Connect to MarkLogic Data from PowerBuilder
This article demonstrates how to use the CData ODBC Driver for MarkLogic to connect to MarkLogic data and execute queries in PowerBuilder.
The CData ODBC Driver for MarkLogic can be used from any platform or development technology that supports ODBC, including PowerBuilder. This article shows how to connect to MarkLogic data and execute queries from the Database Painter and controls such as the DataWindow.
Connect to MarkLogic as an ODBC Data Source
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.
Create a Profile for the ODBC Driver for MarkLogic
Follow the steps below to use the Database Painter tool to create a database profile based on an ODBC DSN (data source name) for MarkLogic. In the Database Painter, you can use wizards and the UI to work with MarkLogic data.
- In PowerBuilder, click Tools -> Database Painter.
- In the Objects window in the Database Painter, right-click the ODBC node and click New Profile.
- On the Connection tab, enter a name for the profile and select the MarkLogic DSN in the Data Source menu.
![]( "The ODBC DSN, required to create the Database Profile. (Salesforce is shown.)")
- To view and modify a table, right-click a table and then click Edit Data -> Grid.
Using MarkLogic Data with PowerBuilder Controls
You can use standard PowerBuilder objects to connect to ODBC data sources and execute queries. The following example shows how to retrieve MarkLogic data into a DataWindow. You can add the following code to the open method:
SQLCA.DBMS = "ODBC"
SQLCA.DBParm = "ConnectString='DSN=CData MarkLogic Source'"
CONNECT USING SQLCA;
dw_customer.SetTransObject(SQLCA);
dw_customer.Retrieve();
