odbc

问题 I am using ODBC to link some tables to a MySQL database hosted remotely. It's not a very good host, so it fails quite often. When this happens, it will hang Access (version 2003) for about 20 minutes, and then finally come up with an error (3146), saying that the connection unexpectedly closed. The only way I can get out of it is by End Tasking access. This can be frustrating, especially if I just wrote some code that wasn't saved yet. Is there a way to cancel the odbc operation, perhaps by

问题 I have some problem with connection to my Vertica. I use PHP and PDO ODBC driver (thrue unixODBC). When I connect to Vertica via isql and select records from table all data are fine encoded - fields with UTF-8 (non ASCII symbols, for example cyrillic) correctly prints. If connect from web with PHP script and execute same query that fields has some unicode characters like this \u001A\u001A\u001A\u001A Each \u001A represent a one non ASCII symbol and can't be printed. I found that this problem

问题 I've seem to have a memory leak. I found a post on stackoverflow recommending 'using' method but this doesn't seem to fix the issue. I am using Red Gate memory profiler which shows an increase in unmanaged memory constantly rising. This is the simple application I made to test: namespace TimerDebug { public partial class TimerDebug : ServiceBase { public TimerDebug() { InitializeComponent(); } protected override void OnStart(string[] args) { // Create Timer Timer MyTimer = new Timer(500);

问题 perl 5.8.9 Hello folks, I am successful in using DBI/DBD/ODBC to create a new table in an existing Access 2003 (.mdb) database with the following string: $q = "CREATE TABLE memoTestA (name TEXT, addr TEXT)"; # works but I can't figure out how to add a field of type MEMO ie $q = "CREATE TABLE memoTestB (name TEXT, addr TEXT, desc MEMO)"; # throws syntax error There must be a way - what is the trick? switching form using DBD::ODBC to Win32::OLE gets me past the "bad syntax" error thrown by the

问题 I'm using ADO.NET to connect to an Oracle DB through ODBC. Everything is working fine, besides binding parameters with a simple SQL query: Connection.Open(); IDbCommand command = Connection.CreateCommand(); command.CommandText = "SELECT length FROM activity_type WHERE name = :name_of_activity"; var parameter = command.CreateParameter(); parameter.ParameterName = ":name_of_activity"; parameter.Value = "Short_break"; command.Parameters.Add(parameter); int result = Convert.ToInt32(command

问题 I'm currently working with PHP and MS Access. I have a simple table with different data types. The connection to the database works good but, if I do a var_dump to the query, I notice that all data type are all converted to strings. If I use the same database with ASP I got the data types correct. The problem seems to be only with PHP and the ODBC driver. Is there any way to get those values with their correct data type? Any help would be greatly appreciated. 回答1: While it is true that an

问题 I'm on my way learning about PDO from phpro.org, and a little bit confuse. <?php try { $dbh = new PDO("odbc:Driver={Microsoft Access Driver (*.mdb)};Dbq=C:\pdo-tutorial.mdb;Uid=Admin"); } catch (PDOException $e) { echo $e->getMessage(); } ?> What is Uid? and what value should I enter?
