以下SQL 查询不返回MS Access 中的 LEFT JOIN 的数据。
SELECT * FROM
(
SELECT Operation_Part.PPC,
Operation_Part.TargetOperationsPerHour as JPH,
Operation_Part.Misc1 as [JPh Alt 1],
STR(Operation_Part.SeqNr) as Sequence,
Operation_Part.idPart,
Operation_Part.idOperationPart,
Operation.OperationType as Operation,
tblOperationType.OperationType as [Operation Type]
FROM tblOperationType
RIGHT JOIN (Operation INNER JOIN Operation_Part ON Operation.idOperation = Operation_Part.idOperation)
ON tblOperationType.idOpType = Operation.OperationTID
WHERE Operation_Part.VsbLDq = 0
AND Operation_Part.idPart <> 0 AND Operation_Part.idPart = 1271)
AS [AA]
LEFT JOIN (SELECT Sum([Cptotal]) AS DownTime,
TransactionDetail.idPart,
STR(TransactionDetail.seq_number) as Sequence
FROM ([Transaction] INNER JOIN TransactionDetail ON [Transaction].idTransaction = TransactionDetail.idTransaction)
WHERE [Transaction].idTransactionType=29
AND TransactionDetail.WorkOrderNumber = 'PR23144'
GROUP BY TransactionDetail.idPart, STR(TransactionDetail.seq_number))
AS [EE]
ON AA.idPart = EE.idPart AND EE.Sequence=AA.Sequence
在 SQL Server 中,查询确实根据需要返回 1.08 的停机时间值(见下图)。
