MarkLogic Icon MarkLogic ODBC Driver

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

Access MarkLogic like you would a standard RDBMS database - read, write, and update through an ODBC Driver.

Replicate MarkLogic Data from PowerShell


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



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

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

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 User, Password, and Server to the credentials for the MarkLogic account and the address of the server you want to connect to. You should also specify the REST API Port if you want to use a specific instance of a REST Server.

Connect to MarkLogic

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

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

Back Up MarkLogic 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 " + $Customer $cmd = New-Object System.Data.Odbc.OdbcCommand($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 MarkLogic 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 MarkLogic through the .NET Framework Provider for ODBC:

Retrieve MarkLogic Data

$sql="SELECT Name, TotalDue from Customer" $da= New-Object System.Data.Odbc.OdbcDataAdapter($sql, $conn) $dt= New-Object System.Data.DataTable $da.Fill($dt) $dt.Rows | foreach { $dt.Columns | foreach ($col in dt{ Write-Host $1[$_] } }

Update MarkLogic Data

$cmd = New-Object System.Data.Odbc.OdbcCommand("UPDATE Customer SET Id='1' WHERE Id = @myId", $conn) $cmd.Parameters.Add(new System.Data.Odbc.OdbcParameter("myId","001d000000YBRseAAH") $cmd.ExecuteNonQuery()

Insert MarkLogic Data

$cmd = New-Object System.Data.Odbc.OdbcCommand("INSERT INTO Customer SET Id='1' WHERE Id = @myId", $conn) $cmd.Parameters.Add(new System.Data.Odbc.OdbcParameter("myId","001d000000YBRseAAH") $cmd.ExecuteNonQuery()

Delete MarkLogic Data

$cmd = New-Object System.Data.Odbc.OdbcCommand("DELETE FROM Customer WHERE Id = @myid", $conn) $cmd.Parameters.Add(new System.Data.Odbc.OdbcParameter("myId","001d000000YBRseAAH") $cmd.ExecuteNonQuery()
