QUESTION
I am a newbie wrt functions and I am struggling with using the name of a table in the function body. I get an error "SQL Error [42703]: ERROR: column "tname" does not exist" when I call the function using
...ANSWER
Answered 2020-Oct-06 at 06:12The problem is the superfluous nested DO
statement.
The variable tname
exists only in the scope of the function, not in the nested DO
statement. DO
is an SQL statement, not a PL/pgSQL statement, and there are no variables in SQL. Also, DO
does not allow parameters.
Get rid of the DO
and you will be fine.

...ANSWER
Answered 2020-Aug-31 at 21:55Firstly, using jQuery in a Vue project is a bad practice. It will work, but this is just unnecessary overhead. Vue can do what jQuery does and arguably more. I see you are already using bootstrapVue, and therefore you don't need jQuery at all.
To answer your question, DOM updates in Vue are asynchronous. It means that when you assign this.assigntoteamform
to response.data
, and then proceed to show the modal, the DOM doesn't necessarily update in that order. There is a mechanism to wait for DOM updates before doing something, via $nextTick.
Replace what you have with

I am having an issue getting the javascript script for the executeScript nifi process to work and would appreciate help with this. The goal is to pass a flowfile which will contain a json object. I need to parse this json without knowing the content/fields prior and pass this along to write it out to the flowfile that is being passed out to the next process that is MergeContent and counts the number flowfiles. Tried testing the script and got the following error:
...ANSWER
Answered 2018-Aug-13 at 15:06I saw a couple of things here:
- I don't know if Nashorn (Java's JS Engine) supports the full lambda syntax, I was able to get it to work by making the lambda a function (see script below).
- You refer to a
json
variable to get the value from a key, but I think you wantmessage_content
. result
is not defined, so you get an error when you push to it.
Here's an edited version of your script that I got to work the way I think you want it (but please correct me if I'm wrong):
