Query:
select count from table_a;

Retrieve results using:
int count = resultSet.getInt(1);

Problem:
Driver needs to translate index to a column name. In MySQLResultSetMetaData.getColumnName(index), the method getColumnInformation(column).getOriginalName() returns "". If I changed the code to this workaround:

public String getColumnName(final int column) throws SQLException {
String results = getColumnInformation(column).getOriginalName();
if (results == null || "".equals(results))

{ results = getColumnInformation(column).getName(); }

return results;
}

then it works. This is because getColumnInformation(column).getName() returns "count" which is what is needed in ColumnNameMap.getIndex(name).

I don't know the code deep enough to tell if the workaround above is the best way to address the issue, please advise.
