Hi

I have got a scheduled task in place that moves information from 1 database (Firebird) to another (MySQL). The issue that i have, is that some information that goes into the MySQL database, also needs to be in ANOTEHR MySQL database, which is stored on the same server.

Rather than modifying the scheduled task to do 2 updates, is it possible to create a trigger, that would move selected data into the other database.

E.g. If account = "041" then copy field A, B, C, D into the other database

Is this possible?

Thanks very much

PS - high point score as it would be very valuable to me

Yes, it is absolutely possible, as long as the server is MySQL 5.0 and the databases are hosted by the same MySQL server instance.

The script below gives you an idea on how to start.  You will need another trigger for capturing UPDATE events and another for DELETE events, if appropriate:

create database db1;
create database db2;
use db1;
create table test (id int unsigned not null auto_increment primary key, name varchar(15), created timestamp);
use db2;
create table test_target(id int unsigned not null primary key, name varchar(15), friend varchar(15));
use db1;
delimiter ||
create trigger test_ins after insert on test
for each row begin
insert into db2.test_target (id, name) values (new.id, new.name);
end;
||
delimiter ;
insert into test (name) values ('Todd');
select * from db2.test_target;
