MYSQL Error : There is no 'aversio'#'%' registered
What this error mean
That actually looks like a permissions issue, like you are trying to connect as aversio to a MySQL server instance which is not configured to allow that user from any (%) domain.
The syntax 'aversio'#'%' looks like the format 'username'#'host', and mysql uses % as the catch-all (any) host wildcard.
Make sure that you create the MySQL user named aversio, and give them the correct permissions on your DB.
EDIT:
IIRC, a user of that name may exist, but with a different domain (i.e. the users table is keyed on the combo of user and host. I've seen this kind of thing happen when I move code from a dev server to a staging server and try to connect fro mthe new host, having forgotten to modify the permissions in MySQL.

I was able to implement a connection from R through RMariaDB and DBI to a remote MariaDB-database. However, I am currently encountering a strange change of numbers when querying the database through R. I'll explain the differences:
I inserted one simple entry in my database with the following command:
INSERT INTO respondent ( id, name ) VALUES ( 2388793051, 'testuser' )
When I connect to this database directly on the remote server and execute a statement like this:
SELECT * FROM respondent;
it delivers these value
id: 2388793051, name: testuser
So I should also be able to connect to the database via R and receive the same results. So when I execute the following code in R, I expect to receive this inserted and saved information displayed above:
library(DBI)
library(RMariaDB)
conn <- DBI::dbConnect(drv=RMariaDB::MariaDB(), user="myusername", password="mypassword", host="127.0.0.1", port="1111", dbname="mydbname")
res <- dbGetQuery(conn, "SELECT * FROM respondent")
print(res)
However, the result of this query is the following
id name
-1906174245 testuser
As you can see, the id is now -1906174245 instead of the saved 2388793051 in the database. I don't understand this weird conversion of integers in the id-field. Can someone explain how this problem emerges and how I might solve it?
EDIT: I don't expect this to be a problem, but just to inform you: I am using an SSH tunnel to enable a connection via these specified ports from my local to my remote machine.
SOLUTION: What made the difference was to specify the id of a respondent in the database specification already as BIGINT instead of INT. Thanks to #JonnyCrunch
I am in the process of setting up a wordpress website that connects to a relay chatroom with an integrated login system, I have connected the database which is working fine however its not allowing the authentication for the users to happen.
The query that i am running in the configuration is:
"SELECT `user_email` AS `email` FROM `wp_users` WHERE `user_login` = #a# AND `user_pass` = MD5(#p#)"
What i am wanting to do is basically have the query check that the user_login exists and then authenticates with the password.
The error that i am currently receiving is as follows:
COMMAND: username#host.host used IDENTIFY and failed to identify to nonexistent account username
This is totally puzzling me now
WordPress doesn't use MD5. So your query is wrong. You can't do it with MySQL only. But you can do it with PHP.
Here is one simple way to achieve it:
Step 1:
Grab class-phpass.php file from WordPress installation (wp-includes directory) and paste it to the neighbour to your request sender file. And use this piece of code there:
require_once("class-phpass.php");
$wp_hasher = new PasswordHash(8, true);
$password='open_password_to_check_here';
$hashed_password='hashed_password_from_mysql'; //select user_pass from wp_users where user_login=#a#;
$result=$wp_hasher->CheckPassword($password,$hashed_password));
//if result is true, then auth is OK.
Alternatively (and the best way) you can use WP REST API, which contains auth process.
In SQL Server (i'm using 2008) is it possible to dynamically access server by server name?
My scenario: I have a production server, a development server, and a test server. Their structure is the same. There is a fourth server with some additional data - let's call it a data server.
On the data server there is a procedure. One of it's parameters is a name of the requesting server:
proc sp_myProcedure(#myId int, #serverName nvarchar(100))
The procedure accesses tables from the data server and from the requesting server. At the moment, to query the requesting server I'm using a case expression:
-- code on the data server
select additionalData = case #serverName
-- if the requesting server is production - query production
when 'ProdServer' then (select field1 from [ProdServer].[MyDataBase].[dbo].[MyTable] ...
-- if the requesting server is test - query test
when 'TestServer' then (select field1 from [TestServer].[MyDataBase].[dbo].[MyTable] ...
-- if the requesting server is development - query development
when 'DevServer' then (select field1 from [DevServer].[MyDataBase].[dbo].[MyTable] ...
end
My question is if there is any other way to access the requesting server. I'd like to replace ifs and cases with something more dynamic. Is it, for instance, possible to use the server name variable to dynamically access specific server. Something similar to the following (mocked) query:
declare myServer <server type> = Get_Server(#serverName)
-- the query
additionalData = select field1 from [myServer].[MyDataBase].[dbo].[MyTable]
I liked this approach
SELECT
SERVERPROPERTY('MachineName') AS [ServerName],
SERVERPROPERTY('ServerName') AS [ServerInstanceName],
SERVERPROPERTY('InstanceName') AS [Instance],
SERVERPROPERTY('Edition') AS [Edition],
SERVERPROPERTY('ProductVersion') AS [ProductVersion],
Left(##Version, Charindex('-', ##version) - 2) As VersionName

