Query with Apostrophe (single quote)

Question

Hi all,
I have noticed that when you enter a search string with an apostrophe (eg. Tito's Station) in a textbox on a form linked to a table and hit the Query button, it generates an sql error. I think this is cos u cannot have an apostrophe (single quote) in the search string in a "where" clause.
I am using Portal version 3.0.6.6.5 on an 8.1.7 database.
I have logged a tar (1744105.999) for this but it is said to be a bug (1759202). I wish to enquire whether any of you have had this problem with a later version or at which version leve this bug has been fixed.
Does any1 know how to limit the text typed into a texbox, so that it wont accept certain characters (eg. the apostrophe key) ??
Thanks

Hi Rene'
Thanks for your help! This will definitely help me alot! I am a little baffled with your code for delimiting the single quote. I tried it and it doesnt work.
Thanks very much for the response

This is still an issue in 3.0.8.9.8. You can use a Javascript validation routine to disallow special characters.
If you want to check to see that they only enter certain things you can do:
var s = theElement.value;
var filter=/^[a-zA-Z]{1,}$/;
if (s.length == 0 ) return true;
if (filter.test(s))
return true;
else
alert(" Please input a valid character" );
theElement.focus();
theElement.select();
return false;
The above code would only allow one or more alphabetic characters. You could make it [a-zA-Z0-9] to allow alphanumeric characters. You could also allow anything but specific characters by doing the following:
var s = theElement.value;
var filter=/[^']*/;
if (s.length == 0 ) return true;
if (filter.test(s))
alert(" Please input a string without a single quote (') in it" );
theElement.focus();
theElement.select();
return false;
else
return true;
Hope this gets you started.
