I have a table with fullname column. I want to make a query for finding a person via his last name but his last name is in the full name column.
Would it matter if it accidentally returned someone whose first name matched your query?
A simple query would be:
SELECT *
FROM TABLE
WHERE fullname LIKE '%insertlastname%'
If you want to define the last name as the name after the last space:
SELECT substring_index(fullname, ' ', -1) as lastname
FROM TABLE
WHERE lastname='insertlastname'
Two suboptimal answers, but some answers at least.
enter code here You can use this if you want to fetch by query:
SELECT SUBSTRING_INDEX(SUBSTRING_INDEX( `fullname` , ' ', 2 ),' ',1) AS b,
SUBSTRING_INDEX(SUBSTRING_INDEX( `fullname` , ' ', -1 ),' ',2) AS c FROM `users` WHERE `userid`='1'
But you can also try by PHP to fetch last name. You just use explode function to fetch last name.
Exm:
$full_name = "row moin";
$pieces = explode(" ", $fullname);
echo $first_name = $pieces[0]; // row
echo $last_name = $pieces[1]; // moin
A simple answer for this is like this suppose we have a name
Charles Dickens
:
SELECT * FROM TABLE_NAME WHERE SUBSTRING_INDEX(FULLNAME,' ',-1) like '%Dickens';

How i can get value like this in a variable 'TFSEP-2019','TFjul-2018','TFJun-2018' without spaces.
SELECT s.house, s.grade, s.homeroom AS Campus

GROUP BY s.house
I am getting like this ('TFJun-2018 TFJUL-2018 TFSEP-2019') but I want like ('TFSEP-2019','TFjul-2018','TFJun-2018') please help
You may refer the following statements with like operators, whenever you need quotes('), use doubled-quotes('') :
create table tab ( Id int, expression varchar(100));
insert into tab values(1 ,'TFJun-2018 TFJUL-2018 TFSEP-2019');
insert into tab values(2,'''TFJun-2018'',''TFJUL-2018'',''TFSEP-2019''');
select * from tab where expression like '''TFJun-2018''%';
Id expression
2 'TFJun-2018','TFJUL-2018','TFSEP-2019'
or
select * from tab where expression like '''TFJun-2018'',''TFJUL-2018''%';
Id expression
2 'TFJun-2018','TFJUL-2018','TFSEP-2019'
or
select * from tab where expression like '''TFJun-2018'',''TFJUL-2018'',''TFSEP-2019''%';
Id expression
2 'TFJun-2018','TFJUL-2018','TFSEP-2019'

You can use like for strings
% means any chars, _ means one char
So doing
F.name like %2018%
Will give you all of 2018..
use explicit join and concat
SELECT
concat( concat( concat( concat("'",s.house),"'"),concat( concat("'",s.grade),"'")),
concat( concat("'",s.homeroom),"'"))
FROM student s join fees_jrl f
on s.studnum = f.studnum
where f.name IN (' TFJun-2018 TFJul-2018 ') AND
f.trans_type= 'chg' AND
f.paid_id is NULL AND s.house LIKE '%'
I think you dont need group by as you have no aggregation function
I have a table which consists of 5000 rows. I need SQL command that could update each row by removing all values in "(...)" if only one couple of () is found.
Basically, if I have a name in a row:
Name surname (extra info)
I need to remove "(extra info)" and leave only Name surname
But if there is no additional couple of ()
If there is a row
Name Surname(data) (extra info)
The script should not amend this name
In simple words, I need to update a name where is only one ( or ) symbol
Many thanks
can you try to find first '(' and substring to it ?
don't forget to use case for none ( in string
update userlogin
set fullname = case position('(' in FullName)
when 0
then fullname
else substring(Fullname,1,position('(' in FullName) - 1)
end
This is an implementation of my question. I used select to let me check the result before applying it to update request. The script shows a table of
3 columns: Id, Name, UpdatedName, where Name is what we have and UpdatedName what we will obtain
SELECT `Id`,`Name`,
(case when ((LENGTH(`Name`)-LENGTH(REPLACE(`Name`, '(', ''))) = 1)
THEN
SUBSTRING_INDEX(`Name`, '(', 1)
ELSE
'-'
END)
as updated_name,
FROM table
WHERE (LENGTH(`Name`)-LENGTH(REPLACE(`Name`, '(', ''))) = 1
LIMIT 0,1500
P.S. I used Id to allow me to amend values
SELECT CASE
WHEN fname = 'correct' THEN 'your condition'
WHEN sname = 'correct' THEN 'your second condition'
ELSE 'baz'
END AS fullname
FROM `databasetable`
or you can do as like also
CASE
WHEN action = 'update' THEN
UPDATE sometable SET column = value WHERE condition;
WHEN action = 'create' THEN
INSERT INTO sometable (column) VALUES (value);
END CASE
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

