No, you seem to have missed my point entirely. So I'll explain in a
little more detail.
I run a stored procedure. Let's assume I run it from the interactive
utility and not from PHP for the moment.
> SP_SOMETHING_OR_OTHER PARAM1 PARAM2 PARAM3
The database returns:
foo bar
=== ===
10 20
30 40
field1 field2 field3
====== ====== ======
string bla 15
nothing bla 12
As you can see, it returns TWO result sets. One with two numeric
columns. The next with three columns, the first two string and the
last numeric.
This is, of course, just an example.
Now back to the web interface.
If I use PHP, I get only the first result set. That is, I write
something along the lines of:
$rs = sybase_query( "SP_SOMETHING_OR_OTHER PARAM1 PARAM2 PARAM3",
$conn );
while ( $row = sybase_fetch_row( $rs ) ) {
echo $row[0]; // and so on
}
This will only display the results of the first result set - the one
with the two fields, foo and bar.
There is no way for me to reach the second table generated by the
query. This is supposed to be the significant table.
Now, in ASP, there is something like
set rs = rs.NextResultSet
Which sets the rs to the second result set, the one with the three
fields of mixed types, at which point you loop, just like above, and
retrieve the new information. This method or an equivalent of it is
not in the PHP documented set of Sybase functions.
I hope I made myself clearer. And by the way, you don't have to sell
me on the uselessness of ASP, the general uselessness of Microsoft
etc. - I don't use any Microsoft products, even at work.
