I have to write a query in Oracle. I have a table called 'Entity' with 2 columns 'Pref_mail_name' and 'spouse_name'.
Now i want list of all spouse_name where the last name of the spouse_name is not populated from pref_mail_name.
For example my table has following data
Pref_mail_name spouse_name
Kunio Tanaka | Lorraine
Mrs. Betty H. Williams | Chester Williams
Mr. John Baranger | Mrs. Cathy Baranger
William kane Gallio | Karen F. Gallio
Sangon Kim | Jungja
i need output as 1st and 5th row only. I did some analysis and came up with oracle built in function
SELECT PREF_MAIL_NAME, SPOUSE_NAME, UTL_MATCH.JARO_WINKLER_SIMILARITY(a, b)
similarity from entity
order by similarity;
But above query is not looking genuine.Even though spouse last name is not populated from pref_mail_name its giving a value above 80 for similarity.

I need to create column with name(s) (Supervisors - can be multiple supervisors at the same time, but also there might not be supervisor at all) from JSON format column, that not in 2 other column with names (Employee and Client).
Id
Employee
Client
AllParticipants
1
Justin Bieber
Ariana Grande
[{"ParticipantName":"Justin Bieber"},{"ParticipantName":"Ariana Grande"}]
2
Lionel Messi
Christiano Ronaldo
[{"ParticipantName":"Christiano Ronaldo"},{"ParticipantName":"Lionel Messi"}]
3
Nicolas Cage
Robert De Niro
[{"ParticipantName":"Robert De Niro"},{"ParticipantName":"Nicolas Cage"},{"ParticipantName":"Brad Pitt"}]
4
Harry Potter
Ron Weasley
[{"ParticipantName":"Ron Weasley"},{"ParticipantName":"Albus Dumbldor"},{"ParticipantName":"Harry Potter"},{"ParticipantName":"Lord Voldemort"}]
5
Tom Holland
Henry Cavill
[{"ParticipantName":"Henry Cavill"},{"ParticipantName":"Tom Holland"}]
6
Spider Man
Venom
[{"ParticipantName":"Venom"},{"ParticipantName":"Iron Man"},{"ParticipantName":"Superman"},{"ParticipantName":"Spider Man"}]
7
Andrew Garfield
Leonardo DiCaprio
[{"ParticipantName":"Tom Cruise"},{"ParticipantName":"Andrew Garfield"},{"ParticipantName":"Leonardo DiCaprio"}]
8
Dwayne Johnson
Jennifer Lawrence
[{"ParticipantName":"Jennifer Lawrence"},{"ParticipantName":"Dwayne Johnson"}]
The output column I need:
Supervisors
NULL
NULL
Brad Pitt
Albus Dumbldor, Lord Voldemort
NULL
Iron Man, Superman
Tom Cruise
NULL
I've tried to create extra columns to use Case expression after that, but it seems too complex.
SELECT *,
JSON_VALUE(w.AllParticipants,'$[0].ParticipantName') AS ParticipantName1,
JSON_VALUE(w.AllParticipants,'$[1].ParticipantName') AS ParticipantName2,
JSON_VALUE(w.AllParticipants,'$[2].ParticipantName') AS ParticipantName3,
JSON_VALUE(w.AllParticipants,'$[3].ParticipantName') AS ParticipantName4
FROM Work AS w
I'm wondering if there is an easy way to compare values and extract only unique ones.
I have tried to simplify my question with the following example:
I have a table with the following data:
Marker Name Location
1 Eric Benson Mixed
2 John Smith Rural
3 A David Rural
4 B John Mixed
And i want to insert into the table:
Name Location
Andy Jones Mixed
Ian Davies Rural
How can i continue the sequencein the Marker column to end up with:
Marker Name Location
1 Eric Benson Mixed
2 John Smith Rural
3 A David Rural
4 B John Mixed
5 Andy Jones Mixed
6 Ian Davies Rural
If you make this with a Stored Procedure you can ask the max of the Marker before to insert.
(That only works if the Marker Column is not identity)
Like This:
declare #max_marker int
set #max_marker=isnull((select max(marker) from table),0)
--Insert comes here
Insert into table (Marker,Name,Location) Values(#max_marker+1,'Andy Jones','Mixed')
how do i join following tables with wildcards? I would like to get all distinct rows from People table which contains SearchedName from SearchedPeople table.
SearchedPeople:
SearchedName
--------
Andrew
John
John Smith
People:
ID PersonName Attribute Age
----------------------------------------
1 John Smith 1 23
2 John Smith Jr 3 25
3 John Smith Jr II 4 73
4 Kevin 2 21
5 Andrew Smith 1 14
6 Marco 5 90
Desired Output:
PersonName Attribute Age
----------------------------------------
John Smith 1 23
John Smith Jr 3 25
John Smith Jr II 4 73
Andrew Smith 1 14
Code i got so far which doesnt wor. It returns three empty rows(why is that?).
SELECT b.PersonName, b.Attribute, b.Age
FROM SearchedPeople a
LEFT JOIN People b ON "%"&a.SearchedName&"%" like b.PersonName
It returns three empty rows because you don't have any columns from table a (SearchedPeople) and the LEFT JOIN didn't produce a match.
The reason is your criteria is in the wrong order you are searching for PersonName in the string %Searchedname% you need to switch that around. Also Access doesn't like the % as much as it likes the asteriks * for wilcard unless you make some changes to the query or configuration of MS-Access see below comment from Parafait.
I just tested this:
SELECT a.SearchedName
,b.PersonName, b.Attribute, b.Age
FROM
SearchedPeople a
LEFT JOIN People b
ON b.PersonName LIKE ("*" & a.SearchedName & "*")
Edit:
Good Ms Access specific information from a comment from #Parafait pasting in answer in case comment every got deleted.:
Use ALIKE and percents work. And if OP connects to MS Access via OLEDB and not the GUI .exe program, the % operator is required for LIKE statements in coded SQL. OP can also change database settings to ANSI-92 mode to always use % wildcards.
I have one table:
Person Name Country code
Andrew 1
Philip 2
John 1
Daniel 2
and a lookup table:
Country code Country name
1 USA
2 UK
I added them to powerpivot, created a relationship between the country code fields, then I created a pivot table. I expect to get the following:
Person Name Country code
Andrew USA
Philip UK
John USA
Daniel UK
But what I actually get is:
Person Name Country code
Andrew USA
Andrew UK
Philip USA
Philip UK
John USA
John UK
Daniel USA
Daniel UK
Couple of options:
Add a column to your main table that uses a formula to pull in the Country Name from your LookUp Table e.g.
=RELATED(LookUpTable[Country Name])
If you drag in any measure that references the main table you will get your desired result e.g. =COUNTROWS('MainTable') You then hide the results column if you had to.
I have this table
User | File | SubmittedDate
Joe 1223.txt 2011-11-12
Joe 3321.txt 2011-11-13
Jack 4332.txt 2012-11-22
Jane 2344.txt 2012-11-10
I want to select so I only get one record of Joe's, one of Jack's, and one of Jane's.
e.g.
Joe 1223.txt 2011-11-12
Jack 4332.txt 2012-11-22
Jane 2344.txt 2012-11-10
In other words, I want a result set of rows that has a unique user field. What's the SQL to get this?
A very quick Google search would show you there are several possible options:
https://www.google.com/search?client=safari&rls=en&q=select+unique+values+from+sql&ie=UTF-8&oe=UTF-8
One of which is to use the DISTINCT keyword:
SELECT DISTINCT User FROM ....
