The SingleStore ODBC Driver is a powerful tool that allows you to connect with live data from SingleStore, directly from any applications that support ODBC connectivity.

Access SingleStore data like you would a database - read, write, and update SingleStore. through a standard ODBC Driver interface.

Replicate SingleStore Data from PowerShell

Write a quick PowerShell script to query SingleStore data. Use connectivity to the live data to replicate SingleStore data to SQL Server.

The CData ODBC Driver for SingleStore enables out-of-the-box integration with Microsoft's built-in support for ODBC. The ODBC driver instantly integrates connectivity to the real SingleStore data with PowerShell.

You can use the .NET Framework Provider for ODBC built into PowerShell to quickly automate integration tasks like replicating SingleStore data to other databases. This article shows how to replicate SingleStore 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 SingleStore

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.

The following connection properties are required in order to connect to data.

Server: The host name or IP of the server hosting the SingleStore database.
Port: The port of the server hosting the SingleStore database.
Database (Optional): The default database to connect to when connecting to the SingleStore Server. If this is not set, tables from all databases will be returned.

Connect Using Standard Authentication

To authenticate using standard authentication, set the following:

User: The user which will be used to authenticate with the SingleStore server.
Password: The password which will be used to authenticate with the SingleStore server.

Connect Using Integrated Security

As an alternative to providing the standard username and password, you can set IntegratedSecurity to True to authenticate trusted users to the server via Windows Authentication.

Connect Using SSL Authentication

You can leverage SSL authentication to connect to SingleStore data via a secure session. Configure the following connection properties to connect to data:

SSLClientCert: Set this to the name of the certificate store for the client certificate. Used in the case of 2-way SSL, where truststore and keystore are kept on both the client and server machines.
SSLClientCertPassword: If a client certificate store is password-protected, set this value to the store's password.
SSLClientCertSubject: The subject of the TLS/SSL client certificate. Used to locate the certificate in the store.
SSLClientCertType: The certificate type of the client store.
SSLServerCert: The certificate to be accepted from the server.

Connect Using SSH Authentication

Using SSH, you can securely login to a remote machine. To access SingleStore data via SSH, configure the following connection properties:

SSHClientCert: Set this to the name of the certificate store for the client certificate.
SSHClientCertPassword: If a client certificate store is password-protected, set this value to the store's password.
SSHClientCertSubject: The subject of the TLS/SSL client certificate. Used to locate the certificate in the store.
SSHClientCertType: The certificate type of the client store.
SSHPassword: The password that you use to authenticate with the SSH server.
SSHPort: The port used for SSH operations.
SSHServer: The SSH authentication server you are trying to authenticate against.
SSHServerFingerPrint: The SSH Server fingerprint used for verification of the host you are connecting to.
SSHUser: Set this to the username that you use to authenticate with the SSH server.

Connect to SingleStore

The code below shows how to use the DSN to initialize the connection to SingleStore data in PowerShell:


$conn = New-Object System.Data.Odbc.OdbcConnection
$conn.ConnectionString = "DSN=CData SingleStore Source x64"

Back Up SingleStore 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 SingleStore 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 SingleStore through the .NET Framework Provider for ODBC:

Retrieve SingleStore Data


$sql="SELECT ShipName, ShipCity 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 SingleStore Data


$cmd = New-Object System.Data.Odbc.OdbcCommand("UPDATE Orders SET ShipCountry='USA' WHERE Id = @myId", $conn)
$cmd.Parameters.Add(new System.Data.Odbc.OdbcParameter("myId","001d000000YBRseAAH")
$cmd.ExecuteNonQuery()

Insert SingleStore Data


$cmd = New-Object System.Data.Odbc.OdbcCommand("INSERT INTO Orders SET ShipCountry='USA' WHERE Id = @myId", $conn)
$cmd.Parameters.Add(new System.Data.Odbc.OdbcParameter("myId","001d000000YBRseAAH")
$cmd.ExecuteNonQuery()

Delete SingleStore 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()
