关于临时表和声明表的问题。如果我更改临时表' ChangedData'和' PackageDatatoProcess'他们自己的变量' @ ChangedData'和' @ PackageDatatoProcess',我可以问我如何更改select into语句,因为我之前没有完成此操作。实际上我告诉我们可以声明表而不是使用select into,但只需要一些帮助:
select distinct * into #PackageDataToProcess from #ChangedData pp
outer apply (
select pk.Reference, pjl.PackageToJournalLinkId, j.CreatedDate, pccl.PackageCostChangeLogId from Jet2Holidays.dbo.Package pk
inner join Jet2Holidays.dbo.PackageToJournalLink pjl on pk.PackageId = pjl.PackageId
inner join Jet2Holidays.dbo.Journal j on pjl.JournalId = j.JournalId
and j.PrincipalName= iif(@AllowNonSupportChanges = 0, 'HolidaysSupport', j.PrincipalName)
inner join Jet2Holidays.dbo.BusinessProcess bp on pjl.BusinessProcessId = bp.BusinessProcessId
and bp.[Description] = iif(@AllowNonSupportChanges = 0, 'CallCentreAction', bp.[Description])
left outer join Jet2Holidays.dbo.PackageCostChangeLog pccl on pccl.PackageToJournalLinkId = pjl.PackageToJournalLinkId
where pk.Reference = pp.PackageReference
and pp.JournalID = pjl.JournalId
) as packageData
答案 0 :(得分:2)
首先,您声明变量表如下:
DECLARE @PackageDataToProcess TABLE
(
Reference UNIQUEIDENTIFIER
, PackageToJournalLinkId INT
, CreatedDate DATETIME
, PackageCostChangeLogId INT
, {other columns here}
)
DECLARE @ChangedData TABLE
(
Reference UNIQUEIDENTIFIER
, PackageToJournalLinkId INT
, CreatedDate DATETIME
, PackageCostChangeLogId INT
, {other columns here}
)
此时您可以像这样填充@ChangedData表:
INSERT @ChangedData ( Reference, PackageToJournalLinkId, CreatedDate, PackageCostChangeLogId, {other columns})
SELECT Reference, PackageToJournalLinkId, CreatedDate, PackageCostChangeLogId, {other columns}
FROM ChangedDataSource -- Table, Procedure, Function
然后您可以通过将@PackageDataToProcess替换为#PackageDataToProcess来运行您的代码。在这里再次略微重写(来自原文):
INSERT @PackageDataToProcess
select distinct pp.* from @ChangedData pp
outer apply (
select pk.Reference, pjl.PackageToJournalLinkId, j.CreatedDate, pccl.PackageCostChangeLogId from Jet2Holidays.dbo.Package pk
inner join Jet2Holidays.dbo.PackageToJournalLink pjl on pk.PackageId = pjl.PackageId
inner join Jet2Holidays.dbo.Journal j on pjl.JournalId = j.JournalId
and j.PrincipalName= iif(@AllowNonSupportChanges = 0, 'HolidaysSupport', j.PrincipalName)
inner join Jet2Holidays.dbo.BusinessProcess bp on pjl.BusinessProcessId = bp.BusinessProcessId
and bp.[Description] = iif(@AllowNonSupportChanges = 0, 'CallCentreAction', bp.[Description])
left outer join Jet2Holidays.dbo.PackageCostChangeLog pccl on pccl.PackageToJournalLinkId = pjl.PackageToJournalLinkId
where pk.Reference = pp.PackageReference
and pp.JournalID = pjl.JournalId
) as packageData
您声明的tabled将以与非全局临时表的方式类似的方式超出范围。
