Use this statement to assign an alternate login name and password to be used when communicating with a remote server.
CREATE EXTERNLOGIN login-name TO remote-server REMOTE LOGIN remote-user [ IDENTIFIED BY remote-password ]
login-name specifies the local user login name. When using integrated logins, the login-name is the database user to which the Windows user or group is mapped.
TO clause The TO clause specifies the name of the remote server.
REMOTE LOGIN clause The REMOTE LOGIN clause specifies the user account on remote-server for the local user login-name.
IDENTIFIED BY clause The IDENTIFIED BY clause specifies the remote-password for remote-user. The remote-user and remote-password combination must be valid on the remote-server.
If you omit the IDENTIFIED BY clause, the password is sent to the remote server as NULL. However, if you specify IDENTIFIED BY "" (an empty string), then the password sent is the empty string.
By default, SQL Anywhere uses the names and passwords of its clients whenever it connects to a remote server on behalf of those clients. CREATE EXTERNLOGIN assigns an alternate login name and password to be used when communicating with a remote server.
The password is stored internally in encrypted form. The remote-server must be known to the local server by an entry in the ISYSSERVER table. See CREATE SERVER statement.
Sites with automatic password expiration should plan for periodic updates of passwords for external logins.
CREATE EXTERNLOGIN cannot be used from within a transaction.
Only users with DBA authority can add or modify an external login for login-name.
Not supported on Windows Mobile.
Automatic commit.
SQL/2003 Vendor extension.
