Well, that'll obviously be tgd.Constrained . . .

Question
sql help
Here is what I have:
SELECT DISTINCT tbm.MaterialNo, tgm.GroupingID, tbm.MaterialDescription, tbd.PrettyName, tgd.Constrained, tgd.DefaultSelect
FROM TOPS_GROUP_KEY_DETAIL LEFT OUTER JOIN
TOPS_GROUPING_MASTER AS tgm ON TOPS_GROUP_KEY_DETAIL.Grou
TOPS_BOM_MASTER AS tbm ON tgm.MaterialID = tbm.MaterialNo LEFT OUTER JOIN
TOPS_BOM_DETAIL AS tbd ON tgm.MaterialID = tbd.MaterialNo LEFT OUTER JOIN
TOPS_GROUPING_DETAIL AS tgd ON tgm.GroupingID = tgd.GroupingID
WHERE (TOPS_GROUP_KEY_DETAIL.Gro
It returns:
F145 5331 C_FJS_FL_FR_EA_OPNG_PLL PARALLEL OPENING NULL
F145 5331 C_FJS_FL_FR_EA_OPNG_PLL PARALLEL OPENING X NULL
I need only 1 record to show up. The field 'Constrained' which is represented by the 'X' flag in the above result set does not exist for every MaterialNo. How can I limit this to 1 record? If the constrained flag exists I want just that record else give me the other record.

Oh, sorry . . . last one . . . if you use TOP 1, you don't need distinct. Nota bene, this will only work if you really did mean that you want only one record. If you want to return a set of these rows which differ, but you want the constrained rows to take precedence, then you'll have to do it a different way. In that case, I'd probably just use a recursive join and some isnulls.
TNC
Yes I'll multiple records. The actual query is actually:
SELECT DISTINCT tbm.MaterialNo, tgm.GroupingID, tbm.MaterialDescription, tbd.PrettyName, tgd.Constrained, tgd.DefaultSelect
FROM TOPS_GROUP_KEY_DETAIL LEFT OUTER JOIN
TOPS_GROUPING_MASTER AS tgm ON TOPS_GROUP_KEY_DETAIL.Grou
TOPS_BOM_MASTER AS tbm ON tgm.MaterialID = tbm.MaterialNo LEFT OUTER JOIN
TOPS_BOM_DETAIL AS tbd ON tgm.MaterialID = tbd.MaterialNo LEFT OUTER JOIN
TOPS_GROUPING_DETAIL AS tgd ON tgm.GroupingID = tgd.GroupingID
WHERE (TOPS_GROUP_KEY_DETAIL.Gro
I'd probably use the join then. In pseudo-code . . .
SELECT DISTINCT
ID,
Description = ISNULL(Constrained.Descrip
Group = ISNULL(Constrained.Group, NotConstrained.Group)
FROM MyTable AS NotConstrained
LEFT JOIN MyTable AS Constrained
ON NotConstrained.ID = Constrained.ID
WHERE
Constrained.Constrained = 'x' AND
NotConstrained.Constrained
Does that make sense?
TNC
like this ?
SELECT distinct tbm.MaterialNo
, tgm.GroupingID
, tbm.MaterialDescription
, tbd.PrettyName
, case when tgd.const is null then ' ' else 'x' end as Constrained
, case when tgd.const is null then tgd.Unconst else tgd.const end as DefaultSelect
FROM TOPS_GROUP_KEY_DETAIL
LEFT OUTER JOIN TOPS_GROUPING_MASTER AS tgm
ON TOPS_GROUP_KEY_DETAIL.Grou
LEFT OUTER JOIN TOPS_BOM_MASTER AS tbm
ON tgm.MaterialID = tbm.MaterialNo
LEFT OUTER JOIN TOPS_BOM_DETAIL AS tbd
ON tgm.MaterialID = tbd.MaterialNo
LEFT OUTER JOIN
(select groupingID
,max(case when constrained = 'x' then defaultselect else null end) as const
,max(case when constrained = 'x' then null else defaultselect end) as UNconst
From TOPS_GROUPING_DETAIL
group by groupingid
) AS tgd
ON tgm.GroupingID = tgd.GroupingID
WHERE TOPS_GROUP_KEY_DETAIL.Grou
AND tbm.MaterialNo = 'F145'
btw the
AND tbm.MaterialNo = 'F145'
is in effect making the tbm join into an inner join... is that what you intended?
