MySQL Date Question

I have two DATETIME columns in a table. Is it possible to get the difference between the two dates and then format the output as H:M P?
I've been trying to get this to work for a while... but now I'm not even sure it's possible.

I have two DATETIME columns in a table. Is it possible
to get the difference between the two dates and then
format the output as H:M P?A MySql-query along these lines might just do the job:
SELECT SEC_TO_TIME(UNIX_TIMESTAMP(yourDATETIME_1) - UNIX_TIMESTAMP(yourDATETIME2)) AS TimeDifference FROM yourTable;
It gives you the time difference (conveniently availaible as TimeDifference) in a HH:MM:SS format. Additionally, you can use the TIME_FORMAT() function to convert it to a more suitable format, e.g.
SELECT TIME_FORMAT(SEC_TO_TIME(UNIX_TIMESTAMP(yourDATETIME_1) - UNIX_TIMESTAMP(yourDATETIME2)), "%H:%i") AS TimeDifference FROM yourTable;
- giving you the hours and minutes. For details, see http://www.mysql.com/doc/en/Date_and_time_functions.html
Maybe all of this isn't exactly what you were looking for, but at least it should give you an idea of the possibilities and something to work from. Hopefully!

JPA with MySQL-Data-Source

Hello Forum,
I have a question regarding usage of a MySQL-Data-Source in combination with JPA
on the SAP NetWeaver Application Server, Java EE 5 Edition.
I have setup a custom datasource like explained in paper:
"Working with Database Tables, DataSources and JMS Resources"
- registered the database driver via telnet (Using mysql-connector-java-5.0.3-bin.jar)
- created the data-sources.xml file underneath the META-INF dir of the EAR project
[code]
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE data-sources SYSTEM "data-sources.dtd" >
<data-sources>
<data-source>
    <data-source-name>titan_cruises_ds</data-source-name>
    <driver-name>mysql-connector-java-5.0.3-bin.jar</driver-name>
     <init-connections>1</init-connections>
     <max-connections>10</max-connections>
     <max-time-to-wait-connection>60</max-time-to-wait-connection>
     <expiration-control>
          <connection-lifetime>600</connection-lifetime>
          <run-cleanup-thread>60</run-cleanup-thread>
     </expiration-control>
     <sql-engine>native_sql</sql-engine>
    <jdbc-1.x>
      <driver-class-name>com.mysql.jdbc.Driver</driver-class-name>
      <url>jdbc:mysql://ourHost.internal.com:3306/practise_titan_cruises</url>
      <user-name>myUser</user-name>
      <password>myPass</password>
    </jdbc-1.x>
</data-source>
</data-sources>
[/code]
After that I manually created the persistence.xml underneath the META-INF dir of the EJB project.
[code]
<persistence xmlns="http://java.sun.com/xml/ns/persistence" version="1.0">
     <persistence-unit name="titan_cruises_pu">
          <jta-data-source>titan_cruises_ds</jta-data-source>
     </persistence-unit>
</persistence>
[/code]
After that I created the Entity named "Cabin" and the corresponding table within the db.
Entity code:
[code]
package de.collogia.beans.pojo.ship;
import java.io.IOException;
import java.io.Serializable;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import javax.persistence.Table;
This persisted POJO class models the cabin data.
<p>
In this class persistence annotations are placed on the getter methods
of the attributes. This tells the persistence manager to access them
via the corresponding get- and set-Methods.</p>
(Unfortunately this does not work on NetWeaver and I had to place them
on field level aggain...)

After that I created the TravelAgentBean, a Stateless Session Bean, implementing
a remote interface that allows construction and persisting of new Cabin objects:

After that I created a Controller class containing a main method that looks up the remote
interface of the TravelAgentBena like explained in document "Accessing Enterprise JavaBeans Using JNDI
in SAP NetWeaver Application Server, Java EE 5 Edition" written by Validimir Pavlov of SAP NetWeaver
development team.
Unfortunately I receive an Exception after invoking the createCabin(...) method.
On the console of the NWDS I receive:
[code]

But if I look at the log file located in "C:\NWAS_JAVAEE5\JP1\JC00\j2ee\cluster\server0\log\defaultTrace.0.trc"
I see the real reason is:

Am I thinking in the right direction to blame attribute [code]<sql-engine>native_sql</sql-engine>[/code]
of file data-sources.xml for the beaviour? Are there any other argument options than native_sql?

Here we strictly implemented the checks according to the requirements of the JPA specification. Technically, we could do with private constructors as well. But the JPA specifications requires the constructor to be protected to allow a JPA implementation to subclass entities if needed.

