Hi,

I have created a table company, column ID as primary key and selected auto increment option. I have created the corresponding Java and DAO classed by using Hibernate Reverse Engineering. When I was saving data into my table company, its not getting saved.

As select max(Id) from company returns null, So, I have inserted a row in to table manually and next time when I tried inserting into DB using my java program, it started working fine.

So, when ever I use auto_incrment option, do I need to manually insert a row into table, so that hibernate works fine?

Please advice.

Thanks in advance,
Gupta

Gupta,

You have to do some DML commands (insert,update,delete) in transaction and you have to call transaction.commit() if you want that save data to database.

See example pattern on this thread : http://myeclipseide.com/PNphpBB2+file-viewtopic-t-16377.html
