QUESTION
this is the code I wrote, and I have been getting the error.
What I am trying to do is that Client have 2 child classes "CASUAL_JOB and CONTRACT_JOB" but these 2 classes have Client No (primary key of Client Table) under different Heading. So my target is to find total cost (info in Invoice Table) which is integrated with JobID (present in Invoice, Contract_Job, Contract_job Tables) and retrieve Client Info from Client Table

Answered 2020-Oct-11 at 11:00I formatted your code so it's readable. And by indenting it, you can see where the problem is. It's in line 6/7 in the "FROM" part. Oracle can't really figure out what you're trying to do with that statement and when the parser reaches the end of the query at "(+)", he tells you that there is something missing/awkward. That's why he tells you it's the "(+)". But the problem is earlier. It's the way your build your "FROM" part. It's a bit confusing, so here is just a pointers:
when using "union", you don't give an alias to each of the two queries. The result set of both queries is "unioned", so you can't reference either of them in the "WHERE" part.
You should rewrite your query and instead of joining Client with a Union, you should Union two separate queries: one joining Client with casual_jobs, one joining Client with contrac_job. Following example is done without testing it in an SQL tool:

I'm doing this table like layout with divs and flex as some styling got more complicated I had to leave "real"
One of my main issues here is that table-card
, table-card__head
or table-card__body
does not become full width to wrap the rows. I'm my example I made one of the rows to have more cells. At this point to be perfectly honest, I have no idea on why this is. I would highly appreciate pointers.

QUESTION
I coded a little game giving me suggestions what to draw. I also implemented a random difficulty, it works fine for easy and medium difficulty, but when it picks the hard difficulty it gives me an error telling me that the variable is not defined. When I run it through the vscode debugger it works perfectly fine though.
...ANSWER
Answered 2018-Oct-12 at 16:11You are generating a random number from 0 to 3. When the number is 0, the variable difficult remains undefined because none of the if clauses matches 0. So when you get to the print, variable difficult still has no value.
