A Basic Code Example

Let's look at a simple example. This will demonstrate how to connect to an Oracle database. We'll execute a query. Here's a basic example:

using Devart.Data.Oracle;
using System;

class Program
{
    static void Main()
    {
        // Define the connection string with placeholders for your specific database information
        var connectionString = "User Id=myUsername;Password=myPassword;Server=myServer;";

        // Establish a connection to the Oracle database
        using (var connection = new OracleConnection(connectionString))
        {
            connection.Open();

            // Execute a SQL command
            using (var command = new OracleCommand("SELECT * FROM myTable", connection))
            {
                using (OracleDataReader reader = command.ExecuteReader())
                {
                    // Read and print each row of the result set
                    while (reader.Read())
                    {
                        Console.WriteLine(reader["myColumn"].ToString());
                    }
                }
            }
        }
    }
}

using Devart.Data.Oracle;
using System;

class Program
{
    static void Main()
    {
        // Define the connection string with placeholders for your specific database information
        var connectionString = "User Id=myUsername;Password=myPassword;Server=myServer;";

        // Establish a connection to the Oracle database
        using (var connection = new OracleConnection(connectionString))
        {
            connection.Open();

            // Execute a SQL command
            using (var command = new OracleCommand("SELECT * FROM myTable", connection))
            {
                using (OracleDataReader reader = command.ExecuteReader())
                {
                    // Read and print each row of the result set
                    while (reader.Read())
                    {
                        Console.WriteLine(reader["myColumn"].ToString());
                    }
                }
            }
        }
    }
}

Imports Devart.Data.Oracle
Imports System

Friend Class Program
	Shared Sub Main()
		' Define the connection string with placeholders for your specific database information
		Dim connectionString = "User Id=myUsername;Password=myPassword;Server=myServer;"

		' Establish a connection to the Oracle database
		Using connection = New OracleConnection(connectionString)
			connection.Open()

			' Execute a SQL command
			Using command = New OracleCommand("SELECT * FROM myTable", connection)
				Using reader As OracleDataReader = command.ExecuteReader()
					' Read and print each row of the result set
					Do While reader.Read()
						Console.WriteLine(reader("myColumn").ToString())
					Loop
				End Using
			End Using
		End Using
	End Sub
End Class

This code snippet is enhanced with proper connection strings. It selects data from a table and prints a column value to the console. Replace myUsername, myPassword, myServer, myTable, and myColumn with your actual database details. This is how you perform a basic database operation using C# Devart.Data.Oracle.

Implement Features of Devart.Data.Oracle

Direct Mode

One of the standout features of Devart.Data.Oracle, a crucial part of any application architecture, is Direct Mode. This allows your application to work with Oracle databases without Oracle Client. It simplifies deployment. It reduces the application's overall footprint.

var connectionString = "User Id=myUsername; Password=myPassword; Direct=True; Server=myServer;";
using (var connection = new OracleConnection(connectionString))
{
    connection.Open();
    // Use the connection
}

var connectionString = "User Id=myUsername; Password=myPassword; Direct=True; Server=myServer;";
using (var connection = new OracleConnection(connectionString))
{
    connection.Open();
    // Use the connection
}

Dim connectionString = "User Id=myUsername; Password=myPassword; Direct=True; Server=myServer;"
Using connection = New OracleConnection(connectionString)
	connection.Open()
	' Use the connection
End Using

This example shows how to enable Direct Mode. Add Direct=True to your connection string.

Advanced Entity Framework Support

Devart.Data.Oracle enhances Entity Framework (EF) operations. It provides better performance and supports both EF Core and EF6. It offers a wide range of Oracle-specific features.

// Example assumes EF Core setup
using (var context = new MyDbContext())
{
    var data = context.MyEntities.Where(e => e.Property > 0).ToList();
    foreach (var item in data)
    {
        Console.WriteLine(item.Name);
    }
}

// Example assumes EF Core setup
using (var context = new MyDbContext())
{
    var data = context.MyEntities.Where(e => e.Property > 0).ToList();
    foreach (var item in data)
    {
        Console.WriteLine(item.Name);
    }
}

' Example assumes EF Core setup
Using context = New MyDbContext()
	Dim data = context.MyEntities.Where(Function(e) e.Property > 0).ToList()
	For Each item In data
		Console.WriteLine(item.Name)
	Next item
End Using

This code fetches data using EF Core. Replace MyDbContext, MyEntities, and Property with your actual context and entity names.

