Why do you need two tables in your update?
Its not really a nested query but an Update statement where you use a select
statement to help qualify the Update.
See the standard SQL syntax on this.

Hi,
I think , you can't do that.
Instead use nested queries (I am not sure Derby supports nested queries
though).

Can we use 2 or more tables in UPDATE clause?
eg. UPDATE T1, T2
SET T1.name = 'abc'
WHERE T1.id = T2.id
