Subj:   Re: Extracting characters from a string
 
From:   Akshay.Munshi

Here's my suggestion:

select SUBSTR('FDB$H$03121622FDBPKG1_ETL', 1,
INDEX('FDB$H$03121622FDBPKG1_ETL', '$')-1)

select SUBSTR(SUBSTR('FDB$H$03121622FDBPKG1_ETL',
INDEX('FDB$H$03121622FDBPKG1_ETL', '$')+1), 1,
INDEX(SUBSTR('FDB$H$03121622FDBPKG1_ETL',
INDEX('FDB$H$03121622FDBPKG1_ETL',
'$')+1), '$')-1)


This way, if you have more or less number of characters before each $, you get them all. The only requirment is that the input string should have atleast 2 '$' signs. See below - I modified input string to include additional characters.

select SUBSTR('FDDBB$GGH$03121622FDBPKG1_ETL', 1,
INDEX('FDDBB$GGH$03121622FDBPKG1_ETL', '$')-1)

select SUBSTR(SUBSTR('FDDBB$GGH$03121622FDBPKG1_ETL',
INDEX('FDDBB$GGH$03121622FDBPKG1_ETL', '$')+1), 1,
INDEX(SUBSTR('FDDBB$GGH$03121622FDBPKG1_ETL',
INDEX('FDDBB$GGH$03121622FDBPKG1_ETL', '$')+1), '$')-1)
