dynamic-data

I am working on an SQL Query using pvots with dynamic columns in SQL Server (T-sql). Rather than submitting my lengthy query, I’m illustrating my problem with a simplified model. I create 2 tables: Table1 and Table2 and populate them with a few entries as follows: Table1: Col_ID1...............Col_Name 1.........................Jan-11 2.........................Feb-11 3.........................Mar-11 Table2: Col_ID2......Account.....AccountName......Amount 1...............121...........Electricity............10000 2...............121...........Electricity............20000 3...............121...

How do you dynamically allocate a 2D matrix in C++? I have tried based on what I already know: #include <iostream> int main(){ int rows; int cols; int * arr; arr = new int[rows][cols]; } It works for one parameter, but now for two. What should I do? A matrix is actually an array of arrays. int rows = ..., cols = ...; int** matrix = new int*[rows]; for (int i = 0; i < rows; ++i) matrix[i] = new int[cols]; Of course, to delete the matrix, you should do the following: for (int i = 0; i < rows; ++i) delete [] matrix[i]; delete [] matrix; I have just figured out another possibility: int rows = ...,