I have a table with some problem data. For example, the table is as follow :
ID NAME JOB
--- --------------------------- ---------------
1 Peter Teacher
2 John Programmer
3 Tom**He is a Teacher
4 Alan**He is a Accountant
The problem is some data has been correctly inserted but some hasn't. Now I want to execute an SQL in order to make the table looks like below :
ID NAME JOB
--- --------------------------- ---------------
1 Peter Teacher
2 John Programmer
3 Tom Teacher
4 Alan Accountant
I am not familiar with SQL Statement so I can just think of using the following PHP Script to fix this problem.
$sql1 = "SELECT NAME FROM MY_TABLE WHERE JOB = '' AND NAME LIKE '%He is a %'";
$res1 = mysql_query($sql1);
while($row1 = mysql_fetch_array($res1)){
$new_data = explode("**He is a ", $row1["NAME"]);
$sql2 = "UPDATE MY_TABLE SET NAME = '".$data[0]."', JOB = '".$data[1]."' WHERE ID = '".$data["ID"]."'";
mysql_query($sql2);
}
Can anyone suggest a better way for me to fix this problem with one or a few SQL Statement ? Thanks
UPDATE
SET NAME = SUBSTRING_INDEX(SUBSTRING_INDEX(NAME, '**He is a ', 1), ' ', -1),
job = SUBSTRING_INDEX(SUBSTRING_INDEX(NAME, '**He is a ', 2), ' ', -1)
WHERE NAME LIKE '%**He is a %'
You can use the substring_index function to break up the string, and apply all the changes in a single update statement:
UPDATE my_table
SET JOB = SUBSTRING_INDEX (name, '**He is a ', -1),
name = SUBSTRING_INDEX (name, '**He is a ', 1),
WHERE name LIKE '%**He is a %' AND
(job IS NULL OR job = '') -- Just to be on the safe side
There are two columns in a MySQL table: SUBJECT and YEAR.
I want to generate an alphanumeric unique number which holds the concatenated data from SUBJECT and YEAR.
How can I do this? Is it possible to use a simple operator like +?
You can use the CONCAT function like this:
SELECT CONCAT(`SUBJECT`, ' ', `YEAR`) FROM `table`
Update:
To get that result you can try this:
SET #rn := 0;
SELECT CONCAT(`SUBJECT`,'-',`YEAR`,'-',LPAD(#rn := #rn+1,3,'0'))
FROM `table`
You can use mysql built in CONCAT() for this.
SELECT CONCAT(`name`, ' ', `email`) as password_email FROM `table`;
change field name as your requirement
then the result is
and if you want to concat same field using other field which same then
SELECT filed1 as category,filed2 as item, GROUP_CONCAT(CAST(filed2 as CHAR)) as item_name FROM `table` group by filed1
then this is output
In php, we have two option to concatenate table columns.
First Option using Query
In query, CONCAT keyword used to concatenate two columns
SELECT CONCAT(`SUBJECT`,'_', `YEAR`) AS subject_year FROM `table_name`;
Second Option using symbol ( . )
After fetch the data from database table, assign the values to variable, then using ( . ) Symbol and concatenate the values
$subject = $row['SUBJECT'];
$year = $row['YEAR'];
$subject_year = $subject . "_" . $year;
Instead of underscore( _ ) , we will use the spaces, comma, letters,numbers..etc
In query, CONCAT_WS() function.
This function not only add multiple string values and makes them a single string value. It also let you define separator ( ” “, ” , “, ” – “,” _ “, etc.).
Syntax –
CONCAT_WS( SEPERATOR, column1, column2, ... )
Example
SELECT
topic,
CONCAT_WS( " ", subject, year ) AS subject_year
FROM table
I have two columns:
prenom and nom so to concatenate into a column with name chauffeur_sortant I used this script:
SELECT date as depart, retour, duree_mission, duree_utilisation, difference, observation, concat( tb_chaufeur_sortant.prenom, ' ', tb_chaufeur_sortant.nom) as chauffeur_sortant, concat(tb_chaufeur_entrant.prenom, ' ', tb_chaufeur_entrant.nom) as chauffeur_entrant
FROM tb_passation
INNER JOIN tb_vehicule
ON tb_vehicule.id = tb_passation.id_vehicule
INNER JOIN tb_chaufeur_sortant
ON tb_chaufeur_sortant.id = tb_passation.id_sortant
INNER JOIN tb_chaufeur_entrant
ON tb_chaufeur_entrant.id = tb_passation.id_entrant WHERE tb_vehicule.id = '';
$crud->set_relation('id','students','{first_name} {last_name}');
$crud->display_as('student_id','Students Name');
