PHP Bug Type: ODBC related
Bug description: odbc_data_source returns avaible DNS, not information about argument
Description:
------------
Even though the documentation states that odbc_data_source "Returns
information about a current connection", it returns the list of avaible
DNS (after calling it several times).
This is a good feature, but maybe in a function called odbc_list_dns and
without the need for an argument with a previously established connection
(maybe ODBC internals require the connection to get them, I don't know).
What I expected after reading the docs about odbc_data_source was:
- odbc driver used (xtg for interbase6 in my case)
- underlying database (firebird 1.5rc8 in my case)
- perhaps other information, depending on the dbms
My code is:
----- begin --------------------------
<pre>
<?php
$conn = odbc_connect ($dns_name, $user, $pass);
if ($ds = @odbc_data_source ($conn, SQL_FETCH_FIRST)) {
do {
var_dump ($ds);
} while ($ds = @odbc_data_source ($conn, SQL_FETCH_NEXT));
}
?>
</pre>
----- end ----------------------------
The result (I'm from Spain):
----- begin --------------------------
array(2) {
["server"]=>
string(23) "Archivos de texto ASCII"
["description"]=>
string(36) "Microsoft Text Driver (*.txt; *.csv)"
}
array(2) {
["server"]=>
string(18) "MS Access Database"
["description"]=>
string(31) "Microsoft Access Driver (*.mdb)"
}
[...and some more]
----- end ----------------------------
You see? First, if this function is supposed to give information about the
connection and its data source, why do I need to call it many times? It's
not gonna change! Moreover, the information it gives the first time, with
SQL_FETCH_FIRST, does not correspond with the specified connection.
And, what is the need to specify if it's the first time or not
(SQL_FETCH_FIRST and SQL_FETCH_NEXT constants)? This second argument makes
no sense to me. Even in a odbc_list_dns function, I'd prefer the function
to return all the DNS as an array, and not having to call it several
times, inside a somewhat weird loop.
I think that correct function calls should be:
- odbc_data_source ($conn)
- odbc_list_dns ()
Again, I don't know the internals of ODBC. Maybe odbc_list_dns *needs* a
connection to work. Ok. But, please, no different arguments for the first
and the following calls.
Thank you very much. Keep on doing doing such a great job!
