Question

我有3张如下表。

表A：（有一列员工ID）

Employee Id
   101
   102
   103

表B：（有一列EmployeeName）

EmpName
Sai
sarath
vijay

表C :(有一列DeptName）

DeptName**.
IT
ACCOUNTS
MANAGEMENT

这里我想将所有三个表列值插入一个临时表中。像

Create table #mytable (employeeid nvarchar(255),empname nvarchar(255),deptname nvarchar(255))

insert into #mytable (employeeid)

select employeeid from tableA
insert into #mytable (empname)

select empname from tableB
insert into #mytable (deptname)

select deptname from tableC

但是我的临时表（即）#mytable给了我下面的结果。

**Employeeid                Empname              DeptName**
    101                          null                  null
    102                          null                  null
    103                          null                  null
    null                        sai                    null
    null                       Sarath                  null
    null                        vijay                  null
    null                        null                   IT
    null                        null                    ACCOUNTS
    null                        null                    MANAGEMENT

但我想只显示数据行而不是空值。请给我任何建议，将所有三个表，即A，B，C一次插入临时表，即#mytable。并且只显示包含行的数据。

我尝试过如下查询

 insert into tb_MBUPSheetData123 ([BusinessStrategyMessaging],Capability,[DealSource],Language,LicenseType,[Proactive activity],[Proposal Type],RFXSolution,
   SLBusinessSolutionArea,SolutionForProposal,SupportingSolution,Conversations,TopicForProposal,SalesDeskAgentAlias)

values ((select [BusinessStrategyMessaging] from tb_MBUPSheetData where BusinessStrategyMessaging is not null),
(select [DealSource]  FROM tb_MBUPSheetData where DealSource is not null),
(select [Capability] FROM tb_MBUPSheetData where Capability is not null),
 (select [Language] FROM tb_MBUPSheetData where Language is not null)
 ,(select [LicenseType] FROM tb_MBUPSheetData where LicenseType is not null),

(select [Proactive activity]  FROM tb_MBUPSheetData where [Proactive activity] is not null),
(select [ProposalType] FROM tb_MBUPSheetData where [Proposal Type] is not null),
(select[RFXSolution] FROM tb_MBUPSheetData where RFXSolution is not null),
(select [SLBusinessSolutionArea] FROM tb_MBUPSheetData where SLBusinessSolutionArea is not null),
(select [SolutionForProposal]FROM tb_MBUPSheetData where SolutionForProposal is not null),
(select [SupportingSolution] FROM tb_MBUPSheetData  where SupportingSolution is not null),
 (select Conversations FROM tb_MBUPSheetData where Conversations is not null),
 (select [TopicForProposal] FROM tb_MBUPSheetData where TopicForProposal is not null),
 (select [SalesDeskAgentAlias]  FROM tb_MBUPSheetData where SalesDeskAgentAlias is not null))

但我收到的错误

子查询返回的值超过1。当子查询遵循=，！=，＆lt;，＆lt; =，＆gt;，＆gt; =或子查询用作表达式时，不允许这样做。声明已经终止。

任何建议......

Answer 1

首先，您的三个表必须具有外键关系，例如员工ID noe，您可以编写类似

的语法

insert into mytable(employeeid,empname,deptname) select a.Eamployee_Id,b.EmpName,c.DeptName from table_a a,table_b b,table_c c where a.Eamployee_Id=b.Eamployee_Id and a.Eamployee_Id=c.Eamployee_Id;

Answer 2

如果你想在#temp表中一次输入所有条目，你可以试试这个： -

insert into #mytable values(select employeeid from tableA where_condition,select empname from tableB where_condition,select deptname from tableC where_condition);

将多个表数据作为时间插入临时表
