----------------------------------------

Looks good to me in general (though I'm not familiar with ODBC).

> Currently, if user wants for example to insert 20k records they need to call {{SQLExecute}}
for the 20k times. More than that, internally, we transmit and execute the same SQL query
20k times. This is a huge overhead. We should only transfer sql query once, transfer all the
parameters in a batch and then execute it once using some fast, possibly internal API.
