I have 3 tables.
Tables
When I insert data to the ekf_parag I do it like this:
$ekfonites = $_POST['ekfonites'];
foreach ($ekfonites as $ekfonitis) {
$parago = $db_con->prepare('SELECT MAX(id) FROM paragoges');
$parago->execute();
$paragoges_id = $parago->fetchColumn();
$ekf = $db_con->prepare('INSERT INTO ekf_parag(id, paragoges_id, ekf_id, ekfonisan) VALUES("", :paragoges_id, :ekfonitis, 0)');
$ekf->bindParam(':ekfonitis', $ekfonitis);
$ekf->bindParam(':paragoges_id', $paragoges_id);
$ekf->execute();
}
But when I try to update the table I don't know how to trigger the id from table paragoges. Because it's important (I think) to put the update query inside the foreach, cause there is not only one value in the $ekfonites variable.
Please help me!

Bit new to MYSQL and PHP - I have the following code that will create a new record in multiple tables that I have setup however I need to merge the following code together somehow as it creates separate rows instead of one record
$sql .=("INSERT INTO orders (customer_id) SELECT customer_id FROM
customer_details;");
foreach($result as $item){
$mysql_desc = $item['product_description'];
$mysql_mode = $item['delivery_mode'];
$mysql_cost = $item['course_cost'];
$sql .=("INSERT INTO orders(product_description, delivery_mode, course_cost) VALUES('$mysql_desc', '$mysql_mode', '$mysql_cost');");
}
The result I'm getting:
Based on your data I assume that you want to insert the customer id and the values from php into the same record. In this case you need to combine them into the same insert ... select ... statement:
$sql .=("INSERT INTO orders(customer_id, product_description, delivery_mode, course_cost) select customer_id, '$mysql_desc', '$mysql_mode', '$mysql_cost' from customer_details;");
Couple of things to note:
This insert ... select ... statement will insert the same records for all customers in the customer details table. I'm not sure if this is your ultimate goal.
Pls consider the advices made in the comments regarding the old mysql API and the use of prepared statements.
To put this more into what I would expect to happen, something along the lines of - prepare statement, then loop through each item and add in new row...
$insert = $connection->prepare("INSERT INTO orders (customer_id,product_description, delivery_mode, course_cost)
VALUES (?,?,?,?)");
foreach($result as $item){
$customerID = 1; // Have to ensure this is what your after
$mysql_desc = $item['product_description'];
$mysql_mode = $item['delivery_mode'];
$mysql_cost = $item['course_cost'];
$insert->execute([customerID,mysql_desc,mysql_mode,mysql_cost]);
}
I want to create columns in a MySQL table and insert data into them. I already have some data inside of the table, I would like to add more. I am not sure how I would go about adding the other data. If someone could help me out, I would greatly appreciate it. Thanks.
My Source code looks like this:
if($is_array($asinXML){
foreach($asinXML as $asinXml){
$asinXmlLoaded = simplexml_load_file($asinXml);
foreach($asinXml->GetLowestOfferListingsForASINResult as $asinItem){
if(isset($asinItem['ASIN'])){
$asinValue = $asinItem['ASIN'];
} else {
$asinValue = '';
}
$asinErrorFound = 'Success' != $asinItem->attributes()->status;
if($asinErrorFound = TRUE){
$asinErrorFoundVal = 'Yes';
} else {
$asinErrorFoundVal = '';
}
if($asinErrorFoundVal == ''){
if(isset($asinItem->Product->LowestOfferListing->NumberOfOfferListingsConsidered){
$numberOfSellers = $asinItem->Product->LowestOfferListings->LowestOfferListing->NumberOfOfferListingsConsidered;
} else {
$numberOfSellers = '';
}
My Sql table looks something like this so far :
UPC ASIN SalesRank
Value Value1 Value2
I need to be able to insert a insert another column, then populate the column with information that corresponds to the ASIN Value. If that doesn't make sense, comment and i will elaborate. Thanks.
You can add a column (or columns) using ALTER TABLE statement. e.g.
ALTER TABLE mytable ADD my_new_col INT COMMENT 'my new column' ;
If you want to initialize that column on all of the rows that are already in the table, you can populate it with the value from another column on the row with an UPDATE statement:
UPDATE mytable SET my_new_col = some_old_col ;
If you just want to add a new row to the table, you can use the INSERT statement:
INSERT INTO mytable (my_new_col) VALUES (42);
you can ADD a calculated Column with the desired value.
If ASIN is numeric and you want to add taxes
ALTER TABLE myTable ADD MyNewColumn AS (ASIN * 1.08)
i want to get datas from a mySQL table and want to insert every row (that my query get) into another table.
With following code i get my Datas:
$cart = new Dbconn();
$query = new Dbconn();
if ($cart->pdo()) {
$cart->stmt("SELECT id, product FROM cart WHERE uid =:uid");
$cart->bindParam(':uid', Session::get('uid'));
$cart->exe();
}
After i get the data i want to insert it, with a while loop
while ($rowPay = $cart->fetch()) {
if ($query->pdo()) {
$query->stmt('INSERT INTO orders (products_id, order_id) VALUES(:uid, :products)');
$query->bindParam(':user_id', Session::get('uid'));
$query->bindParam(':products', $rowPay['product']);
$query->exe();
}
}
He get all Datas but insert only the first entry. Where is my mistake?
Greetings
If it insert only the first entry, then there is a problem with the parameters you try to insert.
You probably try to insert several rows with the same primary key.
I need to know where is the primary key in each table in order to help you more.
$payCart->fetch() fetches single row and $payCart->fetchAll() fetches all rows.
