-- Pass a flat file consisting of Sequence Name and New Values as a parameter to this sql file. -- set_new_seq_values.sql define SEQ_NAME=&1 define NEW_VAL=&2 set pages 0 set ver off set wrap off set feed off set term off col old_inc_val noprint new_value old_inc_val col cur_inc_val noprint new_value cur_inc_val select INCREMENT_BY old_inc_val from user_sequences where sequence_name='&SEQ_NAME'; select ( &NEW_VAL - &SEQ_NAME..NEXTVAL ) cur_inc_val from dual; alter sequence &SEQ_NAME INCREMENT BY &&cur_inc_val; select &SEQ_NAME..NEXTVAL from dual; alter sequence &SEQ_NAME INCREMENT BY &&old_inc_val; set term on prompt select 'Sequence &SEQ_NAME has been set to &NEW_VAL..' from dual; prompt EXIT
