SetNull()

Bool_t TODBCStatement::SetNull ( Int_t  npar )

finalvirtual

Set NULL as parameter value If NULL should be set for statement parameter during first iteration, one should call before proper Set... method to identify type of argument for the future.

For instance, if one suppose to have double as type of parameter, code should look like: stmt->SetDouble(2, 0.); stmt->SetNull(2);