For the same reason, your entities should not be final. Are we missing a check here ?

No, unfortunately, there is no comparable option in SAP JPA (yet). We understand that there is a need for forward mapping. We would have liked to delegate this task to the JPA design time (i.e. Dali). However, we had to discover that Dali does not perform this task properly and we can't recommend using it any more.
Consequently, there is no automatic schema generation in SAP JPA 1.0.

With Hibernate Entity Manager, the id generation strategy in use with GenerationType.AUTO depends on the database dialect. This means that depending on the database dialect, IDENTITY columns, SEQUENCES or generator tables (TableHiLo) are required. As Hibernate has the before mentioned schema generation property this fact can be hidden to the user.
In SAP JPA, we are always using a table generator if GenerationType.AUTO is used. This allows for better portability across databases. It requires the table TMP_SEQUENCE. As we unfortunately do not have a schema generation capability, the user must create this table.

Error Message in Terminal: unknown variable 'datadir=/usr/local/mysql/data'

Hello,
I'm on a Mac Pro Quad Core Intel Xeon (64-bit) using OS 10.6.4. I have mysqlnd 5.0.5-dev - 081106 - $Revision: 289630 $ and PHP Version 5.3.1.
I have also installed phpMyAdmin 3.3.1 and have set up the relations tables in a pmadb within mysql; created a new database with tables; and created some new users. I am able to access and use mysql via phpMyAdmin.
But now I am unable to login to mysql via the Terminal command:
mysql -u root -p
which now returns an error message of:
/usr/local/mysql/bin/mysql: unknown variable 'datadir=/usr/local/mysql/data'
my.cnf file reads:
[mysqld]
datadir=/usr/local/mysql/data
socket=/var/mysql/mysql.sock
#skip-grant-tables=1
[client]
datadir=/usr/local/mysql/data
socket=/var/lib/mysql/mysql.sock
and I can see the data directory in that location when using the Terminal.
My questions:
1. Is this related to anything I have done in setting up phpMyAdmin (tables, users)?
2. Is this a permissions problem with the directory named /usr/local/mysql/data?
Currently, the permissions and ownership are this:
drwxr-x--- 11 _mysql wheel 374 Jun 29 12:10 data
3. Is this a problem from upgrading to 10.6.4 recently?
4. Is this a my.cnf problem?
I would really like to be able to do things in the Terminal with mysql in addition to using phpMyAdmin.
Many thanks for any help on this.
Best,
Shelley

Thanks for your suggestion, etresoft, but this was not helpful, I'm afraid. Removing datadir=/usr/local/mysql/data did not work. And prior to using phpMyAdmin, I was able to login via Terminal with this in place.
Try removing my.cnf. It isn't required and seems to be giving you problems.
Also, the mysql socket value is what comes with new Macs with Snow Leopard.
MySQL doesn't come on any new Mac except with Snow Leopard Server. I think we've had this conversation before and came to the conclusion that you don't have the server version, just a jacked up client.
I am noticing that the Terminal error message I get is saying:
/usr/local/mysql/bin/mysql: unknown variable . . .
whereas the data directory path is /usr/local/mysql/data
There is no data directory in /usr/local/mysql/bin/mysql
The program that is reporting the error is is /usr/local/mysql/bin/mysql.
My MySQL installation does not have a my.cnf file. It does have a number of example cnf files that I could use if I wanted to jack up my installation. None of them have a "datadir" value in them. If you don't want to get rid of my.cnf altogether, the just get rid of all of the datadir values inside it.

MySQL data into XML for DW CS3

Hi.
I have been developing mainly with the MySQL/ php frameworks,
but am keen to integrate MySQL data via SPRY. if I understand
correctly, data can only be in XML format to be available for the
SPRY features.
So my question is, how can/ what is the best practise for
creating XML data from a MySQL database, one that does not have to
be exported/processed by a user everytime data changes in the db.
Would InteraKt's XML import/export accomplish this or is
there any facilities from within DWCS3?
Many Thanks,
M Turner

In the Spry XML Data Set dialog box, click the Browse button
to navigate
to the page that generates the XML on the fly. By default,
the Select
XML Source dialog box displays only XML files. Click the
Files of type
drop-down menu to select All files (*.*). You can then select
a PHP,
ASP, or ColdFusion file.
As long as you have a testing server running locally, DW CS3
will
generate the XML schema correctly when you click Get schema
in the Spry
XML Data Set dialog box.

