在SQL Server中,我正在创建一个社交网络数据库,并在响应请求时出错

Question

我想创建一个存储过程来响应朋友请求,但这给了我一个语法错误

CREATE PROC RESPOND_REQUEST @id1   INTEGER,
                            @id2   INTEGER,
                            @reply BIT
AS
  BEGIN
      SELECT R
      FROM   Requests R
      WHERE  r.reciever_id = @id1
             AND r.sender_id = @id2

      SET R.reply = @reply
  END 

Answer 1

也许程序应该是:

CREATE PROCEDURE dbo.RESPOND_REQUEST -- always use dbo prefix
  @id1 INT, 
  @id2 INT, 
  @reply BIT
AS
BEGIN
  SET NOCOUNT ON;

  UPDATE dbo.Requests -- always use dbo prefix
    SET reply = @reply
    WHERE reciever_id = @id1 -- fix this typo - i before e, except after c
      AND sender_id = @id2;
END
GO

关于dbo前缀.

此外,您应该重命名参数,而不是通用@id1,@id2为什么不调用它们是什么,@receiver_id并且@sender_id？只是给他们数字似乎不必要地混淆.
