odbc

问题 I have installed datastax ODBC driver for cassndra and also i have created keyspace and some tables using cql 3. But ODBC driver is not showing up those tables. Also in odbc documentation i read that the driver does not currently support version 3.0 of the Cassandra Query Language (CQL3) and the driver will not recognize keyspaces and column families that are defined with CQL 3. So in order to use cql 2 i am using following command which is suggested in driver documentation: ...\cqlsh” -2 But

问题 We're trying to insert data into a clipper database file (DBF file with NTX index file). For a variety of reasons, we cannot change the database format. We are currently seeing two issues: With our existing code, we are not able to update or utilize the NTX index file (I believe). We would like to be able to do this. Do you know of an OLE or ODBC driver that can do this? We are able to insert a row into the clipper database file (DBF) as long as we do not include a date. If we include a date,

问题 I am writing an application in C# (.NET 4.0) which has to integrate with another, much older application. Part of the requirement is that my program must read data from three Btrieve files. I can assume that these Btrieve data files will already exist on the computers where my program is installed, and I can also assume that Pervasive PSQL V9 will also be installed and the relational and transactional service programs are running. I have the associated DDF files, and I can install them as

问题 Lately I've been trying to connect a PostgreSQL 9.6 database on my C# project but I've been struggling setting up the connection string correctly due to "Keyword not supported:driver". After having read tons of information, I downloaded the ODBC.NET, I registered PostgreSQL in ODBC Data Sources (32x), referenced the Microsoft.Data.Odbc.dll in my project's directory and managed to have a successful connection with my database in the Visual Studio's Ultimate 2013, but when it came to accessing

问题 I have a PHP application that uses the ODBC functions for database access. My DBA recently discovered that the application is not closings its database connections, resulting in numerous invalid connections that are in a TIME_WAIT state. We have checked the code and I am doing an odbc_close_all call in every script, plus even if I wasn't then the connection should close at the end of the script anyway. There are no long running scripts holding on to their connections Has anyone seen anything

问题 I found out about the freeTDS which can be used here, but there are doubts about its stability in the production environment. Is there any other way to interactive with MSSQL Server from Solaris besides using ODBC driver? 回答1: Don't know of any other way. We're using unixODBC + freeTDS + DBD::Sybase in a production environment. It can be fiddly setting it up, but we have no problems with stability. It is possible to use FreeTDS directly and bypass unixODBC. 来源： https://stackoverflow.com

问题 On my Windows box I can list user and system ODBC dsns. For example: In my code I can connect to a database by using the name of a data source. For example: QSqlDatabase db = QSqlDatabase::addDatabase("QODBC"); db.setDatabaseName("M10-Server-Production"); I would like to obtain the list of data source names, both user and system, filter them to include only the ones suitable for my application, in this example they will start with "M10-Server", then offer the list to the user so the user can
