RE: [SPAM] SQL SERVER/ISERIES INTEGRATION

Charles, 

Per:

http://msdn.microsoft.com/library/en-us/tsqlref/ts_set-set_74bw.asp?frame=tr
ue

one cannot set it to NONE and I don't think NONE is SQL standard either.
However, due to legacy apps on the 400 not using commitment control or
journaling, NONE was introduced in DB2/400. 
Rosalie is creating and inserting into a table on the 400 so the command
should be perfectly valid (i.e. via ODBC connection).

You are correct on journaling just the table she created, that would
definitely work.  You're also right on no planning required for that
solution.

When I said planning I was really thinking of changing the application to do
it the "right" way (per SQL standards) -- establishing commitment control
boundaries, selecting which tables need journaling and which not etc.  All
good things but require planning and strategic placement.

Elvis,

Can you use SET TRANSACTION ISOLATION LEVEL NONE on SQL server???

I didn't see any mention of this being valid during my quick scan of the
documentation.


Also, just wanted to point out that the original poster doesn't need to
journal the entire library.  Just the files he is trying to write to from
SQL server.  No real planning is required.
