Here’s an example code in Python to write data to an Access database using the pyodbc library import pyodbc # Define the data to be written data = [ ('John', 25, 'Male'), ('Sarah', 30, 'Female'), ('David', 22, 'Male') ] # Define the connection string to the Access database conn_str = ( r'Driver={Microsoft Access Driver (*.mdb, *.accdb)};' r'DBQ=C:pathtodatabase.accdb;' ) # Establish a connection to the Access database conn = pyodbc.connect(conn_str) # Define a cursor object to execute SQL statements cursor = conn.cursor() # Define the SQL statement to insert data into the table sql = 'INSERT INTO my_table (Name, Age, Gender) VALUES (?, ?, ?)' # Execute the SQL statement to insert data into the table row by row for row in data: cursor.execute(sql, row) conn.commit() print('Data has been written to the Access database successfully.') # Close the cursor and the connection cursor.close() conn.close() This code defines a list of data to be written to an Access database table, sets the connection string to the Access database, establishes a connection to the database, defines a cursor object to execute SQL statements, defines the SQL statement to insert data into the table, and executes the SQL statement to insert data into the table row by row using the execute() method. Finally, it prints a message to indicate that the data has been written successfully, and closes the cursor and the connection.
Write data to TXT / flat file using Python
Here’s an example code in Python to write data to a txt or flat file # Define the data to be written data = "This is a sample data that will be written to a txt file." # Define the file path and name for the txt file file_path = 'data.txt' # Open the txt file in write mode with open(file_path, mode='w') as txt_file: # Write the data to the txt file txt_file.write(data) print(f'Data has been written to {file_path} successfully.') This code defines a string data to be written to a txt file, sets the file path and name for the txt file, opens the txt file in write mode, and writes the data to the txt file using the write() method. Finally, it prints a message to indicate that the data has been written successfully.
Write Data to CSV file using Python

This code defines a 2D list of data to be written to a CSV file, sets the file path and name for the CSV file, opens the CSV file in write mode, creates a CSV writer object, and writes the data to the CSV file row by row using the writerow() method. Finally, it prints a message to indicate that the data has been written successfully.
.NET code to load data from Excel to Progress database
Here’s a sample code in C# to write data from an Excel file to a Progress database using the System.Data.Odbc namespace using System.Data.Odbc; using System.Data.OleDb; // Set up ODBC connection string string connectionString = "Driver={Progress OpenEdge 11.7 Driver};HOST=<host>;PORT=<port>;DB=<database>;UID=<username>;PWD=<password>;"; // Set up SQL insert statement string sqlInsert = "INSERT INTO <table> (col1, col2, col3) VALUES (?, ?, ?)"; // Open Excel file and read data using (OleDbConnection oleDbConnection = new OleDbConnection("Provider=Microsoft.ACE.OLEDB.12.0;Data Source=<excel file path>;Extended Properties='Excel 12.0 Xml;HDR=YES'")) { using (OleDbCommand oleDbCommand = new OleDbCommand("SELECT * FROM [<worksheet name>$]", oleDbConnection)) { oleDbConnection.Open(); using (OleDbDataReader oleDbDataReader = oleDbCommand.ExecuteReader()) { // Set up ODBC command and connection using (OdbcConnection odbcConnection = new OdbcConnection(connectionString)) using (OdbcCommand odbcCommand = new OdbcCommand(sqlInsert, odbcConnection)) { // Open ODBC connection and begin transaction odbcConnection.Open(); OdbcTransaction odbcTransaction = odbcConnection.BeginTransaction(); odbcCommand.Transaction = odbcTransaction; // Loop through Excel rows and insert into Progress table while (oleDbDataReader.Read()) { odbcCommand.Parameters.Clear(); odbcCommand.Parameters.AddWithValue("?", oleDbDataReader.GetValue(0)); odbcCommand.Parameters.AddWithValue("?", oleDbDataReader.GetValue(1)); odbcCommand.Parameters.AddWithValue("?", oleDbDataReader.GetValue(2)); odbcCommand.ExecuteNonQuery(); } // Commit transaction and close ODBC connection odbcTransaction.Commit(); odbcConnection.Close(); } } } } Note that you will need to replace <host>, <port>, <database>, <username>, <password>, <table>, and <excel file path> with your specific host, port, database, login credentials, table, and file path values, respectively. Additionally, you may need to modify the SQL insert statement and parameters to match your specific database schema and the Excel worksheet name to match your specific worksheet name.
