SQL Server – Sql does not exist, returns 0 rows and should return one

After a while, I really do not know what's wrong here. (SQL is not my cup of tea I would say, but you still have to understand that hehe)

I have 2 tables, in different diagrams, that I need to pass the information from the "master" to "slaves" if the "slaves" do not have this line, c & # 39; is why I try to use it does not exist.

Here is the query that I use:

--Select everything from the master
to select
*
of
(to select
*
of 
         [serversqlexpress].xptoMaster.dbo.CcArtigos
or
Tipo_Doc in (& # 39; INE & # 39 ;, & # 39; INS & # 39;)
and Armazem = 2
and data_mov> = & # 39; 01-07-2018 & # 39;) as tmaster
where does not exist
- What does not exist in the slave
(select *
of 
           [serversqlexpress].xptoSlave.dbo.CcArtigos as tslave
or
tmaster.cod_art = tslave.cod_art
and Tipo_Doc in (& # 39; INE & # 39 ;, & # 39; INS & # 39;)
and Armazem = 2
and data_mov> = & # 39; 01-07-2018 & # 39;)

So from what I understood from what I found online (https://www.tutorialgateway.org/sql-not-exists-operator/), I try to select all the elements of the xptoMaster that do not exist on the xptoSlave BUT it returns 0 lines and according to the site, does not see what is the problem with the query, the logic of the site:

TO SELECT [Column Names]
OF [Source]
WHERE NOT EXISTS (Write a subquery to check)

The master test bases have 91 lines and the slave has 90. So I should get the master line that the slave has not, but I get 0 line: /

Edit:

select *
of [serversqlexpress].xptoMaster.dbo.CcArtigos
where does not exist
(select * from [serversqlexpress].xptoSlave.dbo.CcArtigos as tslave)

SQL Server – The publication & # 39; My_publication & # 39; does not exist?

We try to test the success of transactional replication.
by googling, I found that I have to run in our editor this stored procedure:

sp_publication_validation

However, when I run:

exec sys.sp_publication_validation
@ publication = ReplicationFaouzi,
@ rowcount_only = 0,
@ full_or_fast = 0,
@ shutdown_agent = 0

I receive this error:

Msg 20026, Level 16, State 1, Procedure sp_MSpublication_validation Line 57
The publication & ReplicationFaouzi & # 39; does not exist?

When I run this sql:

SELECT publication
MSpublications
ORDER BY publication 

I get as a result:

RéplicationFaouzi

web server – When should you give up trying an xss on a part of a website?

I wonder when do you give up a type of user input to exploit? What are the things that go through your mind and tick, that make you think that the entry is properly cleaned?

I have just begun. What I'm looking for when I test an XSS and determine it correctly is when they encode an entry like (! @ # $% ^ & * "& # 39; ((>>))" With entities HTML, that's all.

security – How to secure my queried data from my local MySQL server on a remote machine with a shared root with an untrusted entity?

I have a remote client computer placed in a server center belonging to an entity that must also own the root of the client computer in accordance with industry regulations. The client machine runs a C ++ program that uses libmysqlclient.so and periodically polls a MySQL server in my office via the Internet.

Because the data is extremely sensitive, I need to protect this data from disclosure during the data transfer process. Nobody is trusted in the host, including its owner who owns the root of the client machine.

At first, the JSON The format of the C ++ program configuration database contains an explicit IP address, port, user, and password. Anyone with the root can read them and use them to connect to our server from the client machine. As the IP address and the port must be disclosed to the host owner who manages the intranet, gateway and firewall in accordance with the regulations, I replace the user and the password by encrypted strings in the configuration and the C ++ program will decrypt them at startup to get the desired result. real user and password to connect to the server.

However, the root user can replace libmysqlclient.so in the system with a modified version so that the user and the password are printed when establishing a connection. Then I change the C ++ program to static link to libmysqlclient.a at the time of compilation.

However, the transferred data is still in the clear. I'm therefore activating SSL on the MySQL server and modifying the user as REQUIRE SSL. So, the attack by the middle man is not supposed to be easy.

For SSL to work, I also need to put ca, client-cert, and client-key files on the client machine. I am wondering if the host owner can capture the encrypted traffic transferred and use these files to decrypt the data without knowing the user name and password of the database.

In addition, is there an obvious vulnerability on the client side after all these configurations? Suppose the network structure and the use of MySQL are not changed.

design – Best approach for the transformation project: database server processing vs application server processing

We are working on a transformation project

It has records in the entityA table and entityB, which has an entityAB relationship.
We need to delete the records from the entityA table and recreate them with other parameters, say that the new records are rowA & # 39 ;. Now, based on the matching entries between row A and row A, we need to update the recordings of the AB relation with the relation A & B, this is where row A was now row A & # 39;

To do this, there are two approaches:

  1. Perform full backup processing, update the relationship with SQL
    procedures (pl / sql).
  2. Transform records into application
    server and persist them in the database.

We have oracle server 12c, java8, hibernation, spring start as technology stack.

Which approach is the best?

constraints

  1. large number of recordings to process.
  2. many relationships such as relationAC, relationAD which must also be updated.
  3. The transformation can last a long time. For example, backing up and deleting stocks can take a week or more, due to business constraints.
