> The unit test in RelToSqlConverterTest:
> {code:java}
> @Test void testProjectScalarSubquery() {
> final String sql = "SELECT \"EMPNO\", (SELECT COUNT(*) AS \"c\"\n" +
> "FROM \"EMP\"\n" +
> "WHERE \"MGR\" < \"t\".\"MGR\") AS \"$f1\"\n" +
> "FROM \"EMP\" as \"t\"\n" +
> "WHERE \"SAL\" > 10";
> final String expected = "SELECT \"EMPNO\", (SELECT COUNT(*) AS \"c\"\n" +
> "FROM \"SCOTT\".\"EMP\"\n" +
> "WHERE \"MGR\" < \"t\".\"MGR\") AS \"$f1\"\n" +
> "FROM \"SCOTT\".\"EMP\"\n" +
> "WHERE CAST(\"SAL\" AS DECIMAL(12, 2)) > 10.00";
> sql(sql)
> .schema(CalciteAssert.SchemaSpec.JDBC_SCOTT)
> .withCalcite()
> .ok(expected);
> } {code}
> The expected Sql should be:
> {code:java}
> final String expected = "SELECT \"EMPNO\", (SELECT COUNT(*) AS \"c\"\n" +
> "FROM \"SCOTT\".\"EMP\"\n" +
> "WHERE \"MGR\" < \"t\".\"MGR\") AS \"$f1\"\n" +
> "FROM \"SCOTT\".\"EMP\" as \"t\"\n" +
> "WHERE CAST(\"SAL\" AS DECIMAL(12, 2)) > 10.00"; {code}
> "SCOTT"."EMP" should have the alias t.
