Calling two different databases from tcl

Hello

I got two db’s, sqlite and sqludv, first one is the local SQLite and the second one is a remote MS-SQL. If I connect with the database-inbound protocol in the GUI I can just choose Database Connection.
The question is: If I from inside a tcl want to decide which db to Select from, how can I do that.

Is there away to choose DB_CONNECTION from inside the tcl.

#set row [dblookup ‘ssi_afvigelser’ ‘579000012029’1]
#echo $row
