SQL: Is it possible to 'group by' according to 'like' function's results?

Question

I am using Oracle SQL and I want to group some different rows that \'like\' function results. To elaborate with an example:

Let\'s assume I have a table MESA w

Answer 1

I would do it this way -- only requires a single change to add additional types of fruit.

WITH fruits AS (
  SELECT 'APPLE' fruit FROM DUAL
  UNION ALL
  SELECT 'ORANGE' fruit FROM DUAL
)
SELECT fruit, count(*)
FROM MESA m, fruits
WHERE m.str LIKE '%FRUIT%'
AND m.str LIKE '%' || fruits.fruit || '%'
GROUP BY fruit

If your strings are reliably in the format you showed in your sample data, I would consider changing the predicate to one condition, WHERE m.str LIKE 'FRUIT%' || fruits.fruit ||'%'.
