Hi all,
I am working with a computer hardware asset database and I am trying to get
information out of it for each PC in my organisation.
Here is the basic table structure:
Table1 -> Table2 -> Table3
-> Table4 -> Table5
Table1 is the master, table2 and table4 a linking tables to table3 and
table5
This is what I am trying to do:
select table1.name, table3.TotalVis ibleMemory, table5.label from (LEFT JOINS
HERE)
I have successfully retrieved the information from table 3 using this SQL:
select table1.name, table3.TotalVis ibleMemorySize
from
(table1 LEFT OUTER JOIN table2 ON (table1.id$=tab le2.GroupCompon ent))
LEFT OUTER JOIN table3 ON (table2.PartCom ponent=table3.i d$)
order by table1.name;
NOW, if I wanted to add a field table5.label how would I add the 2 LEFT
OUTER statements to this SQL?
I hope someone can help.
Thanks,
Vypre 1 6928

I'm not sure why you're using an outer join between the linking table
and table3.
I'd try writing the query in the following way:
SELECT table1.name, table3.TotalVis ibleMemorySize, table5.label
FROM table1 LEFT OUTER JOIN
(table2 INNER JOIN table3 ON table2.PartComp onent = table3.id$)
ON table1.id$ = table2.GroupCom ponent
LEFT OUTER JOIN
(table4 INNER JOIN table5 ON table4.someFiel d = table5.id$)
ON table1.id$ = table4.someOthe rField
ORDER BY table1.name
Of course, replace someField and someOtherField with the actual fields
in table4 that you use to link to table1 and table5.
