After Connecting, you can execute a SQL statement and retrieve the results.

SELECT Procedure

You will need to obtain a cursor before executing any SQL. Once you have one, you can use the cursor's execute method.

cursor = cnxn.cursor()
cursor.execute("SELECT Snippet_Title, ContentDetails_ItemType FROM Groups WHERE Id = 'S'")

Iterating over the Results

You can use a for loop to iterate over the rows of the resultset. Each row is presented as a tuple containing column values:

for (Snippet_Title, ContentDetails_ItemType) in cursor:
    print("Snippet_Title = {}, ContentDetails_ItemType = {}".format(Snippet_Title, ContentDetails_ItemType))
