exception sequence.nextval maxvalue? (oracle sql) -


i want catch specific exception thrown when sequence.nextval reaches maxvalue in oracle?

i don't want use exception when others; want catch specific exception logger.

you can declare user defined exception , associate exception code -8004 (the code of exception raised when sequence exceeds maximum value) using pragma exception_init() , catch specific exception. here example:

sql> declare   2    l_ex_max_val exception;   3    pragma exception_init(l_ex_max_val, -8004);   4    l_val number;   5  begin   6    l_val := gen_val.nextval;     -- kind of assignment allowed    7  exception                       -- in 11g , further versions. in earlier versions   8    when l_ex_max_val             -- use select statement   9    dbms_output.put_line('error! sequence gen_val exceeds max value');  10  end;  11  /  error! sequence gen_val exceeds max value  pl/sql procedure completed  sql>
