copying one row to another

I have a table named tblOrgRegistrations

I have a column named CDTESType and I want to transfer the data in this column to a column named SubGroup in the same table where the Agency column = CDTES

Is this correct below

UPDATE tblOrgRegistrations
SET SubGroup = CDTESType where Agency = 'CDTES'

Looks correct.  Back up your database and try it. :)

yes, it's 100% correct as long as both data types are similar!

it's correct if it's the same row.

to copy from 1 row to another row, you will need to "update with join" with the same table, read up here:
