Connecting Python to SQL Server

Chapter 162: Connecting Python to SQL Server

Section 162.1: Connect to Server, Create Table, Query Data

Install the package:

$ pip install pymssql
import pymssql
SERVER = "servername"
USER = "username"
PASSWORD = "password"
DATABASE = "dbname"
connection = pymssql.connect(server=SERVER, user=USER, password=PASSWORD, database=DATABASE)
cursor = connection.cursor() # to access field as dictionary use cursor(as_dict=True)
cursor.execute("SELECT TOP 1 * FROM TableName")
row = cursor.fetchone()
## CREATE TABLE
cursor.execute("""
CREATE TABLE posts (
post_id INT PRIMARY KEY NOT NULL,
message TEXT,
publish_date DATETIME
)
""")
## INSERT DATA IN TABLE
cursor.execute("""
INSERT INTO posts VALUES(1, "Hey There", "11.23.2016")
""")
commit your work to database connection.commit()
## ITERATE THROUGH RESULTS
cursor.execute("SELECT TOP 10 * FROM posts ORDER BY publish_date DESC")
for row in cursor:
print("Message: " + row[1] + " | " + "Date: " + row[2])
if you pass as_dict=True to cursor
print(row["message"])
connection.close()

You can do anything if your work is related with SQL expressions, just pass this expressions to the execute method(CRUD operations).

For with statement, calling stored procedure, error handling or more example check: pymssql.org
