Perfect, that'll work.

> I am encountering an error trying to update a BOOLEAN type through an
> updatable ResultSet.  My table looks like this:
> CREATE TABLE file_store (
>   path VARCHAR(255) NOT NULL,
>   network VARCHAR(32) NOT NULL,
>   file_blob BLOB,
>   file_md5 VARCHAR(32),
>   is_directory BOOLEAN NOT NULL DEFAULT false,
>   PRIMARY KEY (path, network)
> );
> My SQL looks like this:
> SELECT path, network, is_directory FROM file_store
> WHERE path=? AND network=? AND is_directory=true FOR UPDATE OF path, network, is_directory
> My Java code looks like this:
> ...
> resultSet.moveToInsertRow();
> resultSet.updateString("path", dirPath);
> resultSet.updateString("network", network);
> resultSet.updateBoolean("is_directory", true);
> resultSet.insertRow();
> An exception is thrown in the call to updateBoolean() as follows:
> java.sql.SQLException: An attempt was made to put a data value of type 'byte' into a
data value of type 'BOOLEAN'.
> It's a shame, I was looking forward to using the new BOOLEAN type before I roll out the
next version of our software.  For now I will fallback to SMALLINT.  Does/will ALTER TABLE
support a change from SMALLINT to BOOLEAN?
