2. Fill out the following pre-review checklist:

   • I am adding a new automated test(s) to verify correctness of my new code
     • If this test skips Local Testing mode, I'm requesting review from @snowflakedb/local-testing
   • I am adding new logging messages
   • I am adding a new telemetry message
   • I am adding new credentials
   • I am adding a new dependency
   • If this is a new feature/behavior, I'm adding the Local Testing parity changes.
   • I acknowledge that I have ensured my changes to be thread-safe. Follow the link for more information: Thread-safe Developer Guidelines

3. Please describe how your code solves the related issue.

   When checking to use self.limit_ or n in the select statement limit function, we first check if self.limit_ is true. The issue with that is if self.limit_ is 0, it always evaluates to false and uses n instead.

hey @sfc-gh-fhe , the local testing tests are failing
I believe you need to apply your fix to this part of code: https://github.com/snowflakedb/snowpark-python/blob/main/src/snowflake/snowpark/mock/_select_statement.py#L521-L527
then local testing tests shall pass

This isn't just for df.show(). It's for df.limit(). I suggest updating this description.

This worked fine for df.collect() and df.count(). I believe it was just a df.show() issue
