you should drop the cursor (exec sql close name;)
But there is trouble ahead (believe me - see below)

You certainly should disable autocommit!
exec sql set autocommit to off;
otherwise you have no control over when a transaction starts and whether this
succeded.
Then at the start of your SubProgram do
bool my_transaction;
exec sql begin work;
my_transaction=!sqlca.sqlcode;

at the end:
if (my_transaction) exec sql commit work;

This should give you an idea on how to accomplish it. If not feel free to ask
me.

But (sigh) you need my NOTICE to sqlca patch applied. It's not in 7.0 but in
7.1! I don't know any other way (I'll attach the patch)

PS: You might consider applying the patch for (update where not_found) -> 100
and the cache which doubles ecpg's speed.
