Is it possible to extract table and its related columns from sql query?

Question

For example,
If query is

SELECT Orders.OrderID, Customers.CustomerName, Orders.OrderDate
FROM Orders
INNER JOIN Customers ON Orders.CustomerID=Customers.CustomerID;

I need something like below,

{
   "tableName":"Orders",
   "columns":[
      "OrderID",
      "OrderData",
      "CustomerID"
   ]
}

And

{
   "tableName":"Customers",
   "columns":[
      "CustomerName",
      "CustomerID"
   ]
}

I can extract table names and column names separately,
but is there anyway to extract table and its related columns?
or
Is it possible to extract table and its related columns in a single struct?

I think this is a good idea, but there seems no mehod, you can get table name from *ast.ColumnName.Table.String()

you need a visitor to do that
