    Inserting nextval after sequence has reached maximum value

    What will happen when a sequence has reached the maximum value and we try to insert the nextval of the sequence?

    Eg. A sequence has a maximum value of 999 and it has crossed. Now i try to insert a value through sequence_name.nextval() and the cycle option was not mentioned while creating the sequence.

    Will oracle give a error?

    Hi,

    Oracle will definitely throw an error if the sequence exceeds the max value & cycle parameter is not set.
    The error will be ORA-08004,

    ORA-08004: sequence SEQ_TEST1.NEXTVAL exceeds MAXVALUE and cannot be instantiated

    well innila gave the correct reply. if the paramater for returning to the starting value is off then an error will be there else if cycle is present then it ll start from the beginning value. like if we have start value 1
    max value 99
    then if cycle is there then after 99 it ll start from 1 else will return a value.

    try with ALTER SEQUENCE and change the max val property or SET CYCLE property
