########## File path: core/src/test/java/org/apache/calcite/test/RexProgramTest.java ########## @@ -624,6 +624,13 @@ private RexProgramBuilder createProg(int variant) { case_(isNotNull(i0), i0, i1), c01), is(true)); + final RelDataType intArray = typeFactory.createArrayType(intType, -1); + RexInputRef inputRef = rexBuilder.makeInputRef(intArray, 0); + RexNode rexNode = rexBuilder.makeCall( + SqlStdOperatorTable.ITEM, + inputRef, + rexBuilder.makeLiteral(0, intType, false)); Review comment: I am still not sure. First, the expression above does not seem right; did you mean `a.b + a.c` which would translate to `ITEM($0, 'b') + `ITEM($0, 'c')` assuming `$0` is a `RexInputRef` for `a`. Secondly, in such case, the `checkSimplify` will mainly be testing the `plus` isn't it ? ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