Could not resolve this reference. Could not locate the assembly "MySql.Data, Version=6.8.3.0

I am getting the subject error message when I try to compile, using VS, a VB Forms app which I had been developing on a desktop machine but which I am now developing on a laptop. I am using exactly the same VS files as they are in Dropbox. (And
incidentally I no longer have access to the desktop machine.)
The subject error message points to: Imports MySql.Data.MySqlClient
I have been down this path before and can usually, eventually, resolve it by installing something and then creating a reference to the right dll. For me that's an iterative process as it's not always obvious, to me, what I need to install and which
file needs to be referenced.
But the only help I am seeking from this groups is: What makes VS think that it needs "Version=6.8.3.0"? I am pretty certain that I never told it that it needed that version. And how can I change its mind so that it will compile
using a different version?
I keep telling it to use
... but it doesn't like it and I don't know if the problem is that it's the wrong version or if the problem is that it doesn't contain the right stuff.
Thanks for whatever guidance anyone can offer.
Thanks, Bob

The version shown here does not say that this is the version that is required, it indicates the version of the assembly that was referenced.
What will determine the version that is required, or if a specific version is required, will be the properties that you set on the reference, which can be viewed by clicking on the reference in Visual Studio and setting "Specific Version" to true
or false, the software in question and if the signatures match up to what you are binding to.
Now, for your specific issue, I tend to add a NuGet reference for SQLite and it makes updating versions, and maintaining specific version requirements, much nicer than using a globally installed version of the SQLite libraries.
It would be greatly appreciated if you would mark any helpful entries as helpful and if the entry answers your question, please mark it with the Answer link.
Thank you very much TSoftware. Especially for telling me about "Specific Version" - I changed that to false and they the app compiled. Thanks very much. Bob

MySQL data files: where do they live

I am building an online system using mySQL. I have two (I hope) simple questions.
1. Where do the data files live eg. What do I have to backup to be sure my data is safe?
2. I built the system on a Mac OS 10.3 machine (not 10.3 server). How do I transfer the mySQL database structures to the (now included) version of mySQL running in Mac OS 10.4 server?
Any advice will be much appreciated.

On OS X Server, the standard location for the MySQL data files is: /var/mysql. Any databases you create will wind up in there. If you install a fresh copy of MySQL onto OS X from a MySQL package, they go into /usr/local/mysql/data.
You have a couple of options for the transfer. 1) Using MySQL, use mysqldump to create SQL files of your database tables, both structure and data. 2) Using something like phpMyAdmin, you can export the tables into a structure that can then be imported on your 10.4 server. 3) Copy the relevant database directories from your /var/mysql directory on OS X 10.3 into the /var/mysql directory on your 10.4 Server. Either stop MySQL on 10.3 first or lock the tables before you do a copy. Then, after plopping them into the 10.4 directory, restart MySQL on 10.4 and you should be good to go.
If you are interested in knowing how to use the tools like mysqldump or how to import from a text file, MySQL's site has a section of documentation on these: mysqldump / mysqlimport

Also when I tried to update my MYSQL connector / J driver to version 5.1.5 from 5.0.5 (NB 5.5.1) and 5.0.7 (NB 6.1), I could not get it work (looooong time to search some JDBC classes and with no response in the end) on both of my Netbean 5.5.1(on PC) and Netbean 6.1(on laptop) IDEs.
Could anybody look into this issue.
Many thanks

Using MySQL data source in OWB

Hi All,
I need to use a MySQL data source in OWB. Could you please tell me the steps needed to define and configure the MySQL module in OWB?
Thanks and Regards,
Amit

Directly in the source component, or in the expressions property of the data flow?
If the latter, what happens when you preview your expression?

PHP MySQL data display problem

I am having trouble getting data to display on my web page.In Dreamweaver CS3, I created a new page.
Selected PHP as the type.
Saved it.
Connected a database and created a recordset (all using Dreamweavers menus. I did not write any code).
NOTE: The database is on a remote server.
The TEST button displayed the records from the recordset with no problem.
On the new page, I then typed some text.
Then dragged some fields from the Bindings tab to the page.
I saved it and then went to preview it in my browser.
The page comes up completely blank. Not even the text shows.
I then saved the page as an HTML page.
When I preview this in my browser, the text shows, but the fields and data do not.
I then tried creating a dynamic table (again, using the Dreamweaver menus.).
A similar thing happens, ie. If I save it as an HTML, the text shows and the column labels and border shows, but no data.
Nothing shows if I save it as a PHP file.
I can view the data online using files created by PHPMagic, so I know the data is there and retrievable.
It is just in pages created in Dreamweaver that don’t work.
What am I doing wrong?

My web server supports PHP. I can disply PHP pages created by other software packages, just not the Dreamweaver ones.

