PHP - Due To Math In Query There Is An Error

Hi, i'm currently coding a new inbox for my website, but ive got an error which says:

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'to='NoName' ORDER BY id DESC' at line 1

Im not sure why ive got that as everything seems to be fine :S

My Code:


$user=$_SESSION['username'];
$get_messages = mysql_query("SELECT `id` FROM `inbox` WHERE to='$user' ORDER BY `id` DESC") or die("Error on line 9 - " . mysql_error());


Thanks for any help/advise given.

Code: [Select]
mysqli_fetch_assoc() expects parameter 1 to be mysqli_result, boolean
i get that error with this code:


$online_query = $link->simple_query('u_username', 'users', 'u_online=1 AND u_hidden != 1', '0u_username');

while($online_info = $link->fetch_array($online_query)) //THIS LINE THROWS THE ERROR


the simple_query function is:

function simple_query($fields, $table, $clause, $order)
    {
        global $link, $config;
        
        if(!empty($clause))
        {
            $clause = "WHERE $clause";
        }
        else
        {
            $clause = '';
        }    
            
        if(!empty($order))
        {
            $direction = $order[0];
            
            switch($direction)
            {
                case '0':
                $direction = 'ASC"';
                break;
                case '1':
                $direction = 'DESC';
                break;
            }
            
            $order = substr($order, 1, strlen($order));
            $order = "ORDER BY $order $direction";
        }
        
        $query = mysqli_query($this->link, "SELECT $fields
                FROM ".TBL_PREFIX."$table
                $clause
                $order");
        
        return $query;
    }

when i use a normal query instead of my simple_query function it works fine. it also worked fine before i made the database class. Where am i going wrong?

Hello,

i have one little problem and can't pass it. Problem is i need to call new sql query inside another query. Am trying to make accordion which will put result of first query($sql) like title and result of second query($sql2) like list of current item.
All time am getting error :

Quote

Warning: odbc_exec() [function.odbc-exec]: SQL error: [Microsoft][ODBC SQL Server Driver]Connection is busy with results for another hstmt, SQL state S1000 in SQLExecDirect in .....


I know reasone is because i use query inside query so am trying to figure is there any way to bypass it or make it work.

Example:
Code: [Select]
$sql="EXECUTE _PROCEDURE1 '".$date."',''.$code.";
$rs=odbc_exec($conn,$sql);

if (!$rs){exit("Error in SQL");}

while (odbc_fetch_row($rs)){
$id_number=odbc_result($rs,"ID");
$name=odbc_result($rs,"NAME");
echo $id_number.' - '.$name;

$sql2="EXECUTE _PROCEDURE2 '".$id_number."',''.$name.";
$name=odbc_exec($conn,$sql2);

while(odbc_fetch_row($popust)){
$detail = odbc_result($sql2,"DETAILS");
$detail2 = odbc_result($sql2,"DETAILS2");
$detail3 = odbc_result($sql2,"DETAILS3");
echo $detail.' - '.$detail2.' - '.$detail3;
}
}



I hope i explained it well.

Thanks.

Hi all, having a strange problem with my query
Its only returning some of my data, and in the format

User 1
<br />
<br />
User 2
<br />
<br />
<br />
<br />


Code: [Select]
$newmembers = "SELECT * FROM users WHERE linked_user IS NOT NULL ORDER BY datejoined LIMIT 6";

$nmresult = mysql_query($newmembers);

while($row = mysql_fetch_array($nmresult)){
echo $row['linked_user'];
echo "<br />";}

Hello all,
I am having this very frustrating issue, I am trying to print this query i got from my SQL table. However, If the query returns 10 [1,2,3,4,5,6,7,8,9] results it just prints 5 [2,4,6,8,10] . I have no idea what to do.

