Hi all,
In my application the primary key(varchar2) of a table is like"student123",where student is same but 123 is following a sequence for each new row.For example the primary key of the next row will be "student125" and so on. How should I write my generator class to yeild such value.Please give some suggestions.

With regards,
Ajse

Extend AbstractPostInsertGenerator.

Use extra table to generate you sequence numbers - 123, 124, ...
When inserting into table set trigger to also insert something into sequence generator table. Then simply pull that last sequence generated number out and concatenate it with your 'student' string.

But there are many options. Just look at the IdentifierGenerator and its implementations for some idea.
