You can restrict sequence access by assigning user privileges to the _Sequence metaschema table. The Can–Read privilege grants users permission to read the current value of a sequence with the CURRENT–VALUE function or to increment and read the next value of the sequence with the NEXT–VALUE function. The Can–Write privilege grants users permission to change the current value of a sequence with the CURRENT–VALUE statement.
