Connection string


In computing, a connection string is a string that specifies information about a data source and the means of connecting to it. It is passed in code to an underlying driver or provider in order to initiate the connection. Whilst commonly used for a database connection, the data source could also be a spreadsheet or text file.
The connection string may include attributes such as the name of the driver, server and database, as well as security information such as user name and password.

Examples

This example shows a Postgres connection string for connecting to wikipedia.com with SSL and a connection timeout of 180 seconds:

DRIVER=;SERVER=www.wikipedia.com;SSL=true;SSLMode=require;DATABASE=wiki;UID=wikiuser;Connect Timeout=180;PWD=ashiknoor

Users of Oracle databases can specify connection strings:
