I have my windows 10 pc with ODBC datasource as my_odbc
This will connect to my remote informix server.
So for I am using this odbc for my local as well as php website development.
I want to use Adonis Js which uses knex.
How to give database connection properties, as to that of mysql, pg, mssql etc.
using odbc data source.
my connection is "DSN=my_odbc;UID=vijayan;PWD=vijayan;"
No.
But you can write your own ODBC client. There was some initial work done for it, but nowadays all new dialects should be added as separate npm modules like described in CONTRIBUTING.md https://github.com/tgriesser/knex/blob/master/CONTRIBUTING.md#i-would-like-to-add-support-for-new-dialect-to-knex-is-it-possible
(I'm not going to copy-paste that boilerplate code here, because it is more probable that knex changes and that linked document changes in compared to knex github getting offline)
Initial work that was done for the support is found here: https://github.com/tgriesser/knex/pull/2116

I need to connect to a .fdb file (Navision database file 2009) through C#. Can anyone explain how can I connect to this file using ODBC/NODBC?
I have tried these links but found nothing useful.

I haven't done it for C#, but Python. It all boils down to the following steps:
Install Navision ODBC Driver which is part of the Navision 2009 installation package.
Set up an ODBC connection to your Navision server. (The ODBC Driver also has a connection test included)
Use any ODBC library to connect to the ODBC DSN created in step 2.
Use regular SQL syntax to communicate with the database
edit/p.s.: Reading your question again. I think it's possible you are lacking the server part. As far as I know, you will need a running Navision server to interact with the fdb file.
We've just transitioned to using XAMPP which uses the open source fork of MySQL, MariaDB.
I've always used MySQL and the corresponding ODBC connector.
Do I need to change my code to work with MariaDB and if so do NI recommend an ODBC for MariaDB?
There is almost no difference between (same versions of) MariaDB and MySQL. You should even be able to reuse the same connectors.
However, you might want to use MariaDB's own connectors, at least for new systems.
For the same reason, there should be no changes necessary for your LabVIEW code.
I'm trying to create a database using Scala and SQLite. I'm using Slick as the library for the SQLite.
I've been googling around for hours and still can't figure out how to get this working. I have eclipse project with Slick installed. I'm trying to instanciate the database with
val db = Database.forUrl("url",driver = "org.SQLite.Driver")
I have no idea what to put in the url. I'm not very sure about the driver part either. Should I use that one or does "scala.slick.driver.SQLiteDriver" work too? Or does it even matter?
I'm really confused about all this.Any help is appreciated
Thanks!
JDBC relies on drivers that implement the JDBC API, and provide access to the low-level functionality of working with particular databases.
URLs are how you tell a JDBC driver which database you want to connect to. The first part of the URL is always jdbc:<driverId>:, where driverId is the specific name that the driver expects to see (e.g. postgresql, mysql or, in your case sqlite.) The format of the URL after the driver ID is specific to the particular driver implementation. With mysql and postgres, where you typically connect over TCP to the database server, you'll see a format like this:
jdbc:mysql://dbserver:dbport/databaseName
jdbc:postgresql://dbserver:dbport/databaseName
But, since SQLite is an in-process, local database, the part of the URL after the driver ID is just a filesystem path, like so:
jdbc:sqlite:/home/me/my-db-file.sqlite
I am new with Visio. Is it possible to generate an empty database from a database scheme? I am trying to generate a SQLite database from a Visio database scheme. I have tried to use reverse engineering with different SQLite drivers but could never see any tables to select in the reverse engineer wizard......
BTW, Is there any other tools that could build a SQLite database easier? I tried SQLite Manager, SQLite2009 pro enterprise manager. Either of them seems to be very user friendly. Also tried OsenXP Suite which did not work at all either...
Hope this could help
there is an answer here

seems you have to install ODBC driver
I've also tried using MySQL database, and need ODBC to connect to VISIO. The steps are here
http://sajjadhossain.com/2009/02/12/reverse-engineering-mysql-database-with-microsoft-visio/
Maybe the step is same because using ODBC
Unfortunately, I found error, if the table name is longer than 16 characters, then the visio will error.
What I want is a Powerbuilder application that runs on Windows that runs from a CD (or some other external disk) that can read from an ASA database whose file is located on the same disk. But I want to do so without deploying the ODBC or OLEDB drivers. That is, I do not want to have to copy the driver files to the client's hard disk or add any registry entries. Is this possible?
In the Powerbuilder and ASA documentation they mention something about "embedded database connections" and supposedly you can specify the executable for the database server in the connection string. But that was no help.
When you attempt to connect to a database and "ODBC" is specified for the DBMS property of the transaction object, PowerBuilder is going to want to start loading drivers and looking to an ODBC datasource for the driver's info.
The only thing I can think to try, is to create all the registry entries at run time and point them to the driver files and the .db file on the CD. You might be able to make things easier with a file based datasource on the CD already, but you'll still need to create registry entries to setup the driver details. Then you can remove all those entries when you disconnect/close the application. I don't think you can do this completely without registry entries.
You do have to deploy the ODBC driver, that's how PB talks to SQL Anywhere. You dont have to create a DNS entry though, you can usr a DNSless connection.

Since you aren't getting much feedback I thought I'd offer this. I've done this with MS Access, but MS Access is much easier to connect to and most Windows PC's are able to connect via File based DSN.
You definitely want to avoid ODBC if at all possible look for File based DSN in ASA, but because it is more of a full database engine I doubt it is possible without ODBC and setting up ODBC via Registry Entries is possible but no fun at all especially if your clients are running different versions of Windows.
Here is the connect string I used for something similar but MS Access. I choose Access for this exact reason, it was for a RPG program and I wanted a database but didn't want to mess with ODBC.
Sample:
"Connectstring='Driver={Microsoft Access Driver
(*.mdb)};UID=abc;PWD=123; Dbq=C:\Program Files\Mafia Manager\mm.mdb;
Exclusive=1;'"
