I'm tasked to create a program that will run an extremely long query. That query executes well in Oracle but whenever I try to run it from VB.Net, it results to the error mentioned on the title. And also, I have noticed that when I copy my query to an SQLDataSource, it copied only certain parts and not the whole query. Is there any chance for this? Thank you!

On attempting to execute a simple query on a table (dimensions: 1,131,714,069 rows by 22 columns), I am running into the error:
[Amazon][JDBC](12080) Statement object has been closed.
Research online has unfortunately not provided much insight into this error.
I will not encounter this error each time I execute a query; so far it seems that its occurrence is unpredictable. The query that most recently caused this error looked was a very simple SELECT ... FROM ... WHERE with no subqueries and only one condition in the WHERE clause.
The query was busy for about 22 minutes before failing, however after waiting a few minutes, then running it again, it completed successfully in a matter of seconds. That being said, this kind of unpredictability and unreliability is exactly what I'm trying to prevent against.
If it helps, the IDE that I am using to connect to my Redshift database is TeamSQL.
What could be causing this error, and what steps could I take to prevent it?
I have a valid SQL query in Big Query which executes fine when run. However, Big Query tells me 'an internal error occurred and the request could not be completed' under the validator and as such I cannot save the query as a view.
Why is this? It's very frustrating and it hasn't happened with other queries I've written. I've double checked all the schema references are fully defined etc. It's been happening for the past 3 days now.
Many thanks for any help.
I'm trying to run a query in the UI, but I get the error:
Error: 6.1 - 0.0: Only one query can be executed at a time.
I don't think there is any other queries running, and this has lasted for a while now. Surely it can handle more than one query at a time?? How long will this be stuck? How can I turn bigquery off and on again :p
This error means that the query string has been parsed as containing multiple queries. Check that you do not have multiple top-level SELECT statements in the query text box.
From the specific message, I would guess your second query begins on or around line 6.
I run an update script on my SQL 7.4.27 DB. I add some constraints and change some column values.
The script is to long for posting here.
The query gives me the following error:
ERROR: could not find trigger 96099812
********** Error **********
ERROR: could not find trigger 96099812
SQL state: XX000
Where can I begin to look for the solution? The error message doesn't give me anything that could help.
7.4 (and up to 8.2 IIRC, haven't double checked in the release notes) had some plan invalidation issues in PL/PgSQL. It'd prepare a plan, then run the cached plan even if DDL had run that'd since caused the plan to make no sense.
That'd be my first suspect for this kind of issue, but it's hard to be too sure - I didn't really get started with PostgreSQL until well after 7.4 came out in late 2003. Yes, that's ten years ago.
I'd take a look in pg_trigger to see if the entry is there, but I couldn't tell you much about what its presence of absence means without seeing the code you ran.
Some of the queries I have written inside MS-Access are getting deleted automatically. And while I run the queries through code, I get this error:
Query should have one destination field
What can be the possible reason?
Explanation: I created a query in MS-access. Ran it from the code. Closed the database. Started it again, and now for that particular query, it is showing 'SELECT ;'only.
Strange. I am in panic mode now
Check if your query actually has any fields in the query design grid. When you open the query in design view, you will most likely notice it doesn't.
Does the query stick around when you don't run the code (but still close and reopen the database)?
If so, I would suspect that something in your code is overwriting the query.
