CHAPTER 2 Running Adaptive Server IQ

89

Connecting from a client application

A client application can connect to a database using an integrated login in one
of the following ways:

Set the INTEGRATED parameter in the list of connection parameters to

yes

.

Specify neither a user ID nor a password in the connection string or
connection dialog. This method is available only for Embedded SQL
applications, including the Adaptive Server IQ administration utilities.

If INTEGRATED=

yes

is specified in the connection string, an integrated login

is attempted. If the connection attempt fails and the LOGIN_MODE database
option is set to

Mixed

, the server attempts a standard login.

If an attempt to connect to a database is made without providing a user ID or
password, an integrated login is attempted. The attempt succeeds or fails
depending on whether the current user profile name matches a integrated login
mapping in the database.

Interactive SQL
Examples

For example, a connection attempt using the following Interactive SQL
statement will succeed, providing the user has logged on with a user profile
name that matches a integrated login mapping in a default database of a server:

CONNECT USING ’INTEGRATED=yes’

The following DBISQL statement.

CONNECT

can connect to a database if all the following are true:

A server is currently running.

The default database on the current server is enabled to accept integrated
login connections.

An integrated login mapping has been created that matches the current
user's user profile name.

If the user is prompted with a dialog box by the server for more connection
information (such as occurs when using the DBISQL utility), the user
clicks OK without providing more information.

Integrated logins via
ODBC

A client application connecting to a database via ODBC can use an integrated
login by including the Integrated parameter among other attributes in its Data
Source configuration.
