How can i do this in MS SQL 2016

Thanks on advance

Answer 1

You could try using left, right and charindex

 SELECT LEFT(your_col, charindex(' ', your_col) - 1) , 
       RIGHT(your_col, CHARINDEX (' ' ,REVERSE(your_col))-1)
from your_table

Answer 2

You can do the following.

First split string before the space separator

SUBSTRING(Nome, 0, CHARINDEX(' ', Nome))

Then split string at the last occurence

SUBSTRING( Nome , LEN(Nome) -  CHARINDEX(' ',REVERSE(Nome)) + 2  , LEN(Nome))

Concatenate both with the following + ' ' +

SELECT SUBSTRING(Nome, 0, CHARINDEX(' ', Nome)) + ' ' +
SUBSTRING( Nome , LEN(Nome) -  CHARINDEX(' ',REVERSE(Nome)) + 2  , LEN(Nome)  )
FROM table1;

Answer 3

Just in case other see this and needs SQL Server 2008 (or older).

You can modify the answer from scaisEdge to take care of single word-names, without using IIF (introduced in SQL Server 2012)

Simply add a space after name, when looking for first name, and add a space before name when looking for last name. replace co.Name with your actual column name.

LEFT(co.Name, charindex(' ', co.Name+' ') - 1) firstname, 
RIGHT(co.Name, CHARINDEX (' ' ,REVERSE(' ' + co.Name))-1) lastname,
