[Monetdb-developers] specifying NULL when using ODBC param_query

Hello Everyone, Is there any way to specify a null value when using ODBC param_query, in case of SQL_Query we do not really end up facing this problem as we build our own query string and then execute sql_query, sql_query is potentially unsafe of sql injection attacks, and thus using param_query makes alot of sense, but param query makes it hard to specify the data type nuetral NULL value, if we try specifying blank values like 0 in case of number and "" in case of string, these blank values will end up taking space in the database and thus would be expensive in terms of memory consumption, a database specific NULL value would leave the field null with no memory consumption. Thank you everyone in advance. kss ram
