SQL - First and last name from full name - sql

Question

I have a field, in as SQL table, with the fullname of the users that shows the employee number and then the full name (20284 - JOAQUIM MIGUEL SAMPAIO PEREIRA)
I only want to show "JOAQUIM PEREIRA".
Right now am trying to use the following code:
SELECT left(NMSTRING, CHARINDEX(' ',NMSTRING,CHARINDEX(' ',NMSTRING,CHARINDEX(' ',NMSTRING)+1)+1)-1) +
substring(WFPROCATTRIB.NMSTRING, len(WFPROCATTRIB.NMSTRING)-CHARINDEX(' ', REVERSE(WFPROCATTRIB.NMSTRING))+1, len(WFPROCATTRIB.NMSTRING))
FROM WHATEVER
And the result i am getting is: "20284 - JOAQUIM PEREIRA"
How can i remove the "20284 - " part?

Answer 1

Try like this,
DECLARE #sql VARCHAR(50) = '20284 - JOAQUIM MIGUEL SAMPAIO PEREIRA'
SELECT substring(#sql, charindex('-', #sql) + 2, charindex(' ', substring(#sql, charindex('-', #sql) + 2, len(#sql)))) + ' ' + substring(#sql, LEN(#sql) - CHARINDEX(' ', REVERSE(#sql)) + 2, LEN(#sql))

Answer 2

If the employee number is always five characters, you could simply do:
select substring(NMString, 9, len(NMString))
Another method would be to use charindex():
select substring(NMString,
charindex(' - ', NMString) + 3,
len(NMString)
)

Answer 3

You can use substring to get the desired result
DECLARE #Name varchar(100) = '20284 - JOAQUIM PEREIRA'
SELECT SUBSTRING(#Name, CHARINDEX('-', #Name) + 1, LEN(#Name))
More examples:
DECLARE #TestTable TABLE
(
EmployeeDetails varchar(100)
)
INSERT INTO #TestTable VALUES ('20284 - JOAQUIM PEREIRA'),
('123 - Name1') , ('12312344 - Some Other Name')
SELECT SUBSTRING(EmployeeDetails, CHARINDEX('-', EmployeeDetails) + 1, LEN(EmployeeDetails)) FROM #TestTable

A little bit overkill, but should work for you:
--Declare table with example
DECLARE #WHATEVER TABLE (
NMSTRING nvarchar(max)
)
INSERT INTO #WHATEVER VALUES
(N'20284 - JOAQUIM MIGUEL SAMPAIO PEREIRA'),
(N'20285 - JOAQUIM SAMPAIO PEREIRA'),
(N'20286 - JOAQUIM PEREIRA')
--Declare xml variable
DECLARE #xml xml
--Put data in xml variable
SELECT #xml = (
SELECT CAST('<s><n>' + REPLACE(NMSTRING,' ','</n><n>') + '</n></s>' as xml)
FROM #WHATEVER
FOR XML PATH('')
)
The data in #xml will look like this:
<s>
<n>20284</n>
<n>-</n>
<n>JOAQUIM</n>
<n>MIGUEL</n>
<n>SAMPAIO</n>
<n>PEREIRA</n>
</s>
<s>
<n>20285</n>
<n>-</n>
<n>JOAQUIM</n>
<n>SAMPAIO</n>
<n>PEREIRA</n>
</s>
<s>
<n>20286</n>
<n>-</n>
<n>JOAQUIM</n>
<n>PEREIRA</n>
</s>
Then run this
SELECT t.v.value('n[3]','nvarchar(max)') + ' ' +
COALESCE(t.v.value('n[6]','nvarchar(max)'),t.v.value('n[5]','nvarchar(max)'),t.v.value('n[4]','nvarchar(max)'))
FROM #xml.nodes('/s') as t(v)
Output
JOAQUIM PEREIRA
JOAQUIM PEREIRA
JOAQUIM PEREIRA
