MySQL Transaction last_insert_id
Can anyone tell me how to get the last inserted id when in transaction ?
I have to do inserts in several tables.
Problem is when inserting into one table my auto_increment id of the table should be used as a foreign key in the next table and so on.
I think when in transaction I cannot query for the last_insert_id with my existing connection, because it is not yet committed.
Is there a (standard) way to solve this problem ?
It depends what you mean by "standard". Standard to MySQL, you could use this:
SELECT LAST_INSERT_ID();
Some vendors provide driver-specific extensions to allow retrieval of such a value.
If you want a more portable solution then you could create a stored procedure to carry out the insert and have it return the ID as an out value.
There are other techniques, but I don't think there's a "standard" way to retrieve this value on insert, because this isn't a "standard" SQL feature in the first place.
Oh, and as far as I know most users couldn't care less about the duke dollars thing - they're not actually useful in any way.
Patience is a virtue.

Hi you all,
I have the following sql statement:
START TRANSACTION;
INSERT INTO mek_t_entity(name,dateCreated)VALUES('name',CURDATE());
INSERT INTO mek_t_user(idEntity_PK,favoriteBooks,favoriteFood,...)VALUES(LAST_INSERT_ID(),favoriteBooks,...);
COMMIT;Which I run using this code:
public String runStatement(String pStrStmt)
try
Statement objStmt = this.objConn.createStatement();
objStmt.execute(pStrStmt);
objStmt = null;
catch(SQLException ex)
return ex.getMessage();
return "";
}I haven't been able to run this transaction and I can't figure out what the problem is. I get a sql error, but the query runs just fine. Is there any problem whilst runnint transactions like this?
Any help is welcome,
Many thanks,

Can't get jdbc MySQL transactions to work
Hi
I'm trying to get a series of MySQL statements to work as a transaction but I can't get the transaction side to work.
I have the tables set up as InnoDB to support transactions.
My current code is written like this (from after the connection is opened). This method throws SQLException.
Statement statement = connection.createStatement();
String sql = "BEGIN;";
int i = statement.executeUpdate(sql);
// insert row into TABLE persons
sql = "INSERT INTO persons SET " +
"personID='" + p.getPersonID() + "', " +
"firstName='" + p.getFirstName() + "', " +
"lastName='" + p.getLastName() + "', " +
"emailAddress='" + p.getEmailAddress() + "', " +
"password='" + p.getPassword() + "', " +
"approvalRating='" + p.getApprovalRating() + "';";
i = statement.executeUpdate(sql);
// get the address object associated with p
Address a = p.getAddress();
// insert row into TABLE addresses
sql = "INSERT INTO addresses SET " +
"personID='" + a.getPersonID() + "', " +
"address1='" + a.getAddress1() + "', " +
"address2='" + a.getAddress2() + "', " +
"town='" + a.getTown() + "', " +
"city='" + a.getCity() + "', " +
"county='" + a.getCounty() + "', " +
"country='" + a.getCountry() + "', " +
"postcodeArea='" + a.getPostcodeArea() + "', " +
"postcode2='" + a.getPostcode2() + "', " +
"phoneHome='" + a.getPhoneHome() + "', " +
"phoneWork='" + a.getPhoneWork() + "', " +
"phoneMobile='" + a.getPhoneMobile() + "';";
i = statement.executeUpdate(sql);
sql = "COMMIT;";
int i = statement.executeUpdate(sql);When the SQLException is caught, I want to execute a ROLLBACK
I can't seem to get this to work. What am I doing wrong?1.) Which exact exception do you get and at what line?
2.) You should really use PreparedStatements and set the parameters there instead of building a dynamic SQL string, because that's greatly in danger of beeing attacked with a SQL injection attack. See http://en.wikipedia.org/wiki/SQL_injection for details.
3.) You don't need to execute "COMMIT;" as a SQL command, there's connection.commit() for this (make sure that auto-commit is off, using connection.setAutoCommit() if necessary).
Edit: 4.) You don't need to do "BEGIN" as well (what gave you the idea, by the way?) -
MySQL - Transactions without locks?
Hi , I am using the native transaction support of mysql innodb ( setautocommit(false) etc etc).
I also want to have multiple connections to the database which are able to update the same rows etc. - -now the error I'm getting is 'lock wait timeout'.
Probably this forum is not the exact place for this question, but is there any way of unlocking the rows? ie i start a transaction, insert some row, then want another connection/transaction to be able to update that row - and then commit or rollback either transaction I feel like. Timeout is not a solution as i want overlapping transactions.
This might sound mad/bad but please don't reply telling me its dangerous etc etc
Any help much appreciated,