Another approach which we were using was
Creating one database called database_yourprojectname
So, for the explanation I'm using database name as northwind
after that you can create one new database called northwind_db
Which has a following fields:
Servername,username(encrypted),password(encrypted),active
And then you can either make one page to insert/update/delete current database used there
or you can add statically data to it..so, you can use the database which is active currently.
Or use simple one:
SELECT ##SERVERNAME
Which is already stated here
is there any way to pull the Service_Name from the TNS file using VBA? since anyone can name their TNS entries anything they want - my pass-through queries won't work on their computers.
if there's a way to setup the queries by using TNS entry itself instead of the SERVICE_NAME - that'd work too. i just want to make sure my database is not computer specific in any way.
for example, here's my DSN-less connection string
[ODBC] DRIVER={Oracle in Oracle1}
UID=username
Pwd=password
DBQ=myTNSEntryName.ourcompany.com
Trusted_Connection=Yes
server=
(DESCRIPTION=
(ADDRESS=
(PROTOCOL=TCP)
(HOST=ourhost.ourcompany.com)
(PORT=9999)
)
(CONNECT_DATA=
(SERVICE_NAME=myTNSEntryName.ourcompany.com)
) )
and here's my TNS entry
myTNSEntryName.ourcompany.COM=
(DESCRIPTION=
(ADDRESS=
(PROTOCOL=TCP)
(HOST=ourhost.ourcompany.com)
(PORT=9999)
)
(CONNECT_DATA=
(SERVER=dedicated)
(SERVICE_NAME=ourdatabasename.ourcompany.com)
) )
in the TNS file the SERVICE_NAME is ourdatabasename, but since i named the TNS entry myTNSEntryName - now using report.ourcompany.com as the SERVICE_NAME doesn't work.
thank you
EDIT: to clarify a little, basically i'm looking for a way to set up a DSN'less connection string that i can then use in the ODBC CONNECT STR line in the PROPERTIES of a MS Access Pass-Through query AND in the Docmd.TransferDatabase.
OR, find a way to read the user's TNS Entry name (not the database name, but whatever they choose to name their entires)
The DBQ parameter is the TNS name that you want to use. The Oracle ODBC driver does not use the SERVER or TRUSTED_CONNECTION parameters. Microsoft's ODBC Driver for Oracle uses the SERVER parameter. I'm not sure what, if any, driver might use the trusted_connection parameter or what that might do in an Oracle context. Both of those should be removed.
Of course, the name of the Oracle ODBC driver may well be different on different machines since it contains the name of the Oracle Home and users are free to set that when they install the Oracle client. If you want that to work on arbitrary machines, you'd need to interrogate the ODBC Driver Manager (using the SQLDrivers function) or you'd need to query the registry key HKEY_LOCAL_MACHINE\SOFTWARE\ODBC\ODBCINST.INI\ODBC Drivers
I have a lot of services which query the database. All of them work fine but one service calling a stored procedure gives me following error:
Could not find server 'dbo' in
sys.servers. Verify that the correct
server name was specified. If
necessary, execute the stored
procedure sp_addlinkedserver to add
the server to sys.servers.
I have not idea why all the other stored procedures work fine and this one not...
By the way, I use SubSonic as data access layer.
Please run select name from sys.servers from the server which you mentioned as default server in configuration file.
Here in name column values should match with your server names used in the report query.
e.g serverXXX.databasename.schema.tablename
serverXXX should be there in the result of select name from sys.servers otherwise it gives error as got.
It sounds like there is an extra "." (or two) in the mapping - i.e. it is trying to find server.database.schema.object. Check your mapping for stray dots / dubious entries.
Also make sure that the server name matches what you think it is. If you rename the host that SQL Server is running on, you need to rename the SQL Server, too.

I had another issue with the same exception so I'll post here if someone stumble upon it:
Be careful if you specify the server name in synonyms. I had a different server name on my staging machine and production and it caused the same 'cannot find server'-error.
(Guess you shouldn't use synonyms that much anyway but it's useful in some migration scenarios)
In my case i was facing same issue with following ,
SqlCommand command = new SqlCommand("uspx_GetTemplate", connection);
but after adding square bracket to stored procedure name it get solved.
SqlCommand command = new SqlCommand("[uspx_GetTemplate]", connection);
