[PHP-DB] mssql_query returns a boolean false instead an empty recordset when the query doesn't match any record
Hi all, Maybe I didn't explain myself quite wel, so I wil repeat the queestion in other words. I would like to know which is the correct answer I should obtain from mssql_query. I have a server in which mssql_query is returning a false boolean when it should return an empty recordset (as is doing in the other server). In other words, the question is why I have a server in which mssql_query returns empty recordsets when the query doesn't match any record and I have installed a new one in which instead of an empty recordset I get a boolean valued to false. Which one is ok and what can be the problem with the other. I know I can test in each query if result is false or a resource but I have more than a hundred queries and I would like to have the knew server with the same behavour as the previous one, which it is also how I think that it should work. I'm sorry for the repetition of the topic, but I'm very interested in having a better solution than putting if's in each query. Thank you. Pablo smime.p7s Description: S/MIME Cryptographic Signature
[PHP-DB] mssql_query returns a boolean false instead an empty recordset when the 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
