I need to create a function to select just 3 octets from a column (ip_number). I paste below the select that I did, but it is very large. anyone have any idea so that I can reduce this select?
 I want to identify only three octets, the IP number
declare @x varchar(20) select @x = '10.0.42.162' select @x = '10.0.200.120'
select @x Ip, substring(@x,1,len(substring(@x,1,charindex('.', @x ))))+ substring(substring(@x,len(substring(@x,1,len(substring(@x,1,charindex('.', @x )))))+1,len(@x)),1, len(substring(substring(@x,len(substring(@x,1,len(substring(@x,1,charindex('.', @x )))))+1,len(@x)),1, charindex('.', substring(@x,len(substring(@x,1,len(substring(@x,1,charindex('.', @x )))))+1,len(@x)) )))) + substring(SUBSTRING(@x,len(substring(@x,1,len(substring(@x,1,charindex('.', @x ))))+ substring(substring(@x,len(substring(@x,1,len(substring(@x,1,charindex('.', @x )))))+1,len(@x)),1, len(substring(substring(@x,len(substring(@x,1,len(substring(@x,1,charindex('.', @x )))))+1,len(@x)),1, charindex('.', substring(@x,len(substring(@x,1,len(substring(@x,1,charindex('.', @x )))))+1,len(@x)) )))))+1, LEN(@x)),1,charindex('.', SUBSTRING(@x,len(substring(@x,1,len(substring(@x,1,charindex('.', @x ))))+ substring(substring(@x,len(substring(@x,1,len(substring(@x,1,charindex('.', @x )))))+1,len(@x)),1, len(substring(substring(@x,len(substring(@x,1,len(substring(@x,1,charindex('.', @x )))))+1,len(@x)),1, charindex('.', substring(@x,len(substring(@x,1,len(substring(@x,1,charindex('.', @x )))))+1,len(@x)) )))))+1, LEN(@x)) )) rede

DECLARE @t VARCHAR(15)
SET @t = '111.222.333.444'
SELECT PARSENAME(@t,4),PARSENAME(@t,3),PARSENAME(@t,2)
