My query is :

Suppose I have a main module having a number of Insert/update SQL's.
The main module calls a submodule which too has number of Insert/update SQL's. I have not specified COMMIT anywhere in either of thse modules. Now, suppose after a successful call to the submodule, my main module abends, will the updates/inserts in made in my submodule be reflected, i.e committed?



I have this query because of a situation I faced during testing my module. My subprogram abends after inserting 3 records with sqlcode -803 for the 4th record.
But I find that the 3 previous records inserted are getting reflected in my database. Also, an update I made in my main calling module is also getting reflected.
Since I have not specified COMMIT anywhere in both of my programs, any idea how this can happen?


Also, does DB2 ever automatically commit data after say N number of records, even if I haven?t specified COMMIT in the program?



Thanks a lot in advance for your valuable time.



Regards,

Ashish Gupta

Hi Ashish,

This seems to be an interesting scenario..A commit happens when it is explicitly stated or when the program terminates successfully.
But in your case, it is a sub program which has been terminated, may be this might be the reason for the data being reflected.

A clarification reqd from ur side: Did you merely saw the inserted data in the table or did u queried the inserted data? Sometimes it is possible that u can look at the data in the table but u will be unable to fetch it. If this is the case ur data is not commited.

Please keep updated us with ur progress

Thanks & Regards
Prabs
