Hi Garrett,

Now the "multiple result sets" issue.

There's a bit of a terminology confusion. I'll explain a little.

TDS is a strictyly "conversational" protocol.

The client sends a message to the server, and the server sends a response,
typically:

client sends a query:

"select * from authors"

server sends a response, consisting of:

results metadata (describing the result set - number of columns and their
types, and order)
row data (one for each row returned - interpretable from the results
metadata)
done message.

The client needs to deal with this entire response, before initiating
another "call-response" pair.
It can process the response or throw all or part of it away, but it needs to
clear the conversational channel one way or another before proceeding.

This has implications for what the client can do. In particular the client
can't do the following (in pseudo-code):

send_query ("select au_id from authors")

while (get_returned_row(:my_author)) {

send_query("delete title_author where au_id = :my_author")

}

...at least not on the same database connection.
If you wan't to do this sort of processing, then you must open up two
connections to the database.

This is what is meant when in FREETDS terms we say that "multiple result
sets aren't supported" .
What we're really saying is that "multiple concurrent conversations on the
same database connection are not supported"

In the case of a query with a compute clause, a server response may contain
more than one set of results metadata, and we can (or should be able to)
handle that.


HTH,

Bill
