RexCall Logic

Hi,

Is there any utility/helper class in calcite to detect and simplify such a
rexcall

AND(=($0, 1), =($0, 2))

 to false.

Thanks...

It should indeed cover that case.

Jesus added something very close to that in
https://issues.apache.org/jira/browse/CALCITE-1220:

    // condition not satisfiable
    checkSimplifyFilter(and(eq(aRef, literal1), eq(bRef, literal10),
eq(aRef, bRef)),
        "false");

You could add a new case in RexProgramTest and see whether it doe what you need.
