Question

我有这四个表：

SELECT [B_Key]
  ,[B_FiscalYear]
  ,[B_OrgCode]
  ,[B_SubObject]
  ,[B_Explanation]
  ,[B_CIPrefNo]
  ,[B_OrgBudgetAmt]
  ,[B_BudgetAmt]
  ,[B_Initials]
FROM [NAOLI].[dbo].[BudgetTbl]

SELECT [F_Fykey]
  ,[F_FiscalYear]
  ,[F_Year]
FROM [NAOLI].[dbo].[codeFiscalYearTbl]

SELECT [O_OrgKey]
  ,[O_OrgCode]
  ,[O_OrgDesc]
  ,[O_Divisions]
FROM [NAOLI].[dbo].[codeOrgCodeTbl]

SELECT [S_SubKey]
  ,[S_SubObject]
  ,[S_SubDescrip]
FROM [NAOLI].[dbo].[codeSubObjectTbl]

我需要在这些表格中组合不同的信息，以便制作以下信息表：

   [B_FiscalYear]
  ,[O_OrgCode]
  ,[O_OrgDesc]
  ,[S_SubObject]
  ,[S_SubDescrip]
  ,[B_BudgetAmt]
  ,[B_Initials]
  ,[B_CIPrefNo]
  ,[B_OrgBudgetAmt]

我尝试了下面的查询，但它返回了20750条记录中的0条..我该如何做到这一点？感谢

SELECT [B_FiscalYear]
  ,[B_OrgCode]
  ,[O_OrgDesc]
  ,[B_SubObject]
  ,[S_SubDescrip]
  ,[B_BudgetAmt]
  ,[B_Initials]
  ,[B_CIPrefNo]
  ,[B_OrgBudgetAmt]

INTO dbo.BudgetsTbl
  FROM [BudgetTbl] BT, [codeFiscalYearTbl] FY, [codeOrgCodeTbl] OC, [codeSubObjectTbl] SO
WHERE BT.B_FiscalYear = FY.F_Year and BT.B_OrgCode = OC.O_OrgCode and BT.B_SubObject = SO.S_SubObject

Answer 1

联接应该是这样的：

SELECT [B_FiscalYear]
  ,[B_OrgCode]
  ,[O_OrgDesc]
  ,[B_SubObject]
  ,[S_SubDescrip]
  ,[B_BudgetAmt]
  ,[B_Initials]
  ,[B_CIPrefNo]
  ,[B_OrgBudgetAmt]
FROM BudgetTbl BT
JOIN codeFiscalYearTbl FY ON BT.B_FiscalYear = FY.F_Year
JOIN codeOrgCodeTbl OC ON BT.B_OrgCode = OC.O_OrgCode
JOIN codeSubObjectTbl SO ON BT.B_SubObject = SO.S_SubObject

您可以查看http://sqlfiddle.com/#!3/8ff6b/7了解详情。如果需要，您还可以添加左连接。

正确的连接语法是：

SELECT [B_FiscalYear], [B_OrgCode], [O_OrgDesc], [B_SubObject], [S_SubDescrip],
       [B_BudgetAmt], [B_Initials], [B_CIPrefNo], [B_OrgBudgetAmt]
INTO dbo.BudgetsTbl
FROM BudgetTbl BT join
     codeFiscalYearTbl FY
     on BT.B_FiscalYear = FY.F_Year  join
     codeOrgCodeTbl OC
     on BT.B_OrgCode = OC.O_OrgCode join
     codeSubObjectTbl SO
     on BT.B_SubObject = SO.S_SubObject

据推测，您的一个或多个查找表为空。如果您想要所有行，请在上面的查询中将“join”替换为“left outer join”。
