[Lift] Re: How to use prepareStatement to select *** from DB (two db vender)?
I have added the demo code on the Github now.
( Mabye it's a bug with DB.runQuery and DB.use in the two db
vender )
Here is the address:

Thanks very much!

Two question: (problem)
1: I don't know why the HelloWorld snippet code will be execute 2
times in this code. (See the HelloWorld.scala file.)
2: The dbDefaultConnectionIdentifier method in the Model that it works
fine when using Mapper's method such as ModelName.findAll(),
it doesn't work when using DB.runQuery and DB.use(...) --- (Maybe it
can't find the default db identifier)
The question 2 I test it many times that found this problem.
In the test app , the Hot.getHots2 and Hot.getHots3 method can't work.
I comment the code now in the HelloWorld.scala file, you can try it.
I can push the code on the github, and get this errors fatal:
unable to fork
So If anyone know what's wrong with it and I can send the demo.tar
file through the email.
Thanks very much!

Ie
val (_,result) = DB.runQuery(SELECT COUNT(*), contract_length

What is wrong with:
DB.use(FirstDB) {
firstConnection =
DB.use(SecondDB) {
secondConnection =
// do transactional query between two DBs here
}
}
Note that DB.use nests such that the transaction will only be committed when
the last DB.use block for a given ConnectionIdentifier is exited.

[Lift] Re: How to use prepareStatement to select *** from DB (two db vender)?
The users table in the OneDB, and the hots table in the TwoDB, they
are separated!
I have changed the method that like this:
###
# I specify the TwoDB for hots table.
override def dbDefaultConnectionIdentifier = bootstrap.liftweb.TwoDB
def getHots3(id : Long) = {
DB.use(bootstrap.liftweb.OneDB) {
firstConn =
DB.use(bootstrap.liftweb.TwoDB) {
conn =
DB.prepareStatement(SELECT * FROM hots WHERE id?, conn) {
stmt =
stmt.setLong(1, id)
stmt.executeUpdate()
}
}
}
}
###
But it doesn't work.

Re: [Lift] Re: How to use prepareStatement to select *** from DB (two db vender)?
It doesn't work is not sufficient to diagnose. What behavior did you get, and
what were you expecting? Were there any errors, log messages, exceptions, etc?
If so, please copy them. Finally, if you have a reproducible test case please
post it to github. I note earlier in the thread that you were fiddling with
github, so if an older example is there, please make sure it's up to date with
the most recent code.
Thanks,

What do it doesn't work mean? Does it not compile, if not, what's the
compilation error? If it's another error, what's the error? In your
example, you are not using the firstConn connection. Also, you will get an
exception if you do an executeUpdate with a SELECT statement (this is JDBC,
not Lift). You must do an executeQuery for a SELECT.
Thanks very much! :)

Thank you very much,
But it doesn't work yet, maybe because of using two db connections.
I'll test it later again.

Not sure what your problem is really, but I think you should use
DB.runQuery to execute a select statement
Ie
val (_,result) = DB.runQuery(SELECT COUNT(*), contract_length FROM +
vehicles_current v +
WHERE v.account_id=? +
GROUP BY contract_length +
ORDER BY contract_length,
List(42))

[Lift] Re: How to use prepareStatement to select *** from DB (two db vender)?
Mabye it's a bug with DB.runQuery and DB.use in the two db vender
Two question: (problem)
1: I don't know why the HelloWorld snippet code will be execute 2
times in this code. (See the HelloWorld.scala file.)
2: The dbDefaultConnectionIdentifier method in the Model that it works
fine when using Mapper's method such as ModelName.findAll(),
it doesn't work when using DB.runQuery and DB.use(...) --- (Maybe it
can't find the default db identifier)
The question 2 I test it many times that found this problem.
In the test app , the Hot.getHots2 and Hot.getHots3 method can't work.
I comment the code now in the HelloWorld.scala file, you can try it.
I can push the code on the github, and get this errors fatal:
unable to fork
So If anyone know what's wrong with it and I can send the demo.tar
file through the email.
Thanks very much!
Cheers,
Neil