As far as I know, no database does overlapping transactions. (I suspect that either it is not feasible or it would have a huge performance impact. Or both.)
So your choice is either to live with the locks or stop using explicit transactions and write one row at a time. -
MySQL transactions are not enabled
Hi,
We cannot connect to a MySQL 4.0 database with dg4odbc, although it previously connected ok when using hsodbc on 10g (we are now on 11g R2). Unfortunately, the MySQL database is part of a commerical software application, so we cannot make any major changes to the MySQL database or upgrade it to a more recent version.
The error we get when trying to connect to the dblink is [MySQL][ODBC 3.51 Driver]Transactions are not enabled, option value SQL_AUTOCOMMIT_OFF changed to SQL_AUTOCOMMIT_ON {01S02,NativeErr = 502}.
Is there anyway to get past this error message. We are using the MySQL 3.5.27 ODBC connector. Both Oracle and MySQL are on Windows Server 2008 R2.
ThanksHi,
DG4ODBC has different ODBC driver requirements from the earlier HSODBC. These are listed in the documentation -
Oracle® Database Gateway for ODBC
User’s Guide
11g Release 1 (11.1)
ODBC Connectivity Requirements
There have been some issues with DG4ODBC and the 3.5 driver accessing MySQL v4 so do you know if the MYSQL v5 drivers can be used with MySQL v4 ? This may be an option if possible.

Mysql, transactions and connections
Hi,
I have two problems:
1. I am using mysql 3.23 and JBuilder 6 and I would like to use transactions.
I created a database and a table InnoDb and when I try from my application to setautocommit(false) I get the following error:
See com.borland.dx.dataset.DataSetException error code: BASE+66
com.borland.dx.dataset.DataSetException: Cannot disable AUTO_COMMIT
I tried lots of things in the mysql server and in my application and I don't know wether it's a configuration of the server, something I need to set first in the WinMySqlAdmin or something I have to do in my application.
I would really use some help.. If anyone could also provide a small example please..
2. It's also related to Mysql
I have a server that opens a connection to the database. I want to know what I have to set in the mysql server so that the connection is not lost if the server is not active a long time.. I thought that if I set the interactive_timeout and the wait_timeout at a high level the problems would be solved but when I did some testing by setting the values to 30 seconds the connection persisted. Does anyone know why?
Please help
Thanks"MySql does not support transactions" is correct.
Basically there are no commit or rollback statements
available in MySql. This is I am talking about
version 3.2.3 I believe. I have used it long back.incorrect.
if you use the default myISAM tables than there is no transaction support. however, if you use INNODB then there is transaction support available in versions of 3 etc. for sure.
however, you need a driver that knows this and supports this. i believe the newer versions of the mysql driver support them i know the older org.gjt.mm driver does NOT.
what driver are you using? some borland one? look at the support there. -
Once again: Does MySQL allow multiple querys in one database transaction???
Hello to ALL!!!
The problem is:
I'm trying to make simple query (database: "myDB" (engine:
myisam/innodb - doesn't mater) with one table: "Info" with two
columns: "Id" (autoinc), "info_c" (varchar):
<cfif structkeyexists (form, "name")>
<cfquery datasource="myDB" name="qDB" >
INSERT into Info (info_c)
VALUES ('#form.name#');
SELECT @@identity AS Id
</cfquery>
</cfif>
<cfform>
<cfinput type="text" name="name">
<cfinput type="submit" name="submit">
</cfform>
BUT after "Submit" I get:
Error Executing Database Query.
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 '; select @@identity as Id' at line 2
Please, tell me WHY???
I have:
MySQL
Server information:
MySQL version: MySQL 5.1.25-rc-community via TCP/IP
Clent Information:
Version: MySQL client version 5.1.11
Coldfusion Version Information:
Version 8,0,0,176276
Great THANKS for your answers!!!> SELECT @@identity AS Id
AFAIK, MySQL uses LAST_INSERT_ID(). @@IDENTITY is MS SQL
specific. Though SCOPE_IDENITY() is recommended over @@IDENTITY.
What version of CF are you using? ColdFusion supports the
"result" attribute, which will return the ID value for simple
inserts. See the documentation for details
http://livedocs.adobe.com/coldfusion/8/Tags_p-q_17.html
> Do JDBC drivers for MySQL prohibit the use of multiple
queries
> in a single database transaction???
For security purposes this is disabled by default. To enable
it you must modify your datasource url

