[Bug] snowflake__create_table_as contract enforcing incorrect sql code

[tphillip33]

Is this a new bug in dbt-snowflake?

• I believe this is a new bug in dbt-snowflake
• I have searched the existing issues, and I could not find an existing issue for this bug

Current Behavior

I have created a custom materialization which is modifying the compiled_code and removing columns for final output, then passing the modified code to create_table_as. This is erroring on the fields removed in the contracts.

  {%- set exclude_columns = config.get('exclude_columns', default=['METADATA$ACTION','METADATA$ISUPDATE','METADATA$ROW_ID']) -%}

  {%- set tmp_columns = adapter.get_columns_in_relation(tmp_relation_src) -%}
  {%- set collist = get_merge_update_columns(none, exclude_columns, tmp_columns) -%}
  {%- set tmp_relation_query =  'SELECT \n' ~ collist | join(',\n') ~ '\n FROM ' ~ tmp_relation_src -%}
...
    {%- call statement('main', language=language) -%}
      {{ create_table_as(False, target_relation, tmp_relation_query, language) }}
    {%- endcall -%} 

{% macro snowflake__create_table_as(temporary, relation, compiled_code, language='sql') -%}
is enforcing the contract on a variable "sql", which is not defined instead of passed variable named "compiled_code".
{{ get_assert_columns_equivalent(sql) }}
should be
{{ get_assert_columns_equivalent(compiled_code) }}

Expected Behavior

Contracts should be enforced on the code passed to the create_table_as() macro.

Steps To Reproduce

Create a custom materialization which modifies the compiled_code.
Create a contract on the table, excluding the columns which are listed in "exclude_columns".
Run materialization

Relevant log output

This model has an enforced contract that failed.
  Please ensure the name, data_type, and number of columns in your contract match the columns in your model's definition.   

  | column_name       | definition_type | contract_type | mismatch_reason     |
  | ----------------- | --------------- | ------------- | ------------------- |
  | METADATA$ACTION   | TEXT            |               | missing in contract |
  | METADATA$ISUPDATE | BOOLEAN         |               | missing in contract |

I should say, I have already overridden the code with my own version and fixed my current issue by changing the "compiled_code" variable to "sql", the same as other instances of the code.

{% macro snowflake__create_table_as(temporary, relation, sql, language='sql') -%}
...
        (
          {%- if cluster_by_string is not none -%}
            select * from (
              {{ sql }}
              ) order by ({{ cluster_by_string }})
          {%- else -%}
            {{ sql }}
          {%- endif %}
        );
 ...
     {{ py_write_table(compiled_code=sql, target_relation=relation, table_type=table_type) }}

@MichelleArk does the behavior (and resolution via using sql instead of compiled_code) matches your expectations?
If yes we should close this then.
