¿Cuál es una limitación de SQL de AMC?

The correct answer is that some common SQL functions are not currently supported. Amazon Marketing Cloud (AMC) SQL is based on Presto SQL, but it has specific limitations and does not support every function available in standard SQL or other Presto implementations. Users often encounter situations where a particular function they are accustomed to using in other SQL environments is not available in AMC. The other options are incorrect. You can join tables from different datasets within AMC, provided they are accessible and properly configured. You also can filter query results based on date ranges; date filtering is a fundamental capability for analyzing marketing data.
