Write a quick PowerShell script to query DB2 data. Use connectivity to the live data to replicate DB2 data to SQL Server.
The CData ODBC Driver for DB2 enables out-of-the-box integration with Microsoft's built-in support for ODBC. The ODBC driver instantly integrates connectivity to the real DB2 data with PowerShell.
You can use the .NET Framework Provider for ODBC built into PowerShell to quickly automate integration tasks like replicating DB2 data to other databases. This article shows how to replicate DB2 data to SQL Server in 5 lines of code.
You can also write PowerShell code to execute create, read, update, and delete (CRUD) operations. See the examples below.
Create an ODBC Data Source for DB2
If you have not already, first specify connection properties in an ODBC DSN (data source name). This is the last step of the driver installation. You can use the Microsoft ODBC Data Source Administrator to create and configure ODBC DSNs.
Set the following properties to connect to DB2:
- Server: Set this to the name of the server running DB2.
- Port: Set this to the port the DB2 server is listening on.
- Database: Set this to the name of the DB2 database.
- User: Set this to the username of a user allowed to access the database.
- Password: Set this to the password of a user allowed to access the database.
You will also need to install the corresponding DB2 driver:
- Windows: Install the IBM Data Server Provider for .NET.
On Windows, installing the IBM Data Server Provider is sufficient, as the installation registers it in the machine.config.
- Java: Install the IBM Data Server Driver for JDBC.
In the Java version, place the IBM Data Server Driver JAR in the www\WEB-INF\lib\ folder for this application.
Connect to DB2
The code below shows how to use the DSN to initialize the connection to DB2 data in PowerShell:
$conn = New-Object System.Data.Odbc.OdbcConnection
$conn.ConnectionString = "DSN=CData DB2 Source x64"
Back Up DB2 Data to SQL Server
After you enable caching, you can use the code below to replicate data to SQL Server.
Set the following connection properties to configure the caching database:
CacheProvider: The name of the ADO.NET provider. This can be found in the Machine.config for your version of .NET. For example, to configure SQL Server, enter System.Data.SqlClient.
CacheConnection: The connection string of properties required to connect to the database. Below is an example for SQL Server:
Server=localhost;Database=RSB;User Id=sqltest;Password=sqltest;
The SQL query in the example can be used to refresh the entire cached table, including its schema. Any already existing cache is deleted.
$conn.Open()
# Create and execute the SQL Query
$SQL = "CACHE DROP EXISTING SELECT * FROM " + $Orders
$cmd = New-Object System.Data.Odbc.OdbcCommand($sql,$conn)
$count = $cmd.ExecuteNonQuery()
$conn.Close()
The driver gives you complete control over the caching functionality. See the help documentation for more caching commands and usage examples. See the help documentation for steps to replicate to other databases.
Other Operations
To retrieve DB2 data in PowerShell, call the Fill method of the OdbcDataAdapter method. To execute data manipulation commands, initialize the OdbcCommand object and then call ExecuteNonQuery. Below are some more examples CRUD commands to DB2 through the .NET Framework Provider for ODBC:
Retrieve DB2 Data
$sql="SELECT OrderName, Freight from Orders"
$da= New-Object System.Data.Odbc.OdbcDataAdapter($sql, $conn)
$dt= New-Object System.Data.DataTable
$da.Fill($dt)
$dt.Rows | foreach {
$dt.Columns | foreach ($col in dt{
Write-Host $1[$_]
}
}
Update DB2 Data
$cmd = New-Object System.Data.Odbc.OdbcCommand("UPDATE Orders SET ShipCity='New York' WHERE Id = @myId", $conn)
$cmd.Parameters.Add(new System.Data.Odbc.OdbcParameter("myId","001d000000YBRseAAH")
$cmd.ExecuteNonQuery()
Insert DB2 Data
$cmd = New-Object System.Data.Odbc.OdbcCommand("INSERT INTO Orders SET ShipCity='New York' WHERE Id = @myId", $conn)
$cmd.Parameters.Add(new System.Data.Odbc.OdbcParameter("myId","001d000000YBRseAAH")
$cmd.ExecuteNonQuery()
Delete DB2 Data
$cmd = New-Object System.Data.Odbc.OdbcCommand("DELETE FROM Orders WHERE Id = @myid", $conn)
$cmd.Parameters.Add(new System.Data.Odbc.OdbcParameter("myId","001d000000YBRseAAH")
$cmd.ExecuteNonQuery()
