mattpick1 Spaces in phone number, String charAt()
Hi,
I am writing an Apex trigger which contains code to match a phone number to a contact phone number. It should match numbers that contain different spaces between the digits (when people store them they may store them in different formats).
First I thought of pulling out all the contacts in a query, then cyling through them using the trim() function on a string to match them. This seems wasteful though and there might be more contacts than the maximum number of records you are allowed to return.
So I then thought of creating a new string from the phone number I am matching with a '%' before and after each digit.
Eg. '07734654342' would become '%0%7%7%3%4%6%5%4%3%4%2%' then embedding that string in a query like:
//The phone string with the % chars is wildPhone Contact[] contact = SELECT Name FROM Contact WHERE Phone LIKE :wildPhone];
I'm not sure if this will work, but more importantly how do I go about creating that string? I thought there would be a charAt() method on the string like in Java...I can't find one though.
Thank you for your help.

String tamePhone;
tamePhone='111-222-3333'; //example
for (Integer i = 0; i < tamePhone.length; i++)
{
wildPhone += '%' + tamePhone.subString(i,1);
}
wildPhone += '%';

String tamePhone;
tamePhone='111-222-3333'; //example
for (Integer i = 0; i < tamePhone.length; i++)
{
wildPhone += '%' + tamePhone.subString(i,1);
}
wildPhone += '%';
Thanks! That looks like it will work, now to check that my wildcard plan will....
NB for the substring I think it should be tamePhone.substring(i, i+1), having an endIndex of 1 doesn't make sense to me unless the function was substring(startIndex, lengthOfSubstring) which I don't think it is.
Were you ever able to solve this issue?
