Fetch out of squence error when insert query is run

Ignition

I am receiving the error below when I run the query shown below. I have disabled polling on the table component which the insert query is updating. Any help would be greatly appreciated.

Thanks

Error:

I did verify that the query does work in Oracle Developer with no fetch out of sequence error.

I don't see anything obviously wrong with the query, but I haven't used Oracle in ages. The error itself is purely coming from Oracle's JDBC driver, so you will probably need to research it through them.

This topic has some helpful information:

I suspect you need to run this in an explicit transaction.

I tried running in an explicit transaction, but still got an error. Code below is what is ran once confirmation to insert is given.

The thing that is so strange to me is that the data is inserted but the error persists.

You aren't providing the transaction ID to the named query.

SQL throws java errors, so you'll need to catch those instead:

from java.lang import Throwable

try:
    ...
except Throwable as e:
    ...

That's my bad.

Updated code below and error persists.

            try:
				tx = system.db.beginNamedQueryTransaction(db)
				system.db.runNamedQuery(path, params, tx)
				system.db.commitTransaction(tx)
				system.db.closeTransaction(tx)
			except Exception as e:
				self.error("Insert named query failed! {}".format(e), "NAMED QUERY ERROR")

I finally resolved this issue.

I had my query type set to "Query" rather than "Update Query"
