Connect to Excel Data from PowerBuilder via JDBC

The CData JDBC driver for Excel is a standards-based control that can be used from any platform or development technology that supports JDBC, including PowerBuilder. This article shows how to use the CData JDBC Driver for Excel in PowerBuilder.

This article shows how to create a basic PowerBuilder application that uses the CData JDBC Driver for Excel to perform reads and writes.

Connect to Excel Data from PowerBuilder

Follow the steps below to use the Database Painter tool to create a database profile based on an JDBC URL for Excel. You can use a database profile to save connection properties. In the Database Painter, you can graphically manipulate data as well as execute SQL queries.

1. Add the driver JAR to the PowerBuilder classpath. Set the CLASSPATH system environment variable to the path to the driver JAR, located in the lib subfolder of the installation directory.

   Note: If you are using PowerBuilder Classic, you can also add the path to the driver JAR by clicking Tools -> System Options -> Java.

2. Click Tools -> Database Painter.
3. Right-click the JDBC node and click New Profile.
4. In the Database Profile Setup dialog, enter the following:
   • Profile Name: Enter a user-friendly name for the profile.
   • Driver Name: Enter the class name of the driver, cdata.jdbc.excel.ExcelDriver
   • URL: Enter the JDBC URL.

     Connecting to Local or Cloud-Stored (Box, Google Drive, Amazon S3, SharePoint) Excel Files

     CData Drivers let you work with Excel files stored locally and stored in cloud storage services like Box, Amazon S3, Google Drive, or SharePoint, right where they are.

     Setting connection properties for local files

     Set the URI property to local folder path.

     Setting connection properties for files stored in Amazon S3

     To connect to Excel file(s) within Amazon S3, set the URI property to the URI of the Bucket and Folder where the intended Excel files exist. In addition, at least set these properties:

     • AWSAccessKey: AWS Access Key (username)
     • AWSSecretKey: AWS Secret Key

     Setting connection properties for files stored in Box

     To connect to Excel file(s) within Box, set the URI property to the URI of the folder that includes the intended Excel file(s). Use the OAuth authentication method to connect to Box.

     Dropbox

     To connect to Excel file(s) within Dropbox, set the URI proprerty to the URI of the folder that includes the intended Excel file(s). Use the OAuth authentication method to connect to Dropbox. Either User Account or Service Account can be used to authenticate.

     SharePoint Online (SOAP)

     To connect to Excel file(s) within SharePoint with SOAP Schema, set the URI proprerty to the URI of the document library that includes the intended Excel file. Set User, Password, and StorageBaseURL.

     SharePoint Online REST

     To connect to Excel file(s) within SharePoint with REST Schema, set the URI proprerty to the URI of the document library that includes the intended Excel file. StorageBaseURL is optional. If not set, the driver will use the root drive. OAuth is used to authenticate.

     Google Drive

     To connect to Excel file(s) within Google Drive, set the URI property to the URI of the folder that includes the intended Excel file(s). Use the OAuth authentication method to connect and set InitiateOAuth to GETANDREFRESH.

     Built-in Connection String Designer

     For assistance in constructing the JDBC URL, use the connection string designer built into the Excel JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.

     java -jar cdata.jdbc.excel.jar
     

     Fill in the connection properties and copy the connection string to the clipboard. A typical JDBC URL is below:

     jdbc:excel:URI='C:/MyExcelWorkbooks/SampleWorkbook.xlsx';

   👁 The JDBC data source defined in the Database Profile Setup dialog. (Salesforce is shown.)
   
5. To view and modify a table, right-click a table and then click Edit Data -> Grid.

Using Excel Data with PowerBuilder Controls

You can use standard PowerBuilder objects to connect to JDBC data sources and execute queries. The following example shows how to retrieve Excel data into a DataWindow. You can add the following code to the open method:

SQLCA.DBMS = "JDBC"
SQLCA.AutoCommit = False
SQLCA.DBParm = "Driver='cdata.jdbc.excel.ExcelDriver',URL='jdbc:excel:URI='C:/MyExcelWorkbooks/SampleWorkbook.xlsx';";
CONNECT USING SQLCA;
dw_sheet.SetTransObject(SQLCA);
dw_sheet.Retrieve();
