Subject [jira] Commented: (DBUTILS-24) [dbutils] Modify BasicRowProcessor to use the column label
Date Wed, 07 Oct 2009 09:37:31 GMT

    [ https://issues.apache.org/jira/browse/DBUTILS-24?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12762964#action_12762964

Dmitry Mamonov commented on DBUTILS-24:
---------------------------------------

I'm using mysql-connector-java-5.1.7-bin.jar driver. Here is my problem:
SELECT parent.name as parentName, child.name as childName
FROM peoples parent
LEFT JOIN peoples child on child.parentId = parent.id
WHERE ....;

This way getColumnName() method returns "name" for 1st column, and (sic!) name for 2nd column,
so I cant reach values from first colum at all using  MapListHandler for example.

I'm fixing it manually changing getColumnName() to getColumnLabel() in BasicRowProcessor class,

but it looks not so cute.

> BasicRowProcessor.mapColumnsToProperties currently uses 'getColumnName' to 
> determine what property to set on the bean. It would be more flexible if it 
> used 'getColumnLabel'. This would allow the developer to specify the property 
> name as an alias to a column in the sql query.
> For example 'select last_name lastname, first_name firstname from employee'. 
> Note that 'getColumnLabel' will defaults to the column name if no alias is 
> specified in the query.
