I want to achieve is to search for a full name in a database with only a string with his first and last name.
in database there is the full name:
Manuel Augusto Vieira Conde Fialho
and I want a sql query that can search this full name only with the first and last name :
Manuel Fialho
I've tried this one:
SELECT name FROM partners WHERE name LIKE 'Manuel Fialho'";
but this does not work for me because I don't have any Manuel Fialho in the database only a Manuel Augusto Vieira Conde Fialho and because of that the name im looking for does not show.
thank you
You shoould add %:
SELECT name FROM partners WHERE name LIKE 'Manuel%Fialho';
One method uses wildcards:
SELECT name
FROM partners
WHERE name LIKE REPLACE('Manuel Fialho', ' ', '%');
SELECT name FROM partners WHERE name LIKE "Manuel%" OR name LIKE "%Fialho";
If You are sure about the last name of the name then you can also use AND
SELECT name FROM partners WHERE name LIKE "Manuel%" AND name LIKE "%Fialho";
There are 2 possible options to search.
Split search string into multiple words and query with that many LIKE patterns.
select name FROM partners WHERE name LIKE '%Manuel%' or name like '%Fialho%'
If you are sure that the sequence of words in the search strings are to match with those in the column value then replace all spaces with % symbol and use with LIKE.
select name FROM partners
WHERE name LIKE concat( '%', replace( 'Manuel Fialho', ' ', '%' ), '%' )
Try Below Query:
It works fine..!
SELECT * FROM `partners` WHERE
`name` LIKE replace( 'Manuel Fialho', ' ', '%' ) OR
`name` LIKE replace('%Manuel Fialho%', ' ', '%' ) OR
`name` LIKE replace('%Manuel Fialho', ' ', '' ) OR
`name` LIKE replace('%Manuel Fialho%', ' ', '' );

I'm having an issue in searching last name in full name. It is working with %% but I don't what to use it because all has 'A' are showing. Is there any alternative way on search last name? For example I have a full name John Doe and I only searched Doe, how to get the result even if I searched the last name?
SELECT * FROM Customers where CustomerName LIKE '%Doe%' - this is working
Select * from table_name where Column_Name Like "%last_name"
that will select only full names ends by last_name
Here, I am shown you. Please, try this both of one.
SELECT FullName FROM dbo.TableA where FullName LIKE '%Choksi%'
SELECT SUBSTRING(FullName, CHARINDEX(' ', FullName) + 1, LEN(FullName)) AS [Last Name]
from dbo.TableA
where FullName like '%Choksi%'
The name column contains items like 'John Smith', 'Elsa John Sanders', 'LilJohn Thomson', 'John'.
How can I structure a query just to return the names with John but not LilJohn.
I cannot do a LIKE '%John%' as it would return 'LilJohn Thomson'.
Looks like this is the same as:
Search for "whole word match" in MySQL
The approach uses a slick regular expression.
Assuming a word is defined by a space, you can do:
where concat(' ', col, ' ') like '% John %'
The following expression should find all "John"s
a = 'John' OR
a LIKE 'John %' OR
a LIKE '% John %' OR
a LIKE '% John'
Please note that some other tricks also work, but may severely hit performance, like
CONCAT(" ",a," ") LIKE "% John %"
Try SIMILAR TO '%+John+%' using the + space wildcard.
You can use REGEXP function.
Try this:
SELECT *
FROM tableA a
WHERE a.name REGEXP '[[:<:]]John[[:>:]]'
I have a table with:
Name Surname and Outputname ( = Name Surname )
Name and Surname should always have a value, but some time are empty.
I need to select from table by surname and i can't use surname field.
I can't even change field values with a script because i get this table from an outside source and can be change any time.
Database is MySQL 4.x
Can i select by second word in Outputname starting with some letter?
something like
SELECT Outputname FROM USERS
WHERE seconword(Outputname) LIKE 'A%' SORT BY seconword(Outputname) ASC
try this
SELECT
SUBSTRING_INDEX(Outputname, ' ', -1) as SecondWord
FROM USERS
WHERE SUBSTRING_INDEX(Outputname, ' ', -1) LIKE 'A%'
ORDER BY SecondWord ASC
demo
One possible approach:
SELECT Surname
FROM (
SELECT SUBSTRING_INDEX(Outputname, ' ', -1)
AS Surname
FROM Users) AS S
WHERE Surname LIKE 'A%'
ORDER BY Surname;
SQL Fiddle. This method is based on assumption that Outputname's format is always 'FirstName LastName' (i.e., ' ' symbol is used as a delimiter, and used only once each time).
I didn't understand your question at all. So you only have access to Outputname (composed by two words name+surname) and you have to sort it by the second word right?
Try something like (it worked for me):
SELECT
Outputname,
SUBSTRING_INDEX(Outputname, ' ', -1) as SecondWord
FROM USERS
ORDER BY SecondWord ASC
Clause SUBSTRING_INDEX(Outputname, ' ', -1) as SecondWord returns the last word placed after a space. So If you have Outputname = 'Maria Callas' it returns 'Callas', if you have Outputname = 'Sophia Cecilia Kalos' it returns 'Kalos'.