"com.mysql.jdbc.PacketTooBigException": Help needed urgently
hi,
I am using mm.mysql j/connector ver 3.0.6 and MYSQL server version 4.0.
Max_allowed packet= 8MB at the server side
I am getting PacketTooBigException when i am trying to update a particular column.
What should i do.
Any help will be greatly appreciated!!!the driver uses a 64 k max packet size by default. it is supposed to change this as neccessary upon connection but perhaps that is failing?
below is the 3.0.7 connection code that i have slightly modified for you so that it prints out the connection properties after they have been initialized so that you can see what they are.
try it out and i hope you find this helpful.

Anyone know how to insert to multiple tables on Dreamweaver?
Hey everyone,
I'm a bit of a newbie at PHP and am trying to create my first "dynamic" site. I have a registration table with fields idNo (primary key & auto-increment), username, password, email. I also have another table called profile with fields idNo, location, musicalInfluences, aboutMe etc. All of these fields except idNo have the default value of "update." What I want to be able to do is add a second insert statement to the user registration behaviour so that I can have the idNo number added to the profile tables as well as the registration table. That way the registration and profile are linked by idNo and I can create a record-set do automatically populate the profile table on my profile page when the user logs in. All of the different profile traits would say "update" and I can then use an update server behaviour for the user to update there profile.
I might be approaching this the wrong way so I'm open to suggestions on how to create a user login and linked profile page. One thing I could not work out was how, when the user clicks login with the correct credentials, I was supposed to separate a first time user, directed to the create profile page, from a user who has already created a profile page and just wants to see it. The only way I could think of was by using the default method explained before and then having an update page. Sorry if that was a bit of a waffle. Here is my code. Any help would be much appreciated!!
This is the script that I have included on my registration page. I just extracted the php and used an include to keep the html page tidy.
<?php require_once('Connections/soundstorm.php'); ?>
<?php
if (!function_exists("GetSQLValueString")) {
function GetSQLValueString($theValue, $theType, $theDefinedValue = "", $theNotDefinedValue = "")

$theValue = get_magic_quotes_gpc() ? stripslashes($theValue) : $theValue;
$theValue = function_exists("mysql_real_escape_string") ? mysql_real_escape_string($theValue) : mysql_escape_string($theValue);
switch ($theType) {
case "text":
$theValue = ($theValue != "") ? "'" . $theValue . "'" : "NULL";
break;

$theValue = ($theValue != "") ? intval($theValue) : "NULL";

$theValue = ($theValue != "") ? doubleval($theValue) : "NULL";
break;

$theValue = ($theValue != "") ? "'" . $theValue . "'" : "NULL";
break;

$theValue = ($theValue != "") ? $theDefinedValue : $theNotDefinedValue;
break;
return $theValue;

