We are working on a GSA project. We are using GSA version 7.2 and Connector database adapter 3.2.4. The problem we are facing is that:
- We are crawling data from a MSSQL database 2008 R2. Instance of database is not the default. That is not the instance 'SQLEXPRESS'. And GSA do not connect to the database.
Have you added JDBC connection URL: DB_HOST_NAME_OR_IP:1433;databaseName=Database Instance Name

In Visual Studio 2019 menu: Tools -> Connect To Database I see "MySQL Database" data provider, but an attempt to connect to my aurora database finishes with weird error:
"Microsoft Visual Studio / Unable to connect to any of the specified MySQL hosts. Sequence contains more than one matching element"
I have Aurora DB based on MySQL 5.6.10. I can connect to it using the latest MySQL Workbench 8.0.18. I have the latest "MySQL for Visual Studio 1.2.9" and Connector/NET 8.0.18. I work with .NET Framework 4.7.2. I can also connect to other (normal) MySQL instances from the Visual Studio, but not to Aurora DB.
My final target is to create ADO.NET Entity Data Model from the amazon db, but this fails on the same error message.
Is there any guide how to connect MySQL Aurora DB with .NET Framework (not .NET Core)? A guide to extremely simple application which can download single value from any table would mean a significant step forward for me.
OK. I found it's a Bug #97448 introduced in MySql.Data 8.0.18. Workaround is to define server name by IP address instead of xxx.rds.amazonaws.com address.
It's a know bug.
FYI the previous version of mysql.data (v6.10.9) is also affected.
As a workaround you could resolve the DNS value to an IP address manually.
In the code example below I check if the server value is an IP then I resolve the DNS name when the value is not an IP address.
if (IPAddress.TryParse(server, out var ipAddress))
{
// The server value is an IP address, it can be used directly
}
else
{
server = Dns.GetHostEntry(server).AddressList.FirstOrDefault()?.MapToIPv4().ToString();
}
return new MySqlConnectionStringBuilder
{
Server = server
// ...
};
How do I connect MySQL database to a VB.NET 2015 application?
In order to connect to MySQL Database, you need to ensure below things:-
MySQL Connector is installed
https://dev.mysql.com/downloads/connector/net/
Define connection string as Server=myServerAddress;Database=myDataBase;Uid=myUsername;Pwd=myPassword;
Or consult following link to suit your situation http://www.connectionstrings.com/mysql-connector-net-mysqlconnection/
Rest is same as you work MSSQL or OleDB connections.
I want to use exist db on mysql from mvc asp.net.
I installed mysql plugin for vs and mysql connector net.
Add connection string to config.
When I start vs in server explorer I see working connection, but when in project I try to add new ado.net entity data model -> generate from database wizard don't know about mysql in general, there are defaultconnection to MS sql and only two varients for new connection:
Microsoft SQL Server
Microsoft SQL Server Database file
Other
Maybe I forgot something install?
Thanks for help.
I want to add a MySQL instances that is running as a RDS service through Amazon Web Services as a Linked Server in Microsoft SQL Server Management Studio.
Does anyone know of any information on how I can set this up?
What I want to be able to do is query data from my MySQL server from the local Micorsoft SQL server and then combine the data into other queries.
SELECT *
FROM OPENQUERY(MySQL_Link, 'SELECT *
FROM users
WHERE name = 'test')
Do you already have the ODBC connection set up to connect to the instance?
Unable to connect to remote mysql server using unixodbc, libmyodbc
I would think that once you have that working, you would be able to use the same process for creating a linked server to MySQL
I hope this is helpful.
I have set up ADF essentials library on my glassfish server as specified here . I am able to successfully deploy applications to the glassfish server from jDeveloper and the application runs fine until there is a database operation involved and it is when it throws up the following error
No object bound to name java:comp/env/jdbc/myDataSource
The application works fine on IntegratedWeblogicServer, so am guessing I have not set up the mysql datasource in my glassfish properly. I have setup connection as shown here and the connection name is "myDataSource" (which is same as provided in the jDeveloper's DB connection name).
Help!!!
You need to set the name of the datasource in your Application Module configuration tab to match the name of the datasource you defined in your GlassFish instance.
