Result of using wrong query
Saturday, October 2, 2010
I accidentally use wrong query to update record!!! OMG!
All the records in that column become that value. How? If I can't change back to their original value and I will be dead.
Lucky me. Phew! I have open the table previously and so I can change back their original value BUT it have 230+ record waiting for me. No choice~ I have to change back one by one.
Update [table_name]set [column_name] = '[value] ';
commit;
