Обсуждение: Interrupt execution
hi, I using pgsql jdbc drivers to execute a particular query (web-based). Many a times it happens that the query might take time and the user hits "stop" .. in this case the pgsql-query still keeps running. Is there any way to stop it if the user "stops" transaction? Any patches/fixes/solutions for this? I think this will save a lot of hasseles dealing with crank users :) . thanks a lot for any help BTW i am using pgsql-7.2 . -- ------ Varun It is easier to write an incorrect program than understand a correct one
Hi , Can someone tell where to find the documentation for the latest JDBC sources? thanks On Sun, Jun 23, 2002 at 07:56:23PM -0700, Barry Lind wrote: > Varun, > > The latest sources support this via the cancel() method. > > thanks, > --Barry > > Varun Kacholia wrote: > > > hi, > > I using pgsql jdbc drivers to execute a particular query (web-based). > > Many a times it happens that the query might take time and the > > user hits "stop" .. in this case the pgsql-query still keeps running. > > Is there any way to stop it if the user "stops" transaction? > > Any patches/fixes/solutions for this? > > I think this will save a lot of hasseles dealing with crank users :) . > > thanks a lot for any help > > BTW i am using pgsql-7.2 . > > > > > > -- ------ Varun Satisfaction is the end of success
There is a cancel method in the statement api Dave On Sun, 2002-06-23 at 05:34, Varun Kacholia wrote: > hi, > I using pgsql jdbc drivers to execute a particular query (web-based). > Many a times it happens that the query might take time and the > user hits "stop" .. in this case the pgsql-query still keeps running. > Is there any way to stop it if the user "stops" transaction? > Any patches/fixes/solutions for this? > I think this will save a lot of hasseles dealing with crank users :) . > thanks a lot for any help > BTW i am using pgsql-7.2 . > -- > ------ > Varun > It is easier to write an incorrect program than understand a correct one > > > ---------------------------(end of broadcast)--------------------------- > TIP 3: if posting/reading through Usenet, please send an appropriate > subscribe-nomail command to majordomo@postgresql.org so that your > message can get through to the mailing list cleanly > >
hi , I cannot comprehend how to use this cancel statement? i mean how does the java thread get to know that user has canceled (stopped)the request and it is time to execute statement.cancel? Is there a function/routine which is called everytime user hits stop(i am using servlets),so that the call can be made therein? thanks On Mon, Jun 24, 2002 at 05:36:41AM -0400, Dave Cramer wrote: > There is a cancel method in the statement api > > Dave > On Sun, 2002-06-23 at 05:34, Varun Kacholia wrote: > > hi, > > I using pgsql jdbc drivers to execute a particular query (web-based). > > Many a times it happens that the query might take time and the > > user hits "stop" .. in this case the pgsql-query still keeps running. > > Is there any way to stop it if the user "stops" transaction? > > Any patches/fixes/solutions for this? > > I think this will save a lot of hasseles dealing with crank users :) . > > thanks a lot for any help > > BTW i am using pgsql-7.2 . > > -- > > ------ > > Varun > > It is easier to write an incorrect program than understand a correct one > > > > > > ---------------------------(end of broadcast)--------------------------- > > TIP 3: if posting/reading through Usenet, please send an appropriate > > subscribe-nomail command to majordomo@postgresql.org so that your > > message can get through to the mailing list cleanly > > > > > > > -- ------ Varun Why do the people who know the least know it the loudest?
This is part of the servlet api, and to tell you the truth, I don't know the answer. Did you try some of the servlet lists?

Varun, The latest sources support this via the cancel() method. thanks, --Barry Varun Kacholia wrote: > hi, > I using pgsql jdbc drivers to execute a particular query (web-based). > Many a times it happens that the query might take time and the > user hits "stop" .. in this case the pgsql-query still keeps running. > Is there any way to stop it if the user "stops" transaction? > Any patches/fixes/solutions for this? > I think this will save a lot of hasseles dealing with crank users :) . > thanks a lot for any help > BTW i am using pgsql-7.2 . > >