Try as this
while ($rowPay = $payCart->fetchAll(PDO::FETCH_ASSOC)) {
if ($query->pdo()) {
$query->stmt('INSERT INTO orders'
.'(products_id, order_id)'
.'VALUES(:uid, :products)');
$query->bindParam(':user_id', Session::get('uid'));
$query->bindParam(':products', $rowPay['product']);
$query->exe();}}
I have the following two tables
Table player:
player_id (int)(primary)
player_name (varchar)
player_report_count (int)
Table report:
report_id (int)(primary)
player_id
report_description
report_location
Firstly I ask the user for the player_name and insert it into the player database. From here the player is given an id.
Then I tried to grab the value of the players report count and increment the current value by one (which isn't working).
This is followed by grabbing the playerId from the player table and then inserting into the corresponding column from the report table (also does not work).
When I insert some values into the database, the names, description and report are added to the database however the playerID remains at 0 for all entries and the player_report_count remains at a consistent 0.
What is the correct way to make these two features function? And also is there a more efficient way of doing this?
<?php
$records = array();
if(!empty($_POST)){
if(isset($_POST['player_name'],
$_POST['report_description'],
$_POST['report_location'])){
$player_name = trim($_POST['player_name']);
$report_description = trim($_POST['report_description']);
$report_location = trim($_POST['report_location']);
if(!empty($player_name) && !empty($report_description) && !empty($report_location)){
$insertPlayer = $db->prepare("
INSERT INTO player (player_name)
VALUES (?)
");
$insertPlayer->bind_param('s', $player_name);
$reportCount = $db->query("
UPDATE player
SET player_report_count = player_report_count + 1
WHERE
player_name = $player_name
");
$getPlayerId = $db->query("
SELECT player_id
FROM player
WHERE player_name = $player_name
");
$insertReport = $db->prepare("
INSERT INTO report (player_id, report_description, report_location)
VALUES (?, ?, ?)
");
$insertReport->bind_param('iss', $getPlayerId, $report_description, $report_location);
if($insertPlayer->execute()
&& $insertReport->execute()
){
header('Location: insert.php');
die();
}
}
}
Main issue here is you are getting player details before inserting it. $getPlayerId will return empty result always.
Please follow the order as follows.
Insert player details in to player table and get payerid with mysql_insert_id. After binding you need to execute to insert details to the table.
Then bind and execute insert report .
Then update the player table by incrementing report count with playerid which you got in step 1.
Note : use transactions when inserting multiple table. This will help you to rollback if any insert fails.
MySQL Query will return result object. Refer it from here https://stackoverflow.com/a/13791544/3045153
I hope it will help you
If you need to catch the ID of the last insterted player, This is the function you need if you're using PDO or if it's a custom Mysql Class, you need the return value of mysql_insert_id() (or mysqli_insert_id()) and then directly use it in the next INSERT INTO statement
I'm new to php. So, please forgive me if this seems like a dumb question.
Say i have a MySQL insert statement insert into table (a,b) values (1,2),(3,4),(5,6). table 'table' has a auto increment field called 'id'.
how can I retrieve all the ids created by the insert statement above?
It will be great if i get an example that uses mysqli.
You can't. I would suggest that you maintain your own ids (using guid or your own auto-increment table) and use it when you insert into the table.
But it's possible to get the auto-increment value for the last inserted using LAST_INSERT_ID():
http://dev.mysql.com/doc/refman/5.0/en/getting-unique-id.html
AngeDeLaMort's answer is almost right. Certainly, the most appropriate way to deal with the problem is to insert one row at a time and poll the insert_id or generate the sequence elsewhere (which has additional benefits in terms of scalability).
I'd advise strongly against trying to determine the last insert_id and comparing this the most recent insert_id after the insert - there's just too may ways this will fail.
But...an alternative approach would be:
....
"INSERT INTO destn (id, data, other, trans_ref)
SELECT id, data, other, connection_id() FROM source";
....
"SELECT id FROM destn WHERE trans_ref=connection_id()";
....
"UPDATE destn SET trans_ref=NULL where trans_ref=connection_id()";
The second query will return the ids generated (note that this assumes that you use the same connection for all 3 queries). The third query is necessary because connection ids to go back into the pool when you disconnect (i.e. are reused).
C.
In some cases, if you have another identifier of sort such as a UserID, you could filter your query by UniqueID's greater than or equal to mysql_insert_id(), limit by the number of affected rows and only display those by the user. This would really only work inside of a transaction.
$SQL = "INSERT INTO Table
(UserID, Data)
VALUES
(1,'Foo'),
(1,'Bar'),
(1,'FooBar')";
$Result = mysql_query($SQL);
$LastID = mysql_insert_id();
$RowsAffected = mysql_affected_rows();
$IDSQL = "SELECT RecordID
FROM Table
WHERE UserID = 1
AND RecordID >= '$LastID'
LIMIT '$RowsAffected'";
$IDResult = mysql_query($IDSQL);
as a follow up to AngeDeLaMort:
You could seperate your inserts and do it something like this:
$data = array (
array(1,2),
array(3,4),
array(5,6)
);
$ids = array();
foreach ($data as $item) {
$sql = 'insert into table (a,b) values ('.$item[0].','.$item[1].')';
mysql_query ($sql);
$id[] = mysql_insert_id();
}
Now all your new id's are in the $id array.
Maybe I can do this
$insert = "insert into table (a,b) values (1,2),(3,4),(5,6)";
$mysqli->query($insert);
$rows_to_be_inserted=3;
$inserted_id = $mysqli->insert_id // gives me the id of the first row in my list
$last_row_id = ($inserted_id+$rows_to_be_inserted)-1;
$mysql->query("select * from table where id between $inserted_id and $last_row_id");
what to you guys say?
