jchd Posted February 23, 2016 Share Posted February 23, 2016 The name of the column you want is undefined since there is no column alias to "COUNT (id_address)", so when you ask the value of the field id_address the ODBC driver doesn't know what you want. You can do either give the column an alias name using the optional AS clause: _Connetti_DB_Mysql() ; apro db $rsCustomers_MY = $objConnMY.Execute("SELECT COUNT(*) as cnt FROM ps_address") ; trovo il totale in ps address With $rsCustomers_MY While Not .EOF ConsoleWrite(.Fields("cnt").Value & @LF) ;$ps_Country_code_array[$b] = (.Fields("cnt").Value) $b += 1 .MoveNext WEnd .Close EndWith _Close_DB_MYSQL() ; chiudo db or address the field by index: _Connetti_DB_Mysql() ; apro db $rsCustomers_MY = $objConnMY.Execute("SELECT COUNT(*) FROM ps_address") ; trovo il totale in ps address With $rsCustomers_MY While Not .EOF ConsoleWrite(.Fields(1).Value & @LF) ;$ps_Country_code_array[$b] = (.Fields(1).Value) $b += 1 .MoveNext WEnd .Close EndWith _Close_DB_MYSQL() ; chiudo db BTW are you sure you want to close the connection right after obtaining the total number of rows?

faustf Posted February 23, 2016 Author Share Posted February 23, 2016 yes i think is much better if after select or work , with db you close it , or not?? Link to comment Share on other sites More sharing options...
jchd Posted February 23, 2016 Share Posted February 23, 2016 In the general use case, you init the engine, open one or more connection(s), perform the work and only close the connection(s) just before terminating. Needlessly opening a new connection or reopening a connection previously closed is a waste of cycles, since the engine needs to re-parse the whole database schema everytime. It doesn't show much with DBs which contain just a couple tables and little around (few triggers, etc.) but it's very noticeable with DBs having hundreds or thousands of tables and a very complex schema.
