DubUrl

DubUrl provides a standard, URL style mechanism for parsing database connection strings and opening DbConnections for .NET. With DubUrl, you can parse and open URLs for popular databases such as Microsoft SQL Server, PostgreSQL, MySQL, SQLite3, Oracle Database and most of the other SQL databases. This project is inspired from the package dburl available in the GoLang ecosystem and is trying to match the aliases for portocols.

Database Connection URL Overview

Supported database connection URLs are of the form:

driver:alias://user:pass@host/dbname?opt1=a&opt2=b

Where:

Component	Description
alias	database type (see below)
driver	driver/provider name (only for odbc/oleodbc)
user	username
pass	password
host	host
dbname*	database, instance, or service name/ID to connect to
?opt1=...	additional database driver options (see respective SQL driver for available options)

^* for Microsoft SQL Server, /dbname can be /instance/dbname, where /instance is optional. For Oracle Database, /dbname is of the form /service/dbname where /service is the service name or SID, and /dbname is optional. Please see below for examples.

Quickstart

Database connection URLs in the above format can be parsed to a standard connection string with the [Parse] as such:

string connectionUrl = "mssql://{server}/{database_name}";
string connectionString = new ConnectionUrl(connectionUrl).Parse();

Additionally, a simple helper, [Open], is provided that will parse, open, and return a standard DbConnection.

string connectionUrl = "mssql://{server}/{database_name}";
IDbConnection connection = new ConnectionUrl(connectionUrl).Open();

If you don't want to open the connection but only return it and manage its state by yourself, use the function [Connect]

string connectionUrl = "mssql://{server}/{database_name}";
IDbConnection connection = new ConnectionUrl(connectionUrl).Connect();

Example URLs

The following are example database connection URLs that can be handled by [Parse], [Connect] and [Open]:

mssql://user:[email protected]/instance/dbname?keepAlive=10
oledb+mssql://user:pass@localhost/dbname

postgres://user:pass@localhost/dbname
odbc+postgres://user:pass@localhost:port/dbname?option1=

mysql://user:pass@localhost/dbname
oracle://user:[email protected]/sid
db2://user:pass@localhost/dbname

Installing

Install in the usual .NET fashion:

Install-Package DubUrl

To install the extension for OLEDB provider locators

Install-Package DubUrl.OleDb

To install the extension for ADOMD.NET data provider

Install-Package DubUrl.Adomd

Using

Check the first steps guide on the website.

Please note that DubUrl does not install actual drivers, and only provides a standard way to [Parse] respective database connection URLs then [Connect] or [Open] connections.
