Question

SQL 2005 Joins

Asked by: jdr0606

I'm struggling on how to extract a list by joining multiple tables without getting alot of duplicate values.

In the example below the IV00101 table is the items master with one entry for each item.
The second table has multiple entries for each item so I only want the match item and whose RCRDTYPE=1.
The remaiing tables typically have fewer items than in the master in one case is joined based on the iv00102 table.

What I'm looking for a result is one line per item in the item master and the results in the select as statements.

What am I doing wrong with my select and join?

Thanks


SELECT iv1.itemnmbr AS 'ItemNumber'
      ,iv1.itemdesc AS 'ItemDescription'
      --,iv1.itmshnam 'ItemShortName'
      ,iv3.planningleadtime as 'LeadTime'
      , HM5.HM_Currency_1 AS 'ListPrice'
      ,iv3.vnditnum 'VendorNumber'
      ,pm2.vendname AS 'VendorName'
      ,(case when ev6.pricegroup like '%SALE%' then 'Yes'
            else 'No' end
        ) as 'OnSale'
FROM iv00101 iv1
JOIN iv00102 iv2 ON iv2.ITEMNMBR = iv1.ITEMNMBR and iv2..RCRDTYPE=1
Left JOIN iv00103 iv3 ON iv3.itemnmbr = iv1.ITEMNMBR
Left  JOIN  eiv00600 ev6 ON ev6.itemnmbr = iv1.ITEMNMBR
Left  JOIN hm00500 hm5 ON hm5.itemnmbr = iv1.ITEMNMBR
Left  JOIN pm00200 pm2 ON pm2.VENDORID = iv2.PRIMVNDR
Left  join bm10300 bm1 on bm1.itemnmbr = iv1.ITEMNMBR

I was still getting some duplicates so I updated the statement but am now receiving errors.  The main change was for IV00103 which also has multiple items and ties back to iv00102 on the PRIMVNDR field.

The errors are:
Msg 4104, Level 16, State 1, Line 1
The multi-part identifier "iv2.primvndr" could not be bound.
Msg 207, Level 16, State 1, Line 16
Invalid column name 'PRIMVNDR'.
Msg 207, Level 16, State 1, Line 4
Invalid column name 'planningleadtime'.
Msg 207, Level 16, State 1, Line 6
Invalid column name 'vnditnum'.

The updated select is:

SELECT iv1.itemnmbr AS 'ItemNumber'
      ,iv1.itemdesc AS 'ItemDescription'
      --,iv1.itmshnam 'ItemShortName'
      ,iv3.planningleadtime as 'LeadTime'
      , HM5.HM_Currency_1 AS 'ListPrice'
      ,iv3.vnditnum 'VendorNumber'
      ,pm2.vendname AS 'VendorName'
      ,(case when ev6.pricegroup like '%SALE%' then 'Yes'
            else 'No' end
        ) as 'OnSale'
FROM iv00101 iv1
JOIN (select distinct ITEMNMBR from iv00102 where RCRDTYPE = 1) iv2 ON iv2.ITEMNMBR = iv1.ITEMNMBR
left JOIN (select distinct itemnmbr from iv00103 where vendorid=iv2.primvndr) iv3 ON iv3.itemnmbr = iv1.ITEMNMBR

That works much better, however I forgot to add one other condition.

I need to remove the join on bm10300 and instead need it to be used in a where statement.

i.e. the select should exclude items that are in the bm10300 table.

Thanks, You are excellent!
