sql server 2005 - Stored Procedure in SQLServer user login -


I write the process for logging where users can send usernames or e-mails for login and password. My process is like this: Process users_login (@ Username varchar (50), @ password varchar (50), @ melith varchar (50), @ ret int output) password, e- Mail, where user name = isnull (@username, blank) or emailid = isnull (@mailid, null) and [password] = @password (@@ rowcount> 0) set @rate = 1 end set and otherwise Start Set @ rate = 0 End End

Is it OK or Amendment

There is a problem in the query itself, you have to bracket The statement must be placed around the or statement otherwise the statement will always return a line when the user name will have a match in the table: / pre>

Others should not save passwords in clear text Please read something like this

For the style, I personally They would not like this. As others have pointed out that isnull () in this case, it is similar to not using it. You can also reduce the use of @@ puncto ount by setting @ret to the selected statement. If it does not give a line then it will not be set so that it can achieve the same end.

Then I will write it:

process user_login (@ username varchar (50), @pavard wart (50), @ melith varchar (50), @inte art output ) Set @ rate = 0 as the @ rate = 1 users from where the user endorses (Username = isnull (user name, zero) or email = isnull (@ email, tap) and [password] = @ password

sql - dynamically varied number of conditions in the 'where' statement using LINQ -

I am using my first project LINQ (in mvc), so maybe there's something very simple that I remember. However, a day of searching and experimenting does not work, so it works. I am trying to write a LINQ query (Linux to SQL) in which in many cases where the statement is different from an OR or an AND. We do not know how many conditions are going in the query till runtime. This search is for filter control, where the user can choose multiple criteria for filtering. Select from table where table.col = 1 or table.col = 2 or table.col = 7 .... 'Other number of conditions Before I just create the SQL query as a string, while looping over all the situations. However, it seems that there should be a good way to do this in LINQ. I tried to use Expression trees, but they had a second thought for this moment on my head, where the lambda function was to be executed inside the statement such as: values ​​for matchingRows = matchingRows for each value Where (function (row) row.c...

asp.net mvc - Dynamically Generated Ajax.BeginForm -

I have a problem with ASP.NET MVC Ajax forms. I generate many Ajax form in a table such as: & Lt; Input type = "submit" name = "activity" value = "add activity" / & gt; & Lt;%}% & gt; & Lt; / TD & gt; & Lt; / TR & gt; & Lt;%}% & gt; So far so good. When I post one of those forms, it gives a partial view in a div, and in this new partial view a new Ajax Beginnform (which is not in Genesis form) This second Ajax Beginnorf is exactly like the ones I got on the table, but when I post it, I do not get the "Ajax Post", but a normal post that sends me to a new page, I do not know whether the two Ajax forms What is the reason for the difference between, why is it the "dynamically generated" Ajax form behaves like a normal HTML form? By the way, I know that I can do it in different ways using javascript, but I would like to understand whether it can only be done using MVC helplars and Ajax lib...
