SUBSTRING

[robertrao]

Hello,

Here below I have a column called EMAIL

Of all the emails we wanted to check how many times gmail was wrongly entered....

Since GMAIL starts with the letter "G" we can take all the words starting with letter G after @ in the email adress??????

HAVE:

[email protected]

[email protected]

[email protected]

[email protected]

elephant@gmail.con

goat@yahoo.com

horse@hotmail.com

[email protected]

[email protected]

WANT:

gmail.com    2

gunail.com   1

GMAI.COM   1

gmail.con      1

gnail.com      1

gmi.com       1

Combine scan and substr functions.

I will suggest that limiting your search to @g is insufficient. You may well have enteries like [email protected] or [email protected] or ...

I might be tempted to do something like:

data have;
   length email $40.;
   input email;
   isp =upcase(scan(email,2,"@"));
   distance = complev('gmail.com',isp,'i');
datalines;
[email protected]
[email protected]
[email protected]
[email protected]
[email protected]
[email protected]
[email protected]
[email protected]
[email protected]
[email protected]
[email protected]
;

proc tabulate data=have;
   class distance isp;
   table distance*isp,n;
run;

The "distance" value when small means the spelling is "close" to Gmail.com.

Note that I did add in couple of other possibly typos.
