             Summary: Check the number of input nodes(org.apache.calcite.interpreter.SetOpNode)
                 Key: CALCITE-4046
                 URL: https://issues.apache.org/jira/browse/CALCITE-4046

          Issue Type: Improvement
          Components: core
    Affects Versions: 1.23.0
            Reporter: jamie12221


 

 

 
{code:java}
public class SetOpNode implements Node {
  private final Source leftSource;
  private final Source rightSource;
  private final Sink sink;
  private final SetOp setOp;

  public SetOpNode(Compiler compiler, SetOp setOp) {
    leftSource = compiler.source(setOp, 0);
    rightSource = compiler.source(setOp, 1);
    sink = compiler.sink(setOp);
    this.setOp = setOp;
  }
{code}
 

There may be more than two input nodes. If the input is not checked, the result set is wrong.
