Hi All

I am creating a java program for college, it will help kids with words and shape maybe more if I can figure out the database as this is my first time doing an application that involves a database.

What will happen:
A new user will create a profile and exiting user will login, when launch game a geme_session will be created to, record the date and the user, the user will select a category (word / shape) and begin to answer the questions, when the user has finished all the 5 to 10 question the play session will record the score, user, category and the game_session. if the user decide to select another category a new play session will begin and again when ended will record and so on.

Need Help with:
need help with getting the database right, I have done a EER Diagram in workbench and was hoping some expert will guide me right.

As I said before I am new to this so go easy on me.

Some links to good tutorials, example schemas would be great.

Watch Monuments Men/The Lego Movie HD

The Monuments Men, co-written and directed by George Clooney, sees a bandage of ageing art experts adventure to the foreground curve of Apple War II to balance important works of art baseborn by the Nazis. It's a alluring true-life adventure that has suspense, hidden treasure, and the ultimate villain - Hitler. Still the blur requires fretfulness of animate to get through.Clooney himself plays Harvard art conservationist Frank Stokes, who handpicks his aggregation and again leads them to Germany to acquisition such priceless artefacts as the Ghent Altarpiece and the Bruges Madonna by Michelangelo. This Dirty Dozen-type aggregation of academics and professionals comprises such agitating actors as Matt Damon, Bill Murray, John Goodman, Jean Dujardin, Bob Balaban and Hugh Boneville, while Cate Blanchett stars as a French babysitter who is aboriginal apprehensive of the mission, again accessible in tracking down the pilfered works.

Despite accomplished performances from the cast, and any amount of agreeable banana scenes, the blur doesn't absolutely plan because it can't assume to get a fix on the accent it wants to take, seesawing inconsistently amid airy and somber. There are moments of ablaze amusement (mostly in the exchanges amid Murray and Balaban), and some agitating $.25 as the men accident their lives to save admired pieces of art. What's defective throughout the account is a faculty of urgency, even if lives are in approaching danger. A arena in which Damon accidently accomplish on an atomic abundance is never tense, instead schmaltzy. Things do aces up in the endure twenty minutes, with our heroes dispatch to locate and accomplishment above artworks afore the Germans can abort them or the Russians can get their easily on them. But it's too little too backward by then.It's axiomatic from the again speeches Clooney makes about the amount of art and ability that he charcoal committed to administering accepted films that still administer to say something important about the world. But while The Monuments Men has a blue-blooded bulletin at its heart, it's just not actual acceptable as a whole. I'm traveling with two out of five. A crushing disappointment.

Question about: Orphaned document changes detected (3 replies)

Good day, i'm having a small problem with this:
I'm using the workbench 5.2.47 CE (i don't like the new version so i prefer this, thank you) under windows 7 sp1 x64.

I was happily introducing data in my DB, when my pc froze before i could click on "Apply" to save the data, so i had to hard-reboot; Now i have the following message on the bottom of the main window:

"Orphaned document changes detected
Unsaved changes of an SQL Editor workspace found.
To restore them, open the corresponding SQL connection and save the SQL data..."

All right! I click on "Open connection to start querying" Option at the left (has a small gold/yellow lightning)... All my previous data are there except for the ones i want to recover, those which i was unable to save when the pc clogged.

My question is: Am i doing something wrong? Where and how i have to "open the corresponding SQL connection" to recover my data?

Replication update problem (no replies)

Hi all, I have a problem when using MySql workbench to update a replication.

I updated the master's schema (alert, create table actions) using workbench's "Synchronize Model", but the slave's didn't receive any change and got no error when I execute 'show slave status'.

However, everything works well when I executed the SQL statement through the command line.

It's that MySql workbench's synchronize statement will not write to binlog?

Please forgive my poor English...

Sorry for the ultimate "workbench newbie" question but how do I start to access the SQL Editor right after I have created a brand new table? I have clicked on the "Apply" button right after setting up all of my columns and specifying the data types but it doesn't readily go into the SQL Editor.