Bulk Operations

Bulk operations are crucial for high-performance data manipulation. Devart.Data.Oracle offers bulk copy functionality. This is useful for large data transfers.

using (var connection = new OracleConnection(connectionString))
{
    connection.Open();
    using (var bulkCopy = new OracleBulkCopy(connection))
    {
        bulkCopy.DestinationTableName = "targetTable";
        bulkCopy.WriteToServer(dataTable);
    }
}

using (var connection = new OracleConnection(connectionString))
{
    connection.Open();
    using (var bulkCopy = new OracleBulkCopy(connection))
    {
        bulkCopy.DestinationTableName = "targetTable";
        bulkCopy.WriteToServer(dataTable);
    }
}

Using connection = New OracleConnection(connectionString)
	connection.Open()
	Using bulkCopy = New OracleBulkCopy(connection)
		bulkCopy.DestinationTableName = "targetTable"
		bulkCopy.WriteToServer(dataTable)
	End Using
End Using

This code demonstrates bulk data insertion. Replace targetTable with your destination table name. dataTable should be your data source.

Integrated Performance Monitoring

Performance monitoring is built into Devart.Data.Oracle. It allows you to track and optimize database interactions.

using System;
using Devart.Data.Oracle;

class Example
{
    static void Main()
    {
        // Enable monitoring
        using (var monitor = new OracleMonitor() { IsActive = true })
        {
            // Perform database operations here
            // Monitoring will log interactions
        }
    }
}

using System;
using Devart.Data.Oracle;

class Example
{
    static void Main()
    {
        // Enable monitoring
        using (var monitor = new OracleMonitor() { IsActive = true })
        {
            // Perform database operations here
            // Monitoring will log interactions
        }
    }
}

Imports System
Imports Devart.Data.Oracle

Friend Class Example
	Shared Sub Main()
		' Enable monitoring
		Using monitor = New OracleMonitor() With {.IsActive = True}
			' Perform database operations here
			' Monitoring will log interactions
		End Using
	End Sub
End Class

Enable OracleMonitor and set IsActive to true. This starts monitoring your database operations.

Enhanced LINQ to SQL Support

LINQ to SQL transforms complex queries into efficient SQL. Devart.Data.Oracle provides optimized LINQ to SQL capabilities. It supports complex queries and transformations.

using (var context = new MyDbContext())
{
    var query = from e in context.MyEntities
                where e.PropertyName == "Value"
                select e;

    foreach (var item in query)
    {
        Console.WriteLine(item.Property);
    }
}

using (var context = new MyDbContext())
{
    var query = from e in context.MyEntities
                where e.PropertyName == "Value"
                select e;

    foreach (var item in query)
    {
        Console.WriteLine(item.Property);
    }
}

Using context = New MyDbContext()
	Dim query = From e In context.MyEntities
		Where e.PropertyName = "Value"
		Select e

	For Each item In query
		Console.WriteLine(item.Property)
	Next item
End Using

Replace MyDbContext, MyEntities, PropertyName, and Property with your actual context, entity, and property names. This example queries the database using LINQ.

Each of these features enhances your application. They make your work with Oracle databases more efficient. You have direct access, advanced EF support, bulk operations, performance monitoring, and enhanced LINQ to SQL at your disposal.

Merging IronPDF with Devart.Data.Oracle

Imagine you're working on a project where you need to generate a report from data stored in an Oracle database and then present that report as a PDF file. Here's where the combination of IronPDF and Devart.Data.Oracle comes into play. Devart.Data.Oracle is a high-performance ADO.NET provider that gives developers an efficient way to access Oracle databases from .NET applications.

Code Example of Use Case

Let's dive into a practical example to illustrate this process. Suppose we have a table named SalesReport in our Oracle database, and we want to generate a PDF report that summarizes this data. First, you'll need to install IronPDF and Devart.Data.Oracle packages via NuGet. This can be done using the NuGet Package Manager or via the Package Manager Console:

Install-Package IronPdf
Install-Package Devart.Data.Oracle

Install-Package IronPdf
Install-Package Devart.Data.Oracle

Next, here's how you could write the code to fetch data from the SalesReport table and generate a PDF:

using Devart.Data.Oracle;
using IronPdf;
using System;

class Program
{
    static void Main(string[] args)
    {
        // Connection string to Oracle Database
        var oracleConnectionString = "User Id=your_user;Password=your_password;Direct=True;Sid=your_sid;Server=your_server;";

