如何检查数据是否被插入或不在存储过程中

Question

我已经创建了一个存储过程来插入员工details.if这个查询是在窗体中执行它不会返回任何值。

create PROCEDURE [dbo].[employee_mst_insertvalues] 
@e_firstname varchar(100), 
@e_middlename varchar(100), 
@e_lastname varchar(100), 
@e_address varchar(1000), 
@e_phoneno varchar(15), 
@mobileno varchar(15), 
@UploadPhoto image 

AS 
declare @employee_id int 
BEGIN 
    SET @employee_id=(select max(Employee_id) from mstEmployee) 
    if @employee_id is null 
    BEGIN 
     set @employee_id=1 
END 
    else 
BEGIN 
     set @employee_id=@employee_id+1 
END 
insert into mstEmployee (Employee_id,E_FirstName,E_MiddleName,E_LastName,E_Address,E_PhoneNo,E_MobileNo,UploadPhoto) 
values(@employee_id,@e_firstname,@e_middlename,@e_lastname,@e_address,@e_phoneno,@mobileno,@UploadPhoto) 
END 

如何返回一个整数值来检查数据是否被插入。

Answer 1

SELECT @@ROWCOUNT会给你受插入语句影响的行数。
