Get data from pandas into a SQL server with PYODBC

Get data from pandas into a SQL server with PYODBC

To get data from a Pandas DataFrame into a SQL Server database using pyodbc, you can follow these steps:

  1. Install Required Libraries:

    First, make sure you have the required libraries installed. You'll need pandas for working with DataFrames and pyodbc for connecting to SQL Server:

    pip install pandas pyodbc

  2. Import Libraries:

    Import the necessary libraries at the beginning of your Python script:

    import pandas as pd import pyodbc

  3. Create a DataFrame:

    Create a Pandas DataFrame with the data you want to insert into the SQL Server database:

    data = { 'Column1': [1, 2, 3], 'Column2': ['A', 'B', 'C'] } df = pd.DataFrame(data)

  4. Connect to SQL Server:

    Set up a connection to your SQL Server database using pyodbc:

    connection_string = 'Driver={SQL Server};' connection_string += 'Server=server_name;' connection_string += 'Database=database_name;' connection_string += 'Trusted_Connection=yes;' # Use integrated authentication conn = pyodbc.connect(connection_string)

    Replace 'server_name' and 'database_name' with the actual server and database names.

  5. Insert Data into SQL Server:

    Use the to_sql() method of the Pandas DataFrame to insert data into a SQL Server table:

    table_name = 'TableName' # Replace with the actual table name df.to_sql(table_name, conn, index=False, if_exists='append')

    In this example, the if_exists parameter is set to 'append' to add the data to the existing table. You can change it to 'replace' or 'fail' as needed.

  6. Close Connection:

    Don't forget to close the connection when you're done:

    conn.close()

Putting it all together, your script will look like this:

import pandas as pd import pyodbc # Create a DataFrame data = { 'Column1': [1, 2, 3], 'Column2': ['A', 'B', 'C'] } df = pd.DataFrame(data) # Connect to SQL Server connection_string = 'Driver={SQL Server};Server=server_name;Database=database_name;Trusted_Connection=yes;' conn = pyodbc.connect(connection_string) # Insert data into SQL Server table table_name = 'TableName' df.to_sql(table_name, conn, index=False, if_exists='append') # Close connection conn.close()

Replace 'server_name', 'database_name', and 'TableName' with your actual server, database, and table names.
