Hi John,
tried your suggestion but I can't get it to work. This is because I don't
know how to set conditions in the following clauses (because there isn't
any)
and Table1.[condition for Changes1]
and Table2.[condition for Changes2]
and Table3.[condition for Changes3]
What values do you want for Changes1, Changes2, etc.? (How are you
selecting for them.)
Post your SQL here if you need further help.
--J
the result I've got was similar to the following (note the ID is pkey of
another table)
ID Changes1 Changes2 Changes3
---------------------------------------------------------
1 10.0 10.0 same as
1 10.3 10.3
1 12.2 12.2
2 31.0 31.0
3 1.02 1.02
3 4.9 4.9
thanks for your help anyway
Tony

Hello,
I can get a select result like the following: (SELECT ID,Changes FROM
mytable WHERE somecondition;)
ID Changes
-----------------
1 10.0
1 10.3
1 12.2
2 31.0
3 1.02
3 4.9
how can I get the above result sets into the following format (columns
'Changes1','Changes2',... are all from 'Changes')
ID Changes1 Changes2 Changes3 (limits of 5)
--------------------------------------------
1 10.0 10.3 12.2
2 31.0
3 1.02 4.9
I have got a method that works (I think) by first do a SELECT getting
DISTINCT id values and then foreach of these ID I do another SELECT to
get
the Changes values and then just massage the display.
Is there another way of doing this by using a single SQL query?
There may be a simpler way, but this should work:
select Table.ID,
Table1.Changes as Changes1,
Table2.Changes as Changes2,
Table3.Changes as Changes3
from Table,
Table as Table1,
Table as Table2,
Table as Table3
where Table.ID = Table1.ID
and Table.ID = Table2.ID
and Table.ID = Table3.ID
and Table1.[condition for Changes1]
and Table2.[condition for Changes2]
and Table3.[condition for Changes3]
order by table.ID
