I am building up a string a storing them in the database:

eg:


72-8442

I was wondering how I would go about extracting '8442' from this string in SQL because I would like to do:

select serialnumber from assets where id = '8442'

Any ideas?

The Format is always:

ID1-ID2
72-8442

Cheers

if id1 is always 2 characters then....

select serialnumber from assets where substr(id,4) = '8442'

if id1 might vary in length then...

select serialnumber from assets where substr(id,instr(id,'-')+1) = '8442'


note, you won't be able to use an index on id when applying these conditions unless you create a function based index

Or if you don't know what the number will be, and assuming the column you're selecting is called myID:


select substring(myID, charindex('-',myID,1)+1, len(myID) )
