I have source file with column
Full Name
Jim k Smith
Robert K Lin
Chris Tim
and My destination has
FirstName and LastName
I want to parse FullName
I know how I can use SSIS Expression to parse the address, Here it is
FirstName = LTRIM(RTRIM(TRIM(REVERSE(SUBSTRING(REVERSE([Full Name]),1,FINDSTRING(REVERSE([Full Name])," ",1))))))
LastName = LTRIM(RTRIM(TRIM(SUBSTRING([Full Name],1,FINDSTRING([Full Name]," ",1)))))
Is any one can help me to transfer in T-SQL?
Thank You in advance.

You need to realize that you might have names that can change the logic. The most common example would be spanish names (which can appear even in an English speaking country).

However, for the examples you posted, here's an option. Check out that the CTE is just to work with the sample data. Please post it in a consumable format next time.

WITH CTE AS(

SELECT 'Jim k Smith' [FullName] UNION ALL

SELECT 'Robert K Lin' UNION ALL

SELECT 'Chris Tim'

)

SELECT LEFT( FullName, LEN(FullName) - CHARINDEX( ' ', REVERSE(FullName))),

RIGHT( FullName, CHARINDEX( ' ', REVERSE(FullName)) - 1)

FROM CTE

I think this is a slightly shorter solution.

LastName = reverse(left(reverse(FullName), charindex(' ', reverse(FullName)) - 1))

Thank You For your help...

However I want only FirstName and LastName

the logic would be for FirstName = From Left to ' ' (First Space)

the logic would be for LastName = From Rifh to ' ' (First Space)

Please advise...

I think this is a slightly shorter solution.
LastName = reverse(left(reverse(FullName), charindex(' ', reverse(FullName)) - 1))

How is that shorter and why do you believe that 3 REVERSEs are better than 1?

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.

Then it's a lot easier.

WITH CTE AS(

SELECT 'Jim k Smith' [FullName] UNION ALL

SELECT 'Robert K Lin' UNION ALL

SELECT 'Chris Tim'

)

SELECT LEFT( FullName, CHARINDEX( ' ', FullName)),

RIGHT( FullName, CHARINDEX( ' ', REVERSE(FullName)))

FROM CTE

Awesome,

That's what I want...

Thank You!

Jeff,

I was mistaken because I looked too quickly over the code and didn't read it properly. My code was neither shorter nor simpler.

I am appropriately abashed.

HI Luis, I am a newbie and I have a doubt on your code.

What is the purpose of the REVERSE() in your code?

ie. here... REVERSE(FullName)

Luis Cazares SSC Guru Points: 183706 More actions · Answer 9

Hi George,

You should really be trying to figure out this yourself by using BooksOnLine (BOL or SQL Server help) but I'll try to explain.

REVERSE will do exactly what it says, returns the reverse order of a string value.

I use it because I need to find the last space in the string. As CHARINDEX won't have a backwards function, I need to reverse the string to get the last space that will become the first one. Was I clear or did I confuse you even more? 😛

No problem. I thought I was missing something. Thank you for the feedback.

To add to that, especially since George is a newbie...

@george, just in case you don't know (a lot of newbies don't), "Books Online" is the "help" documentation that comes with SQL Server. You can easily get there by pressing the {f1} key from SSMS (SQL Server Management Studio).
