Sets the in-reply-to ID of this message.
|1||Message ID||VARCHAR(128). You can obtain the message ID from ml_qa_createmessage or ml_qa_getmessage.|
An in-reply-to ID is similar to the in-reply-to IDs that are used by email systems to track replies.
Typically you set the in-reply-to ID to be the message ID of the message to which this message is replying, if any.
A client can use the InReplyToID header field to link one message with another. A typical use is to link a response message with its request message.
You cannot alter this header after the message has been sent.
In the following example, when a message is received that contains a reply-to-address, a reply message is created and sent containing the message ID in the in-reply-to-id:
begin declare @msgid varchar(128); declare @rmsgid varchar(128); declare @replyaddr varchar(128); set @msgid = ml_qa_getmessage( 'myaddress' ); set @replyaddr = ml_qa_getreplyaddress( @msgid ); if @replyaddr is not null then set @rmsgid = ml_qa_createmessage(); call ml_qa_settextcontent( @rmsgid, 'message received' ); call ml_qa_setinreplytoid( @rmsgid, @msgid ); call ml_qa_putmessage( @rmsgid, @replyaddr ); end if; commit; end
