update table

set thisColumn = 'this value'
where thatColumn = 'that value';

is probably technically correct but probably not the advise you were looking for.

So:
- you could create an index on thatColomn, then the above update would go faster
- you could look for another indexed column that could be added to the where clause to avoid the full table scan

Hi All,

I've a table of 10 M records and I want to update some thousand records based on a column which is not a part of any index. Please suggest the quickest way to do this.

Thanks,
Rajesh
