I am trying to search zipcodes matchin in area of 25 miles.
lets say I got 10 zip codes from my function that holds true.
now I have my value in a variable like this:
$zip_res = A0A 1B0, A0A 1G0, ...
column name is postal_code.
How can I match all values at once with postal_code?
I can not use loop, I have to do it in one time.
any suggestions are welcome.
Edit
MySQL statement where $zip_res is used
$sql= "SELECT distinct(p.id), p.extra FROM practitioner p INNER JOIN practitioner_category pc ON pc.practitioner_id = p.id AND pc.category_id = ";
$sql .= "'" .$this->category. "' ";
$sql .= "AND p.primary_postal_code in " .$zip_res. " WHERE 1 AND p.status = 1 ";
It looks like you're just looking for the IN keyword:
SELECT * FROM TABLE_NAME WHERE POSTAL_CODE IN ($zip_res);
Just as a note, however, you need to be able to quote all of those items first. So you might do this before using the above query:
$zip_res = "'" . str_replace(',',"','",$zip_res) . "'";
You can try to use
select ... from ... where postal_code ALL($zip_res).
But I'm not sure because of in accordance to manual you should use subqueries.
See http://dev.mysql.com/doc/refman/5.5/en/all-subqueries.html

2 more columns were recently added to a table with already lots of columns and rows.
These 2 columns (B and C) must contain similar values that the table had already from another column, A.
table.A:
2018-05-15h00:00/2018-05-15h23:00 [text] (value may differ but format is the same)
table.B must be:
2018-05-15 00:00:00 [Timestamp without timezone]
table.C must be:
2018-05-15 23:00:00 [Timestamp without timezone]
It would be quite easy from PHP (please don't mind the code, it's just an example):
<?php
$query = "SELECT a FROM table;";
$result = pg_query($conn, $query);
while ($row = pg_fetch_assoc($result)) {
$var = explode("/", $row[0]);
$varB = str_replace("h", " ", $var[0]);
$varB .= ":00";
$varC = str_replace("h", " ", $var[1]);
$varC .= ":00";
$query = pg_query($conn, "UPDATE table SET b='$varB', c='$varC' WHERE a='$row[0]';" );
}
?>
But I would rather use a proper method for that. I'm not sure for how long this SQL will run, the idea is to make the job as smooth as possible. If PHP is the best choice here, I'd go for this. Looking for suggestions.
Thanks!
You can use just a MySQL query instead of PHP calls
UPDATE Table_B
SET
Table_B.col1 = Table_A.col1,
Table_B.col2 = Table_A.col2
FROM
Tableone AS Table_B
INNER JOIN TableTwo AS Table_A
ON Table_B.some_id = Table_A.some_id
I have four tables:
tournaments (id, name, slots, price, gameId, platformId)
games (id, name)
platforms (id, name)
participations (id, tournamentId, playerId)
I want to get tournament's game name, platform name, slots, price, reservedSlots (participations count), information whether some player (his id is provided by php) participate in this tournament (bool/true) and conditions are:
- gameId must be in specified array provided by php
- platformId must be in specified array provided by php
I have created something like this but it doesn't work correctly:
php:
$platformsList = "'". implode("', '", $platforms) ."'"; //
$gamesList = "'". implode("', '", $games). "'";
mysql:
SELECT
t. NAME AS tournamentName,
t.id,
t.slots,
p. NAME,
g. NAME AS gameName,
t.price
FROM
tournaments AS t,
platforms AS p,
games AS g,
participations AS part
WHERE
t.PlatformId = p.Id
AND t.GameId = g.Id
AND t.Slots - (
SELECT
count(*)
FROM
participations
WHERE
TournamentId = t.id
) > 0
AND part.TournamentId = t.Id
AND t.PlatformId IN ($platformsList)
AND t.GameId IN ($gamesList)
I will not dwelve into handling your post and get values, I will assume that everything is all right:
$possibleGameIDs = getPossibleGameIDs(); //function will return the array you need for possible game id values. Inside your function make sure that the id values are really numeric
$possiblePlatformIDs = getPossiblePlatformIDs(); //function will return the array you need for possible platform id values. Inside your function make sure that the id values are really numeric
$playerId = getPlayerId(); //function returns the player id and makes sure that it is really a number
$sql = "select games.name, platforms.name, tournaments.slots, tournaments.price, ".
