ALM11 inserting a value to user define field based on SQL select command

hi,

I have a situation which i need to pull a name from the users table and place it in the RUN table.

we maintain a uniqe ID for each tester but we were requested to show also the full name which this information is kept in different database.

can i have in my workflow a query that select the username full name based on this uniqe id and write it in a dedicated field?

tha main idea is something like this:

RUN."USER_FULLNAME" = select full_name from USERS INNER JOIN RUN on USERS.ID =RUN.ID 

is is possible?

thanks in advanced.

Lior
