There are two options - implicit storages in MV (MV without TO) and explicit (table created in advance) (MV with TO). | |
And I have not been using MV without TO for a long time. Because it’s much more obvious and convenient to stupidly drop MV and create a new one. | |
# alter MV with implicit storage .inner (without TO) | |
1. stop ingestion | |
2. detach table MVX | |
3. alter table `.inner.MVX` add column ..... | |
4. attach MATERIALIZED VIEW MVX as select new_SELECT_..... |

# Most of this was adapted from | |
# http://matt.might.net/articles/compiling-up-to-lambda-calculus/ | |
# Python's lambda expressions are turing-complete. To show this, we will | |
# implement the "Lambda calculus" which is another way of saying "We're so manly | |
# we don't even NEED if statements!" The lambda calculus was invented in the | |
# 1930s, and it can solve any computable problem just by using anonymous | |
# functions that each take one argument and return one value, function | |
# application, and variable references. No jumps or GO TO's needed. |
