> when I try to execute sql like (insert into example_table (column1,column2)
> values (value1,value2),(value1,value2)), it will failed with error message
> like this: column "EXPR$0" of relation "example_table" does not exist. I find
> the reason is that when converting SqlNode(insert sql) to
> RelNode(TableModify), one of the steps is to change the column that stored in
> RelDataType from the fake column name (like "EXPR$0") to the real column name
> (like "id"). But when the values part in sql is more than one , the step
> above-mentioned will skip because the RelNode is instance of LogicalUnion
> instead of Project, the code refered to org.apache.calcite.tools.RelBuilder
> line 1461:
> if (input instanceof Project && fieldNames != null) {
> // change the column name
> }
