Question

在分配外键时，我在SQL Server 2014中遇到以下tSQL问题。有人可以帮我理解什么是不正确的吗？谢谢 - JT

    create table dbo.tbl_Util_Cost
    (
    chr_Grade   nchar(10)    not null Primary Key,
    pct_Target  decimal(18, 2)  not null,
    mon_Cost_Per_Hour   money   not null,
    dec_Daily_Hours decimal(18, 1)  not null
    );

    create table dbo.tbl_Team_Details
   (
     num_Personal_Number    numeric(18, 0)  not null,
     chr_Name   nchar(30)    not null,
     chr_Employee_Grade nchar(10)    not null ,
     dt_Start_Date date not null,
     dt_End_Date date   not null,
     foreign key fk_Team_Details1  ( chr_Employee_Grade) references dbo.tbl_Util_Cost (chr_Grade)   
    );

我在外键上遇到以下错误 -

Msg 102，Level 15，State 1，Line 11语法不正确 'fk_Team_Details1'

请指教！

Answer 1

你的语法错了。以下是正确语法的示例：

CONSTRAINT fk_Team_Details1 FOREIGN KEY（chr_Employee_Grade）参考文献dbo.tbl_Util_Cost（chr_Grade）

Answer 2

替换

foreign key fk_Team_Details1  
( chr_Employee_Grade) references dbo.tbl_Util_Cost (chr_Grade)

带

 constraint fk_Team_Details1  
 foreign key (chr_Employee_Grade) references dbo.tbl_Util_Cost (chr_Grade)

完整的脚本：

create table dbo.tbl_Util_Cost
(
chr_Grade   nchar(10)    not null Primary Key,
pct_Target  decimal(18, 2)  not null,
mon_Cost_Per_Hour   money   not null,
dec_Daily_Hours decimal(18, 1)  not null
);

create table dbo.tbl_Team_Details
(
 num_Personal_Number    numeric(18, 0)  not null,
 chr_Name   nchar(30)    not null,
 chr_Employee_Grade nchar(10)    not null ,
 dt_Start_Date date not null,
 dt_End_Date date   not null,
 constraint fk_Team_Details1  foreign key ( chr_Employee_Grade) references dbo.tbl_Util_Cost (chr_Grade)   
);

Answer 3

在添加Foriegn Key时修改第二个表创建

  constraint fk_Team_Details1  foreign key  
 ( chr_Employee_Grade) references dbo.tbl_Util_Cost (chr_Grade)

Answer 4

你去吧

create table dbo.tbl_Util_Cost
(
chr_Grade   nchar(10)    not null Primary Key,
pct_Target  decimal(18, 2)  not null,
mon_Cost_Per_Hour   money   not null,
dec_Daily_Hours decimal(18, 1)  not null
);

create table dbo.tbl_Team_Details
(
 num_Personal_Number    numeric(18, 0)  not null,
 chr_Name   nchar(30)    not null,
 chr_Employee_Grade nchar(10)    not null ,
 dt_Start_Date date not null,
 dt_End_Date date   not null,
 constraint fk_Team_Details1  foreign key ( chr_Employee_Grade) references dbo.tbl_Util_Cost (chr_Grade)   
);
