF's to <BR> so that the text appears exactly how it was entered in
the text box. Like this;
str1 = str.Replace(vbC rlf, "<br>")
Hope this helps,

No.
That's why ADO.NET has parameterized queries..so you don't have to worry
abou tit. using string replacements will eventually land you in trouble
'cuz someone's gonna figure out a unicode character string or something
that'll eventually circumvent it. Plus it's messy.
command.Command Text = "SELECT blah from Table where X = @x");
command.Paramet ers.Add("@X", SqlDbType.VarCh ar, 64).value = someVariable;
no need to do anything more...
Another advantage to this is it makes your code easily upgradable to
sprocs...or downgradable to inline queries.

Hello,
I can't figure out why my parameterized query from an ASP.NET page is
dropping "special" characters such as accented quotes & apostrophes, the

using .NET textbox web controls as well as html textareas. I have a test
