Hi, I'm new with MonetDB. I'm trying to use it but it seems that not store tuples that I insert. I'm using MonetDB5 and jdbc driver to connect to it. I'm using PreparedStatement to insert data in the demo database and table mytable whit connection with autoCommit true. It seems all ok while I'm inserting tuples but, when I try to select count(*) from mytable, from the client I see : % sys. # table_name % count_ # name % int # type % 1 # length [ 0 ] Which is the problem? Can anyone help me? tnx Raffaele
