I wanted to get the sum of this column in my database and display it in home page. Here is the screen shot
http://bit.ly/1fJ7Cey
I use this code to save data on my Database
$timeanddate=$_POST['timeanddate'];
$time=$_POST['tst'];
$name=$_POST['name'];
$number=$_POST['number'];
$disposition=$_POST['disposition'];
$remarks=$_POST['remarks'];
$times=$_POST['timetoday'];
$dates=$_POST['datetoday'];
if(isset($_POST['submit']))
{
session_start();
$con=mysqli_connect("localhost","root","","hsncs_db");
// Check connection
if (mysqli_connect_errno())
{
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
$sql="INSERT INTO hsncs_tbl (id, name, number, call_disposition, remarks, time, date, time_duration, hsncs_user)
VALUES
('', '$_POST[name]', '$_POST[number]', '$_POST[disposition]', '$_POST[remarks]', '$_POST[timetoday]', '$_POST[datetoday]', '$_POST[tst]', '$_SESSION[fname]')";
if (!mysqli_query($con,$sql))
{
die('Error: ' . mysqli_error($con));
}
mysqli_close($con);
If this column time is of data type "time" in mysql then your query would be
SELECT SEC_TO_TIME( SUM( TIME_TO_SEC( `time_duration` ) ) ) AS timeSum FROM hsncs_tbl;

How should i solve this? there is not a row 1 and i cant insert or update data. Unique keys are indeed ip and uid in my table.
My code is as follows:
//Retrive listeners per reload
echo 'Data Höganäs <br>';
$sc="http://USER:PWD#SUB.SERVER.se:10000/admin.cgi?sid=1&mode=viewxml&page=3";
$xml2 = simplexml_load_file($sc);
foreach ($xml2->LISTENERS->LISTENER as $listener2) {
// Create connection
$conn = new mysqli($host, $user, $pwd, $db);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
$sql = " insert INTO hoganaskey
(ip, uid, tid, starttid, date)
VALUES
('$listener2->HOSTNAME', '$listener2->UID', '$listener2->CONNECTTIME', '$listener2->USERAGENT', '$starttid', '$date')
on duplicate key
update tid='$listener2->CONNECTTIME' ";
//$sql = "INSERT INTO hoganaskey (ip, uid, tid, ua, starttid, date) VALUES('$listener2->HOSTNAME', '$listener2->UID', '$listener2->CONNECTTIME', '$listener2->USERAGENT' '$starttid', '$date') ON DUPLICATE KEY UPDATE tid='$listener2->CONNECTTIME' ";
if ($conn->query($sql) === TRUE) {
echo "New record created successfully";
} else {
echo "Error: " . $sql . "<br>" . $conn->error;
}
$conn->close();
} //End foreach SHOUcast listener
Im returning this error in insert "Column count doesn't match value count at row 1".
In your insert query, you listed only 5 field names:
(ip, uid, tid, starttid, date)
but you are passing 6 values not 5:
('$listener2->HOSTNAME', '$listener2->UID', '$listener2->CONNECTTIME', '$listener2->USERAGENT', '$starttid', '$date')
I have a problem with my code. I have a table called "users" with an "id" field.I want to copy the id value to another table called "aircondition" . This is the code that inserts values into the aircondition table .The problem is that when I use this code I get 0 in the new id field instead of the user.id
<?php
$con=mysqli_connect("localhost","george","george123","my_db");
// Check connection
if (mysqli_connect_errno()) {
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
// escape variables for security
$acname = mysqli_real_escape_string($con, $_POST['ACName']);
$btu = mysqli_real_escape_string($con, $_POST['BTU']);
$space = mysqli_real_escape_string($con, $_POST['Space']);
$energyclass = mysqli_real_escape_string($con, $_POST['EnergyClass']);
$sql="INSERT INTO aircondition (id, ACName, BTU, Space, EnergyClass)
VALUES ('SELECT id
FROM users', '$acname', '$btu', '$space', '$energyclass')";
if (!mysqli_query($con,$sql)) {
die('Error: ' . mysqli_error($con));
}
header('location:aircondition.php');
mysqli_close($con);
?>
Use this query
INSERT INTO aircondition (id, ACName, BTU, Space, EnergyClass)
SELECT id, '$acname', '$btu', '$space', '$energyclass'
FROM users
When I use this code, I get one record for each id stored in the users table. Instead, I want to be able to insert only 1 record each time, the one that matches the logged users id.
