Is there any way to implement an update using a JOIN? The reference manual
only allows for one table to be updated:
UPDATE table-Name [[AS] correlation-Name]
SET column-Name = Value
[ , column-Name = Value} ]*
[WHERE clause]
We have an application where need to run many queries like:
update t1 set t1.a=t2.b, t1.c=t2.d,...t1.x=(t2.a+t2.b/t2.y)
from Table1 t1 join Table2 t2 on t1.k=t2.k
where t1.x=1 and t2.y=2
We offer support on our app to most data platforms (Oracle, MySql,
SQLServer, PostgreSQL, SQLite, even Access..) and in all of them there is a
way of doing this...
Is this something missing in Derby?
Any ideas highly appreciated.
