標識列

Question

存儲過程

CREATE PROCEDURE [dbo].[Insert_Customer] 
@id int, 
@FName varchar(50) , 
@MName varchar(50) , 
@LName varchar(50) , 
@Age int , 
@Citizen varchar(50), 
@Gender varchar(50) , 
@DOB varchar(50) , 
@Status varchar(50) , 
@Nationality varchar(50) , 

@Country varchar(50) , 
@State varchar(50) , 
@City varchar(50) , 
@Address varchar(MAX) , 
@Pin varchar(50) , 
@AccNo int IDENTITY (100,1), 
@Branch varchar(50) , 

@IDProof varchar(50) , 
@IDNo varchar(50) , 
@IDName varchar(50) , 
@DOI varchar(50) , 
@Date datetime 
AS 
BEGIN 

Insert into tbl_Customer1 
values(@id,@FName,@MName,@LName,@Age,@Citizen,@Gender,@DOB,@Status,@Nationality) 

Insert into tbl_Customer2 
values(@id,@Country,@State,@City,@Address,@Pin,@accno ,@Branch) 

Insert into tbl_Customer3 
values(@id,@IDProof,@IDNo,@IDName,@DOI,@Date) 

END 

在這裏的錯誤是

Msg 156, Level 15, State 1, Procedure Insert_Customer, Line 28
Incorrect syntax near the keyword 'IDENTITY'.
Msg 137, Level 15, State 2, Procedure Insert_Customer, Line 42
Must declare the scalar variable "@accno".
Msg 137, Level 15, State 2, Procedure Insert_Customer, Line 44
Must declare the scalar variable "@IDProof".

Answer 1

你不能聲明INT IDENTITY變量/參數。如果將特定列定義爲IDENTITY列，則不必添加它的值插入語句。如果您不指定列值，則會自動設置身份號碼。

Answer 2

@AccNo int IDENTITY (100,1), 

你不能設置一個參數作爲身份。 爲什麼你首先需要它？

這應該只在你的桌子上。

你能解釋爲什麼你需要它，所以我們可以幫你嗎？
