affecting connections
When an application connects to a database, it uses a set of connection
parameters to define the connection. Connection parameters include
information such as the server name, the database name, and a user ID.
A keyword-value pair, of the form parameter=value, specifies each connection
parameter. For example, you specify the password connection parameter for
the default password as follows:
Password=sql
Connection parameters are assembled into connection strings. In a connection
string, a semicolon separates each connection parameter, as follows:
ServerName=host_asiqdemo;DatabaseName=asiqdemo
This chapter has many examples of connection strings, represented in the
following form:
parameter1 = value1
parameter2 = value2
...
This is equivalent to the following connection string:
parameter1 = value1 ; parameter2 = value2
