Oracle NVL Look for Certain Value else blank Equivalent in Mysql

In Oracle, I can have in the criteria:

test_table.id = email_table.id (+)


If the test_table.id and email_table.id is the same and the email_table.primary_email='Y' then have 'Y' else '' in the email_table.primary_email results so example:

test_table.id email_table.id email_table.primary_email
1 1 Y
2 NO 2 in table blank
3 3 blank (IDs in both tables but email_table.primary_email='N' so blank)

Is there a way to do this in Mysql?

Help is very appreciated!
