i am having long string in column as a full name of the employee , i want to break that down in first name, middle name and last name. for example i am having Andrade, Maria Sandra (lname,(space)fname(space)mname)breaking will be like
fname =Maria, lname= Andrade and middle name like Sandra.
My column generally have lname,fname.
i am able to divide lname, but not correct breaking for fname and mname
SELECT EmployeeName as [full name ], SUBSTRING( EmployeeName,CHARINDEX(',',EmployeeName)+1,LEN(EmployeeName)) as[First name ]
,SUBSTRING( EmployeeName,0,CHARINDEX(',',EmployeeName)) [Last Name]
, SUBSTRING( SUBSTRING( EmployeeName,CHARINDEX(',',EmployeeName)+1,LEN(EmployeeName)),CHARINDEX(' ',EmployeeName),LEN (SUBSTRING( EmployeeName,CHARINDEX(',',EmployeeName),LEN(EmployeeName)))) as[Middle name ]
FROM test$`
Here's a perfect reason why you should normalize your data.
declare #table table(thename varchar(500))
insert into #table
values
('Andrade, Maria Sandra'),
('Andrade, Maria'),
('Andrade, Maria Sandra OhSnap')
select
left(thename,CHARINDEX(',',thename) - 1) as LastName
,substring(thename,charindex(' ',thename),case when charindex(' ',thename) + charindex(' ',reverse(thename)) > len(thename) then charindex(' ',reverse(thename)) else len(thename) - (charindex(' ',thename) + charindex(' ',reverse(thename))) + 1 end) as FirstName
,case when charindex(' ',thename) + charindex(' ',reverse(thename)) - 1 = len(thename) then null else right(thename,charindex(' ',reverse(thename))) end as MiddleName
from #table

My 'name' column has names stored like this
Lastname Firstname Middlename
I want to display it like this in my query:
Firstname Middlename Lastname
Not all records have a middle name, so they may be 1 or 2 spaces in the column
I have tried this :
SELECT CONCAT ( SUBSTRING_INDEX(`name`, ' ', 1) , ' ' , SUBSTRING_INDEX(`name`, ' ', -1) ) AS nicename`
But this only gives the last name. The "-1" part is not working...
Thanks for all help.
To start with, that's a bad design, Now, since your middlename part may be empty, you may bear with it and just select the name saying select name from tbl1.
Else, consider re-designing your table to have separate columns for Lastname, Firstname and Middlename and then You don't need all of this. You can just get data from all 3 columns saying
select concat(Firstname, Middlename, Lastname ) as nicename
from tbl1;
Found a solution :
SELECT concat ( TRIM( SUBSTR(`name`, LOCATE(' ', `name`)) ), ' ', SUBSTRING_INDEX(SUBSTRING_INDEX(`name`, ' ', 1), ' ', -1) ) as nicename
Source: How to split the name string in mysql?
In SQL Server, I have a column NAME with data like this:
1, CHAN Tai Man
2, CHAN Ting Ting
I would like to have a query that extract the NAME2 to
1, CHAN T M
2, CHAN T T
As you may observe that only initial of the given name is required. How can I achieve that in SQL Server 2008? Many thanks for your gentle help.
Like Gordon said,the first one is easy and here's my take on it
DECLARE #table TABLE(id INT,name nvarchar(50))
Insert into #table
Values(1,'CHAN Tai Man')
Insert into #table
Values(2, 'CHAN Ting Ting')
select name
, LEFT(name, (PATINDEX('%[ _-]%',name))) +substring(name,(PATINDEX('%[ _-]%',name)+1),1) +' '+substring(reverse(rtrim(substring(reverse(name), 1, charindex(' ', reverse(name))))),(PATINDEX('%[ _-]%',reverse(rtrim(substring(reverse(name), 1, charindex(' ', reverse(name))))))+1),1) as Fullname
from #table
The first initial is pretty easy:
select left(name, charindex(' ', name) + 1)
The second is a bit tougher. I think the logic is like this
select (left(name, charindex(' ', name) + 1) +
substring(reverse(name), charindex(' ', reverse(name)) - 1, 1)
)
You might need to include case statements to be sure that the name has two spaces.
