What is the proper way of getting a
std:string out of a Pro*c/C++
If I try either of the following, g++ complains:
VARCHAR some_column; std::string x(std::string(reinterpret_cast<char const*>(some_column.arr), some_column.len); std::string y((char const*) some_column.arr, some_column.len);
Basically you can’t.
Read it into a character array which is big enough to hold the value.
Add one additional character to the array size, and initialize it to 0, so that you have a c string.
After loading it, into the character buffer, assign it to the string.