$MM_dupKeyRedirect="usernameExists.php";
$loginUsername = $_POST['username'];
$LoginRS__query = sprintf("SELECT username FROM registration WHERE username=%s", GetSQLValueString($loginUsername, "text"));
mysql_select_db($database_soundstorm, $soundstorm);
$LoginRS=mysql_query($LoginRS__query, $soundstorm) or die(mysql_error());
$loginFoundUser = mysql_num_rows($LoginRS);
//if there is a row in the database, the username was found - can not add the requested username
if($loginFoundUser){
$MM_qsChar = "?";
//append the username to the redirect page
if (substr_count($MM_dupKeyRedirect,"?") >=1) $MM_qsChar = "&";
$MM_dupKeyRedirect = $MM_dupKeyRedirect . $MM_qsChar ."requsername=".$loginUsername;
header ("Location: $MM_dupKeyRedirect");
exit;
$editFormAction = $_SERVER['PHP_SELF'];
if (isset($_SERVER['QUERY_STRING'])) {
$editFormAction .= "?" . htmlentities($_SERVER['QUERY_STRING']);
if ((isset($_POST["MM_insert"])) && ($_POST["MM_insert"] == "registerForm")) {
$insertSQL = sprintf("INSERT INTO registration (username, password, email) VALUES (%s, %s, %s)",
GetSQLValueString($_POST['username'], "text"),

if (isset($_SERVER['QUERY_STRING'])) {
$insertGoTo .= (strpos($insertGoTo, '?')) ? "&" : "?";
$insertGoTo .= $_SERVER['QUERY_STRING'];
header(sprintf("Location: %s", $insertGoTo));
?>you can use a trigger in mysql. this trigger is for new records in your registration table. you can use mysql's last_insert_id() to get the last record inserted. just search for mysql triggers to get more info. note that this is not php code, it is mysql.

My merchant account company is raising my rates and making me buy new software. I am looking for a different solution and anyone familiar with credit card processing may be able to give me some good advice.
Up until now, I used software that I installed on my computer that would enable me to process transactions over the Internet. My question is: When someone gives me a credit card number, can I process credit cards using a secure page coded with php? I have a dedicated IP, I can get an SSL certificate, and I can sign up with a credit card gateway like Authorize.net. Why would I need a merchant account (who will charge me a percentage of everything I make)?
There are a number of good php credit card processing scripts available. Can I bypass the merchant account company using a php page that will process my credit cards?Hi John
The php code and the process are tightly related when it comes to processing your own credit card transactions and then passing them on for payment authorisation.
All the items must be done on secure server section of site, and will depend on if you wish to create a user account or not, this is for the non-user account
Customer fills in Their details on order form, (Name address, credit card info, etc.)
Details stored in temp database for such transactions via a php back-end script, using encryption for credit card details.
Customer is then shown a confirm page, with the details of the order, only the last four digits of the credit card number are shown.
If the user clicks 'place order' another back-end php script transfers the details to a permanent database and send the details for transaction conformation to your credit card authorization gateway.
Payment status sent to another back-end processing script for completion of transaction, this is often done via ipn or similar system.
Confirm payment and details are displayed to the customer, along with your transaction number, (this one may be omitted) and customer order no.
That's basically the procedure, the scripts can be on the same page using functions, or separate scripts if using procedural code. There are obviously many variations on this procedure but this one is probably the most common.
The use of 'secure pay' adds another two steps to this procedure in that the customer is sent to their card providers site for a second step to the authentication. There they must give a user name and password, (previously agreed and confirmed, if not it gets more complicated) in order to confirm that they are the card holder, before the actual card transaction can continue. To give you some idea of the complexity of the 'secure pay' set-up, the general extra cost can range anywhere between $1000 and $3000, (depending if done within web site development budget, or as an extra) converting from U/K £ to $.
BTW, The secure pay is normally used by bank card processing, these used to be know as 'Merchant Accounts', but paypal and others started using this term for their accounts which complicated the issue, the bank processing is what I am referring to with this term, and the fact that visa and mastercard use a different processing procedure is why I say, 'avoid'.
(Sorry if this explanation is a little long, but once you go outside the standard card processing, it does get more complex).
I came across a web site (hotscripts.com) and found some PHP scripts
that
process credit cards.
Unless you are happy adding extra security checks to the code to validate your site is the one using it, try to avoid any scripts that are 'in the public domain'. This is not said with any prejudice or doubt regarding the code, more that once you process your own credit cards you become completely responsible, (legally) for any fraud or misuse that results from your scripts/site.
One other item is that I would recommend using PHP:PDO with MySQL transactions and bound-parameters/stored procedures for this, mainly because they adds extra levels of security and redundancy to the procedure, which is not possible using the standard php/mysql code.
Hope this clears a few details up.

