SQL: JDBC meta-data is always using an empty string for column label

[astefan]

The spec defines the column label as

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.

But in our case, it's always returning an empty string.