Consider I am having tow fields in my table
field_profile_first_name_value field_profile_last_name_value
Victor Brecher
Abhi Jass
select field_profile_first_name_value, field_profile_last_name_value
from content_type_profile where field_profile_first_name_value LIKE '%Victor Bre%' OR
field_profile_last_name_value LIKE '%Victor Bre%'
I am having a auto complete text box.
When i enter the keyword as victor it will fetch the result. But if i give the first name and last name in the same time it will not produce the result.
That is if i give the keyword as Victor Brecher it will not produce the result.
How can i make to get the result if i enter first name and last name ?
How can i make it ?
Try :
select * from contracts
where lower(concat_ws(' ', field_profile_first_name_value, field_profile_last_name_value))
like lower('%Victor Bre%')
Well, even you don't need to use lower too. just use it simply.
select * from contracts where concat_ws(' ', field_profile_first_name_value,field_profile_last_name_value)
like '%Victor Bre%'
I would make use of soundex.
select * from contracts where SOUNDEX(concat_ws(' ', field_profile_first_name_value,field_profile_last_name_value)) = SOUNDEX('Victor Bre');
I suggest to use this code, so the search works also if the search input is the lastname before the name
SELECT
*
FROM
contracts
WHERE
CONCAT(firstname, ' ', lastname)) LIKE 'Victor Bre%'
OR CONCAT(lastname, ' ', firstname)) LIKE 'Victor Bre%';
Moreover, I tested this sql code with and without LOWER(), in mysql 5.7+ the search already do that.
In my table I store first name in the fName column and last name in the lName column, now I need to search them with a query, but I don't know the SQL!
example
lName | fName
-----------------
Tendulkar| Sachin
Ganguly | Sourav
Khan | Zaheer
Dhoni | Mahendra Singh
The user should get MAHENDRA SINGH DHONI if he searches for Mahendra Dhoni!
select concat(fName,' ',lName) fullname
from tbl
where concat(' ',fName,' ',lName,' ') like '% Mahendra %'
and concat(' ',fName,' ',lName,' ') like '% dhoni %'
This will most certainly put to rest any hopes of a well performing query
A variation on the theme
select concat(fName,' ',lName) fullname
from tbl
where (concat(fName,' ',lName) like '%Mahendra%dhoni%'
or concat(lName,' ',fName) like '%Mahendra%dhoni%')
The 2nd version doesn't care about full part matching, e.g. dhoni will match madhonie
Both of these queries find the name correctly. Note that there are % before and after the name to match, as well as % for every space in the name.
create table tbl (fname varchar(100), lname varchar(100));
insert tbl select 'Mahendra singh', 'dhoni';
select concat(fName,' ',lName) fullname
from tbl
where (concat(fName,' ',lName) like '%Mahendra%dhoni%'
or concat(lName,' ',fName) like '%Mahendra%dhoni%');
select concat(fName,' ',lName) fullname
from tbl
where (concat(fName,' ',lName) like '%dhoni%Mahendra%'
or concat(lName,' ',fName) like '%dhoni%Mahendra%');
You are not clear on the nature of the search inputs and specifically the level of flexibility. First, is the user given two boxes for first and last name or only a single search box? If the former, then the fast solution would be:
Select concat( fname, ' ', lname)
From MyTable
Where lname Like 'dhoni%'
And fname Like 'mahendra%'
The above query only searches for where the first part of the column value begins with the search values. However, if the user can type anything into a single search box, that is harder. If it is presumed that the user has typed <name part> space <name part>, then one solution that solves that specific problem where the user enters only two words is to split on the space and run something like:
Select concat( fname, ' ', lname)
From MyTable
Where ( lname Like '%dhoni%' And fname Like '%mahendra%' )
Or ( lname Like '%mahendra%' And fname Like '%dhoni%' )
However, that query will perform awful because it forces the system to scan the entire table each time it is executed. Further, what happens when they enter a three part name like Mahendra Singh Dhoni in your search? There are simply too many edge cases for this to be workable IMO. The right solution is to get a full text indexing engine like Lucene that will create a index across both columns and rank the quality of the match.
Lucene
I'm guessing your inputs are from two different textboxes, and hopefully you are using a stored procedure :).
declare #input1 nvarchar(50)
declare #input2 nvarchar(5)
set #input1 = 'Mahendra'
set #input2 = 'Dhoni'
select upper((fname + ' ' + lname)) as 'FullName'
from customer
where fname like '%' + #input1 + '%'
or fname like '%' + #input1 + '%'
or lname like '%' + #input2 + '%'
or lname like '%' + #input2 + '%'
If you have 1 input box, you will want to split your search term by the space and loop over your search terms against fname and lname columns using the like '%term%' syntax.
Another way would be to make a stored procedure that added fname and lname together and did a soundex match. this is where you match your search term against the sound of the word in the table. Google it should help, its pretty easy.
I am assuming you have 2 inputs and you are only getting part of the first name. If this is true then the following would work:
select concat(fname, ' ', lname)
from yourtable
where substring(fname, 1, 5) = 'mahen'
and lname = 'dhoni'
The advantage of this approach is that it will use the indexes on the column(s) or a combined index whereas the like queries always do full table scans.
You might also check out a search engine like sphinx or solr when you truly do not know the data you are receiving as those are far more flexible that database queries.
