extracting data into pdf form from oracle

Hello!

Data from Oracle and convert it to PDF, see below the steps:

• Step -1 : Connect to the Oracle database using an appropriate driver such as the Oracle Data Provider for .NET (ODP.NET) in C#.
• Step -2: Write a query to select the data that you want to extract. You can use SQL to query the database.
• Step -3: Iterate over the result set returned by the query and format it into a suitable structure for exporting to PDF. You can use a library such as iTextSharp to generate PDF documents in C#.
• Step -4: Save the generated PDF file to a desired location.

Here is some sample C# code that shows how to extract data from Oracle and convert it to PDF using iTextSharp:

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

    // Create command to select data
    var command = new OracleCommand(sql, conn);

    // Execute command and get data reader
    using (var reader = command.ExecuteReader())
    {
        // Create new PDF document
        var doc = new Document();

        // Create PDF writer and attach it to document
        var writer = PdfWriter.GetInstance(doc, new FileStream(outputFilePath, FileMode.Create));
        doc.Open();

        // Iterate over data reader and add rows to PDF table
        while (reader.Read())
        {
            var table = new PdfPTable(reader.FieldCount);

            for (int i = 0; i < reader.FieldCount; i++)
            {
                table.AddCell(reader.GetValue(i).ToString());
            }

            doc.Add(table);
        }

        // Close PDF document
        doc.Close();
    }
}

This code assumes that you have already established a connection to the Oracle database using an appropriate connection string, and have defined the SQL query to select the data you want to extract in the sql variable.