I have been trying to get mysql workbench to connect to my BSD mysql server from a windows machine. I can successfully do this from my laptop running windows 7. I have the users made 'netuser'@'localhost', and the user 'netuser'@'%' with privileges on *.* All the settings from the laptop are set the same in the desktop but it will not let me in. I know that mysql is running because I can connect via ssh without issues. Does anyone have any ideas?

Workbench traffic rate measurement (no replies)

Hello,

How is the Traffic rate measured on mysql workbench?
Is it a reflection of all network IO on the server machine?
Or it is isolated to all network IO specifically related to mysqld?

How is this measured/implemented on a linux box?

The reason I'm asking is that when I measure the active IO on the machine with linux admin tools and wireshark, I get comparable figures that match up.

however when I'm running the workbench, (from a remote machine), workbench reports traffic at approximately 60% more.

Also I'm assuming that the units that workbench reports in is in face MegaBytes per sec - is this correct?

Thank you.


btw, workbench is running on linux
version is :
MySQL Workbench CE 5.2.47 10398

EER Diagram - Tables stuck (4 replies)

Hi everyone!

I use this Workbench: 6.08.11354 build 833 Community Edition.

I made an EER Diagram with the Model Tool and somehow (after it worked fine at first), all my Tables are now stuck at the top of the window.
It is still possible to alter the property "Top" manually, but i cant drag & drop the tables below x=0. (dragging from left to right works, though)

I searched quite a bit to find an option that i unintentionally turned on(off?) but couldn't find any so far.

Please help :-)

Greetings

I have just installed mysql community server and workbench. I am following the tutorial "6.1 Administering a MySQL Server", but when I get to step "7. On Microsoft Windows, select the appropriate MySQL service for the MySQL connection." there is no service in the list.

I have the "Path to Configuration File:" set to "C:\ProgramData\MySQL\MySQL Server 5.6\my.ini" per the tutorial, and have verified that the file is at this location. But it keeps coming back with "No MySQL service found."

Any help would be appreciated.

Running WB 5.x plugin in WB 6 fails (no replies)

Hello,

I've been away from my plugin I developed until 1-2 years ago. Some things have changed in WB 6 now (using 6.0.9).

I still have the plugin jpa_export_plugin_grt.py in my user's modules directory and it's still in the list in the UI under Tools -> Catalog -> Export JPA Annotated Classes...

However, when executing the script a dialog pops up saying:

Error during "Export JPA Annotated Classes..."

mforms: attempt to add a subview already contained somewhere

I see this is some kind of check from the mforms lib when a subview already has a parent, but since the code worked on previous WB versions (namely 5.1 and 5.2) I have to find out what it is.

How do I debug this?

I can't seem to achieve anything useful from the scripting shell >>> prompt.

Using

execfile('C:\\Users\\MYSELF\\AppData\\Roaming\\MySQL\\Workbench\\modules\\jpa_export_plugin_grt.py')

just does absolutely nothing.

I also removed the code that actually shows up the options UI, but this doesn't seem to have any effect?

What's wrong? It seems like the code gets/got cached somewhere.

Maintaining connectivity with SSH (2 replies)

Hi.
I use MySQL Workbench 6.09 on a Mac to connect to a remote db via SSH tunneling from home.
A few months ago, I switched to Comcast-Xfinity for my ISP. Since then I noticed all my SSH connections would die. i googled around and found that i can avoid the issue by adding
Host *
TCPKeepAlive yes
to
~/.ssh/config

this fixed all my SSH terminal connections - they would pretty much stay up.

However, my db connections via SSH tunneling in MySQLWorkbench will still die after a very short idle period.

Is there a way to avoid this? It has been such an annoyance, i've started using Sequel Pro instead, which doesn't have this issue. However, I would like to go back to MySQL Workbench if there was a a way to resolve my problem.

any suggestions would be much appreciated!
Thanks
Ed
