SQL Server and Snowflake both support the COALESCE function. This function returns the value of its first non-NULL argument. If all arguments have NULL values, it returns NULL. Unlike ISNULL or IFNULL(NVL), COA
The EQUAL_NULL function is also one of the Snowflake functions missing in SQL Server. This function compares two arguments and returns TRUE if they are equal and FALSE if not. Unlike regular equality operations, EQUAL_NULL is NULL-safe which means it considers NULLs as equal. Therefor...
When the data source is Snowflake, the operations are translated into a SQL query and then executed in Snowflake to improve performance. However, because this translation requires almost a one-to-one translation of Spark SQL operators to Snowflake expressions, not all of Spark SQL operators can...

However, from a database perspective, we also need to take into consideration SQL Server collations as these “bad boys” define not only code pages but also the rules on how to sort and compare characters. Figure 2 shows that e.g. character “w” is always encoded as decimal 119 ...
