Question

I am running with one LIKE statement problem.
The situation is that:

1. I’m saving phone number and name associated with that number from the contact book to app’s db.

2. Then I am displaying this name in the uitableview by firing this query …

   NSString  *sqlTemp =[NSString stringWithFormat:@"select name from phoneData where number like %'%@'%",number1];
   

   number1 is (NSString *), the number I’m using is formatted like this (+international country code number). However number saved in db might be without country code and not prefixed with “+” symbol.

So my question is that even if number saved in the contacts book is not according to the international phone number, how can I ensure that it matches the other digits in the number?

Can any one suggest me some solution to this?

Here is what you can do:

NSRange range = NSMakeRange (3, [number1 length] - 3);
NSString *noPrefixNumber = [number1 substringWithRange:range];
NSString  *sqlTemp =[NSString  stringWithFormat:@"select name from phoneData where number like %'%@'%",noPrefixNumber ];
