Question

create procedure sp_login
as
insert into tbluserlog (_action,date_added,userId) values 
            ('login',getdate(),(select tbluser.userid from tbluser inner join tbluserlog 
    on tbluser.userid=tbluserlog.userid))

这可能吗？如果没有请建议

Answer 1

可以选择INSERT语句的查询部分。你可以像这样使用它。

INSERT into tbluserlog (_action,date_added,userId) 
SELECT 
    'login'
    ,getdate()
    ,tbluser.userid 
FROM tbluser 
INNER JOIN tbluserlog on tbluser.userid=tbluserlog.userid

Answer 2

或者您可以将UserID分配给变量，如下所示 -

CREATE PROCEDURE sp_login
AS

BEGIN

DECLARE @UserID INT = (SELECT tbluser.userid 
                         FROM tbluser 
                         JOIN tbluserlog 
                           ON tbluser.userid = tbluserlog.userid)

INSERT tbluserlog (_action,date_added,userId) 
VALUES ('login', GETDATE(), @UserID)

END

Answer 3

是的，但语法不是“值”，而是

insert into tbluserlog(action, date_added, userId)
select 'login',
    getdate(),
    tbluser.userid
from tbluser 
inner join tbluserlog on tbluser.userid = tbluserlog.userid

...但我真的不认为这是你想要的。这将为每个现有的tbluserlog行插入一个新的tbluserlog行。

我猜你想把userid作为参数传递，即

create procedure sp_login 
    @userid int 
as
insert into tbluserlog(action, date_added, userId)
select 'login', 
       getdate(),
       @userid

Answer 4

我不会在sp_前加上它们为内置程序保留它们的最佳做法，如果删除login，最好不要使用sp_之类的保留字。你可以这样做：

CREATE PROCEDURE [login]
AS
     INSERT INTO tbluserlog
     (
         _action,
         date_added,
         userId
     )
      SELECT
     'login',
      GETDATE(),
      tbluser.userid
      FROM tbluser
      INNER JOIN tbluserlog ON tbluser.userid = tbluserlog.userid

是否可以在insert into语句的值中包含select语句？
