表联接问题。。。很基础
生产单表
SQL code
CREATE TABLE [TProductionOrder] (
    [Fid] [int] IDENTITY (1, 1) NOT NULL ,
    [FProductionOrderNo] [nvarchar] (50) COLLATE Chinese_PRC_CI_AS NULL ,
    [FOrderAdmin_PersonId] [int] NULL CONSTRAINT [DF__TProducti__FOrde__73BA3083] DEFAULT (0),
    [FDevelopStateId] [int] NULL CONSTRAINT [DF__TProducti__FDeve__74AE54BC] DEFAULT (0),
    [FProductionPrgoressId] [int] NULL CONSTRAINT [DF__TProducti__FProd__75A278F5] DEFAULT (0),
    [FProductId] [int] NULL CONSTRAINT [DF__TProducti__FProd__76969D2E] DEFAULT (0),
    [FCustomerModelId] [int] NULL CONSTRAINT [DF__TProducti__FCust__778AC167] DEFAULT (0),
    [FProductionNum] [int] NULL CONSTRAINT [DF__TProducti__FProd__787EE5A0] DEFAULT (0),
    [FRequireTime] [datetime] NULL ,
    [FProductionAddTimer] [datetime] NULL ,
    [FTradeAuditer_PersonId] [int] NULL CONSTRAINT [DF__TProducti__FTrad__797309D9] DEFAULT (0),
    [FTradeStateId] [int] NULL CONSTRAINT [DF__TProducti__FTrad__7A672E12] DEFAULT (0),
    [FTradeAuditTime] [datetime] NULL ,
    [FFinishTime] [datetime] NULL ,
    [FRemark] [nvarchar] (50) COLLATE Chinese_PRC_CI_AS NULL ,
    [Fverify_PersonId] [int] NULL CONSTRAINT [DF__TProducti__Fveri__7B5B524B] DEFAULT (0),
    [FVerify_timer] [datetime] NULL ,
    [FSingleValue] [money] NULL CONSTRAINT [DF__TProducti__FSing__7C4F7684] DEFAULT (0),
    [FSingleValue_PersonId] [int] NULL CONSTRAINT [DF__TProducti__FSing__7D439ABD] DEFAULT (0),
    [FSingleValueTimer] [datetime] NULL ,
    [FInvaild] [bit] NOT NULL CONSTRAINT [DF__TProducti__FInva__7E37BEF6] DEFAULT (0),
    [FKitCost] [money] NULL CONSTRAINT [DF__TProducti__FKitC__7F2BE32F] DEFAULT (0),
    [FProductionCost] [money] NULL CONSTRAINT [DF__TProducti__FProd__00200768] DEFAULT (0),
    CONSTRAINT [aaaaaTProductionOrder_PK] PRIMARY KEY  NONCLUSTERED 
    (
        [Fid]
    )  ON [PRIMARY] 
) ON [PRIMARY]
GO



人员表
SQL code
CREATE TABLE [TPerson] (
    [Fid] [int] IDENTITY (1, 1) NOT NULL ,
    [FPersonName] [nvarchar] (50) COLLATE Chinese_PRC_CI_AS NULL ,
    [FDepartmentId] [int] NULL CONSTRAINT [DF__TPerson__FDepart__412EB0B6] DEFAULT (0),
    [FPermissionId] [int] NULL CONSTRAINT [DF__TPerson__FPermis__4222D4EF] DEFAULT (0),
    [FPositionId] [int] NULL CONSTRAINT [DF__TPerson__FPositi__4316F928] DEFAULT (0),
    [FMachineAddr] [nvarchar] (50) COLLATE Chinese_PRC_CI_AS NULL ,
    [FInvaild] [bit] NOT NULL CONSTRAINT [DF__TPerson__FInvail__440B1D61] DEFAULT (0),
    CONSTRAINT [aaaaaTPerson_PK] PRIMARY KEY  NONCLUSTERED 
    (
        [Fid]
    )  ON [PRIMARY] 
) ON [PRIMARY]

用生产单表中的 [FOrderAdmin_PersonId] , [FTradeAuditer_PersonId] ,[Fverify_PersonId] ,[FSingleValue_PersonId]  都联结到 人员表的怎么写

用 select 子查询貌似可以,用联接,我不会 - -,求教
GO


------解决方案--------------------
SQL code

select * from TProductionOrder t1 
left join TPerson t2 on t1.FOrderAdmin_PersonId=t2.Fid
left join TPerson t3 on t1.FTradeAuditer_PersonId=t3.Fid
left join TPerson t4 on t1.Fverify_PersonId=t4.Fid
left join TPerson t5 on t1.FSingleValue_PersonId=t5.Fid

------解决方案--------------------
可以, 你就 t1.字段1,t2.字段2,t2.字段……
