CHAPTER 9. SQL Statements
To send native syntax to a remote server.
FORWARD TO server-name { sql-statement }
FORWARD TO [ server-name ]
None
The remote connection is set to AUTOCOMMIT (unchained) mode for the duration of the FORWARD TO session. Any work that was pending prior to the FORWARD TO statement is automatically committed.
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:
To send a statement to a remote server (syntax 1)
To place Adaptive Server Anywhere into passthrough mode for sending a series of statements to a remote server (syntax 2)
When establishing a connection to server-name on behalf of the user, the server uses:
A remote login alias set using CREATE EXTERNLOGIN, or
If a remote login alias is not set up, the name and password used to communicate with the Adaptive Server 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.
server-name is the name of the remote server.
sql-statement is a command in the remote server's native syntax. The command or group of commands is enclosed in curly brackets ({}).
When you specify a server_name, but do not specify a statement in the FORWARD TO query, your session enters passthrough mode, and all subsequent queries are passed directly to the remote server. To turn passthrough mode off, issue FORWARD TO without a server_name specification.
SQL/92 Entry-level feature.
Sybase Supported by Open Client/Open Server.
The following example shows a passthrough session with the remote server ase_prod:
FORWARD TO aseprod SELECT * from titles SELECT * from authors FORWARD TO
