Oracle blocking repeated inserts
Oracle blocking repeated inserts
Consider a system that has multipile requests for course enrollments
coming in. We need a way to block duplicate enrollments in the system. I
created a trigger as follows, but when I get two requests from different
connections at the same time (ms apart) they are both inserted. What am I
doing wrong
create trigger enrollment_duplicates
before insert
on enrollment
for each row
begin
select count(*) into cnt from enrollment where user = :new.user and
course = :new.course and status = 'Enrolled';
if cnt > 0 then
raise_application_error(-20001, 'User already enrolled in course');
end if;
end;

How to return a dynamic allocated struct of arrays in a method?
How to return a dynamic allocated struct of arrays in a method?
I have the following struct and method in the public part of my headerfile:
struct InputtedInstructions
{
string name;
string arg1;
string arg2;
string arg3;
};
InputtedInstructions get_instruction(vector<string>& text, int count);
then in my cpp file:
Instructions::InputtedInstructions
Instructions::get_instruction(vector<string>& vec, int counter)
{
int ListPosition = 0;
InputtedInstructions* InputList = new InputtedInstructions[counter];
while (ListPosition != counter)
{
string text = vec.at(ListPosition);
istringstream iss(text);
string command, arg1, arg2, arg3;
int CommaAmount = count(text.begin(), text.end(), ',');
if (CommaAmount == 2)
{
while( iss >> command >> arg1 >> arg2 >> arg3)
{
InputList[ListPosition].name = command;
InputList[ListPosition].arg1 = arg1;
InputList[ListPosition].arg2 = arg2;
InputList[ListPosition].arg3 = arg3;
ListPosition++;
}
}
//same thingfor 3 commas, 4, etc.
return InputList;
My issue is on that return statement down there. it wants me to add [] to
the end of it. but I want to return the entire InputList array. Is there
something glaringly obvious I am doing wrong? Thanks for your help.
