B&S: What does "recNo" means?

[Eric Pu]

In the DBMain.java provided by Sun, There is a parameter "recNo" as in the following code.

public String[] read(int [B]recNo[/B]) throws ....
 

What does the "recNo" means? As I see, there is no such field in the database file. How can I create the recNo and where to store and identify it?

Thanks.

recNo mean simply... record number.

But how do I know the "recNo" of a record?

recNo is the relative record number in the flat file. The first record after the header information can have an arbitrary value, such as 0 or 1. All remaining records are numbered sequentially from there. If the first record is 0, then the location in the file of record recNo is

 location = (recNo*recordLength)+headerLength;
