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 Filesize, Filename FROM Notes WHERE FilePath = '/documents/doc.txt'")

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 (Filesize, Filename) in cursor:
    print("Filesize = {}, Filename = {}".format(Filesize, Filename))
