Use regex in Spark SQL for super-powerful string processing! ​With the RLIKE or REGEXP_EXTRACT functions, you can: ​Validate formats (e.g., emails, dates). ​Extract specific data (e.g., codes, values). ​Filter complex rows. ​Example: WHERE column RLIKE 'pattern' ​#SparkSQL

QUALIFY clause in Spark SQL filters the results of window functions (like RANK(), ROW_NUMBER()) without requiring subqueries. It acts like a HAVING clause specifically for window functions,simplifying your queries.QUALIFY RANK() = 1 to get the first record in each group.#SparkSQL
