do you mean I should loop through each pos till
strlen(cellTab[CellIndex].name) to find "\0"?
strlen is ok, that gives the answer itself. Just slice to that.
cellTab[CellIndex].name[0 ..
strlen(cellTab[CellIndex].name.ptr)]
could do it. or
size_t end = 0;
foreach(idx, ch; cellTab[CellIndex].name)
if(ch == 0) {
end = idx;
break;
}
auto name = cellTab[CellIndex].name[0 .. end];
anything like that
How do you suggest I do the querry build then?
how are you running it? using a lib or just generating a .sql
file?
Hi,
I'm creating a connection to the db and conn.exec(sql)
I think I'll try the foreach to find out if it works .... (
tomorrow )
if you use mysql-native, use
conn.exec("UPDATE celldata SET name=?, ...", name);
where you can make a function for name =
/// Takes the data part from a fixed length string until a null
terminator.
/// Returns: a slice of text until a null terminator or whole
string in case there is none.
const(char)[] str(size_t n)(const(char)[n] text)
{
// count until \0 (in bytes, so we can't cause utf decoding
exception)
auto end = text[].representation.countUntil(0);
// return whole string if there is no \0, otherwise until \0
return end == -1 ? text[] : text[0 .. end];
}
I think making your own function here instead of using to!string
is what you want here. If you put in a char[20] into to!string,
it will still return a string with the remaining characters being
\0 characters.
