      Description

      A query that returns no columns should perhaps raise an SQLException of some kind, I don't know, but currently it doesn't, and ij fails with a StringIndexOutOfBoundsException when it tries to display the result.

      After DERBY-4370 it is possible to construct queries that return no columns by having a select list like T1.* in a join where the USING clause contains all of T1's columns. To reproduce:

      ij> create table t(x int);
      0 rows inserted/updated/deleted
      ij> insert into t values (1),(2),(3);
      3 rows inserted/updated/deleted
      ij> select t1.* from t t1 join t t2 using ;
