New Comment:
Since I omitted double-quotes at the end of the query, here's the
corrected one:
$query="SELECT test_text FROM test WHERE test_id=2";

)
insert into TEST (TEST_VALUE) values ('5');
insert into TEST (TEST_VALUE,TEST_TEXT) values ('6','');
in PHP script:
...
$query="SELECT test_text FROM test WHERE test_id=2;
$res=mssql_query($query,$db);
Expected result:
----------------
Empty string.
Actual result:
--------------
