@Sami hash functions are hard to reverse. By design.
There is a way, it just takes awful lot of time ;)
 
Sami
Sami
Ok, but if the hashed string was a user password
how to compare it
when the user try to login?
 
ypercubeᵀᴹ
ypercubeᵀᴹ
That's why they are used to "save" passwords. Only the hashed value is saved.
When a user tries to to login the hashed value of his provided password is compared against the stored value of the hashed (real) password.
 
Sami
Sami
ok, let me try it
 
ypercubeᵀᴹ
ypercubeᵀᴹ
If they match we assume that he knows the password.
or he is very, very lucky

It works
In that way, when the user forget his password
 
ypercubeᵀᴹ
ypercubeᵀᴹ
he loses access
 
Sami
Sami
the only way to login is: reset password
 
ypercubeᵀᴹ
ypercubeᵀᴹ
yes

Ok
As I know
in most databases (or better to say sites)
there is no delete in the db (I mean a real delete)
This case I see it i two places (popular sites)
1st one is Facebook
2nd one is SO
How can I prove it? ok
Conversasions in the facebook
when you click a delete button to delete a message that you send it to another one
it will show you that the message was deleted
but in real, it's not deleted, cause when go to the reciver and open the conversation you will fid it there
that fb it's the Information Cemetery
How can they do that, I don't know.
Same as SO when you delete a question/answer
you can undelete it, so the Q/A is not deleted yet
EXCEPT
the comments when you delete them you can't undelete it
My question: How they do that? create a table to hold deleted A/Q for a while?
@JoeObbish I see a post about helping users to post a good questions on Meta
tbh, it's a great idea
but this idea can only reduce the bad questions, cause not all users will follow the instructions

Someone was pissed with Verace, yesterday: dba.stackexchange.com/users/34007/…
 
Sami
Sami
@ypercubeᵀᴹ Same as me
Serial downvotes
Paul will deal with the guy who did that

@Sami but you have no answers!
Oh, you probably mean SO ...
 
Sami
Sami
Yeah, on SO I don't know why those days every post it will get a DV
I will have posts on dba soon, when I feel that I can post here
(We always learn)
 
ypercubeᵀᴹ
ypercubeᵀᴹ
@Sami probably because you check with MOD while the question asks for checking of Doc_Type (if it's AA or BB)
 
Sami
Sami
11:47 AM
Well, it's a solution, when you look to the sample data
also there is post based on AA & BB
so I try to give him another way
 
ypercubeᵀᴹ
ypercubeᵀᴹ
Yes, but we don't know if all their data alternate between AA and BB
When you make assumptions, you should add them in your answer.
I suggest you delete the answer. There seem to be at least 3 others that use AA and BB correctly.
I can give you a downvote so you get the Peer Pressure badge ;)

Hi
I would like to ask a question for a substitution variable that display the timetabled sections for a given Month which the user enter at the run time! something like
to_char(S.START_DATE_TIME, 'Month')= '&Month'
the current snippet returns months if I replace the format Month to Mon but it won't return anything if I type the Month during the run time!!

@TomV ha, yes. But I didn't downvote him. Not once, let alone 5 times.
