Please tell me how to connect to mysql database server from another mysql database server running in two different locations and access all the tables and update them ?
afaik there is no direct "database link" in mysql like there is in oracle. what you can do is master-master replication of two databases and then update locally. similar question with more info:
Oracle Database Link - MySQL Equivalent?
You could pop a MySQL Proxy client between the two servers and send your queries to it and let it do all the talking backwards and forwards between the other boxes.

Good morning!
I have 2 tables that are stored on different databases - different mySQL hostnames.
How to I join them?
Is there a way to open a connection to a database, being connected to another, using commands at the MYSQL Workbench GUI interface (not command prompt) and then query it?
Many thanks,
I am new to databases, have done my basic "homework" regarding the theoretical part, and set about using MySQL Server through MySQL Workbench.
I have created four "connections" which appear on the Workbench homescreen dashboard, and I have also created some tables. But when I login through any connection (using user name and password), I can see all of the tables that I have created. So can anyone please tell me what is the point behind multiple connections then? What exactly is a "Connection" in MySQL Workbench?
I tried googling it, searched it on StackOverflow, and even referred the user manual of MySQL workbench, but got no answers.
Each MySQL connection contains its own set of definitions. For example, the connections might connect to different MySQL servers, or the same MySQL server with different usernames, or enable SSL for one, or you might set up a connection to a remote MySQL server using the SSH options, and so on.
As for multiple connections to the same local MySQL server, you might have one connection using "root" with another using a less privileged user. Depending on how you set up the users, they may (or may not) both have rights to see and use the same databases (information).
So to summarize, connections simply connect to the MySQL server. If two connections use the same exact information then the results will be identical. However, that is not a common use case.
I am working with MySQL Workbench and I want to query 2 servers at the same time. I searched and find out that the best way to proceed is to create a linked server.
I am wondering is it possible to create this only using workbench or MySQL server in general ?
There's nothing in MySQL Workbench that lets you send a query to more than one server at a time.
i have 3 servers for three applications on aws ec2 using MySql database,
now each of the application is having amember that is client subscription app,
it connects with sql databse that is created in each instance
so in this way every amamber app is having diffrent database in each server,
now we are working with a device ROKU we need to pass the XML attributes from amember to it
to varify the user so he can watch online streaming tv.
the objective
now i need to make one database that will be connected with each server using amember
so each server access one database .
Options
my options are aws RDS ,dynamoDb
Now can anyone put me in the right direction, for that.
in simple Words
need to connect my multiple apps (same app) with one database
HELLLLP
If you need to connect to a mysql database, DynamoDB is not the answer. It isn't a mysql database.
RDS is a mysql database. It connects like any other mysql database. You haven't mentioned what language[s] you are using, however. Googling "connect to mysql with [language]" should help.
I think it would be best to stick with relational databases such as MySQL.
Amazon RDS is a managed MySQL solution, but you don't have to use it for your needs.
You can use one of your EC2 instances or a new EC2 instance as the central DB and connect all the other servers to it for quires. There are pros and cons for choosing RDS over your own SQL server. If you have any questions there, feel free to edit your question and add them.
EDIT according to comment
In order to connect your application with the local MySQL. Your are probably using a connection string that points to either "localhost" or "127.0.0.1"... That is the IP of your local machine. You will have to change it to the remote IP of the machine where the DB is stored remotely.
I use Mysql query browser on my pc for data entry,appreciate that let me how can i update my table on server after enter new records in Mysql query browser? is there any way that we sync to table(on server and on client )and sending new records to server?
thanks
If you want to keep your local and remote MySQL databases in sync, the obvious solution would be to use the replication features built into MySQL.
It sounds as if you have 2 data stores - one local, and one remote. Your question doesn't explicitly state that you actually have 2 separate databases, only that you're using MySQL Query Browser. You mention the MySQL Query Browser is on your PC, but it's not clear which database(s) it's connecting to. Is it a local database? Remember: the MySQL Query Browser is just an application that connects to a MySQL database.
It sounds as if you're looking for replication between MySQL servers. You mention 'sending new records' to the 2nd server. Are you looking for delete & update operations to be synchronized as well? A bit more information/requirements are needed before deciding on a solution.
The MySQL docs on Replication will get you started on replication, if that's the solution you need. This assumes your database hosts are in a master-slave relationship. That is, there is one good copy of data, and the other is to be a mirror for the master.
