Diff between FULL and PARTIAL unloads

Dear Experts,

I have a small confusion over Unloads.

I came across 2 words "FULL UNLOAD" and "PARTIAL UNLOAD" while going through my project specifications.

I presume like this:

FULL UNLOAD : Unload all the data from a table
(Select col1, col2, col3 from TABLE)

PARTIAL UNLOAD : Unload a part of the data based on some selection criteria.
(Select col1, col2, col3 from TABLE WHERE cond-1 and cond-2)

Can anyone suggest whether I am on right track or out of track.

Hello,

I'd suggest there are multiple "partials".

Some, not all of the rows.

Some, not all of the columns.

Combinations of the above.

Yes, i believe you are on the right track

Hi dick,

thanks for ur reply.

As you said above, I got business requirement on which criteria we need to take the unloads. They just need data only from a particular data which will be in another control table and some other project specific requirement. I have started working on that.

I am requesting you for any technical papaers or links related to partila unloads to get more knowledge on this area.

You're welcome

I believe partial unloads are kinda like reports - it just depends on what you need to meet your requirement. Rows/columns would be custom selected for the requirement.

I'm not aware of any special papers or web sites that would help.

Possibly, i do not understand the question. If you provide more info on what yo are looking for, someone may have suggestions.

Hi dick,

I am looking for some technical papers or web-links on LOAD and UNLOAD utilities, as I have been working on BMC Utilities all the time as part of my project.

So I think it is the right time to get more and more knowledge on this area. If anybody can help me out on this, I can do some research on these two utilities.

If there are any DBA's in our group, they can be sort out this.

Hello M K K,

At the top of each web page there is a "Manuals" link. There is an entire section of database manuals and many of the current versions of DB2 are available. The manual you may be most interested in is the Utility Guide.

Both LOAD and UNLOAD are convered extensively.

Yes dick,

The Utility Guide is very helpful and contains much more information.

Thanks a lot.
