SQL 存储过程带参数,请问哪里有问题
CREATE PROCEDURE rs_main_user
@name varchar(30)
with encryption
AS select * from main_users
where username = @name
go
exec rs_main_user

提示我没有声明变量@name,请问大家这个是咋回事,谢谢

[解决办法]
exec rs_main_user 'aaa '
[解决办法]
exec rs_main_user 要加参数值
[解决办法]
就是嘛，没有参数肯定不对，不过在这个过程中应该判断一下是否为空
[解决办法]
或者这样写

ALTER PROCEDURE rs_main_user
@name varchar(30)=NULL
with encryption
AS
if @name is null
select * from main_users
else
select * from main_users
where username = @name
go

exec rs_main_user
