Thank You Patrick. I consider Your solution as a workaround as it
uses a temporary table.

As far as I know, PL/Tcl directly supports dynamic table names - but
now I have difficulties to specify a literal value which should not
be treated as column name but as varchar-value.

Please see my other post for details.
