如何在具有两个表参数的存储过程中编写多个插入语句

Question

I have two tables

Employee---->Id(identity),FN,LN,Address

EmpContact--->Id(identity),Empid(Above table identity value),ContactType,ContactNumber

How to write two tables insert statements in single stored procedure. The second table "EmpContact" needs the resulted Identity ID from insertion in the first table "Employee"

Answer 1

what you need is SCOPE_IDENTITY() function, it returns last ID within a scope

insert into Employee(FN,LN, Adress)
values(@var1, @var2, @var3)

declare @EmpID int 
set @EmpID = SCOPE_IDENTITY()

insert into EmpContact(Empid, ContactType, contactNumber)
values(@EmpID, @var4, @var5)

Answer 2

ummm... the answer is really simple, just write a procedure with error handling etc.

create procedure dbo.myProc
@param

insert into dbo.Employee(FN,LN,Address)
select @value1, @value2, @value3

insert into dbo.EmpContact(Empid,ContactType,ContactNumber)
select ID,@value4, @value5
from dbo.Employee

go

Answer 3

Assuming your unknown fields are coming in as parameters:

Inside your stored proc...

DECLARE @EmployeeID BIGINT --Or whatever datatype you are using

INSERT INTO Employee
    (FN, LN, Address)
VALUES
    (@FN, @LN, @Address)

SET @EmployeeID = SCOPE_IDENTITY()  --This is probably the line you are looking for

INSERT INTO EmpContact
    (Empid, ContractType, ContractNumber)
VALUES
    (@EmployeeID, @ContractType, @ContractNumber)

Answer 4

create proc yourproc
(
   -- parameter definitions here
)
as
begin
        insert into Employee
        (FN,LN,Address) 
        values 
        (@FN,@LN,@Address)

declare @EmployeeID int 
set @EmployeeID = SCOPE_IDENTITY()

        insert into EmpContact
        (Empid, ContactType, ContactNumber) 
        values 
        (@EmployeeID, @ContactType, @ContactNumber) 
end

SCOPE_IDENTITY and @@IDENTITY return the last identity values that are generated in any table in the current session. However, SCOPE_IDENTITY returns values inserted only within the current scope; @@IDENTITY is not limited to a specific scope.

Answer 5

您可以使用原始插入内容，但您可以使用第一个表中插入的身份 ID SCOPE_IDENTITY() ，它返回为当前会话和当前范围中的任何表生成的最后一个身份值。
