I have many years experience in VB6 and lesser SQl versions than 2oo5. I have a question though that I cant seem to answer. How do you get the procedure to go back to the point of filaure and contiunue? Here is my scenario.I open a cursor and loop through all DB names. For each DB, I create the needed t-sql statement to backup the DB either full or transaction log depending on the time of day. We are always adding new clients to our DB server and they autmatically get added to teh next backup whe the job runs. If the error occurs, I need to have it go to the error handler, send and email using cdosysmail and return to the while loop and continue through the process. I had it sort of working but only in the SQL &#119;indow. ONce it was scheduled as a job, it caused the job to fail. Any help would be appreciated. I have pasted the ugly version of the code below. It was much cleaner before I tried to resolve this issue.**************************--EXEC sp_updatestats goset nocount ongoalter procedure BU_DB /*PAss in the DB name and root folder at a later time.*/as declare @folder varchar(50), @path Varchar(150), @fullpath varchar(200), @date_temp varchar(20), @time_temp varchar(20), @name varchar(40), @dbname varchar(50), @BU_FileName varchar(150), @bu_type char(1), @err int /* These are used to send the message in case of a failure or success */ declare @static_msg varchar(3000),@data_info_msg varchar(8000),@closing_msg varchar(3000), @recipients varchar(350), @subject varchar(70),@from varchar(20) Select @from = 'SQLDBA@cybershift.com' Select @recipients='dpaskiet@cybershift.com' Select @static_msg = 'This email is from our test environment and should be ignored by all except for the SQL DBA.'

However, as a novice, I was unable to determine from the article just how something like this is actually implemented. I realize that this article is probably targeted toward more advanced DBAs/Developers but a short paragraph at the end of the article to help junior DBAs (and non programmers) understand how to get started with this would be excellent.

I think this is the single best thing that they could have done for the T-SQL language.WesMon, 13 Mar 2006 23:12:00 GMTWesley Brownhttp://www.sqlservercentral.com/Forums/Topic258704-163-1.aspxComments posted to this topic are about the content posted at <A HREF="http://www.sqlservercentral.com/columnists/lPeysakhovich/anerrorhandlingtemplatefor2005.asp">http://www.sqlservercentral.com/columnists/lPeysakhovich/anerrorhandlingtemplatefor2005.asp</A>Wed, 15 Feb 2006 09:11:00 GMTLeo Peysakhovich
