First of all I recommend swicthing to MySQL Administrator, the MyCC is deprecated and will have no future updates.

Do you want a foreign key relationship, or do you just want to join the tables in a query? Can you give more details?

http://dev.mysql.com/downloads/administrator/1.0.html

 

by: mte01Posted on 2004-12-03 at 07:30:32ID: 12736836

I want to create a foreign key relationship between 2 tables.......(as in an ER diagram in MS Access)

 

by: mte01Posted on 2004-12-03 at 07:31:13ID: 12736844

& specify plz right now regarding MySQL CC

by: mte01Posted on 2004-12-03 at 07:40:56ID: 12736921

I need to do it using a GUI interface like the ER diagram in MS Access in which you link tables directly...isn't that possible??

by: SqueebeePosted on 2004-12-03 at 07:51:06ID: 12737033

I believe this tool lets you do that:

by: mte01Posted on 2004-12-03 at 08:54:45ID: 12737777

Ok...it worked.....but I could not find the tables that I had already done using MySQL CC

 

by: mte01Posted on 2004-12-03 at 09:17:26ID: 12738033

and I could not import an SQL script........

 

by: SqueebeePosted on 2004-12-03 at 09:34:48ID: 12738223

Use the mysql query browser for SQL scripts.  http://dev.mysql.com/downloads/query-browser/1.1.html
Hit control-O to open a SQL script and click the execute button to run it.

Odd about not seeing the tables. Were they temporary tables? Were they designed but not actually created?

 

by: mte01Posted on 2004-12-03 at 09:54:25ID: 12738454

No....No..they were created......

 

by: mte01Posted on 2004-12-03 at 09:55:24ID: 12738465

By the way, what's the latest version of the MySQL server to download right now??

 

by: SqueebeePosted on 2004-12-03 at 09:59:57ID: 12738514

4.1.7 is the latest stable, 5.0.2 is the latest alpha?

 

by: mte01Posted on 2004-12-03 at 10:13:43ID: 12738631

Let's say I'm staying on my version, and right now I am using SQLYogo which is the best uptill now, but I can't change a table's format to InnoDB (inorder to manage relationships)....it seems that there's a problem with this type on the server.....any help??

 

by: mte01Posted on 2004-12-04 at 16:06:33ID: 12746090

I successfully installed MySQL Server 4.1.7, but the problem remains with the DB4 Designer that Squeebee offered to downlooad, it seems that it cannot read any DBs that have been created earlier on MySQL server....(it seems to be very poor in general)...any help??

 

by: ZontarPosted on 2004-12-04 at 21:18:50ID: 12746808

Your best solution is to free yourself from the "need" for GUI tools by learning how to do this on the command line, which will always work on all MySQL installations.

NOTE: This is purely my own opinion, and may not reflect the position of MySQL AB or anyone else.

 

by: mte01Posted on 2004-12-04 at 22:14:07ID: 12746983

I know how to do it from the command line :).....the point is I want to "printscreen" a relationship diagram between the tables in my DB, so I can add it in my report, so the reader can understand the relationships in my DB directly.

 

by: ZontarPosted on 2004-12-05 at 00:02:23ID: 12747171

I use Visio or Access for that.

 

by: mte01Posted on 2004-12-05 at 00:06:36ID: 12747177

So you need to import your MySQL DB to Access or Visio inorder to manipulate your tables.....how is this possible??

 

by: ZontarPosted on 2004-12-05 at 00:24:37ID: 12747202

Install MyODBC (or Connector/ODBC as it's known now), then use WIndows ODBC to set up the MySQL DB you want to import as a datasource: http://dev.mysql.com/downloads/connector/odbc/3.51.html

The only hard part was that I could never get the FK relationships to import correctly, but those are easy enough to add by hand once the tables are imported.

I've also used Dia ( http://www.gnome.org/projects/dia/  ), although it wasn't quite there yet. But that was a couple of releases ago.

 

by: mte01Posted on 2004-12-05 at 00:28:54ID: 12747210

Great...Great...I'll be trying it & informing you of the results.....

 

by: psadacPosted on 2004-12-06 at 07:42:25ID: 12754934

from memory, i think there is a functionnality in dbdesigner, called 'reverse engeneering' that will import your existing tables in dbdesigner.

you have also phpmyadmin which provide a similar functionality, but it is not installed by default. it can generate a pdf schema of your database.

 

by: mte01Posted on 2004-12-06 at 11:26:09ID: 12757269

I'll be looking into your comment & I'll be informing you of the result....

 

by: mte01Posted on 2004-12-07 at 21:28:46ID: 12770792

All the options (reverse engineering & other similar options) are leading to the DB, but they are not showing any previously made tables, I think making an ODBC souce for a mySQL DB is the best solution.
