Reset sequence after data import

Question

Hi all,
I've got a problem where we import data into a table with an auto-incremented field for a primary key. After the data import, I can drop the sequence, check the max(primary key), and re-create it to start at the max value + 1. My problem is that I need to do this for a large number of tables and don't know how to write a script to do it. In the Create Sequence command, whenever I try to use a variable in the "START WITH" clause, I get an error.
Thanks in advance,
Raymond

Answer 1

Spool sequence creation scipt result in a file and then run it.
Or use dynamic sql.
Or You can "drive" sequence forward issuing select myseq.nextval from dual; apropriate times. If You need "drive" sequence backwards alter it with increment -1, issue select myseq.nextval from dual; apropriate times and alter it with previous increment.
