Reads a batch of rows.
rows_view read_some_rows( execution_state& st, error_code& err, diagnostics& diag);
The number of rows that will be read is unspecified. If the operation
represented by st has
still rows to read, at least one will be read. If there are no more rows,
or st.should_read_rows()
== false,
returns an empty rows_view.
The number of rows that will be read depends on the connection's buffer size. The bigger the buffer, the greater the batch size (up to a maximum). You can set the initial buffer size in the constructor. The buffer may be grown bigger by other read operations, if required.
The returned view points into memory owned by *this. It will be valid until *this
performs the next network operation or is destroyed.