Is JBoss a right solution for me?
Hi,
I want to develop web services using Apache XML-RPC and standard Java Objects, no EJB's. I require "Connection Pooling" feature available in JBoss. I am planning to use MySQL Transactions available in MySQL Connector /J and caching in MySQL using query-cache directive in my.cnf. I should be able to configure Virtual Hosts in the Application server to deploy different web services in different url's. I am not able to decide whether JBoss is a right Application server for my problem. If yes, can I disable EJB from JBoss. If I don't disable EJB from JBoss, is it an overhead. Please advise me.
Thanks a lot.If you don't need EJBs, you can go with Tomcat as your servlet/JSP engine. It does connection pooling.

Hello,
Are there anybody using sip ver 2.1?
We are going to upgrade from 2.0 to 2.1
but see that changing the IP address of the SIP requires uninstall all SIP and install again with a new IP !
However in SIP 2.0 we can change the IP address
of the SIP as usual.
Is there any way to change the IP of sip 2.1
without uninstall the whole server ? :-)
Regards,
HAThere are several ip's you have to change.
First you have to change the ip addr of the physical interfaces and then you can change the addresses in the sipd.conf file.
This file contains the ip's of the SPS used in the SIP messages and also the addresses used in the MySQL transactions. -
PSTN users VM not delivered to subscriber
Hi ,
I am facing an strange issue in cisco unity 5.0 with Exchange 2003 and exchange 2010.
Whenever an local ip phone user calls and leaves a voice mail to another user, the message will get delivered to subscriber mailbox successfully.
But if any PSTN user calls the IP Phone user and leaves a voice mail it does not get delivered to subscriber mail box , instead VM moves to "UnityMTA/failed" folder.
In event viewer i get logs of CiscoUnity_UMR error.

I am trying to pipe an email into php script using the aliase file in postfix. My test script looks like this:
<?php
$fd = fopen("php://stdin", "r");
$email = "";
while (!feof($fd)) {
$email .= fread($fd, 1024);
fclose($fd);
if($fd){
$data = "Mail received\n";
$fp = fopen("result.txt", "w");
fwrite($fp, $data);
fclose($fp);
?>
The script works from the command line if I issue something like 'cat <email #> | php script.php'. I have this line in my aliases file:
testuser: | "/usr/bin/php /Volumes/path/to/script.php"
When I send a test email I receive an 'Undelivered Mail Returned to Sender' reply with the following line:
'Command died with status 1: "/usr/bin/php /Volumes/path/to/script.php". Command output: Could not open input file: /Volumes/path/to/script.php'
I have found similar problems like this on the web but no one seems to find an answer. I have tried various permissions and owners, I have also tried various ways to enter in the alias line, making sure to issue 'sudo newaliases' after each change. Is it the script, Postfix or something else?
Thanks,
NickIm doing the same thing with no trouble... a few slight differences...
1. I only pipe to the path of the script, not the php executable:
quaynotifydaemon: |"/usr/local/bin/quaynotify.php"
2. I don't use fwrite in my script:
// Read standard input
$fd = fopen("php://stdin", "r");
$email = "";
while (!feof($fd)) {
$email .= fread($fd, 1024);
fclose($fd);
After that, is the meat of my script, which does some mysql transactions and some other stuff.
Also, FYI the privileges of my php file are 755:
$ls -al /usr/local/bin/quaynotify.php
-rwxr-xr-x 1 admin wheel 10586 Jun 4 10:52 /usr/local/bin/quaynotify.php -
