SQL Server數(shù)據(jù)庫分組排序后的操作
作者:佚名 
  此文主要向大家闡述的是SQL Server數(shù)據(jù)庫分組排序后取每組的第 N 行數(shù)據(jù)的實際操作流程,以下就是文章的主要內(nèi)容描述。
 我們今天主要向大家愛描述的是SQL Server數(shù)據(jù)庫分組排序后取每組的第 N 行數(shù)據(jù)的實際操作步驟,首先我們是從select代碼示例開始的,假如你對其實際操作有興趣了解的話,你就可以通過以下的文章對其進行了解。
示例代碼select
- A.[DocNo] as [docno],
 - A1.[Item_ItemCode] as [itemcode],
 - A2.[LineNum] as [linenum],
 - A2.[ARBillLine] as [arbillLine],
 - A2.[Maturity] as [maturity],
 - A2.[AROCMoney_TotalMoney] as [totalmoney
 
示例代碼select
- A.[DocNo] as [docno],
 - A1.[Item_ItemCode] as [itemcode],
 - A2.[LineNum] as [linenum],
 - A2.[ARBillLine] as [arbillLine],
 - A2.[Maturity] as [maturity],
 - A2.[AROCMoney_TotalMoney] as [totalmoney],
 - A2.[AROCMoneyBalance_TotalMoney] as [totalBalanceMoney]
 - into #tempShouhuoFenqi
 - from AR_ARBillHead as A
 - left join [AR_ARBillLine] as A1 on (A.[ID] = A1.[ARBillHead])
 - left join [AR_ARInstalment] as A2 on (A1.[ID] = A2.[ARBillLine])
 - group by A.DocNo,A1.Item_ItemCode,A2.LineNum,A2.ARBillLine,A2.Maturity,A2.AROCMoney_TotalMoney,A2.AROCMoneyBalance_TotalMoney
 - -- select * from #tempShouhuoFenqi
 - -- drop table #tempShouhuoFenqi
 
合同起始日期:第期的日期
- select docno,arbillline,maturity1
 - into #tempMaturity1 from
 - (
 - select docno,arbillline
 - ,maturity as maturity1,
 - row_number() over
 - (partition by docno,arbillline --按docno,arbillline分組
 - order by maturity asc) as rowno --按maturity排序
 - from #tempShouhuoFenqi ) x
 - where x.rowno=2 --取分組排序后的第行
 - ---- select * from #tempMaturity1
 - ---- drop table #tempMaturity1
 
以上的相關內(nèi)容就是對SQL Server數(shù)據(jù)庫分組排序后取每組的第N行數(shù)據(jù)的介紹,望你能有所收獲。
