Example 46 with HepProgram

use of org.apache.calcite.plan.hep.HepProgram in project calcite by apache.

the class RelOptRulesTest method testReduceConstants.

@Test
public void testReduceConstants() throws Exception {
    HepProgram program = new HepProgramBuilder().addRuleInstance(ReduceExpressionsRule.PROJECT_INSTANCE).addRuleInstance(ReduceExpressionsRule.FILTER_INSTANCE).addRuleInstance(ReduceExpressionsRule.JOIN_INSTANCE).build();
    // NOTE jvs 27-May-2006: among other things, this verifies
    // intentionally different treatment for identical coalesce expression
    // in select and where.
    // There is "CAST(2 AS INTEGER)" in the plan because 2 has type "INTEGER NOT
    // NULL" and we need "INTEGER".
    final String sql = "select" + " 1+2, d.deptno+(3+4), (5+6)+d.deptno, cast(null as integer)," + " coalesce(2,null), row(7+8)" + " from dept d inner join emp e" + " on d.deptno = e.deptno + (5-5)" + " where d.deptno=(7+8) and d.deptno=(8+7) and d.deptno=coalesce(2,null)";
