Date-based query Q
This is probably a no-brainer... We have some date-based data for which most days have several records but where some days have none. I'm COUNT()ing the number of records for each day (between day x and day y) and need a record set that also includes a row for those days which have no records: UkDate Total 1/1/20035 2/1/20036 3/1/20030 4/1/20036 I could post-process the record set to achieve this, but is there any way in 9i to do an aggregate query with an outer join on a date range (if that makes sense)? Someone made the suggestion of creating another table with a row for every day under the sun in it, against which you could inner join the main query, but I'm not keen on that (that is just a gut response though). Any ideas?

Dump table to file, edit and reimport
In Sybase's ASA there was an "unload" command which wrote to a text file the SQL to recreate a table, along with all it's data which running the SQL then imported. This allowed you to very easily dump a table, edit it's structure and suck the data back in. The closest thing I've found in Oracle is right-clicking on a table | Data Management | Export. However, we're not running the Oracle Management Server (just because we don't know how to set that up yet), so this functionality isn't available. Barring installing OMS, is there a quick and dirty way to do this? And, if the answer is "no", is OMS easy to set up?

In the main, I absolutely agree (i.e. I don't think lookup tables are inherently "bad"). However, in this particular instance, the check constraint is a perfect solution (I won't bore you with the reasons why). -- Aidan Whitehall <[EMAIL PROTECTED]> Macromedia ColdFusion Developer Fairbanks Environmental Ltd +44 (0)1695 51775 This e-mail has been scanned for all viruses by Star Internet.

RE: Restricting the range of values in a field
>Yes. Read up on check constraints. Thanks for everyone's suggestions and code. I'll go with the check constraint in this instance because 10-or-so lookup tables with 2-to-5 values in each that will never change seems like overkill. Plus, the other developer here isn't a fan of lookup tables where the range of values are known to be static and he'd shout at me ;-) Thanks again! -- Aidan Whitehall <[EMAIL PROTECTED]> Macromedia ColdFusion Developer Fairbanks Environmental Ltd +44 (0)1695 51775 This e-mail has been scanned for all viruses by Star Internet.

Restricting the range of values in a field
Is there any way you can specify that the only permissible values (is it called a domain?) that can be entered in varchar2 field in an Oracle table to, for example, A, B and C? We can restrict what values users can enter at the application level, but it would be nice to be able to also restrict what can be entered at the database level, in case other means of entering data are ever used or if the application layer fails, for whatever reason, to trap an unwanted value.

Right()
Please don't laugh. What is the equivalent of a Right() function in Oracle? I want to be able to sort a column numerically whose string contents takes the format "v1, v2, v3, v4". I was after something like: ORDER BY Cast(Right(lt_tk_id, Length(lt_tk_id - 1)) as int) but it's not playing nice. Order by Right(lt_tk_id, 1) gives the same error, so I assume that's where it's falling down. I've searched everywhere I can think of for "right function", Oracle online docs, Enterprise Manager docs, Google, but nothing seems to come close. BTW, is it my imagination or do the docs leave a lot to be desired?