        // SQL query to fetch data
        var sqlQuery = "SELECT * FROM SalesReport";

        // Initialize the Oracle connection
        using (var oracleConnection = new OracleConnection(oracleConnectionString))
        {
            oracleConnection.Open();

            // Execute the query
            using (var oracleCommand = new OracleCommand(sqlQuery, oracleConnection))
            {
                using (var reader = oracleCommand.ExecuteReader())
                {
                    // Initialize HTML content for PDF generation
                    var htmlContent = "<h1>Sales Report</h1><p>Generated on " + DateTime.Now + "</p>";

                    // Append database data to the HTML content
                    while (reader.Read())
                    {
                        htmlContent += $"<p>{reader["ItemName"]} - {reader["SaleAmount"]}</p>";
                    }

                    // Create a PDF from the HTML content using IronPDF
                    var renderer = new ChromePdfRenderer();
                    var pdf = renderer.RenderHtmlAsPdf(htmlContent);

                    // Save the PDF to a file
                    pdf.SaveAs("SalesReport.pdf");
                }
            }
        }

        Console.WriteLine("PDF generated successfully.");
    }
}

using Devart.Data.Oracle;
using IronPdf;
using System;

class Program
{
    static void Main(string[] args)
    {
        // Connection string to Oracle Database
        var oracleConnectionString = "User Id=your_user;Password=your_password;Direct=True;Sid=your_sid;Server=your_server;";

        // SQL query to fetch data
        var sqlQuery = "SELECT * FROM SalesReport";

        // Initialize the Oracle connection
        using (var oracleConnection = new OracleConnection(oracleConnectionString))
        {
            oracleConnection.Open();

            // Execute the query
            using (var oracleCommand = new OracleCommand(sqlQuery, oracleConnection))
            {
                using (var reader = oracleCommand.ExecuteReader())
                {
                    // Initialize HTML content for PDF generation
                    var htmlContent = "<h1>Sales Report</h1><p>Generated on " + DateTime.Now + "</p>";

                    // Append database data to the HTML content
                    while (reader.Read())
                    {
                        htmlContent += $"<p>{reader["ItemName"]} - {reader["SaleAmount"]}</p>";
                    }

                    // Create a PDF from the HTML content using IronPDF
                    var renderer = new ChromePdfRenderer();
                    var pdf = renderer.RenderHtmlAsPdf(htmlContent);

                    // Save the PDF to a file
                    pdf.SaveAs("SalesReport.pdf");
                }
            }
        }

        Console.WriteLine("PDF generated successfully.");
    }
}

Imports Devart.Data.Oracle
Imports IronPdf
Imports System

Friend Class Program
	Shared Sub Main(ByVal args() As String)
		' Connection string to Oracle Database
		Dim oracleConnectionString = "User Id=your_user;Password=your_password;Direct=True;Sid=your_sid;Server=your_server;"

		' SQL query to fetch data
		Dim sqlQuery = "SELECT * FROM SalesReport"

		' Initialize the Oracle connection
		Using oracleConnection As New OracleConnection(oracleConnectionString)
			oracleConnection.Open()

			' Execute the query
			Using oracleCommand As New OracleCommand(sqlQuery, oracleConnection)
				Using reader = oracleCommand.ExecuteReader()
					' Initialize HTML content for PDF generation
					Dim htmlContent = "<h1>Sales Report</h1><p>Generated on " & DateTime.Now & "</p>"

					' Append database data to the HTML content
					Do While reader.Read()
						htmlContent &= $"<p>{reader("ItemName")} - {reader("SaleAmount")}</p>"
					Loop

					' Create a PDF from the HTML content using IronPDF
					Dim renderer = New ChromePdfRenderer()
					Dim pdf = renderer.RenderHtmlAsPdf(htmlContent)

					' Save the PDF to a file
					pdf.SaveAs("SalesReport.pdf")
				End Using
			End Using
		End Using

		Console.WriteLine("PDF generated successfully.")
	End Sub
End Class

In this example, we start by setting up a connection to our Oracle database using the Devart.Data.Oracle OracleConnection class. Then, we fetch data from the SalesReport table using a simple SQL query. For the sake of demonstration, the data fetched is transformed into an HTML string (in a real-world scenario, you'd build up a more complex HTML document based on your data). Finally, we use IronPDF's ChromePdfRenderer class to convert the HTML string into a PDF document, which is then saved locally.
