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 Id, displayName FROM DirectoryRoles WHERE Id = 'Jq74mCczmFXk1tC10GBs'")

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 (Id, displayName) in cursor:
    print("Id = {}, displayName = {}".format(Id, displayName))
