I am using struts framework, So I am posting this topic here.
My application insert a record in DB, while inserting it should generate a number sequence for that record. for example: today I am inserting first record, the sequence should be 2008060001 (YYYYMM0001), second record 2008060002. I am able to get up to YYYYMM, but the sequence I am unable to get it. Can any body suggest me about it. Thanks in advance. -mark
I'd suggest you create a table in your database with two rows: Year_month and seq_no. Whenever you generate a new record for your other table, look for a record in this table for the given year/month. If there is no record, insert a record for this year/month with a sequence number of "1" and return 1 as the sequence number. If there is a record, get the sequence number, add 1 to it, update the table with the new sequence number, and return the incremented sequence number to be used by the other table.
