my priority for this macro is not the macro itself, but really because it is used in dbt-utils's integration testing for validation of OTHER macros.
calc CTE
these two coalesces are the tricky parts that need to be converted into NULLIFs or CASE WHENs? Also false needs to be replaced with 0 bc TSQL doesn't have a true & false. Here's a gist of the compiled SQL that's error-ing out. If you log into the test db (dbt-msft-serverless-db), you can debug it.
my interpretation for the logic for the first coalesce statement below, though i'm not sure in what scenario lower_bound < upper_bound could be NULL.
if lower_bound < upper_bound is not null:
return the result of the comparison: true or false (or in TSQL's case: 1 or 0)
else if lower_bound < upper_bound is NULL:
return false (i.e. 0)

the error i'm getting is Incorrect syntax near '<'. (102)
