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 PostgreSQL connection string for connecting to wikipedia.com with SSL and a connection timeout of 180 seconds:
|
|
|
|
DRIVER={PostgreSQL Unicode};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:
|
|
|
|
on the command line (as in: sqlplus scott/tiger@connection_string )
|
|
via environment variables ($TWO_TASK in Unix-like environments; %TWO_TASK% in Microsoft Windows environments)
|
|
in local configuration files (such as the default $ORACLE_HOME/network/admin.tnsnames.ora)
|
|
in LDAP-capable directory services
