Connection String Options  

The connection string properties describe the various options that can be used to establish a connection.




The connection string can be set to a series of "option=value" pairs, separated by semicolons. If a connection string property value has special characters such as semicolons, single quotes, spaces, etc., then you must quote the value using either single or double quotes.

Connection options are case insensitive.

To specify a location to the database where the tables, views and stored procedures are located, set the Location.
