is there a way to reorganize the columns (i.e. id assignment) in a table? new columns were added into the table but would like to have a more logical order to them
There’s no way to do that without dropping and recreating the table.
If you rt-click the table from the schema browser and choose “rebuild table”, Toad will give you a way to rebuild the table and then re-insert the data. This is NOT a good choice if someone might be using the table while you are rebuilding it.
For more of an online rebuild (and if I remember correctly, this method requires the DBA Module), go to the main menu -> Optimize, -> DBMS Redefinition Wizard. If you google DBMS_REDEFINITION you can get the specifics on how this works.
Check out the “rebuild table” command. It will create a script which renames the current table, gives you the ability to reorganize the columns in a create
table command, creates the table, then reinserts the data from the original table. Very handy!
If I recall correctly it has options for keeping the original renamed table. Very helpful when you are initially “playing” with the concept and as an automatic
backup, just in case.

This works for me, thanks, have not used “Rebuild” before. As I really only have this need in development phases, typically I am the only person accessing the tables.
Small suggestion. Do not reorganize table just because of column order, ever.
