SELECT *
FROM customers
WHERE Firstname LIKE 'George'
The problem is that i have more than 1 rows in the table with tha name Geoge and the result of the query shows only one row
You will want to include the wildcard % character to include the rows the have George present in the name:
SELECT *
FROM customers
WHERE Firstname LIKE '%George%';
If George will always appear at the beginning, then you can include the wildcard on the end:
SELECT *
FROM customers
WHERE Firstname LIKE 'George%';
you need to add a wildcard character % to match any value that contains george
SELECT *
FROM customers
WHERE Firstname LIKE '%George%'
MySQL LIKE Operator
the statement
WHERE Firstname LIKE 'George'
is equivalent with
WHERE Firstname = 'George'
that is why you are only getting one record which firstname is george.

try
LOWER(Firstname) LIKE '%george%'

I have a teachers table that looks like this:
teacherid
teacherfname
teacherlname
salary
1
Alexander
Bennett
55.30
I would like to return any record that contains a given string in the teacherfname, teacherlname and salary columns.
What I have right now (this returns exact match only):
SELECT * FROM `teachers` WHERE 'Alexander' IN (teacherfname, teacherlname, salary)
What I would like to do is something like this (this would not return anything):
SELECT * FROM `teachers` WHERE '%Alex%' IN (teacherfname, teacherlname, salary)
What do I need to make the query work? Thank you.
I would assume that the value %Alex% won't ever match the salary column. If you want to search for any rows where the first name or last name include "Alex" I would use simple pattern matching, and force all comparisons to use the same letter case.
For example:
SELECT *
FROM `teachers`
WHERE lower(teacherfname) like '%alex%'
or lower(teacherlname) like '%alex%'
My table name is student and column name is FullName.
Can anyone help with this question? I have tried:
select FullName from student where fullName like "e"
But this is returning 0 rows.
If you want students that contain at leas one 'e', then:
select fullname
from student
where fullname like '%e%'
Note the use of the wildcard character (%) around the e, which searches for the character anywhere in the string.
But if you really mean students that contain a single e (not more, not less), then you need to filter out names that contain more than one. For this, you can do:
select fullname
from student
where fullname like '%e%' and fullname not like '%e%e%'
You could also use replace() and char_length():
select fullname
from student
where char_length(replace(fullname, 'e', '')) = char_length(fullname) - 1
You can use a regular expression:
select fullname
from student
where fullname regexp '^[^e]*e[^e]*$'
i want some correction here. i want to select all people with name fred in database
Here's my query:
SELECT * FROM tdble WHERE CONCAT(name) LIKE CONCAT('%', REPLACE('fred', '')'%')
What you are asking can be simply achieved by either using the "=" operator of the wildcard operator "like" statement.
If you wish to find all records that have an exact match to the name 'Fred' then you should model your query as so:
Select * From tdble Where Name = 'fred'
However, if you want to get all results where the names have 'fred' included in it somewhere use the wildcard operator.
Select * From tdble Where Name like '%fred%'
Also you can further model your query to know where exactly in which form you want 'fred' to appear. Example if you want 'Fred' to be as the last characters of your name string, for instance you wish to get names which ends with fred then model your query like this:
Select * From tdble Where Name like '%fred'
(you will get results like 'alfred', provided there is an alfred in your table)
However if you wish to get all names that begin with fred, model the query like this:
Select * From tdble Where Name like 'fred%'
(you will get results like 'fredinane', provided there is a fredinane in your table)
Cheers
If you want to fetch record with name 'fred', you can simply do Select * from TableName Where Name = 'fred'.
If you want to fetch records which their names' string contain 'fred', you have to use select * from TableName where Name like '%fred%'
I have a query such as the below:
SELECT * from table_name where lastname regexp "[[:<:]]Smith[[:>:]]"
This returns
De Smith
Smith
I only need to retrieve Smith
I even tried the below
SELECT * from surnames where last_name regexp "[[:<:]][^\s]Smith[[:>:]]"
I may be mistaking your requirement, but if you want to exactly match a last name then you can just use the equals operator:
SELECT * from table_name where TRIM(lastname) = 'Smith'
I used TRIM() on the lastname field just in case there might be leading or trailing whitespace.
I'm trying to query the first letter of a last name in MySQL. I want to skip the first name and query the a certain letter in the last name. Thanks
In SKU_data, which SKU has a buyer whose last name begins with 'M'?
*/
select *
from sku_data
where buyer ;
In your where clause, search on WHERE buyer.LastName LIKE 'M%'. This will return all results that start with M.
You need to use a combination of the substring method and the substring_index method in your sql query.
Your select query should look something like this
SELECT SUBSTRING(last_name,1,1)
I'm assuming that your name field has both first and last name in it, instead of separate fields for first and last name. Use the substring_index method to figure out what last_name should be:
SUBSTRING_INDEX(full_name,' ',-1)
Combining this SQL, we have:
SELECT SUBSTRING(SUBSTRING_INDEX(buyer,' ',-1),1,1) as first_letter
Now you can use the first_letter field in a where clause to get your desired result:
SELECT *, SUBSTRING(SUBSTRING_INDEX(buyer,' ',-1),1,1) as first_letter
from sku_data
where first_letter = 'M' ;
Assuming that you have a field like say "full_name" which has first name and last name in the same column.
Lets say the full_name in table employee has a value "JEFF MOSTI"
You can simply use the following statement to get what you need
select * from employee where full_name regexp ' M';
I am assuming you are looking for the last name to start with 'M' and that there is a space (' ') between the first and last name.
