Split First Name Last Name Company- Split 1 Column to multiple

Name	Email
user Name1	xyz@abc.com
user Name2	xyz1@abc.com
User Name 3 (Company Inc)	xyz2@abc.com
Mr 123456 678	xyz3@abc.com
user Name4 123344 (Company Interactive 123)	xyz4@abc.com
Marcelle XYZ	xyz5@abc.com

Create a temp table and insert the data.

As you can see we may or may not have “braces” with company name.

Use the following code to split the first name, last name and company name.

--drop table temp
Create table temp (
id int identity(1,1)
,Name nvarchar(500)
,Email nvarchar(100)
)

insert into temp values ('user Name1','xyz4@abc.com'),('user Name4 123344 (Company Interactive 123)','xyz4@abc.com')

select * from temp

alter table temp
add
FirstName nvarchar(100),LastName nvarchar(100),Company nvarchar(100)

DECLARE
@Id int
,@Name nvarchar(1000)
,@FirstName nvarchar(100)
,@LastName nvarchar(100)
,@Company nvarchar(100)
,@sDelimiter nVARCHAR(100)

DECLARE vendor_cursor CURSOR FOR
select Id, Name from temp

OPEN vendor_cursor

FETCH NEXT FROM vendor_cursor
INTO @Id, @Name

WHILE @@FETCH_STATUS = 0
BEGIN

select @FirstName = ''
,@LastName = ''
,@Company = ''

SET @sDelimiter = ' '
 IF CHARINDEX(@sDelimiter,@Name,0) <> 0
 BEGIN
 SELECT @FirstName = RTRIM(LTRIM(SUBSTRING(@Name,1,CHARINDEX(@sDelimiter,@Name,0)-1))),
 @Name = RTRIM(LTRIM(SUBSTRING(@Name,CHARINDEX(@sDelimiter,@Name,0)+LEN(@sDelimiter),LEN(@Name))))
 END

SET @sDelimiter = '('
 IF CHARINDEX(@sDelimiter,@Name,0) <> 0
 BEGIN
 SET @LastName = RTRIM(LTRIM(SUBSTRING(@Name,1,CHARINDEX(@sDelimiter,@Name,0)-1)))
 set @Company = REPLACE (RTRIM(LTRIM(SUBSTRING(@Name,CHARINDEX(@sDelimiter,@Name,0)+LEN(@sDelimiter),LEN(@Name)))),')','')
 END
 ELSE
 SET @LastName = substring(@Name,charindex(' ', @Name)+1,len(@Name))

update temp
 set
 FirstName = @FirstName
 ,LastName = @LastName
 ,Company = @Company
 where
 Id = @Id

FETCH NEXT FROM vendor_cursor
INTO @Id, @Name
END
CLOSE vendor_cursor
DEALLOCATE vendor_cursor

Finally, your temp table will have the separated columns.
