Examples ¶ Here are a few simple examples of using BETWEEN with numeric and string values:your CASE is returning a string and a number which are not the same types, so if you make the 0 into a string '0' that should work better. A side note, you will still have a count of 1 for the all the values <= 100, which seems somewhat strange. Where-as if you used null instead of the 0 then it will not count, and will not have a type problem.

If the input string is 'null', it is interpreted as a JSON null value, meaning the result is not a SQL NULL, but a valid VARIANT value containing null (the difference is apparent when printing this VARIANT value).

"Snowflake supports defining and maintaining constraints, but does not enforce them, except for NOT NULL constraints, which are always enforced."
