Examples

The following example demonstrates how to use the NuoDbConnectionDataProvider to export a report to PDF:

// Create a NuoDbConnectionDataProvider using a connection string.
NuoDbConnectionDataProvider provider = new NuoDbConnectionDataProvider("your connection string here");

// Create a ListLabel reporting engine instance and assign the provider as the data source.
using ListLabel listLabel = new ListLabel();
listLabel.DataSource = provider;

// Configure export settings to generate a PDF.
ExportConfiguration exportConfiguration = new ExportConfiguration(LlExportTarget.Pdf, exportFilePath, projectFilePath);
exportConfiguration.ShowResult = true;

// Export the report to PDF.
listLabel.Export(exportConfiguration);

Remarks

The NuoDbConnectionDataProvider class extends DbConnectionDataProvider to provide connectivity to NuoDB distributed SQL databases using the NuoDB .NET Data Provider. It supports tables and views, advanced filtering, and schema-aware query construction. The provider retrieves schema information including tables, views, and foreign key relationships, and supports custom filter syntax translation for List & Label expressions.
