Julien Aymé commented on DBUTILS-57:
------------------------------------
>From the javadoc description of the getColumnLabel method (see
>http://java.sun.com/javase/6/docs/api/java/sql/ResultSetMetaData.html#getColumnLabel%28int%29
> )
"Gets the designated column's suggested title for use in printouts and
displays. The suggested title is usually specified by the SQL AS clause. If a
SQL AS is not specified, the value returned from getColumnLabel will be the
same as the value returned by the getColumnName method."

> Key: DBUTILS-57
> URL: https://issues.apache.org/jira/browse/DBUTILS-57
> Project: Commons DbUtils
> Issue Type: Bug
> Environment: hsqldb-1.9.0-rc4 memory mode
> DBUtils 1.2
> Reporter: Wynand
>
> Using a query with an alias, hsqldb engine doesn't populate the column name
> metadata only the column label metadata.
> In such a case the column isn't mapped.
> To resolve this, the column label should be used in case the column name is
> not available.
> Here is a snippet from
> org.apache.commons.dbutils.BeanProcessor.mapColumnsToProperties line 393 :
> ...
> for (int col = 1; col <= cols; col++) {
> String columnName = rsmd.getColumnName(col);
> // columnName is empty, revert to column label
> if (columnName.length() == 0) {
> columnName = rsmd.getColumnLabel(col);
> }
> ...
