how to close connection to myself with cubesql

how to close connection to myself using cubesql?

This does not work at all for myself but for other clients

Dim rs as RecordSet = dbfakt.SQLSelect(“SHOW CONNECTIONS”)
dim connectionID as string= rs.field(“ID”).StringValue
dbfakt.SQLExecute "CLOSE CONNECTION "+connectionID

Why not just dbfakt.close ?

Sometimes it’s so easy, thanks
