If you're working with SQL and need to check the sequence value of a particular sequence, how would you do it? Is there a specific SQL command or function that you can use to retrieve the current value of a sequence? And how would you handle this if you're working with different database management systems, such as PostgreSQL, MySQL, or Oracle? Can you provide an example or two of how to check sequence values in these different systems?

Similarly, the CURRVAL operator retrieves the current value of the sequence, without incrementing it.

To employ either of these operators, you must precede them with the name or synonym of the sequence object.

It's essential to ensure that the sequence object exists within the same database context as your SQL statement.

The NEXTVAL operator allows you to access the next value in a sequence, advancing its internal counter.
