how to use setDataBuffer from OCCI for array fetches

I have a query that I'm executing on a database that returns an array of records, I read in the Oracle OCCI documentation you have to use the ResultSet::setDataBuffer() function to fetch array's of data from the db.

I just don't get what I'm supposed to give as the first two args when a database row contains multiple columns of different data? What type should I give as my buffer type?

//example, does not contain all parts, just enough to 开发者_JAVA百科demonstrate my point
    SELECT AGE, BIRTHDATE, NAME FROM PEOPLE;
    int i[10];  // Type of buffer??? Age is int, but name is a string?
    ResultSet* res;
    res->setDataBuffer(1 /*col index of first col in select statement*/, &i[0], OCCIINT, 10 * sizeof(int));

while(res->next()) { //Fetch data...}

I have searched Google for examples in vain so far. I'm hoping that someone here could help?

As per our comments, I provide a simple example using the getString(),... functions:

// Statement -> stmt
// ResultSet -> res
// Connection -> con

// pseudo code ahead !

stmt = con->createStatement(MY_SELECT, MY_TAG);
stmt->setPrefetchRowCount(NUMBER_OF_PREFETCHES); // enable bulk collect
res = stmt->executeQuery();

while(res->next())
{
    date = res->getDate(INDEX_OF_DATE);
    age = res->getInt(INDEX_OF_AGE);
    name = res->getString(INDEX_OF_NAME);

    // do something with date, age, name...
}

stmt->closeResultSet(res);
con->terminateStatement(stmt);

But I guess this is exactly what you were originally doing?
