I just realized that the information in the SYSSEQUENCES table does not actually provide enough information to recreate the sequence item.

For instance ... if you create a sequence and specify an increment of 1 that it should cache 10 values ... and use the sequence once ... the last assigned sequence column will contain a value 10 times the increment value ... even though the sequence was only used once.  I'm assuming the cached values are stored in the data area.

Oddly enough ... I noticed that, if you alter the sequence to turn OFF the cache, the maximum assigned value in the SYSSEQUENCES table does *not* get fixed ... and the next value generated by the sequence will be based off the last cached value.