"(select count(*) from participations where participations.tournamentId = tournaments.tournamentId) as reservedSlots, ".
"(select count(*) > 0 from participations where participations.tournamentId = tournaments.tournamentId and playerId = ".$playerId.") as isParticipating ".
"from tournamens ".
"join games ".
"on tournaments.gameId = games.id ".
"join platforms ".
"on tournaments.platformId = platforms.id ".
"where games.id in (".implode(",", $possibleGameIDs).") and ".
" platforms.id in (".implode(",", $possiblePlatformIDs).") and ".
" tournaments.slots > 0"
Code was not tested, so please, let me know if you experience any problems using it. Naturally you need to run it, but as you did not specify what do you use to run the query, I did not allocate time to deal with technical details of running it. Beware SQL injections though.
I am sure this is possible but I think it maybe just very complex to write. I want to search every field by:
='SearchTerm'
then
Like %SearchTerm
then
like SearchTerm%
and finally
like %SearchTerm%. I want to run this on every field in my table which there is around 30 or 40. Is there an easy way to run this over multiple fields or will I have to declare every single one?
I think I have seen a query before where different matches between %query %query% etc are ranked by assigning an integer value and then ordering by this. Would that be possible on a query like this?
Any advice and help in the right direction is much appreciated.
You should use fulltext indexing on the fields you want searched and use MATCH AGAINST instead of LIKE %%. It's much faster and returns results based on relevancy. More info here:
Mysql match...against vs. simple like "%term%"
I do something very similar to what you're describing (in php and mysql)
Here's my code:
$search = trim($_GET["search"]);
$searches = explode(" ",$search);
$sql = "SELECT *,wordmatch+descmatch+usagematch+bymatch as `match` FROM (SELECT id,word,LEFT(description,100)as description,
IFNULL((SELECT sum(vote)
FROM vote v
WHERE v.definition_id = d.id),0) as votecount,
";
$sqlword = "";
$sqldesc = "";
$sqlusage = "";
$sqlby = "";
foreach ($searches as $value) {
$value = mysqli_real_escape_string($con,$value);
$sqlword = $sqlword . "+ IFNULL(ROUND((LENGTH(word) - LENGTH(REPLACE(UPPER(word), UPPER('$value'), '')))/LENGTH('$value')),0)";
$sqldesc = $sqldesc . "+ IFNULL(ROUND((LENGTH(description) - LENGTH(REPLACE(UPPER(description), UPPER('$value'), '')))/LENGTH('$value')),0)";
$sqlusage = $sqlusage . "+ IFNULL(ROUND((LENGTH(`usage`) - LENGTH(REPLACE(UPPER(`usage`), UPPER('$value'), '')))/LENGTH('$value')),0)";
$sqlby = $sqlby . "+ IFNULL(ROUND((LENGTH(`by`) - LENGTH(REPLACE(UPPER(`by`), UPPER('$value'), '')))/LENGTH('$value')),0)";
}
$sql = $sql . $sqlword ." as wordmatch,"
. $sqldesc ." as descmatch,"
. $sqlusage ." as usagematch,"
. $sqlby ." as bymatch
FROM definition d
HAVING (wordmatch > 0 OR descmatch > 0 OR usagematch > 0 OR bymatch > 0)
ORDER BY
wordmatch DESC,
descmatch DESC,
usagematch DESC,
bymatch DESC,
votecount DESC)T1";
$queries[] = $sql;
$result = mysqli_query($con,$sql);
You can see this at work http://unurbandictionary.comule.com/view_search.php?search=George+Miley+Cyrus this is when I search for "George Miley Cyrus"
What it does is it explodes the search string to find each word and returns the number of occurences of each word in each of my column, and then i do an ORDER BY to have relevance (priority) to come back first. So in my case word field has the highest relevance, then description field, then usage field, then by field.
