How to Export Sql Server Result to Excel in Python

Question

I'm working with our own framework

I want to export sql server result set (queried one) to excel using ion python.

Inside the python file I can call that sql query result.

Then I want to export that query result in to excel with headers.

That means that once I call the python file, that query result should be saved as an excel spreadsheet.

Please any one can help me to make this correctly?

Answer 1

I would do this with pyodbc(for interacting with the db) and pandas (for manipulating data and exporting as spreadsheet).

Here's a simple example:

import pyodbc
import pandas as pd

cnxn = pyodbc.connect(< db details here >)
cursor = cnxn.cursor()
script = """
SELECT * FROM my_table
"""

cursor.execute(script)

columns = [desc[0] for desc in cursor.description]
data = cursor.fetchall()
df = pd.DataFrame(list(data), columns=columns)

writer = pd.ExcelWriter('foo.xlsx')
df.to_excel(writer, sheet_name='bar')
writer.save()

Read through the docs and you'll be fine.

== UPDATE ==

For more recent versions of pandas this is a better way to process the SQL query:

import pyodbc
import pandas as pd

cnxn = pyodbc.connect(< db details here >)
script = """
SELECT * FROM my_table
"""

df = pd.read_sql_query(script, cnxn)

Answer 2

import pandas as pd
import xlsxwriter
import pyodbc


conn = pyodbc.connect('Driver={SQL Server}; Server=ServerIP; uid=UID; pwd=Password; Trusted_Connection=No;')
 with pd.ExcelWriter("Output.xlsx", engine="xlsxwriter", options = {'strings_to_numbers': True, 'strings_to_formulas': False}) as writer:
        try:
            df = pd.read_sql("Select * from Orders", conn)
            df.to_excel(writer, sheet_name = "Sheet1", header = True, index = False)
            print("File saved successfully!")
        except:
            print("There is an error")
