Check this out:

select fullname, left(fullname,patindex('%[A-Z,a-z][ |.]%',fullname)+3)              as firstName, 
                 Right(fullname,len(fullname)-patindex('%[A-Z,a-z] %',fullname)-3) as LastName   from YOUR_TABLE

NOTE:

This script expects names like:
Anthony N. lampoon
OR
Anthony N lampoon

This link will offer some insight.  As will this one.  Also this one.  These all rely on finding the first or last space in the column.

This will be almost impossible to do correctly, however.  Oscar de la Renta - whose first name is "Oscar" and last name is "de la Renta", will end up like "Oscar de la" and "Renta".  This gets worse if the name includes a middle name and/or a suffix (such as Jr or Sr).

you can also use this:


select left(fullname,patindex('%.%',fullname)) as firstName, Right(fullname,len(fullname)-patindex('%.%',fullname)) as LastName from YOUR_TABLE

Open in new window


assume fullname has concatenated names and always there is a "." exists in this field.

Some of the name have a "." and other do not. A few example of the names I have to contend with

Sam R. Willow III
Sam R. Willow

Results required:

Sam R.  firstname
Willow III lastname

Sam R. firstname
Willow lastname

Too bad it wasn't set up properly in the first place 4 fields

pseudocode
firstname, middleinit, lastname, suffix
full_name = firstname 
if middleinit -ne NULL {  fullname = fullname + " " + middleinit
}
fullname = fullname + " " + lastname
if (suffix -ne NULL) {fullname = fullname + " " + Suffix}
return fullname;

The example you give of "Sam R. Willow III"   ( and other titles that may appear after the surname, like "Jr" ), and the previous example of "de laRenta"  demonstrates that you're probably not going to be able to automate this 100%.

So, use some of he suggestions above to get most of the way there, then check manually.

How many names ? If not enormous, you may be able to do some useful work by importing to Excel, using the Text to Columns function, and then picking out the 'diffficult cases' which will often ( but not always) be the ones that have 4 part names - so the 4th column in Excel will get a value. Identify them, then fix them manually.

It is a waste of time to have a bad data entry formats and then try to develop routines to organize it.
.
I suggest you manually clean the data to fit the fname i. lname.

Later, write the validation rules to acquire data in proper format.