Before this version of my code I was using LIKE but it didn't give me a count of occurences, since I want the row with the most occurences of my search word to return first before other rows.
You should really have some sort of id to select the rows in your table.
You should have put a column with
id INT NOT NULL AUTO_INCREMENT PRIMARY KEY
Then you could use
SELECT * FROM table WHERE column1 LIKE "%SearchTerm%" AND id BETWEEN 1 AND 40
Im new to php and my sql in trying to get all the results from this table if nothing is selected but for some reason its always displaying one result. Any ide why
$query = "SELECT *, ROUND(AVG(d.rating),0) FROM restaurant AS r, review AS d WHERE 1=1 ";
if($vicinity) $query .= "AND r.vicinity=\"$vicinity\" ";
if($cuisine) $query .= "AND r.cuisine=\"$cuisine\" ";
if($price) $query .= "AND r.price=\"$price\"";
if($name) $query .= "AND r.name LIKE \"%$name%\"";
$result = mysql_query($query);
while($row = mysql_fetch_array($result)) {
and im only getting the first item on the table
I would look into PDO personally. You can find out a lot about it in the manual here.
guessing you're only getting one result because the avg call without a group by is triggering some interesting behavior. try adding a group by, and i'm guessing you also want to associate the restaurants and reviews with a join. eg:
$query = "SELECT *, ROUND(AVG(d.rating),0) FROM restaurant AS r LEFT JOIN review AS d on r.id = d.restaurant_id WHERE 1=1";
...
...
$query .= ' GROUP BY r.id';
$result = mysql_query($query);
per the thread, sounds like you should look into prepared statements as well :). and the SELECT * should probably also just be SELECT r.* - the data returned as part of the * results from the rating won't be meaningful after the group by (the r.* and round(avg(d.rating),0) values should be though)
Try to use prepared statements and get results and use iterator to parse and print in a loop will get. See also this tutorial.
Ive got the query below :
$sql = "SELECT `scanners`.`KordNo`, `scanners`.`BundleNumber`
FROM `scanners`, `TWOrder`, `Stock`
INNER JOIN `TWORDER` ON `scanners`.`KordNo` = `TWOrder`.`KOrdNo`
AND `scanners`.`Date` = '" . $date . "'
INNER JOIN `Stock` ON `TWOrder`.`Product` =`Stock`.`ProductCode`
AND `Stock`.`ProductGroup` NOT BETWEEN 400 AND 650
AND `scanners`.`Scanner` IN (
ORDER BY `scanners`.`KordNo` ASC";
foreach($scanner as $x)
{$sql .= $x . ",";}
$sql .= "0);";
// And query the database
$result = mysql_query($sql);
while($row = mysql_fetch_array($result))
$return[] = $row;
}
When i echo the sql on php my admin i get the error not a unique table/alias stock;
can someone advise?
Since you're using explicit JOINs, drop the other two tables off of the FROM clause.
...
FROM `scanners`
INNER JOIN `TWORDER` ON `scanners`.`KordNo` = `TWOrder`.`KOrdNo`
...
On line 2 you have...
FROM `scanners`, `TWOrder`, `Stock`
Then you have some INNER JOINs on to TWOrder and Stock.
That's mixing syntax (, and JOIN) which is messy. Stick to JOIN
It means that TWOrder and Stock are mentioned Twice in the query
If you REALLY need to include those table multiple times in one query, you need to give them alias names, so they can be distiguished from each other.
But I think it's probably a mistake and that Line 2 should just be
FROM `scanners`
Then, also, I'm not sure how you got that to compile. You have IN ( and then an ORDER BY clause, to which you append a list of values. You should append the list before the ORDER BY and then append the ORDER BY after you've finished the loop.
