Try: SET NULL OUTPUT filename.csv UNLOAD DATA FOR tablename USING columnlist AS CSV OUTPUT SCREEN SET NULL -0- And your null fields will be just two commas with no spaces between.

Matt, Have you tried exporting as ASCII when NULL = (a space) Try it and look at the generated file. There will be no spaces between the commas for a NULL value. This is exactly what you need. Here are my rules for the use of the NULL setting: ALWAYS have NULL=-0- EXCEPT: When exporting data as ASCII, CSV, etc. When editing with a form When printing a report If you do not have NULL=-0- and you edit tables manually, you will never get a null entered in text fields. Try as you might, the value will always be a space. The exact opposite is true in forms. If null=-0- not only will your forms look ugly, but you wont know the difference between NULL and -0- When Unloading data and structure from RBASE, ALWAYS set NULL=-0- RBASE has worked like this as long as I can remember.

Well here's my problem with how it seems to work. I understand the need to visually separate null from a blank space within R:Base. So sure, when I open a table within R:Base show me some kind of value, -0- will do just fine. However when I export data from my table to say... and basic csv text file. That data should not be represented by a -0-, but nothing at all, in my opinion. That way if I want to use the data in another database, or as in this case a third party wants to use it in another database, they can do so without the other database having to understand that -0- = null. I thought about setting NULL = ' ' but even that wouldn't work, because even then the third party database would still have to know that null = ' '. I'm certainly no database guru and I really appreciate all the help I receive from you guys and gals. My only other database experience lies with MySQL and it's always been my understanding that null = nothing at all. So I guess ultimately I don't really need to know why R:Base uses text representation for null, but I need to know if there is a solution I can use to make null = nothing at all or empty. Basically if 'empty' was or possibly is a valid command, the logic I want to accomplish is R> set null empty. Is this possible? To further explain what I want, heres an example. Let's say we have a table with one row containing three fields of data; a, b, and c. Field b is null in this case. Something like this. a b c 1 text -0- text As my R:Base is setup now, if I were to export this data to a text file (csv) I get: "text","-0- ","text" The end result text file (csv) I want to achieve is: "text","","text" Thanks again for all your help with my novice problems/questions.
