I have a text field and I want to get the data in the field after a certain character.

For example the column contains:

20070814~HCP*02*32*19.75*HEOS~LX*2~SV1*HC:97014:59*35.75*

I want to get what follows the characters 'HC', they will not always be in the same position in the field.

Can you tell me if this is possible and what I search on to find more info?

Thanks,
Marcie

select right(str, charindex('*HC:',str)+4,len(Str))
or maybe
select left(right(str, charindex('*HC:',str)+4,len(Str)), charindex('*',right(str, charindex('*HC:',str)+4,len(Str))-1)

Cursors are useful if you don't know sql.
DTS can be used in a similar way.

The right function does not work with a data type of text. Any other ideas? Thanks

how long is your string? If it might be longer than 8000 chars then you can't use charindex.

select substring(str, patindex('%*HC:%',str)+4,8000)
or maybe
select substring(substring(str, patindex('%*HC:%',str)+4,8000), charindex('*',substring(str, patindex('%*HC:%',str)+4,8000))-1)
