T-SQL datetime rounded to nearest minute and nearest hours with using functions
...en the datetime in question and a fixed point in time (0, which implicitly casts to 1900-01-01 00:00:00.000):
declare @days int
set @days = datediff(day, 0, @dt)
and then add that number of days to the fixed point in time, which gives you the original date with the time set to 00:00:00.000:

Multi-statement Table Valued Function vs Inline Table Valued Function
...ke 'C_______' then the outer query did a sub-string and int conversion. ie Cast(Substring(2, 2) as int) as CompNo. All looks good except that sql server decided to put my Cast function before the results were filtered and so I get a mind scrambling conversion error.

Using the Swift if let with logical AND operator &&

Clean code to printf size_t in C++ (or: Nearest equivalent of C99's %z in C++)
...uPTR " then what is the question?\n", a);
If you really want to be safe, cast to uintmax_t and use PRIuMAX:
printf("If the answer is %" PRIuMAX " then what is the question?\n", static_cast<uintmax_t>(a));

What should I do if two libraries provide a function with the same name generating a conflict?
...ULE lib = LoadLibrary("foo.dll");
void *p = GetProcAddress(lib, "bar");
// cast p to the approriate function pointer type (fp) and call it
(*fp)(arg1, arg2...);
FreeLibrary(lib);
would get the address of a function named bar in foo.dll and call it.

They don't require casts.
All standard collections have copy constructors. Use them.
