Re: Use SQL to retrieve 2 numerical amounts and the difference between them from one field

Alan,

Just for the record, my (somewhat hastiliy contrived) solution was as
follows:
*********

CREATE VIEW TEMP/A_TEST01 AS
With T1 as (
SELECT A.*
, CAST(TRIM(
SUBSTR(FIELD1, LOCATE('xxxxxxxxxx', FIELD1) + LENGTH('xxxxxxxxxx') +1,
LOCATE('yyyyyyyyyy', FIELD1) - LENGTH('yyyyyyyyyy')- 2
)) AS Numeric(14, 2)) as Val1
, CAST(TRIM(
SUBSTR(FIELD1, LOCATE('yyyyyyyyyy', FIELD1) + LENGTH('yyyyyyyyyy') +1
)) AS Numeric(14, 2)) as Val2
FROM TEMP/FILEA A )
SELECT T1.*, VAL1-VAL2 AS DIF FROM T1
;
*********
