Hello comunity
I have a table name field FT.DESCAR Varchar(60) with the following content:
5695 - 0 | 7050-127 MONTEMOR O NOVO
with this Select :
Select RIGHT(FT.DESCAR,CHARINDEX('|',FT.DESCAR)-1) from FT
where ftstamp = 'jm13070255373,181882981'
the result is:
OR O NOVO
to remove blank spaces i change my select to :
select RIGHT( Ltrim(Rtrim(FT.DESCAR)),CHARINDEX('|', Ltrim(Rtrim(FT.DESCAR)))-1) from ft where ftstamp = 'jm13070255373,181882981'
the result is the same:
OR O NOVO
I don´t understand why??
someone could give me some help.
Many thanks
Luis Santos

What are you trying to do? It seems to me that you want either one of these options.

Without sample data and expected results there's hard to know.

Select LEFT(FT.DESCAR,CHARINDEX('|',FT.DESCAR)-1) from FT

where ftstamp = 'jm13070255373,181882981'

Select RIGHT(FT.DESCAR,CHARINDEX('|',REVERSE(FT.DESCAR))-1) from FT

where ftstamp = 'jm13070255373,181882981'

You're on target Luis. It's a CHARINDEX and right command usage confusion.

OP, let's say you have this:

1234|1234567890

CHARINDEX (|) will = 5.

When you RIGHT(string,5) you get 67890.

What you need to do is RIGHT( string, LEN(string) - CHARINDEX()) to get to the correct # of characters, or use REVERSE() like Luis did above.

Just to share a trick for these "right splits"... you don't need the expense of a REVERSE.

Select SUBSTRING(FT.DESCAR,CHARINDEX('|',FT.DESCAR)+1,8000) from FT

where ftstamp = 'jm13070255373,181882981';

RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

Change is inevitable... Change for the better is not.

Hello comunity

First thanks for all of you for your replies.

I try this:

select substring('5695 - 0 | 7050-127 MONTEMOR O NOVO ',

charindex('|','5695 - 0 | 7050-127 MONTEMOR O NOVO ')+1 ,

len('5695 - 0 | 7050-127 MONTEMOR O NOVO ')) as [Last Name]

and sql query return the desire value:

7050-127 MONTEMOR O NOVO

Note: the value '5695 - 0 | 7050-127 MONTEMOR O NOVO ' is the content of my table field FT.DESCAR.

Best regards
