I understand that SQLite3 does not operate under the client-server database application model, so I was wondering how one would actually connect to a "running" database server with a SQLite3 back.
Meaning if I were to have a database server running on Linux with a SQLite3 back, how would clients connect to this server? Would I have to use another RDBMS?
Thanks,
Jake
You don't have any database server running SQLlite3. You can just have applications using SQLlite3 (there is no client - server protocol involved). The data is in some files accessed by the libsqlite3 library linked inside the application. (so the data is local to the system running that application).
So by definition you cannot connect to a SQLlite3 database server. Such thing don't exist.
Read the http://www.sqlite.org/ front-page, which starts with
SQLite is a software library that implements a self-contained, serverless, zero-configuration, transactional SQL database engine.
And the wikipage sqllite
If you want to have a database server (with external, possibly remote, applications interacting thru a client-server protocol with it) switch to PostGreSQL, MariaDB, etc...
Clients that connect to SQLite "server" just use API that looks like connection. Library for "connection" is embedded into application.

Is it possible to (select query) of Microsoft Access database from my server where the MDB file is located in client pc (not in server)?
Global question: how to interact with client database (MS Accces) from my server(web site)???
You might want to rethink your setup:
Better have your database MDB on the server (Web server) since the server most likely to have a static IP address
Then you can have another database MDB on the client link to the Database MDB on the server (Web server) thru linked tables or ADO
This will be quite a challenge(redefining client/server setup), you better off going with a better DBMS on the server(Web site) like MySQL or MariaDB. Easy to setup and access remotely with MySQL connectors, from your client pc.
My client given code is programmed in c language to connect to Ingres Database in Unix environment.
This code is using API's such DBconnect(), DBExecSQL,DBRollback()....
I want to confirm that whether these API's are Ingres database specific API's?
Can I use these API's for connecting to Oracle DB.
If I cannot use those same API's to connect to Oracle DB, how to connect to Oracle Database from c program?
Thanks.
I can confirm they're not Ingres-specific API calls, which are things like IIapi_connect().
It's possible they're part of some 3rd party interface layer for which there's also an Oracle driver. Or they could be something they have written themselves and are in a library somewhere.
I have a scheduling software that has a database of clients, client pets, pets grooming styles, appointments and invoices.
The generic reports that are given with the software are not giving me the information that I need to go. Support from the software company is telling me to use Access to build the reports that I require.
I am not seeing how to connect to the software's DB to use in Access to generate my custom reports.
Any help or links to the information for this would be greatly appreciated.
Thanks in advance everybody
One of MS Access' unique features is connecting to external RDBMs' ( SQL Server, Oracle, Postgres, MySQL, SQLite) in complement to its default Jet/ACE SQL Engine. In fact, Access can connect to any other ODBC-compliant system even Quickbooks or your software assuming it has an ODBC API.
An .MDF is a SQL Server main database file but usually you do not connect directly to the file but the server instance. Most likely, you are required to connect Access to the SQL Server database the software sits on. In fact, you will be doing what the software does: connect to a backend database. No software or web/mobile app is without a database or data store of some kind.
MS Access backend setup is very easy with many online tutorials:
Find the SQL Server instance and all needed credentials (server address or host, port, schema, user, password).
Be sure to have an installed ODBC Driver (usually already available if SQL Server is installed) or check if software has a pre-defined DSN. Free MSSQL ODBC downloads are available online. Open odbcad32.exe to see current computer driver/DSN installs.
In a saved Access .accdb/.mdb database, under External Data tab in MSAccess.exe, click ODBC database (globe icon) where you walk through a wizard to connect to aforementioned Driver or DSN (machine or user). You can either import tables or link live tables which upon successful connection will prompt you to select the database tables.
From there you can use linked tables like any other local table within MS Access including forms, reports, macros, and modules.
In fact, knowing the ODBC connection you can work in most programming languages that maintain database APIs including Python, PHP, R, Perl, Java, C#, VB, even your everyday MS Excel to interact with scheduling software's data.
We have two Sql 2008 R2 database. First and main one is on-premise which is used by our stock management and accounting systems.
The second is for our web site and it is on a 3th party hosting firm and that database is updated manually by a standard XML file operation
(creating XML from on-premise database, sending it to web server, reading from XML file & insert/update/delete web database)
we need to get rid of that manual XML operation and sync that two databases automatically, but problem is our hosting firm does not allow "Replication" or "Linked Server" facilities on their "Sql Server" system. That's way we can not sync databases with these "Sql Server" facilities.
I am trying find out sync alternatives for that scenario without changing the hosting system.
What options can we use ?
Is Microsoft Sync Framework can be used for this scenario? ( I'm not sure if it is just for the Microsoft Azure Sql system)
Thanks…
if you're fine coding, then Sync Framework can do this.
Sync Framework can sync SQL Compact, Express, Server, Azure or LocalDB
But bear in mind that Sync Framework will need to create some Sync-related objects on your databases (triggers, stored procedures, tables, etc...)
It sounds like you need a hosting provider that provides these services.
It is typical for a hosting provider to provide an on-demand or always VPN connection to the production servers from the client location to the servers at the hosting location. Such a service is often needed for support of online systems. If you had such a connection then having SQL Server do syncs would be no problem.
Any major (Rack Space, Peer1, etc) provider would be able to set up such a system.
It probably won't be as inexpensive as your current provider.
Well if changing a provider is not an option, at list in the short term and you need something right now, you can always automate parts or all your current process.
For that you can at least use:
PowerShell (or even plain old cmd.exe) script(batch) and bcp.exe to export and import your files on both ends and PowerShell and ftp to transfer your files from one server to another.
SQLServer Integration Services on premises to export and send files via ftp to your hosting location. And SSIS to grab and import those files at your hosting location.
I'm developing a tool to synchronize SQL Server database with a PI System (OleDb).Each time there is a change in the PI System I need to update the values in SQL Server Database and vice-versa. Could you please provide me with the options possible and how it can be done.
Thanks,
M.K
At this time this can be done through the Relational Database (RDBMS via ODBC) Interface from OSI Soft.The interface allows bi-directional transfer of data between the PI System and any Relational Database Management System (RDBMS) that supports Open DataBase Connectivity (ODBC) drivers. The interface runs on Microsoft Windows operating systems, and is able to connect to any PI Server node available on the network.
I have used this interface and it is very stable. In the OSI PI YouTube Learning Channel, they have a series of videos where they take you step-by-step in the installation and configuration process of the interface.
Maybe you could use an EventPipe on your data and every time a new or edited event comes in you could push that out to the SQL Server.
