Retrieve records from MSSQLServer in Python

The below Python code will create a connection to a MSSQLServer instance, and retrieve data from it back into a variable called tblResults.

# use pyodbc for database connection import pyodbc # keep our database credentials in a store secrets = { 'host': '<db_host>', 'Name': '<db_name>', 'username': '<db_username>', 'password': '<db_password>', } # create a connection string conn_str = f"DRIVER={{ODBC Driver 17 for SQL Server}};SERVER=tcp:{secrets['host']};DATABASE={secrets['Name']};UID={secrets['username']};PWD={secrets['password']}" # create a connection to the database conn = pyodbc.connect(conn_str) # a reusable function to get data from def sql_get(sql, conn): cursor = conn.cursor() cursor.execute(sql) columns = [column[] for column in cursor.description] results = [] for row in cursor.fetchall(): results.append(dict(zip(columns, row))) return results # some variable to use in the SQL statement below something = 13 # make a database connection and return the results into a variable tblResults = sql_get( f"""SELECT * FROM tblName WHERE something='{something}'""" , conn)
