Now that the hash is built for the current record, print out the selected fields.
既然已经为当前记录构建了散列,现在就可以打印选定的字段。
If you use the standard INTO clause, the row is filled in the order of the selected fields.
如果使用标准的into子句,那么按选择的字段的次序填充行。
But use these with caution, because users tend to leave pre-selected fields as they are.
但是使用这些时要格外小心,因为用户一般不会去改这些事先选定项。
