たとえばselect count(*)、ある場所の範囲から別の場所へのステートメントが 10 個あります。

10 の位置範囲すべての合計を取得したいと思います。

SELECT count (*) 
FROM locn_hdr 
WHERE locn_brcd 
BETWEEN 'B2121' AND 'B2144'

SELECT count (*) 
FROM locn_hdr 
WHERE locn_brcd 
BETWEEN 'B2201' AND 'B2224'

mysql で次のクエリを試してください。

(sum(if('B2121' と 'B2144' の間の locn_brcd,1,0))+sum(if('B2201' と 'B2224' の間の locn_brcd,1,0))) を locn_hdr からの合計として選択します