Code: [Select]

please help me

Here's my build a querty code...
Code: [Select]
$sql = "UPDATE $tablename SET
DIST_PART_NUM = '$dist_part_num',
DIST_PUB = '$dist_pub',
MFR_PART_NUM = '$mfr_part_num',
MFR_PUB = '$mfr_pub',
ITEM_DESC = '$item_desc',
ITEM_STD_DESC = '$item_std_desc',
ITEM_COPY = '$item_copy',
COST = '$cost',
GP_MULT = '$gp_mult',
ITEM_IMAGE = '$item_image',
ITEM_URL = '$item_url',
COUNTRY_OF_ORIG = '$country_of_orig',
CATEGORY_ID = '$category_id',
PICGROUP_KEY = '$picgroup_key',
UPC_CODE = '$upc_code',
LEADTIME = '$leadtime',
UNITS = '$units',
LENGTH = '$length',
WIDTH = '$width',
HEIGHT = '$height',
WEIGHT = '$weight',
FLAG_HAZARDOUS = '$flag_haz',
FLAG_LTL = '$flag_ltl',
FLAG_NON_RETURNABLE = '$flag_non',
CAMPAIGN_KEY = '$campaign_key', ";
foreach($atr as $key => $value)
{
$sql .= $value . "='" . addslashes($_POST[$value]) . "',";
}

$sql2 = rtrim($sql,",");

$sql2 .= " WHERE DIST_PART_NUM = '$partnumber' OR MFR_PART_NUM = '$partnumber'";

Now the query get's built 100% fine that's not the issue... my issue is that sine if the table fields are named something like #_of_shelves... and the # sign causes a MySQL error...
You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '' at line 26

How can i allow for the # sign, or any other character that can cause issues like () . , * ~ etc....

i tried encompassing the field name with single quotes 'fieldname' and with those slanted ones `tablename` but that did not help.

Any ideas?

Thanks!

So I wrote a question/answer script, and I am having issues with inputting symbols.
It works great it you only have letters, number, dots, commas, and likely other symbols.
However query fails every time you insert certain symbols.

Here is an error:
Quote

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '" ' ''' \ | / ) //    ')' at line 3


My test input was following:
Quote

' " ' ''' \ | / ) //   


I am not sure which symbol causes this, and I need help fixing this.

How do I go about this without stripping any symbols?

Maybe change table structure somehow?

Here is the error I get

ERROR: Could not execute query: INSERT INTO items (quickti, longti, desc, maincat, subcat1, subcat2, colour, size, style, price, stock, pic1, pic2, pic3, pic4, pic5, pic6, sold, saledate) VALUES ('quick', 'main title', 'description', 'Jewelry', 'Gemstones', 'Cubic Zirconia', 'Black', '50m', 'red', '1.50', '100', 'quick1', 'quick2', 'quick3', 'quick4', 'quick5', 'quick6', '0', '0'). You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'desc, maincat, subcat1, subcat2, colour, size, style, price, stock, pic1, pic2, ' at line 1

Here is the relevant code

$sql = "INSERT INTO items (quickti, longti, desc, maincat, subcat1, subcat2, colour, size, style, price, stock, pic1, pic2, pic3, pic4, pic5, pic6, sold, saledate)
         VALUES ('$quickheading', '$heading', '$content', '$cat1', '$cat2', '$cat3', '$colour', '$size', '$style', '$total', '$stock', '$quick1', '$quick2', '$quick3', '$quick4', '$quick5', '$quick6', '0', '0')";

if I remove desc and $content from the query, then it works.  desc is a text field.

I have following error when i try to enter my student info into the database.

I am having an error with this code

You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near ''name','email','password','profile') SET ('Sasural','kill@1234.com','kill','ANDK' at line 1

I am stuck with this for last 5hrs

I am getting an empty query error on this line

Code: [Select]
$mysql->query($insert);


here is my code
Code: [Select]
if(isset($_POST['submit'])){
$firstName = $_POST['firstName'];
$lastName = $_POST['lastName'];
$companyName = $_POST['companyName'];
$homePhone = $_POST['homePhone'];
$cellPhone = $_POST['cellPhone'];
$companyPhone = $_POST['companyPhone'];

//checking the values are filled
//echo $firstName. " " . $lastName . " " . $companyName . " " . $homePhone . " " . $cellPhone . " " . $companyPhone;

$insert = $mysql->query("INSERT INTO names('firstName','lastName','companyName'), phone('home','cell','company') values('$firstName','$lastName','$companyName','$homePhone','$cellPhone','$companyPhone'");

$mysql->query($insert);

if($insert){
echo "success";
}
else
{
mysql_error();
}

}


I got a connection to the database, I tested for it. I can't find the problem.
this is the error I get

Warning: mysqli::query() [mysqli.query]: Empty query in C:\wamp\www\test\formData.php on line 23

which is this line
Code: [Select]
$mysql->query($insert);

Unknown column 'Carmel' in 'where clause'
Warning: mysqli_fetch_assoc() expects parameter 1 to be mysqli_result, boolean given in /home/csi/public_html/resources/preview1920/sectional.php on line 19

 

Passing variable via the URL:

https://www.courtsideindiana.com/season-preview/19-20/sectional1920/?sectional=8&amp;school=Carmel

Sectional = 8

School = Carmel

Before I added the &school=Carmel, it was working, just echoing the total list of schools in the table.