if (mysqli_connect_errno()) {
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
// escape variables for security
$acname = mysqli_real_escape_string($con, $_POST['ACName']);
$btu = mysqli_real_escape_string($con, $_POST['BTU']);
$space = mysqli_real_escape_string($con, $_POST['Space']);
$energyclass = mysqli_real_escape_string($con, $_POST['EnergyClass']);
$sql="INSERT INTO aircondition (id, ACName, BTU, Space, EnergyClass)
SELECT id, '$acname', '$btu', '$space', '$energyclass'
FROM users";
if (!mysqli_query($con,$sql)) {
die('Error: ' . mysqli_error($con));
}
header('location:aircondition.php');
mysqli_close($con);
?>
You must have a where clause in your select statement
$sql="INSERT INTO aircondition (id, ACName, BTU, Space, EnergyClass)
SELECT id, '$acname', '$btu', '$space', '$energyclass'
FROM users WHERE usernamecolumn= currentusername ;
I want to modify my code so instead of just inserting a new row in the MySQL table, it can check to see if there is one with the same item number, and update it.
php code
<?php
$con=mysqli_connect("localhost","root","root","inventory");
// Check connection
if (mysqli_connect_errno($con))
{
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
$sql = "INSERT INTO `current stock` (ItemNumber, Stock)
VALUES
('".$_POST['ItemNumber']."', '".$_POST['Stock']."' )";
if (!mysqli_query($con,$sql))
{
die('Error: ' . mysqli_error($con));
}
echo "1 record added";
mysqli_close($con);
?>
You can use ON DUPLICATE KEY UPDATE syntax,
$sql = "
INSERT INTO `current stock` (ItemNumber, Stock)
VALUES ('$_POST[ItemNumber]', '$_POST[Stock]' )
ON DUPLICATE KEY UPDATE
Stock = '$_POST[Stock]'
";
ItemNumber should be primary/unique key in this case
I'm currently trying to write a script to migrate the database from a proprietary CMS system to a Joomla 1.6 database.
My code is throwing an error at the last "die". (Sorry, I've taught myself PHP along the way, I know I don't use the proper terminology for everything.)
<?php
$username="root";
$password="";
$database="DATABASE";
mysql_connect(localhost,$username,$password);
#mysql_select_db($database) or die( "Unable to select database");
$query="SELECT * FROM post3";
$result=mysql_query($query);
$num=mysql_num_rows($result);
mysql_close();
$i=0;
while ($i < $num) {
$postid=mysql_result($result,$i,"postid");
echo "$postid <br/>";
$poster=mysql_result($result,$i,"poster");
echo "$poster <br/>";
$department=mysql_result($result,$i,"department");
if($department=="LIFE"){
$department="12";}
elseif ($department=="NEWS"){
$department="11";}
elseif ($department=="SPORTS"){
$department="13";}
echo "$department <br/>";
$milestone=mysql_result($result,$i,"milestone");
echo "$milestone <br/>";
$date= date('Y-m-d H:i:s', $milestone);
echo "$date <br/>";
$title=mysql_result($result,$i,"title");
echo "$title <br/>";
$preview=mysql_result($result,$i,"preview");
if (empty($preview)) {
$preview=$title;
}
echo "$preview<br/>";
$alias=str_replace(" ","-", $title);
echo "$alias <br/>";
$bodytext=mysql_result($result,$i,"body_text");
echo "$bodytext <br/>";
$edited=mysql_result($result,$i,"edited");
echo "$edited <br/>";
$pop=mysql_result($result,$i,"pop");
echo "$pop <br/>";
echo "$i Records Copied<br/>";
$con = mysql_connect("localhost","root","");
if (!$con)
{
die('Could not connect: ' . mysql_error());
}
mysql_select_db("DATABASE", $con);
$sql="INSERT INTO conversion (id, title, alias, introtext, fulltext, state, sectionid, mask, catid, created, created_by, modified, modified_by, checked_out, checked_out_time, publish_up, publish_down, version, parentid, ordering, access, hits, featured, language)
VALUES
('$postid','$title','$alias','$preview','$bodytext','1','0','0','$department','$date','$poster','$date','$poster','0','0000-00-00 00:00:00','0000-00-00 00:00:00','0000-00-00 00:00:00','$edited','0','$i','1','$pop','0','*')";
if (!mysql_query($sql,$con))
{
die ("Query failed: " . mysql_error() . " Actual query: " . $sql);
}
echo "Success <br/>";
mysql_close($con);
$i++;
}
?>
It echos everything out fine, but throws this error:
Query failed: 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 'fulltext, state, sectionid, mask, catid, created, created_by, modified, modified' at line 1
Any ideas? Thank you!
fulltext is a MySQL reserved keyword. If you want to use it as a column name, you need to use backtickts, as in:
`fulltext`
"fulltext" is a MySQL reserved word, so either enclose it in backticks (e.g. `fulltext`) or use a different name for the field.
