How to keep only required email address 

example here keep only gmail.com address

[SASKiwi]

data email;
input email $30.;
email_provider = scan(email, 2, '@');
datalines;
xxxxxxxxxxx@gmail.com
xxxxxxxxxxxx@outlook.com
xxxxxxxxxxx@gmail.com
xxxxxxxxxxx@gmail.com
;
run;

There are many ways to do this including the SCAN function to read the second word in the string where an ampersand is the delimiter.

i want output those who have gmail email address in this example data contains three gmail address 

i want complete three gmail address

[Kurt_Bremser]

Just use the SCAN function with "@" as delimiter to get the domain from the email address; if the result of the function is found to be "gmail.com", keep the observation. Can be done in a WHERE statement, WHERE= dataset option, or Subsetting IF, depending on where the subsetting needs to be done.

I will not insult your intelligence by providing this EXTREMELY SIMPLE code. If you cannot solve such a simple issue by now (500+ posts here), then drop your illusion that you'll ever earn money with SAS work.
