Hey @Björn Holmgren
,
To connect to IBM Db2 from a .NET 6 application, you can use the IBM.Data.DB2.Core NuGet package. Here's a step-by-step guide to help you establish a connection:
Step 1: Install the IBM.Data.DB2.Core NuGet package In your .NET 6 project, open the NuGet Package Manager and search for "IBM.Data.DB2.Core". Install the package into your project.
Step 2: Import the necessary namespaces At the top of your code file, import the following namespaces:
using IBM.Data.DB2.Core;
using IBM.Data.DB2.Core.Types;
Step 3: Establish a Db2 connection To connect to the Db2 database, create a new instance of the DB2Connection
class and set the connection string with the appropriate credentials and database details:
string connectionString = "Server=<db2_server_address>;Database=<database_name>;UID=<username>;PWD=<password>;";
using (DB2Connection connection = new DB2Connection(connectionString))
{
connection.Open();
connection.Close();
}
Replace <db2_server_address>
, <database_name>
, <username>
, and <password>
with the actual values for your Db2 server.
Step 4: Execute queries or commands Once the connection is established, you can execute SQL queries or commands using the DB2Command
class:
using (DB2Command command = connection.CreateCommand())
{
command.CommandText = "SELECT * FROM your_table_name";
using (DB2DataReader reader = command.ExecuteReader())
{
while (reader.Read())
{
}
}
}
Adjust the SQL query and table name as per your requirements. Use the appropriate DB2DataReader
methods to access the data based on the expected data types.
Remember to handle any exceptions that may occur during the connection or database operations using try-catch blocks.
This guide provides a basic outline of connecting to Db2 from a .NET 6 application. You may need to refer to the IBM.Data.DB2.Core documentation for more advanced usage scenarios or specific configuration options.
I hope this gives you a complete insight on how to handle it !

Subject: Create Database
We have a customer with a Db2 based business system. and we want to develop a .NET 6 application for them, and connect to the Db2 database. I have never worked with IBM Db2 before, and feel I need some help. I installed the IBM NuGet Db2.core, for .NET 6 but it throws errors when I try connect, it throws on the Open command even. So...
Question: How do I connect to Db2 from .NET6?
