c# - Is there a way to get size of data commited to database by LINQ query? -


i writing example program test database connection performance (mysql, oracle, mssql).

all data prepared , queued using: insertonsubmit() pushed db using:

datetime dbinsertstarttime = datetime.now; db.submitchanges() ; datetime dbinsertstoptime = datetime.now;

i able time of operation in milliseconds.

how size of data queued or written db?

the program allows user define number of data (like 10 data type a, 4 type b etc.) generated, not amount should simulate real working conditions.

therefore know how many data generated.

the datacontext has getchangeset() method returns changeset containing objects have been added, modified or removed - 1 collection each. little more linq can separate them types , count them see how many of each type there are.

also, it'snotalie notes in comments, when timing operations should use system.diagnostics.stopwatch instead of datetime; has better precision.

note:

this answer refers linq-to-sql's datacontext. using entity framework, dbcontext.savechanges() returns int indicating how many entities affected, , can use savingchanges event inspect objectstatemanager , object states way.

Java, Hibernate, MySQL - store UTC date-time -

i saw here on few related questions (like this one , of course, this one )... essentially, want store date-time utc, , let application user choose time zone wants display date-time in. since seems date-time fields affected underlying jdbc driver, wonder if acceptable way go storing utc date-time: set both mysql , application server machine utc time zone (no need separate) both mysql , jvm should pick underlying system time settings (if not instructed otherwise) use datetime table columns on mysql side use java.util.date corresponding mapping on hibernate side (i guess java.sql.timestamp used too) let application worry interpreting date-time fields - i.e. let user choose preferred time zone is ok? edit clarify - here meant refer timestamps created strictly on server (e.g.date-time of record creation). application server instantiates date objects (new date() equals current date-time on server, , time zone agnostic). if client user wants supply date searching/filte...
