Simplest way in plain SQL would be individual case statements for each
column, I think.

SELECT pattern,
  CASE WHEN pattern LIKE 'foo%' THEN SUBSTR(pattern, 4) ELSE '' END AS foo
  CASE WHEN pattern LIKE 'bar%' THEN SUBSTR(pattern, 4) ELSE '' END AS bar
  CASE WHEN pattern LIKE 'baz%' THEN SUBSTR(pattern, 4) ELSE '' END AS baz
FROM tbl;
