尝试一下:
insert into table2
select name, lastname,
case language
when 'E' then 'English'
when 'S' then 'Spanish'
when 'F' then 'French'
else
'Unknown'
end
from table1

INSERT INTO table2 (name, lastname, language)
SELECT t1.name, t1.lastname,
CASE
WHEN t1.language = 'E' THEN 'English'
WHEN t1.language = 'S' THEN 'Spanish'
WHEN t1.language = 'F' THEN 'French'
END
FROM table1 t1
WHERE (t1.language = 'E' OR t1.language = 'S' OR t1.language = 'F')
