Most efficient way to filter on two columns in WHERE clause? I need to check if a list of people's names are in our MySQL database.

SELECT * FROM tbltrainerinfo WHERE lastname = "Arpay"       AND firstname = "Belly Joy"
SELECT * FROM tbltrainerinfo WHERE lastname = "Bebelyn"     AND firstname = "Abulog"
SELECT * FROM tbltrainerinfo WHERE lastname = "Cabrera"     AND firstname = "Virgie"
SELECT * FROM tbltrainerinfo WHERE lastname = "Christopher" AND firstname = "Sajonia"
SELECT * FROM tbltrainerinfo WHERE lastname = "Edilberto"   AND firstname = "Galaura"
SELECT * FROM tbltrainerinfo WHERE lastname = "Embanecido"  AND firstname = "Efren"
SELECT * FROM tbltrainerinfo WHERE lastname = "Gertrulyn"   AND firstname = "Natonton"
SELECT * FROM tbltrainerinfo WHERE lastname = "Gina"        AND firstname = "Gindap"
SELECT * FROM tbltrainerinfo WHERE lastname = "Gindap"      AND firstname = "Gina"
SELECT * FROM tbltrainerinfo WHERE lastname = "Jeffrey"     AND firstname = "Ladiero"
SELECT * FROM tbltrainerinfo WHERE lastname = "JIMENEZ"     AND firstname = "JUNPORT"
SELECT * FROM tbltrainerinfo WHERE lastname = "Jocelyn"     AND firstname = "Paloma"
SELECT * FROM tbltrainerinfo WHERE lastname = "Ladera"      AND firstname = "Chared"
SELECT * FROM tbltrainerinfo WHERE lastname = "Lago"        AND firstname = "Michelle Joy"
SELECT * FROM tbltrainerinfo WHERE lastname = "Maratima"    AND firstname = "Untal"
SELECT * FROM tbltrainerinfo WHERE lastname = "Marciano"    AND firstname = "Iloreta"
SELECT * FROM tbltrainerinfo WHERE lastname = "Marianita"   AND firstname = "Gemina"
SELECT * FROM tbltrainerinfo WHERE lastname = "Pala"        AND firstname = "Sittie Norjanna"
SELECT * FROM tbltrainerinfo WHERE lastname = "Untal"       AND firstname = "Maratima"


How can I do one SELECT statement and get people's names if they are in the list?
Here is the FROM (VALUES... version, with an EXISTS thrown in to get some speedy search shortcuts happening:

SELECT *
FROM tbltrainerinfo
WHERE EXISTS(
    SELECT *
    FROM (VALUES
        ('Arpay','Belly Joy')
        ,('Bebelyn','Abulog')
        ,('Cabrera','Virgie')
        ,('Christopher','Sajonia')
        ,('Edilberto','Galaura')
        ,('Embanecido','Efren')
        ,('Gertrulyn','Natonton')
        ,('Gina','Gindap')
        ,('Gindap','Gina')
        ,('Jeffrey','Ladiero')
        ,('JIMENEZ','JUNPORT')
        ,('Jocelyn','Paloma')
        ,('Ladera','Chared')
        ,('Lago','Michelle Joy')
        ,('Maratima','Untal')
        ,('Marciano','Iloreta')
        ,('Marianita','Gemina')
        ,('Pala','Sittie Norjanna')
        ,('Untal','Maratima')
        ) AS List(LName, FName)
    WHERE LName = lastName
      AND FName = firstname
    )
