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 FileId, ChildrenNum FROM Files WHERE FileId = '119116'")

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 (FileId, ChildrenNum) in cursor:
    print("FileId = {}, ChildrenNum = {}".format(FileId, ChildrenNum))
