> {code:java}
> @Test public void testJoinOnLeftProjectWithFilterToJoin() {
> String mv = ""
> + "select \"emps\".\"empid\", \"depts\".\"name\",
> \"emps\".\"salary\"\n" +
> "from \"emps\"\n" +
> "left join \"depts\"\n" +
> "on \"emps\".\"deptno\" = \"depts\".\"deptno\"\n"
> + "where \"emps\".\"empid\" > 10";
> String query = ""
> + "select \"emps\".\"empid\", \"depts\".\"name\",
> \"emps\".\"salary\"\n" +
> "from \"emps\"\n" +
> "left join \"depts\"\n" +
> "on \"emps\".\"deptno\" = \"depts\".\"deptno\"\n"
> + "where \"emps\".\"empid\" > 40";
