-----------------------------------------

             Summary: SQL Calcite: ArrayIndexOutOfBoundsException when serializing MINUS_DATE operation 
                 Key: IGNITE-16799
                 URL: https://issues.apache.org/jira/browse/IGNITE-16799
             Project: Ignite
          Issue Type: Bug
          Components: sql
            Reporter: Konstantin Orlov


If you run the following test:

 
{code:java}
// ProjectFilterScanMergePlannerTest.java

@Test
public void testProjectWithDateMinusExprMerge() throws Exception {
    assertPlan("SELECT (DATE '2021-03-01' - DATE '2021-01-01') months FROM tbl WHERE c = 0", publicSchema, isInstanceOf(IgniteTableScan.class)
        .and(scan -> scan.projects() != null)
        .and(scan -> scan.condition() != null)
        .and(scan -> ImmutableBitSet.of(2).equals(scan.requiredColumns()))
    );
} {code}
, you will get the following exception:
{noformat}
java.lang.ArrayIndexOutOfBoundsException: 2
	at com.google.common.collect.RegularImmutableList.get(RegularImmutableList.java:60)
	at org.apache.calcite.rex.RexCallBinding.getOperandType(RexCallBinding.java:149)
	at org.apache.calcite.sql.type.OrdinalReturnTypeInference.inferReturnType(OrdinalReturnTypeInference.java:40)
	at org.apache.calcite.sql.type.SqlTypeTransformCascade.inferReturnType(SqlTypeTransformCascade.java:58)
	at org.apache.calcite.sql.SqlOperator.inferReturnType(SqlOperator.java:537)
	at org.apache.calcite.rex.RexBuilder.deriveReturnType(RexBuilder.java:290)
	at org.apache.ignite.internal.processors.query.calcite.externalize.RelJson.toRex(RelJson.java:472)
	at org.apache.ignite.internal.processors.query.calcite.externalize.RelJsonReader$RelInputImpl.getExpressionList(RelJsonReader.java:248)
{noformat}
 

This caused by definition of the MINUS_DATE operation:
{code:java}
public SqlDatetimeSubtractionOperator() {
  super(
      "-",
      SqlKind.MINUS,
      40,
      true,
      ReturnTypes.ARG2_NULLABLE,
      InferTypes.FIRST_KNOWN, OperandTypes.MINUS_DATE_OPERATOR);
} {code}
The return type should be inferred from the 3rd argument, but it appears after converting AST -> REX, the resulting expression has 2 arguments only.

This seems to be a bug in Calcite Framework, but we could avoid this problem by serializing the operation type for each operation.
