Please help.
what is the proper syntax for undoing an update made to a column.
I've accidentally updated a column in a table and I want to put back the previous values in that column. Thanks.

If you issued a commit then you have to do some type
of recovery. If not simply ROLLBACK.
If committed then we need more info.
Are you using logminer?
Are you using flashback query?
Do you have an export of table with old value?
Do you know what old value is and records to update? If so just issue update command
