[jira] Created: (DDLUTILS-54) Column comparison does not check on native types

Column comparison does not check on native types
------------------------------------------------

         Key: DDLUTILS-54
         URL: http://issues.apache.org/jira/browse/DDLUTILS-54
     Project: DdlUtils
        Type: Bug
    Reporter: Konstantinos Stathatos
 Assigned to: Thomas Dudziak 
    Priority: Minor
 Attachments: zementis_tests.ant

The attached Ant script  creates a table (in Derby) and then tries to alter it, using the same database description. I would expect the DdlUtils would not try to modify anything as the database has not changed.

However, the database defines a BOOLEAN column and a FLOAT column which in a Derby are mapped to a SMALLINT column and a DOUBLE column. With such a mapping, next time the columns are compared DdlUtils finds them different since the type codes are different. As a result, it tries to modify the columns even though the modification is not necessary.

Generally, such modification is really harmless. However,  under my particular use case, occasionally a DBA would have to get involved and manually update the database if modifications are needed (i.e. if a non-empty alter sql is generated).  This means that taking the extra step to check based on the native types if the modifications are material or not would be important.

[jira] Resolved: (DDLUTILS-54) Column comparison does not check on native types

Posted by "Thomas Dudziak (JIRA)" <ji...@apache.org>.
     [ http://issues.apache.org/jira/browse/DDLUTILS-54?page=all ]

Thomas Dudziak resolved DDLUTILS-54.
------------------------------------

    Resolution: Fixed

I've added a unit test for this (testIssue54 in org.apache.ddlutils.io.TestAlteration) and apparently this is already fixed.

Konstantinos Stathatos updated DDLUTILS-54:
-------------------------------------------

    Attachment: svndiff

The svndiff file contains the code changes in SQLBuilder that I think address the issue. It also includes a small change in CloudscapePlatform.java that adds what it seems to be a missing type mapping.
