Ok so I don't speak pearl, but when I first changed NAME##_NULL to
NAME::field_count everything compiled in the library, but it barfed in
the tests directory with:
/media1/mysql++-3.1.0/bk-deps g++ -c -o
test_null_comparison_null_comparison.o -Ilib -I/usr/include/mysql -g
-O2 ./test/null_comparison.cpp
./test/null_comparison.cpp:33: error: expected `}' before '::'
token
./test/null_comparison.cpp:33: error: expected initializer
before '}' token
./test/null_comparison.cpp:33: error: expected declaration
before '}' token
make: *** [test_null_comparison_null_comparison.o] Error 1
So I tried using NAME##_field_count and that went through just fine
including the examples.
I tested by modifying "ssqls5.cpp" to look like:
if (res.size() > 0) {
// Build a select query using the data from the first row
// returned by our previous query.
vector<bool> v(stock_field_count, false);
v[stock_weight] = true;
v[stock_price] = true;
query << "select * from stock where " <<
res[0].equal_list(" and ", &v);
// Display the finished query.
cout << "Custom query:\n" << query << endl;
This worked, but I am not sure this is what's expected.
Oh and BTW the example shows passing a vector<bool> by reference, when
the code actually wants a pointer.
