PHP Bug Type: MSSQL related
Bug description: crash with batches on zero row queries
Description:
------------
I executed mssql_query("...", $db, 50). The result was empty (no rows
returned), and there was a read from 0x00000000 when (I think)
mssql_fetch_assoc() executed.
Reproduce code:
---------------
I had no time to record the exact code, but it was something like this:
$q=mssql_query("select * from table", $db, 50);
do {
while ($row=mssql_fetch_assoc($q)) {
...
}
} while (mssql_fetch_batch($q)>0);
the table was empty. I then prepended
if (mssql_num_rows($q)>0)
and everything was fine.
Expected result:
----------------
nothing, the table was empty :)
Actual result:
--------------
a crash because of reading 0x00000000