Subject: PHP MySQL data display problem
To view php pages - or pages with PHP code in them - in a browser, the page must be served up by a Web server that supports PHP. You can set up a testing server on your local machine for this purpose. Look for WAMP (Windows), MAMP (Mac), or XXAMP for some easily installed packages.

MySQL date fomat with PHP

I have a problem with format date stored in mySql db ( in the
fied named 'dt_news') as dd-mm-yyyy.
Now when I view my php page where I show all the records, I
have the following type yyyy/mm/dd.
Please help me to modify the attached code an have that
result.

Add to your code
<?php
function mysql2date($date){
$temp = explode("-",$date);
$newdate = $temp[2] . "/" . $temp[1] . "/" . $temp[0];
return $newdate;
Then instead of:
<?php echo $row_View_News['dt_news']; ?>
Use:
<?php echo mysql2date($row_View_News['dt_news']); ?>
This will change the mysql date format from YYYY-MM-DD to
DD/MM/YYYY

Plotting graph in LabVIEW from MySQL data table

Is there any possibility to plot the data from MySQL data table in LabVIEW graph/chart??
can somebody help me??
thanks...

I am new with LabVIEW and I am also with the same problem.
No problems to write data into MySQL, but when trying to read data neither "fetch element data" or "get properties" answer !
It is not possible to get a simple recordcount using the "get properties". The same script give the right answers with MS Access, only changing the DB reference from "connection string" to a "UDL". Does somebody can post an example retriving data (that runs ok even with a WHERE clause in the recordset) using MySQL ?
The connection string I am using is:
Driver={MySQL ODBC 5.1 Driver};Server=127.0.0.1;Database=DBname;User=root;Password=xxx;Option=785;

MySQL - Another 'Can't connect through mysql.sock' question...

Hey, folks.
So I'm trying to install MySQL to run with PHP on my PowerBook G4 (running 10.4.7, non-server edition) to use it to test out a shopping cart program for a website I'm building.
I had it working as of Monday, when I installed it, got all the permissions set, built the necessary tables, and changed the root password (and logged in just to make sure it worked before retiring for the night)...but today I realized that I had somehow installed the wrong version of MySQL (I connected to it earlier today and discovered it was 4.026 - and I needed to be running MySQL 4.1.20, in order to be running the same version as my webhost).
So I decided to upgrade. I downloaded and installed the 4.1.20 file, followed the directions about creating the system tables, changed permissions via sudo chown -R mysql:mysql data...and now, when I go to change the root user password (just to make sure it's still the same as it was), I get the following error:
error: 'Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)'
Check that mysqld is running and that the socket: '/tmp/mysql.sock' exists!
This error also occurs when I try to simply startup MySQL. I also now find I can't connect via MySQL Admin, either - it gives me the same error. Pinging the host works, however.
Sooo...anyone have any ideas? I've read up on the forums re: Apple changing the socket to /var/mysql/mysql.sock as of 10.4.4, but it seems that would have affected me earlier this week when I was running the previous version of MySQL, too (I certainly haven't upgraded the OS since then).
Regardless, I can't connect through MySQL Admin using the /var/mysql/mysql.sock socket, anyway...nor the standard /tmp/mysql.sock.
Any thoughts on what might be causing this? I should confess, I'm well-versed in DOS (ugh), but UNIX is not really my strong suit, so I'm still figuring out how to get around in the Terminal...
Thanks so much for any input you can give me!
(Oh, one more thing, since it'll probably come up - I'm not currently connecting via PHP, but I will be eventually. Right now, I just want to be able to change my root password, and login from the Terminal)!
Thanks again!\
PowerBook G4 1GHz 15 Mac OS X (10.4.7)

Alright, folks.
Somehow my computer has fixed itself. After wiping the mysql directories entirely, then reinstalling, I was still getting the same error.
After going back to the original "MySQL-On-Mac" site at Marc Liyanage's entropy.ch site & following some of the instructions there, somehow my problem seems to have fixed itself.
I wish I could tell you what the solution was (to benefit anyone else having this problem), but since I was simply following the unix commands listed there (without much explanation, at times, as to what they were doing), I just know that somehow it worked.
(But if I had to make a guess, I think it had to do with starting the server via sudo ./bin/mysqld_safe &)...

MySQL Data Server Wont's start

I had all my local setup running and my databases backups and local connections working fine, since i did the last security update my MySQL server wont Start and so all my Localhost or 127.0.0.1. host, on my sites and CocoaMySql, "Reason: internal Error". when starting it from my System preferences.
Any recomendations?
thanks indeed!
