I'm looking for a method to get rows that are more similar with inserted string
For example:
SELECT * FROM db WHERE column have part of '$search_string';
In other words if search string is My name is TOM and in the column I have
COLUMN
---------------
My name is Sara
My name is Jack
My dog is white
---------------
results must be:
all rows that contains My name is, because they are most similar to $search_string.
I've tried to use LIKE operator with phrase splatted in words, but I'm not obtaining the result that I want, any ideas?
What about
SELECT * FROM db WHERE COLUMN LIKE 'My name is %'
?
UPDATED
"SELECT * FROM db WHERE COLUMN LIKE '%$search%'"

I want to search for people whose name start with letter A using LIKE query but I'm getting errors. What query should I type in order to get results based on people whose name start with a particular letter or not with that letter?
Get result where name starts with a specific letter
SELECT * FROM table WHERE name LIKE 'A%'
Get result where name DOES NOT start with a specific letter
SELECT * FROM table WHERE name NOT LIKE 'A%'
Hello everyone as the topic says I am looking for alternative or advanced using of "LIKE".
I have column which contains a row of words p.e. "keyword1,keyword2,another_keyword" and when I use
$sql = mysql_query("SELECT * FROM table WHERE `column` LIKE '%keyword1%' ");
It hardly find it p.e. this example works but when i try to find shorter strings it has problems and sometimes it does not find anything.
I tried put a whitespace after comas and it helped but if there is a way where I can search for match with this specification of column I would be happy.
You may move keywords into individual table.
Or you can use SET field type, if the list of your keywords don't change.
Storing comma separated list of your words is a bad idea example using like in your scenario is hard to find the exact work in comma separated list instead you can add new table which relates to your current table and store each the word in a new row with the associated identity like
table1
id title
1 test1
2 test2
kewords_table
table1_id word
1 word1
1 word2
1 word3
and query will be
select t.*
from table1 t
join kewords_table k
on(t.id = k.table1_id)
where k.word = 'your_keyword'
If you can't alter your structure you can use find_in_set()
SELECT * FROM table WHERE find_in_set('your_keyword',`column`) > 0
try something like this:
SELECT * FROM tablename
WHERE column LIKE '%keyword1%'
OR column LIKE '%keyword2%';

MySQL allows you to perform a full-text search based on very complex queries in the Boolean mode along with Boolean operators. This is why the full-text search in Boolean mode is suitable for experienced users.
First You have to add FULLTEXT index to that perticuler column :
ALTER TABLE table_name ADD search_column TEXT CHARACTER SET utf8mb4 COLLATE utf8mb4_general_ci NULL DEFAULT NULL, ADD FULLTEXT search_column (search_column);
Run following query for searching :
SELECT * FROM table WHERE MATCH(search_column) AGAINST("keyword1")

I have to make a search for keywords as part of my Computer Science work.
I have the names and descriptions of several DVD's.
The user has to search a word, and then displayed are all the names of DVD's where the word appeared in either the title or description.
Let's say my columns in my table
were "dvd title" and "description", and the word the person has entered is $keyword.
How would i select rows in mysql where $keyword appears at least once in either columns "dvd title" and "description".
Thanks for reading. Any help appreciated.
You could create a full text index on those columns, but that probably isn't what they want you do do.
You need wildcards, and to you wildcards compare with the keyword LIKE instead of =. A wildcard in mysql is %
SELECT * FROM mutable WHERE dvdtitle like '%keyword%' or description like '%keyword%';
As for using PHP variable and creating the string, you've got to do some of your own homework.
$sql = "SELECT * FROM table_name WHERE dvdtitle LIKE '%".$keyword."%' OR description LIKE '%".$keyword."%'";
Executing the above SQL query would return all the rows in the table that has the specified keyword in either the column dvdtitle or description.
Use this query:
SELECT *
FROM table_name
WHERE dvd_title like '%$keyword%'
OR description like '%$keyword%'
You can use following code sample, it's not a full code but will give you an idea:
$query_str = "select * from dvd_table_name where dvd_title like '%$keyword%' or description like '%$keyword%'";
$qh = mysql_query($query_str);
Then use mysql_fetch_assoc($qh) to retrive data using while loop;
OK, I have a DB table that's called players and each player has a forename and surname. Then I have a PHP Ajax search thing that I call to search for players. For example... in the input box, someone types James and there's a row in the table with forename and surname James and Smith respetively.
I do this $check = mysql_query("SELECT * FROMplayersWHEREsurnameLIKE '%$name%' ORforenameLIKE '%$name%' LIMIT 0, 10") or die(mysql_error());
And it returns at least 10 with either forename or surname like the keyword James. However, if I type James Smith, despite it being in the table, I get zero results.
How do I fix this?
Are you using InnoDB or MyISAM? If your using MyISAM, you can create a single field which holds the combined name and then search it using a full text index. So lets imagine you add a new field called combined_names you would search it like this
SELECT * FROM table WHERE match(combined_names) against('John Smith');
This would find any row with either John or Smith in, you can change it to match only those rows with both parts you would add plusses like so:
SELECT * FROM table WHERE match(combined_names) against('+John +Smith');
Here is the documentation on the MySQL site where you can find out more:
http://dev.mysql.com/doc/refman/5.0/en/fulltext-search.html
SELECT * FROM players WHERE CONCAT(forename, ' ', surname) = '$name' OR forename LIKE '%$name%' OR surname LIKE '%$name%'
split the name up on spaces so the query runs twice (if there is one space)
the query will run for both names
$nameBits = explode($name," ");
run the query for each piece of $nameBits
surname LIKE '%$nameBits[$i]%'
I have a MySQL database and a table which has a names column as follows:
id name age
1 samuel lee 31
2 doug sokira 32
3 vernon smith 33
I would like to search through the database for names. I have this query so far:
SELECT * FROM table WHERE name LIKE 's%'
This would return me the first record with ID 1.
However, i would like the query to further do the search from the text separated by the space as well. So, to put in words the search should be done through both first name and last name.
I'm willing to stick to this database design where first name and last name are stored in one single column.
So, the above query should return rows 1, 2 and 3.
How should i formulate my query?
SELECT * From table WHERE name LIKE 's%' OR name LIKE '% s%'
Note that this cannot use any index and therefore will always be dog-slow. Please reconsider splitting the columns.
SELECT * FROM table WHERE name LIKE '%s%'
that would return row 1, 2, and 3 since they all contain an 's'.
