sql - Does SET XACT_ABORT ON do anything in a stored procedure if you're NOT in a transaction? -


does set xact_abort on in stored procedure if you're not in transaction?

i'm asking stored procedure appears somehow rolling insert statement thought part of stored procedure failing not in transaction. identity of table being pushed inserted rows not there after stored procedure returns, despite fact insert unconditional , not inside transaction.

or there other reason why sql server roll insert outside of transaction?

set xact_abort on changes behavior of statement-terminating errors instead become batch-aborting errors. batch within procedure executing more stop when error encountered, rather continuing on next t-sql statement.

this has implications error-handling. statement-terminating errors allow continue , execute handling code via if @@error <> 0 block within procedure not executed. what's worse, there no way can intercept batch-abortion in t-sql code, unless there check on @@error in following batch on same connection, might not know there problem.

perhaps insert failing quietly in way still allows identityseed incremented. not uncommon...identity values reside in sql server memory cache, volatility of provides no guarantee values continuous , without gaps.

alternatively, calling context of stored procedure matters. if called within outer-scope transaction, either initiated sql server or @ application level, rollback @ outer scope rollback inner scope work, regardless of explicit transaction handling code @ inner scope. again, identity seed incremented.

try/catch blocks (available since sql server 2005) obviate need set xact_abort on.

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...
