[ http://issues.apache.org/jira/browse/DDLUTILS-86?page=all ]
Thomas Dudziak updated DDLUTILS-86:
-----------------------------------
Fix Version: 1.1
> New attribute of Column. Native type is a value of TYPE_NAME in the result
> set of DataBaseMetadata.getColumns(...).
> -------------------------------------------------------------------------------------------------------------------

> Key: DDLUTILS-86
> URL: http://issues.apache.org/jira/browse/DDLUTILS-86
> Project: DdlUtils
> Type: New Feature
> Components: Core
> Reporter: Yauheni Prykhodzka
> Assignee: Thomas Dudziak
> Priority: Minor
> Fix For: 1.1

> It was been discussing with Thomas Dudziak. We try to use DdlUtils to compare
> two and more databases. In some cases we need the functionality of JDBC call
> DataBaseMetadata.getColumns(...). This call returns among other things the
> native type of the column as well. Sometimes it's different than hard coded
> predefined types for a platform. This difference is very important if you
> compare two databases. Here is the begin of my email to Thomas about that
> problem:
> > i'm developing now a small tool that should compare
> > databases (of the same type). I need to get native
> > types possibly without any modifications. For example
> > the base implementation of DdlUtils returns SMALLINT
> > instead of TYNIINT for MySql. Probably i can get
> > SMALLINT both for TYNIINT and for some other native
> > type if i'll use the current implementation of
> > DdlUtils. So the result of the compare can be wrong in
> > this case!
> Here also changes of classes Column and JdbcModelReader.