I'm trying to split a name column (fullname) with the format lastname, firstname into two separate columns in MySQL using:
SELECT SUBSTRING_INDEX(SUBSTRING_INDEX(fullname, ',', 1), ' ', -1) as firstname, SUBSTRING_INDEX(SUBSTRING_INDEX(fullname, ',', 2), ' ', -1) as lastname FROM tablename;
This works on most names. However, a name like "Del Torres Jr, Marcelo" shows up as
--------------------
lastname | firstname
--------------------
JR | Marcelo
--------------------
How to I need to alter my statement to capture all of a name after the comma?
Can you not just use:
SELECT SUBSTRING_INDEX(fullname, ',', 1) AS firstname
,SUBSTRING_INDEX(fullname, ',', -1) AS lastname
FROM table
SQLFiddle
I can't tell what you're trying to do with the match against ' ' but if you're just trying to trim whitespace you can use TRIM() on those values.
is this what you want ?
SELECT
SUBSTRING_INDEX(value, ' ,', 1) as lastname ,
SUBSTRING_INDEX(value, ' ,', -1) as firstname
FROM event;
demo
and in your query you should change -1 to 1 like that
SELECT SUBSTRING_INDEX(SUBSTRING_INDEX(fullname,',', 1),' ', -1) as firstname,
SUBSTRING_INDEX(SUBSTRING_INDEX(fullname,',', 2),' ', 1) as lastname
^--this should be 1
FROM tablename;
Currently I'm working on a database redesign project. A large bulk of this project is pulling data from the old database and importing it into the new one.
One of the columns in a table from the old database is called 'name'. It contains a forename and a surname all in one field (ugh). The new table has two columns; forenames and surname. I need to come up with a clean, efficient way to split this single column into two.
For now I'd like to do everything in the same table and then I can easily transfer it across.
3 columns:
Name (the forename and surname)
Forename (currently empty, first half of name should go here)
Surname (currently empty, second half of name should go here)
What I need to do: Split name in half and place into forename and surname
If anyone could shed some light on how to do this kind of thing I would really appreciate it as I haven't done anything like this in SQL before.
Database engine: MySQL
Storage engine: InnoDB
A quick solution is to use SUBSTRING_INDEX to get everything at the left of the first space, and everything past the first space:
UPDATE tablename
SET
Forename = SUBSTRING_INDEX(Name, ' ', 1),
Surname = SUBSTRING_INDEX(Name, ' ', -1)
Please see fiddle here. It is not perfect, as a name could have multiple spaces, but it can be a good query to start with and it works for most names.
Try this:
insert into new_table (forename, lastName, ...)
select
substring_index(name, ' ', 1),
substring(name from instr(name, ' ') + 1),
...
from old_table
This assumes the first word is the forename, and the rest the is lastname, which correctly handles multi-word last names like "John De Lacey"
For the people who wants to handle fullname: John -> firstname: John, lastname: null
SELECT
if( INSTR(`name`, ' ')=0,
TRIM(SUBSTRING(`name`, INSTR(`name`, ' ')+1)),
TRIM(SUBSTRING(`name`, 1, INSTR(`name`, ' ')-1)) ) first_name,
if( INSTR(`name`, ' ')=0,
null,
TRIM(SUBSTRING(`name`, INSTR(`name`, ' ')+1)) ) last_name
It works fine with John Doe. However if user just fill in John with no last name, SUBSTRING(name, INSTR(name, ' ')+1)) as lastname will return John instead of null and firstname will be null with SUBSTRING(name, 1, INSTR(name, ' ')-1).
In my case I added if condition check to correctly determine lastname and trim to prevent multiple spaces between them.
This improves upon the answer given, consider entry like this "Jack Smith Smithson", if you need just first and last name, and you want first name to be "Jack Smith" and last name "Smithson", then you need query like this:
-- MySQL
SELECT
SUBSTR(full_name, 1, length(full_name) - length(SUBSTRING_INDEX(full_name, ' ', -1)) - 1) as first_name,
SUBSTRING_INDEX(full_name, ' ', -1) as last_name
FROM yourtable
Just wanted to share my solution. It also works with middle names. The middle name will be added to the first name.
