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

             Summary: Incompatible types: org.apache.calcite.sql. parser.Span 
can not cast to org.apache.calcite.sql.parser.SqlParserPos
                 Key: CALCITE-4442
                 URL: https://issues.apache.org/jira/browse/CALCITE-4442
             Project: Calcite
          Issue Type: Bug
          Components: core
    Affects Versions: 1.18.0
         Environment: Here is my code:
{code:java}
// code for parserImpls.ftl
SqlAlter SqlAlterTableRename(SqlParserPos pos, String scope) :
{
    final SqlIdentifier oldTableName;
    final SqlIdentifier newTableName;
}
{
<TABLE> oldTableName = CompoundIdentifier()
<RENAME> <TO>   newTableName = CompoundIdentifier()
    {
        return new SqlAlterTableRename(pos,scope,oldTableName,newTableName) ;
    }
}
{code}
 

 
{code:java}

// code for SqlAlterTableRename class
package org.apache.calcite.sql;

import org.apache.calcite.sql.parser.SqlParserPos;
import org.apache.calcite.util.ImmutableNullableList;

import java.util.List;

public class SqlAlterTableRename extends SqlAlter{

    private SqlIdentifier oldTableName;

    private SqlIdentifier newTableName;

    public SqlIdentifier getOldTableName() {
        return oldTableName;
    }

    public SqlIdentifier getNewTableName() {
        return newTableName;
    }

    private static final SqlOperator OPERATOR =
            new SqlSpecialOperator("ALTER TABLE RENAME", SqlKind.ALTER_TABLE);

    public SqlAlterTableRename(SqlParserPos pos) {
        super(pos);
    }

    public SqlAlterTableRename(SqlParserPos pos, String scope) {
        super(pos, scope);
    }

    public SqlAlterTableRename(SqlParserPos pos, String scope,SqlIdentifier 
oldTableName,SqlIdentifier newTableName) {
        super(pos, scope);
        this.oldTableName = oldTableName;
        this.newTableName = newTableName;
    }

    @Override
    protected void unparseAlterOperation(SqlWriter writer, int leftPrec, int 
rightPrec) {
        writer.keyword("ALTER");
        writer.keyword("TABLE");
        writer.print(oldTableName.toString());
        writer.keyword("RENAME");
        writer.keyword("TO");
        writer.print(newTableName.toString());
    }

    @Override
    public SqlOperator getOperator() {
        return OPERATOR;
    }

    @Override
    public List<SqlNode> getOperandList() {
        return ImmutableNullableList.of(oldTableName,newTableName);
    }
}
