Hapus digit/karakter numerik dari kolom string mysql

Solusinya adalah ini :( kelihatannya tidak bagus, tapi berhasil)

SELECT 
  TRIM(TRAILING '0' FROM 
    TRIM(TRAILING '1' FROM 
      TRIM(TRAILING '2' FROM 
        TRIM(TRAILING '3' FROM 
          -- ... 
            TRIM(TRAILING '8' FROM 
              TRIM(TRAILING '9' FROM name)))))) AS name
FROM your_table

Kemudian Anda dapat memilih dengan GROUP BY dari hasil:

SELECT name, count(*) AS frequency FROM (
-- previous select
) AS t
GROUP BY name
