-- Normally you can not update/insert or delete on read only view.
-- And view becomes "read only" if you have any calculation,
-- uses any scalar function or joins
-- 
-- The trick here is to use a "instead-of trigger" where you control 
-- the update, insert and delete process 
-- 
-- Simply paste this gist into ACS SQL and step through the example.
--
-- It is a cool example how far you can go with SQL: Have fun -

-- Packing a numeric into a zoned buffer by using C runtime function.
-- The magic is done by the QXXDTOZ api and not external dependencies

-- Export_schema_script and import_schema_script uses IBM generate_sql_objects  
-- for building a export and import script in "perfect order" with IBM's SQL statements
-- in "perfect order"
--
-- After exporting a schema definition you can then use the output script 
-- to build an empty new version of the schema OR you can migrate 
-- and upgrade an existing older version of the same schema with 
-- a new layout. Perfect for CI/CD and development/production environment
-- 
-- The clone_empty_schema is a combination of first running

-- Any_sort solves the problem where you have an alphanumeric column 
-- that contains mixed numeric and alphanumeric data and you need to 
-- order both alphanumeric AND numeric at the same time 
-- 
-- Any sort returns a varchar that left adjust alpha and right adjust numeric values
