-- With this style of SQL, you can search the IFS by file name, or by creation date, or both!
-- In fact, it is simple to search by any criteria you'd like to use.

--
-- Find files within the IFS where:
--   --> The name starts with "P"
--   --> The file suffix is ".txt"
--   --> The file was created on January 10, 2022

-- Features Used : This Gist uses qsys2.user_storage
--
-- Background: We need to see user profiles trending and approaching limits!

-- Subject: The request... find and query the most recent SNTP activity log
-- Author: Scott Forstie  
-- Date  : June, 2022
-- Features Used : This Gist uses MESSAGE_QUEUE_INFO, rtrim, hex, hextoraw, interpret, IFS_READ_UTF8, and CTEs
--
-- Background: Many clients use an Simple Network Time Protocol (SNTP) client to keep the current time
--             on their IBM i in relative sync with a time server.
--             On the IBM i, the TCP9105 message appears in the System Operator message queue, 
--             pointing the admin to a log of SNTP activity.

-- Subject: The idea... discover MTIs and replace them with permanent indexes
-- Author: Scott Forstie  
-- Date  : June, 2022
-- Features Used : This Gist uses QSYS2.MTI_INFO, REPLACE(), QSYS2.CONDIDXA, RUNSQL CL command, and TIMESTAMPDIFF
--
-- Background:
-- The SQL Query Engine (SQE) recognizes when an index would be beneficial, 
-- and sometimes creates an index known as a Maintained Temporary Index (MTI).
-- The MTI can be removed by SQE for many reasons.

-- Subject: The idea... open up SQL to sending text (SMS) messages. Surely this idea is well within our grasp. To capture the idea fully implies that the complexity needs to be encapsulated.
-- Author: Scott Forstie  
-- Date  : May, 2022
-- Features Used : This Gist uses QSYS2.HTTP_GET, QSYS2.HTTP_POST, SQL PL, and wrap
--
-- Step 1:
-- Decide on an SMS provider service to use. 
-- This example is based upon Twilio, but there are many other services (TextMagic, Vonage, and others) that provide similar support.
