invalid types ‘int[int]’ for array subscript


Hi,

When I compile my program, it gives an error at the line:

statement->setInt(2,id[i]);

program.cc:261: error: invalid types ‘int[int]’ for array subscript

id[] and i, both are defined as int.

Any suggestions?

> statement->setInt(2,id[i]);

well there is obviously nothing wrong with that line in that amount of context. how about posting the entire function that that line of code belongs to (including the declaration of id[])

Sure, if that helps....I get the same error for each line where I use
stmt4->setInt(X,id[i])
I define the statement stmt4 in the constructor, and id[i] is defined as int - global.

void Mine::check_in_suffix()
{
int support;
long long time;
ResultSet *rs;
try{
stmt4->setInt(1,GAP);
stmt4->setInt(2,id[1]);
stmt4->setString(3,tracename[1]);
stmt4->setInt(4,id[2]);
stmt4->setString(5,tracename[2]);
stmt4->setInt(6,id[3]);
stmt4->setString(7,tracename[3]);
stmt4->setInt(8,id[4]);
stmt4->setString(9,tracename[4]);
stmt4->setInt(10,id[5]);
stmt4->setString(11,tracename[5]);
rs = stmt4->executeQuery();
while (rs->next()!=0)
{
support = stmt4->getInt(support);
.....
}
stmt4->closeResultSet(rs);
}
catch(SQLException &oraex)
{
cout << "Error executing statement in CMiner::check_in_suffix: " << oraex.getMessage() <
< endl;
stmt4->closeResultSet(rs);
}
reset_suffix();
time = rdtsc1() - time;
cout << "Time: chk_in_suffix() - "<< time << endl;
}

i have a feeling im gonna feel pretty stupid when i am done, but i sure dont see what the problem is.

what happens if you replace the array[] with just an integer? does it compile then?

Question

Yes, it compiles at other places where I use an int.

I tried
i = id[1];
stmt4->setInt(2,i);

and now it gives me an error at i = id[1]; so its not the stmt class, then what is it??!!

ohh, I should've mentioned!
i is int, just declared int i; in the function.

is
void Mine::check_in_suffix()
the function we are dealing with here? i dont see int i declared or used in that function. or are we talking about a different unposted function. or are we talking about this function but with different code???

I made the change to the code I posted earlier After I posted it, I changed it as shown below:

void Mine::check_in_suffix()
{
int support;
long long time;
ResultSet *rs;
int i;
try{
stmt4->setInt(1,GAP);
/**************************************** Following 2 lines changed/
i=id[1]; // line with error
stmt4->setInt(2,i);
/**************************************** end of change/
stmt4->setString(3,tracename[1]);
stmt4->setInt(4,id[2]); // line with error
stmt4->setString(5,tracename[2]);
stmt4->setInt(6,id[3]); // line with error
stmt4->setString(7,tracename[3]);
stmt4->setInt(8,id[4]); // line with error
stmt4->setString(9,tracename[4]);
stmt4->setInt(10,id[5]); // line with error
stmt4->setString(11,tracename[5]);
rs = stmt4->executeQuery();
while (rs->next()!=0)
{
support = stmt4->getInt(support);
.....
}
stmt4->closeResultSet(rs);
}
catch(SQLException &oraex)
{
cout << "Error executing statement in CMiner::check_in_suffix: " << oraex.getMessage() <
< endl;
stmt4->closeResultSet(rs);
}
reset_suffix();
time = rdtsc1() - time;
cout << "Time: chk_in_suffix() - "<< time << endl;
}
