QUESTION
I need to get the generated id out from an oracle INSERT statement with RETURING INTO and subsequently access that value through zend framework paramContainer object.
If the id number is bigger than 3 digits I get this error:
ORA-06502: PL/SQL: errore : buffer della stringa di caratteri troppo piccolo di numero o valore
This is the zend-framework part:
ANSWER
Answered 2022-Mar-02 at 09:07ORA-06502 can be result of you trying to execute a statement that resulted in an arithmetic, numeric, string, conversion, or constraint error.
- You tried to assign a value to a numeric variable, but the value is larger than the variable can handle
- that's what you reported
- You tried to assign a non-numeric value to a numeric variable and caused a conversion error
- that what smells wrong here
If you managed to make it work using substr, is it possible that value returned by the insert statement is actually a string (e.g. 123A) which can't fit into a NUMBER datatype variable?
Because, there's no problem in storing a 4-digits number into a non-constrained NUMBER datatype variable.

I'm trying to list all the permutations of the first N natural numbers (N <= 6) with MSVC Assembly 8086 inline. I can't change anything of the C program, I can only manage the assembly code. So this is what I've done (and works with N <= 3), using the lexicographic algorithm:

QUESTION
I'm trying to write a program, in which i have to delete and insert elements in a linked list. I have problems when I delete and after that insert. In particular if i print the list after delete-insert, i print a loop. And also, if i delete the first element i think i delete the entire list.
These are the two function, but i don't know where it's the problem (sorry for the italian comments)

QUESTION
I'm trying to figure out this task, but after trying and trying i am not able to solve it. Can someone with more SQL experience help me out?
I have 3 tables:
[
The task is to calculate the average age (alter) from each person who visited a restaurant located in Salzburg. If a person visited a restaurant that is located in Salzburg twice, it should be added to the average age (Emily in this case).
Since Piccolo and Stella are located in Salzburg, 4 visits happen overall.
But how do i pull this off in SQL?
How do i count the visits?
Any help is appreciated. Thanks in advance everyone!

Was able to find the solution on my own more or less, although the answer from @Nick is awesome as well, which is why i accept his answer as correct. Thank you all so much and @Nick! Just in case someone runs into the same issue, my final solution is:

Answered 2020-Jun-12 at 10:38Since you want to calculate the average age of all visitors (regardless of whether a person visits a pizzeria in the same city twice), you can just JOIN your visits table to the pizzeria and person tables and average the results:
QUESTION
I have made a game similar to the drinking game piccolo where you have a list of challenges. Each challenges has variables that need to be filled in (e.g: Player X gives four sips to Player Y). Besides that, a challenge consists of rounds, with each round having an index and a description (e.g Round 0: X and Y drink 4 sips. Round 1: X and Y drink 5 sips now), with X and Y being the same names in both rounds.
First we made a small console app that had the challenges hardcoded in them. The list of challenges would look like this:
