What's hilarious is even the team members couldn't respond this question asked several times before.1 person found this helpful
After experimenting, some users found it to be Java style formatting, but as it's a hidden, undocumented (hence untested and incomplete) feature, don't get your hopes up of getting it to do what you want.
If you need formatted output, I suggest you export the results to Excel.
Thanks -K-, just what I thought. SQL Developer 1.5.4 is not yet a production release - its a "we have these good ideas" release that promises much but doesn't have the honesty to identify the features that are not yet implemented. Looks like dog food to me.
Very disappointing, given the hours I have spent trying to justify to my employer why we should make the move.
Seems a bit exaggerated for a couple of missing features; there definitely is stuff in there that works and makes life easier.
The team is also pretty dedicated, but as always they can't make everybody happy. They monitor the forum to pick up bugs and generally follow up on popular feature requests (see SQL Developer Exchange).
Additionally, what might be a handicap now was certainly a blessing in the early days: sqldev is built on JDev's framework. Saved a lot of work, but also inherited bugs. I'm guessing the format feature comes from there too (that's why team members don't know how it works).
Sqldev is maturing, but IMHO priority is still balancing to much towards getting features implemented in expense of testing them and bug fixing (for sure stressed by company policy). Then we get taken away by the goodie bag, and as such the disappointment when hitting bugs and incomplete features is even bigger.
For the time being, you can try to live with the occasional quirks (as I do) or choose a much more expensive commercial program (yes, I still use TOAD now and then :p ).
Fair comments, but Oracle should not be documenting capabilities that are yet to be fully implemented without providing advisory caveats. Like I said, the time I have wasted trying to use this feature that apparently is yet to be implemented...
I'll continue to use and promote this product at work - it has great potential. But users understandably assume that documented features actually work.
Many thanks for your feedback on this matter.
The truth is that it is documented - here's a quote from the Help page:
Name: Name of the column.
Format: Format of the column. If specified, must use the Java MessageFormat formatting syntax. For detailed information and examples, see the Sun Javadoc information for the MessageFormat class in the java.text package.
hAlign: Horizontal alignment: Left or Right
vAlign: Vertical alignment: Bottom, Center, or Top
Add Column: Adds a new column.
Remove column: Removes the selected column.
Unfortunately, it doesn't work. It is a known bug, and Oracle is planning to fix it.