SELECT
TRIM(SUBSTRING(name,1, LENGTH(name)- LENGTH(SUBSTRING_INDEX(name, ' ', -1)))) AS firstname,
SUBSTRING_INDEX(name, ' ', -1) AS lastname
I had a similar problem but with Names containing multiple names, eg. "FirstName MiddleNames LastName" and it should be "MiddleNames" and not "MiddleName".
So I used a combo of substring() and reverse() to solve my problem:
select
SystemUser.Email,
SystemUser.Name,
Substring(SystemUser.Name, 1, instr(SystemUser.Name, ' ')) as 'First Name',
reverse(Substring(reverse(SystemUser.Name), 1, instr(reverse(SystemUser.Name), ' '))) as 'Last Name',
I do not need the "MiddleNames" part and maybe this is not the most efficient way to solve it, but it works for me.
Got here from google, and came up with a slightly different solution that does handle names with more than two parts (up to 5 name parts, as would be created by space character). This sets the last_name column to everything to the right of the 'first name' (first space), it also sets full_name to the first name part. Perhaps backup your DB before running this :-) but here it is it worked for me:
UPDATE users SET
name_last =
CASE
WHEN LENGTH(SUBSTRING_INDEX(full_name, ' ', 1)) = LENGTH(full_name) THEN ''
WHEN LENGTH(SUBSTRING_INDEX(full_name, ' ', 2)) = LENGTH(full_name) THEN SUBSTRING_INDEX(del_name, ' ', -1)
WHEN LENGTH(SUBSTRING_INDEX(full_name, ' ', 3)) = LENGTH(full_name) THEN SUBSTRING_INDEX(del_name, ' ', -2)
WHEN LENGTH(SUBSTRING_INDEX(full_name, ' ', 4)) = LENGTH(full_name) THEN SUBSTRING_INDEX(del_name, ' ', -3)
WHEN LENGTH(SUBSTRING_INDEX(full_name, ' ', 5)) = LENGTH(full_name) THEN SUBSTRING_INDEX(del_name, ' ', -4)
WHEN LENGTH(SUBSTRING_INDEX(full_name, ' ', 6)) = LENGTH(full_name) THEN SUBSTRING_INDEX(del_name, ' ', -5)
ELSE ''
END,
full_name = SUBSTRING_INDEX(full_name, ' ', 1)
WHERE LENGTH(name_last) = 0 or LENGTH(name_last) is null or name_last = ''
SUBSTRING_INDEX didn't work for me in SQL 2018, so I used this:
declare #fullName varchar(50) = 'First Last1 Last2'
declare #first varchar(50)
declare #last varchar(50)
select #last = right(#fullName, len(#fullName)-charindex(' ',#fullName, 1)), #first = left(#fullName, (charindex(' ', #fullName, 1))-1);
Yields #first = 'First', #last = 'Last1 Last2'
I have a field name with the following rows:
`name`
------
John Smith
George Washington
Ash Ketchum
Bill O'Reilly
I would like to reformat the rows on output:
`name`
------
SMITH, JOHN
WASHINGTON, GEORGE
KETCHUM, ASH
O'REILLY BILL
I know I can use upper( x.name ) for casing, but how can I reformat the names?
Assuming your rdbms is mySql, answer will need to be tailored to differenct dialects of sql.
SELECT concat( substring(name, locate(name, ' ')), ', ', substring(name, 0, locate(name, ' ') - 1)) FROM NAMES;
The real problem here however is data integrity. You need to have seperate columns for each peice of the name so that formating in the database is ensured to be consitent. Ideally you would want to be doing this --
Select concat(last_name, ', ', first_name) FROM NAMES;
Allowing
'name'
-------------------
John Smith
Smith, John
J Smith
Smith J
John q Smith
Jhon 'the smithmeister' Smith
All in the same column of a table is a bad thing for a number of reasons so this should be explictly prevented.
Try this:
SELECT SUBSTRING_INDEX( `name` , ' ', -1 ) + ', ' + SUBSTRING_INDEX( `name` , ' ', 1 )
FROM MyTable
#Ben, makes a good point about names with multiple spaces in them. I doubt this would give you the output you want in those cases, but it should get you started.
try this
SELECT Concat(SUBSTRING_INDEX( `name` , ' ', -1 ) , ', ' , SUBSTRING_INDEX( `name` , ' ', 1 )) as name
FROM your_Table
