我对此有点困难,因为我不确定如何在 SQL Server 中执行此操作。
基本上,我想在数据库中插入一个新行,获取刚刚插入的 PK 值(相同的查询)并将其输出回称为存储过程的任何内容:
CREATE PROCEDURE Users_Insert
-- Add the parameters for the stored procedure here
@userid int output,
@name varchar(50),
@surname varchar(50),
@email varchar(200),
@password varchar(50),
@location varchar(50)
AS
BEGIN
-- SET NOCOUNT ON added to prevent extra result sets from
-- interfering with SELECT statements.
SET NOCOUNT ON;
-- Insert statements for procedure here
insert into Users(FirstName, LastName, Email, Password, Location)
values(@name, @surname, @email, @password, @location);
GO
@userid = @@IDENTITY;
END
我在 MySQL 中这样做如下:
CREATE PROCEDURE Users_Insert(@userid int output, @name varchar(50), @surname varchar(50), @email varchar(200), @password varchar(50), @location varchar(50)
BEGIN
insert into Users(FirstName, LastName, Email, Password, Location)
values(@name, @surname, @email, @password, @location);
set @userid = last_insert_id();
END
SQL Server 给我一个错误:
消息 102,级别 15,状态 1,过程 Users_Insert,第 18 行
“@userid”附近的语法不正确。
坦率地说,我不确定我是否正确声明了输出参数,有人可以提供建议吗?
