He needs to check whether the query worked before he attempts to access the
data
$result = mssql_query($query);
if (mssql_errno) != 0)
{
echo "error in query :". mssql_error();
die();
}

you can try this
while ($row = @mssql_fetch_array($result, MSSQL_ASSOC))
{
if(!$row) {
continue;
}
else {
//process each registry from the query
}
}

Subject: mssql_query returns a boolean false instead an empty
recordset whenthe query doesn't match any record
Hi all,
I'm moving my intranet pages from one server to a new one. In the
first server everything works ok but in the new one we are having
problems because every time that we are expecting a recordset and it
should be empty because the query doesn't match any record it is return
a boolean valued to false and we get this error when we call
mssql_fetch_row:
Warning: mssql_fetch_array(): supplied argument is not a valid MS
SQL-result resource
The code we are using is something like this:
$db = @mssql_connect("SERVER","USER","PASS") or die("I can't connect
to server");
mssql_select_db("DATABASE");
$query = "SELECT * FROM table WHERE false";
$result = mssql_query($query);
while ($row = mssql_fetch_array($result, MSSQL_ASSOC))
{
//process each registry from the query
}
Everything works fine when the query match at least a record but
mssql_query doesn't return a recordset when it should return an empty one.
We have a debian stable installation with php version 4.3.10-16 and
freetds-dev 0.63-2. To obtain freetds module we configured and
compiled php with "../configure --with-mssql=shared" and "copied with
cp modules/mssql.so /usr/lib/php4/20020429/". I know it could be a bit
strange doing things in this way but it was the one I got to have a
stable debian and apache and php and freetds installed with packages.
I hope there is someone who could help me.
Pablo
