> Currently, converting *TableFunctionScan* to sql is not supported, doing this will cause exception.
> Add the following test case in *RelToSqlConverterTest* to reproduce.
> {code:java}
> @Test public void testTableFunctionScan() {
> final String query = "SELECT *\n"
> + "FROM TABLE(DEDUP(CURSOR(select \"product_id\", \"product_name\"\n"
> + "from \"product\"), CURSOR(select \"employee_id\", \"full_name\"\n"
> + "from \"employee\"), 'NAME'))";
> final String expected = "SELECT *\n"
> + "FROM TABLE(DEDUP(CURSOR ((SELECT \"product_id\", \"product_name\"\n"
> + "FROM \"foodmart\".\"product\")), CURSOR ((SELECT \"employee_id\", \"full_name\"\n"
> + "FROM \"foodmart\".\"employee\")), 'NAME'))";
> sql(query).ok(expected);
> }
> {code}
> The stack trace of exception is