$sectional = $_GET['sectional'];
$school = $_GET['school'];

echo $school;

// Query

$query = "SELECT * FROM a_schools WHERE sectional=".$sectional." AND school=" . $school ."";


$results = mysqli_query($con,$query);
echo mysqli_error($con);
while($row = mysqli_fetch_assoc($results)) {

echo $row['school'] . '<br>';

}

 

Hi all !,   I am stuck on the following piece of code which does not give an error nor does it give a result. ( i.e. it gives 0 num_rows which should be > 1).    If, however, I execute the query in phpmyadmin by simply substituting the values of $pp,$ll and $room_no in the query it gives the correct result.      Please can someone tell me what I may be doing wrong here.  Thanks !

	$fcon = mysqli_connect($db_host,$db_user,$db_pass,$db_database) or die('Unable to establish a DB connection');

				$pp = "(ms.level = 'Beginner' || ms.level = 'Intermediate')";	  
				$ll = 'ms.diff <= 7';
				$room_no = 4;

				$query = "SELECT md.Member_reg_id, md.fname, md.lname, md.email, md.cell, 
						ms.level, ms.diff, ms.score,  
						r.ID_Status 
						FROM register as r
						JOIN member_detail as md ON r.ID = md.Member_reg_id  
						JOIN memstatus as ms On r.ID = ms.ID  
						WHERE r.CENTERCODE = ? AND r.ID_Status ='A' AND ? AND ?
						ORDER by level, diff, score DESC";
		
				$stmt=$fcon->prepare($query);
				$stmt->bind_param('iss',$room_no,$pp,$ll);
				if(!$stmt->execute()) die('Failed to execute the query'.$fcon->error);
				else
				{
					echo "Executed";
					$stmt->bind_result($Member_reg_id,$fname,$lname,$email,$cell,$level,$diff                                               ,$score,$ID_Status);
					$numrows = $stmt->num_rows;
					$stmt->store_result();
//					echo $numrows;
					while($stmt->fetch())
					{
						echo "<br>".$fname.' '.$lname;
						echo "<br>".$level;
						echo "<br>".$diff;
						echo "<br>".$score;
						echo "<br>".$cell;
						echo "<br>".$email;
					}
				}

I'm trying to figure out some pagination on a left joined query, and not having any luck. The query seems to be pulling the entire database, so I went into the query's WHERE and added the table name "descriptors." Now I'm getting this error with the below query: Warning: mysql_fetch_array(): supplied argument is not a valid MySQL result resource in /data/21/2/40/160/2040975/user/2235577/htdocs/leafsearch4.php on line 35

also: Unknown column 'descriptors.leaf_shape' in 'where clause'
I thought this was syntax, but maybe I'm missing something.

Code: [Select]
$query = "SELECT COUNT(*) as num
                    FROM
                        descriptors
                    LEFT JOIN
                        plantae ON (descriptors.plant_id = plantae.plant_name)
                    WHERE
                        `descriptors.leaf_shape` LIKE '%$select1%'
                        AND `descriptors.leaf_venation` LIKE '%$select3%'
                        AND `descriptors.leaf_margin` LIKE '%$select4%'";

$total_pages = mysql_fetch_array(mysql_query($query));

Hi i have created a query where i want some columns to be retrieved. i get these 2 errors and i dont understand why.   Notice: Undefined variable: db Fatal error: Call to a member function query() on a non-object in      this is my query

function get_products_all() { 

$connect = get_connected_db();

try {
	  $results = $db->query("                                  ***** error on this line****
                SELECT  id, product, description, price, picc
                FROM products ORDER BY id DESC
				");
		
    } catch (Exception $e) {
        echo "Data could not be retrieved from the database.";
        exit;
    }

    $result = $results->fetchALL(PDO::FETCH_ASSOC);
	
	return $result;
}

what am i doing wrong?
