Thats not logical.
http://doc.trolltech.com/4.7/qsqltablemodel.html#rowCountdoesn't
mention what is exactly rowCount, and one should expect the number
of rows based on the name...

fetchMore will then fetch all rows. I don't want that, just would like to
know the number of rows, or just load the last record.

 you execute 300 transactions. If you use db.transaction()
