Hello,

Can someone guru of MPS help me realize follow sample.

Everyone know that program operate with JDBC. I like to use MPS to generate

database stubs to asses into database.

Now i must create wrapers for it. Will be very nice to have such functions

as 'inline operators'.

select t.id as int id, t.name as String name, t.phoneNumber as String phoneNumber 
from userinfo t {
   System.out.println(id + ": " + name + "(" + phoneNumber + ")");
}

Is i loop, with variable definitions and automatical call into JDBC.

Please, describe common concepts and steps to make it sample?

Thanks!

You may start from creating new Concept SelectStatement that extends

Block concept from BaseLanguage. I think it should contain StatementList

node as child and some nodes to represent parameter. You language is

baseLanguage extension. For more examples you can look at

CollectionLanguage project under MPS_HOME/languages/collectionLanguage.

Alexey, this extension is difficult to do. You're going to pass block of code as parameter. I suggest you to wait with it until we have an example of such.
