I'm not getting the result I need and I'm sure it is a small problem here.
I have a column(mfg_req) in my database which have a record with 10M.
My variable in php does have the text 10M40SABCDE.
What I want is to search in my table and get the results starting with this variable.
My MYSQL query does look like below but no results:
SELECT * FROM specific_req WHERE mfg_req LIKE '10M40SABCDE%'
I also tried the below query but no results
SELECT * FROM specific_req WHERE mfg_req LIKE '%10M40SABCDE%'
Also tried the below but it shows me all records except the one I need with 10M
SELECT * FROM specific_req WHERE '10M40SABCDE' LIKE CONCAT('%',mfg_req)
I have tried to put the % behind mfg_req but then it will show me all records including the one I need.
I cannot figure it out how to get the result I need. If someone can help me with my query I would appreciate it a lot.
Thanks!
Let's say:
$var = '10M40SABCDE';
...then your SQL statement must be:
$sql = "SELECT * FROM specific_req WHERE mfg_req LIKE '{$var}%'";
It would be best if you show a snippet of your code, too.

I'm trying to execute a query in my php script. I simply try to select the row that contains following post data but it always return 2.
$karakterara = $baglan->prepare("SELECT * FROM karakterler WHERE Isim=? OR MaskeID=? OR StaffName=?");
$karakterara->execute(array($_POST['soyuncu'], $_POST['soyuncu'], $_POST['soyuncu']));
$aranan = $karakterara->fetch();
I think that I'm missing something or I'm trying not the right way. Can anyone help me?
I have a loop that is producing a string like $sku = MAR-9-870-2-L. I have a database that is a list of "skusearchquery" that often look like skusearchquery = MAR-9. I am trying to do a search for all rows of the database that have a skusearchquery contained inside the string $sku.
I know the code below doesn't work because MAR-9-870-20-L is NOT LIKE MAR-9-870 because MAR-9-870 doesn't contain the longer string, so I'm wondering how I can say: if the row value skusearchquery matches part of the string MAR-9-870-20-L, then select it.
$search = mysqli_query($connect, "SELECT * FROM skusearch WHERE skusearchquery LIKE '%$sku%'");
Please try the LOCATE() function:
$search=mysqli_query($connect,"SELECT * FROM skusearch WHERE LOCATE(`skusearchquery`,'$sku'");
...if this tests positively, you should take tadman's advice and protect your query.
As you said, that your searchquery field can have smaller part of sku then you can try below query to get those results as well
$search = mysqli_query($connect, "SELECT * FROM skusearch WHERE skusearchquery LIKE '%$sku%'" or '$sku' like concat('%',skusearchquery,'%');
Also make sure to protect your queries from sql injection as suggested by #tadman.
Hi there i am working on PHP code that is selecting columns from two tables.
Here is my code:
$result2 = mysql_query("SELECT *
FROM `videos`, `m_subedvids`
WHERE `videos.approved`='yes' AND
`videos.user_id`='$subedFOR'
ORDER BY `videos.indexer`
DESC LIMIT $newVID");
while($row2 = mysql_fetch_array($result2))
{
$indexer = addslashes($row2['videos.indexer']);
$title_seo = addslashes($row2['videos.title_seo']);
$video_id = addslashes($row2['videos.video_id']);
$title = addslashes($row2['videos.title']);
$number_of_views = addslashes($row2['videos.number_of_views']);
$video_length = addslashes($row2['videos.video_length']);
}
When i try to print $indexer with echo $indexer; it's not giving me any results.
Where is my mistake in this code?
It seems to me like the key 'indexer' isn't in your results. It's hard to tell, since you haven't listed a definition for your table and you're using SELECT * so we can't see the names.
It makes the program easier to read later, if instead of SELECT *..., you use SELECT col1, col2, .... Yes, SELECT * will save you some typing right now, but you'll lose that time later when you or anyone else who works on your code has to check the table definition every time they work with that line of code.
So, try changing your query to explicitly select the columns you use. If it's an invalid column you'll get an error right away rather than this silent failure you're getting now, and you'll thank yourself later as well.
So long as videos.indexer is a unique field name among all tables used in the query you can change
$indexer = addslashes($row2['videos.indexer']);
to
$indexer = addslashes($row2['indexer']);
You don't need to (or can not) use the table name when referring to the result.
I have a table with a lot of data, so I retrieve it and display it one page at a time (my request is lengthy so there is no way I run it on the entire table).
But I would like to paginate the results, so I need to know what is the total number of elements in my table.
If I perform a COUNT(*) in the same request, I get the number of selected elements (in my case, 10).
If I perform a COUNT(*) on my table in a second request, the result might be wrong because of the where, join and having clauses in my main query.
What is the cleanest way to:
Retrieve the data
Know the maximum number of elements in my table for this specific request
One solution seems to be using the Mysql function FOUND_ROWS :
I tried this, as mysql_query performs one query at a time: (taken here)
$query = 'SELECT SQL_CALC_FOUND_ROWS * FROM Users';
$result = mysql_query($query);
// fetching the results ...
$query = 'SELECT FOUND_ROWS()';
$ result = mysql_query($query);
// debug
while ($row = mysql_fetch_row($result)) {
print_r($row);
}
And I got an array with 0 results:
Array ( [0] => 0 )
Whereas my query does returns results.
What is wrong with my approach ? Do you have a better solution ?
Set mysql.trace_mode to Off if it is On.
ini_set('mysql.trace_mode','Off'); may also work depending on your host configuration if you cannot edit my.cnf
If that doesn't make the code you posted above work, then you will need to run the query again without LIMIT and count it that way.
The code above works fine. I wasn't opening the connection correctly.
Output is :
Array ( [0] => 10976 )
I am still interested for an other way to do it, especially something that is not mysql dependent.
I have a script that automatically populates a mysql database with data every hour. It populates the date field like 03/17/10.12:34:11 and so on.
I'm working on pulling data based on 1 day at a time from a search script.
If i use
SELECT *
FROM call_logs
WHERE call_initiated between '03/17/10.12:00:00' and '03/17/10.13:00:00'
it works, but when I try to add the rest of the search params, it ignores the call_initiated field.
SELECT *
FROM call_logs
WHERE caller_dn = '2x9xxx0000' OR called_dn = '2x9xxx0000'
AND call_initiated between '03/17/10.12:00:00' and '03/17/10.13:00:00'
^-- I x'd out a couple of the numbers. I've also tried without the between function, and used >= <= to pull the records, but have the same results. Im sure its an oversight, thanks in advance.
try using parentheses around your OR statement
... where (caller_dn='2x9xxx0000' OR called_dn='2x9xxx0000') AND call_initiated between '03/17/10.12:00:00' and '03/17/10.13:00:00'
use the IN operator instead of OR
... where caller_dn IN('2x9xxx0000','2y9yyyy000') AND call_initiated between '03/17/10.12:00:00' and '03/17/10.13:00:00'
The OR statement is more than likely the issue, since OR evaluates the left side, sees that its true, it doesn't care what is on the right site, because as long as one of the statements is true, it considiers the entire statement to be true.
Read up on the OR operator at the MYSQL page
Your Statement should look like
SELECT * FROM `call_logs` WHERE (caller_dn='2x9xxx0000' OR called_dn='2x9xxx0000') AND call_initiated BETWEEN '03/17/10.12:00:00' and '03/17/10.13:00:00';
