The MySQL provider does not seem to allow the setting or getting of binary data, though it works for the PostgreSQL and SQLite backends. This seems to be the problem code in gda-mysql-provider.c:


static GdaDataHandler *
gda_mysql_provider_get_data_handler (GdaServerProvider  *provider,
				     GdaConnection      *cnc,
				     GType               type,
				     const gchar        *dbms_type)
{
	...

	else if ((type == GDA_TYPE_BINARY) ||
		 (type == GDA_TYPE_BLOB)) {
		TO_IMPLEMENT; /* define data handlers for these types */
		dh = NULL;
	}
