test for `insert_by_period` is failing... don't know why

[dataders]

@davidclarance maybe you can help me with this? happy to give more context later -- just jotting this down for now

test's compiled SQL

-- setup

with a as (

    select * from "dbt-msft-serverless-db"."test"."test_insert_by_period"

),

b as (

    select * from "dbt-msft-serverless-db"."test"."expected_insert_by_period"

),

a_minus_b as (

    select "id", "created_at" from a

    except

    select "id", "created_at" from b

),

b_minus_a as (

    select "id", "created_at" from b

    except

    select "id", "created_at" from a

),

unioned as (

    select 'a_minus_b' as which_diff, * from a_minus_b
    union all
    select 'b_minus_a' as which_diff, * from b_minus_a

)

select * from unioned

results

which_diff	id	created_at
b_minus_a	3	2018-02-02
b_minus_a	4	2018-03-02
b_minus_a	5	2018-04-02
b_minus_a	6	2018-05-02
