Re: [GENERAL] Error with DefineSavepoint:Unexpected state STARTED

[Computer Study]

Thanks Tom.

The version of Postgres is: 9.4.7

The UI application is to add/remove some permissions through a listbox  for
a certain user. For any add/remove, it will first delete all records for
this certain user in the table, then insert the values chose from UI.

In my code snippet, it first execute the DELETE, then execute multiple
INSERT to insert selected options into the table. After all done, commit.

The server is in remote and I don't have detailed logs at this moment. Will
try to ask for that.

My question:  for that error 'DefineSavepoint: unexpected state STARTED',
not quite sure happens in which step? In the middle of DELETE or INSERT?

[GENERAL] Error with DefineSavepoint:Unexpected state STARTED

[Computer Study]

Hi,

I am working on a project of DB migration from Oracle to Postgres. The
application is working well with Oracle. But when switch to Postgres, some
SQL executionss couldn't finish and got an error like:

FATAL: DefineSavepoint: unexpected state STARTED
STATEMENT: SAVEPOINT_per_query_svp;DEALLOCATE
"_PLAN04824560";RELEASE_per_query_SVP_

The below is the c++ code to execute SQL to complete the operation. From
UI, it tries to add/remove some values (remove or insert some records into
table). When running application, nothing happens but with the error above
on DB server side. I did some search for this error, looks not too much.
Any suggestions to fix this issue?

Thanks..
