Currently, when forward engineering a data model to MySQL, the tables default to the default engine.

Would be preferable if the Architect would allow the user to select the database engine to be used for the table.

I am able to generate and run ddls from a schema imported from a Postgres implementation. However, when I try to populate the data at the db level (ie. all tables), I get the following error:

Some further troubleshooting:

When I create a table from scratch in the playpen, I am able to generate the DDL for MySQL. When I try to bring a single table from Postgres and engineer it into MySQL, I get the error.

I open a connection to a Postgres database and bring the contents into the playpen. I then try to forward engineer the model to a MySQL Database (connectivity confirmed) and I receive the error message detailed below. I even tried, with the same results, to forward engineer a single table (no relationships).

The same error occurs irrespective of the names of the source and target databases. If the function is designed for a single table copy, I suggest simply disabling the selection of a database.

Create a simple table in MySQL. Populate the table with a few values (I created a single column).
Use Architect to forward engineer the table to Postgres. This works successfully.

Use the 'Copy Table Data' to copy the contents from MySQL to Postgres. You get the following error:

Operating System:
Mac OS X 10.5.7 (i386)

Runtime Environment:

Memory:

To replicate:

Select 'Forward Engineer SQL Script'
Select a Target Database
Click on Properties
Click on 'OK' in Properties Window
You get 'A connection with the name <Database Connection> already exists'

What I think should happen is the Properties Window is closed and control is returned to the 'Forward Engineer SQL Script' window.

It would be great if the user guide referred to the Architect version number it relates to on the cover sheet. I found myself working with an outdated copy of the guide!

To reproduce:

Mac 10.5.7
MySQL 5.1.35

Create a connection to a local installation of MySQL. The playpen can be populated with metadata from the instance. Attempt to remove the connection via right clicking on the connection and selecting 'Remove Connection'. Receive the following error:

Hi,

Is there an easy way for the community to create new transformation functions and to share them? Ideally, one would be able to go to a community area, review the available functions, and import them into the DQ Guru as needed.

Thanks

Hi,

I've been playing with DQ Guru. As a non-technical individual, it would be nice to be able to create 'super transformations' that are made up of the base transformations already contained within DQ Guru. I would then be able to reuse some of the more complex cleansing processes that I've developed.

Thanks,

Postgres 8.3.7

MySQL is running on MAC OS X

To reproduce:

DQ Guru release 0.9.5-20090423135916

Going against a MySQL database (R5.1 - movies), Follow the steps listed for creating a De-duping project in the DQGuru user manual. When you get to the run match engine step, the following error occurs:

ca.sqlpower.matchmaker.SourceTableException: PreCondition failed: Source table structure has changed!

The tables were created just before running the process. I'm pretty sure there's not any 'legacy' items that could be impacting this - in any case, an abort like this should not occur.
