FORWARD TO statement

FORWARD TO server-name sql-statement

FORWARD TO [ server-name ]

server-name The name of the remote server.
sql-statement A command in the native SQL syntax of the remote server. The command or group of commands is enclosed in curly brackets ({}) or single quotes.

The FORWARD TO statement enables users to specify the server to which a passthrough connection is required. The statement can be used in two ways:

Syntax 1 Send a single statement to a remote server.
Syntax 2 Place SQL Anywhere into passthrough mode for sending a series of statements to a remote server. All subsequent statements are passed directly to the remote server. To turn passthrough mode off, execute FORWARD TO without a server-name specification.
If you encounter an error from the remote server while in passthrough mode, you must still execute a FORWARD TO statement to turn passthrough off.

When establishing a connection to server-name on behalf of the user, the database server uses one of the following:

A remote login alias set using CREATE EXTERNLOGIN
If a remote login alias is not set up, the name and password used to communicate with SQL Anywhere

If the connection cannot be made to the server specified, the reason is contained in a message returned to the user.

After statements are passed to the requested server, any results are converted into a form that can be recognized by the client program.

Note

The FORWARD TO statement is a server directive and cannot be used in stored procedures, triggers, events, or batches.

None

The remote connection is set to AUTOCOMMIT (unchained) mode for the duration of the FORWARD TO session. Any work that was pending before the FORWARD TO statement is automatically committed.

PASSTHROUGH statement [SQL Remote]

The following example sends a SQL statement to the remote server RemoteASE:

FORWARD TO RemoteASE { SELECT * FROM titles };

The following example shows a passthrough session with the remote server aseprod:

FORWARD TO aseprod
  SELECT * FROM titles
      SELECT * FROM authors
FORWARD TO;
