Have a look in Books Online regarding "String Functions". There's one there that does exactly what you want.

Select RIGHT('helloALL',3) will give 'ALL'.

you could try this, it's a bit crude but works...

declare @string varchar(50)

SET @string = 'ABCDEFGHIJ123'

select reverse ( substring ( reverse ( @string ) , 1 , 3 ) )

select substring ('ABC123',4,3)

select substring(srcString, charindex(targetString, SrcString),len(srcString)-charindex(targetString, SrcString)+1)

This is a generic statement to be used in place of Right() where srcString is the main string and targetString is the string to be found from srcString.

Just for fun - if RIGHT and CHARINDEX is prohibited but you are allowed to use a Tally table

DECLARE @txt VARCHAR(20)

SELECT @txt = 'helloALL'

SELECT

SUBSTRING(@txt, N, 1)

FROM Tally

WHERE N BETWEEN LEN(@txt) - 2 AND LEN(@txt)

FOR XML PATH('')

Hi,

I have a slightly similar problem

I hav a nvarchar field with no particular format of where spaces are

I want to split the string as below

<all chars-3> space <last 3 chars>

Eg: "ABCDEFG" should appear as "ABCD EFG"

"ABC DEFGH" should appear as "ABCDE FGH" etc

How can i do this using string functions. Pls help. Thanks

how about...

DECLARE @string VARCHAR(20)

SELECT @string = 'ABC DEFGH'

select @string = replace(@string,' ','')

select @string = substring ( @string, 1,(len(@string)-3)) + ' ' +

substring ( @string, (len(@string)-2),3 )

select @string

Does this help?

DECLARE @str NVARCHAR(10)

SET @str = 'ABCDEFGHI'

SELECT substring(@str, 1, len(@str) - 3) + ' ' + right(@str, 3)

Cheers,

Im stuck at another thing now

I have to do this conversion for all rows in the table

if i write select @string=str_col from tbl1

follwed by all the other string conversion statements;it gives me only the first row

How do i write the select command in the stored procedure statement to run for all rows in the table?

Well then, don't use the variable, it was only for the demo. Use your column name instead, and select it directly from your table.

Cheers,
