Post DB Zip Enhancment Request: Limit rows for a table. Reply with quote

I'd like to see an option for a table, to limit the percent or number of rows
to be DB Zipped. For a large database, I would like to be able to take a
sample of the data only.

Thanks.

Can you create an intermidiate table?

For example,
CREATE TABLE data_sample_table AS
SELECT * FROM main_table WHERE rownum < 1000

Then you can ZIP data_sample_table table. Note that it is not required to unzip to the table with the same data_sample_table name. You can unzip to any desired table, just overide table name in unzip options.

I've considered that. For sites where I don't want to do that, though, the built-in limiter would be preferable.

Just a thought.
