Jeff,

Then do it with 2 queries,
SELECT @d := MAX( datestamp )
FROM table2
WHERE parentID = X;
SELECT *
FROM table2
WHERE parentID = X AND [EMAIL PROTECTED];

Jeff,

Something like ...

SELECT *
FROM table2 AS a
WHERE datestamp = (
  SELECT MAX( b.datestamp )
  FROM table2 AS b
  WHERE a.parentID = b.parentID
);

I have a table that contains records that link back to a 
      
main talbe in 
    
a many to one configuration linked by table1.id = table2.parentid

Table1 (one)
Table2 (many)

I want to pull the latest records from table2 for each 
      
record in table1 
    
where certain criteria applie.

So, if record 100 in table1 links to 5 corresponding records 
      
in table2, 
    
I want to pull the latest record from table2 where table2.parentid = 
100 and table2.user not like 'john'

There is a datestamp field in table2.

I just can't figure out how to do this.

Thanks,

Jeff
