I'm doing a SQL query on MSSQL and I want those results written to a CSV file.

I've found numerous examples of the other way around, but I need the results to go into a CSV and it has to be done using Python.

Please help!

Here you go.
import pyodbc
import csv

class ODBCtoCSV(object):

    def __init__(self, connect='Driver={SQL Server};Server=SomeServer;Database=SomeDB;UID=SomeUser;PWD=SomePassword'):
        self.connect_string = connect

    def dump(self, sql, filename, include_headers=True):
        f = csv.writer(file(filename, 'wb'))

        cnxn = pyodbc.connect(self.connect_string)
        c = cnxn.cursor()
        c.execute(sql)

        if include_headers:
            f.writerow([d[0] for d in c.description])

        f.writerows(c.fetchall())
            
if __name__ == '__main__':
    
    query = ODBCtoCSV()
    query.dump("select * from SomeTable", "output.csv")

Open in new window

On the query.dump

Can I fit in a select statement with some where clauses?
