SQL databases traditionally don't have a built-in array data type. This means you can't directly store a list of values within a single column. To work with lists, you need to use workarounds. One common approach is to store the array elements as a comma-separated string within a single column. Another approach is to create a separate table to store the array elements, linking them to the main table using a foreign key. The choice depends on the specific use case and the complexity of the data. Using a separate table is often preferred for larger datasets or more complex queries, as it allows for more efficient querying and manipulation of the array elements. The string approach is simpler for smaller datasets but can lead to performance issues with complex queries.
