Don't know this would help.
If you are using mssql to loop through a web page. Here is how to do it:
Suppose you want to select a few fields from t1 joining to t2

$numPerPage=10;
if(empty($offset))
  $offset=0;
if($next_x){
  $offset+=$numPerPage;
}
if($previous_x){
  $offset-=$numPerPage;
}

$qry_string = "SELECT DISTINCT TOP $numPerPage t1.field1, t1.field2 from t1 LEFT
JOIN t2 ON t2.field1=t1.field1
WHERE t2.another_field='specific_val'
AND t1.fields
NOT IN
(SELECT DISTINCT TOP $offset tmpT1.field1
FROM t1 AS tmpT1 LEFT
JOIN t2 ON t2.field1=tmpT1.field1
WHERE t2.another_field='specific_val'
)";

// then run the above $qry_string using the while loop
