NULL or not NULL, that is the question - dusk - 17.11.2013

pawn Код:

GetRankName(rank,jobid,i);
        printf("Rank:%s",rank);
        if(isnull(rank)) print("Null"),format(str,sizeof(str),"%d:——\n",i);
        else format(str,sizeof(str),"%d:%s\n",i,rank);

Prints:

pawn Код:

[20:49:49] Rank:NULL
[20:49:49] Rank:NULL
[20:49:49] Rank:NULL
[20:49:49] Rank:NULL

The "print("Null")" is NEVER printed, but it is null... Any help?

isnull doesn't check if the string is equal to null, it checks if the string is empty.

Re: NULL or not NULL, that is the question - dusk - 17.11.2013

But the string IS empty. I don't use it anywhere since its' declaration, except a value from MySQL is stored in it(and the value is nothing). So I'm pretty sure it should be empty....

MySQL may be loading it as null. Formatting it to "" and printing it out to see if it says null.

Re: NULL or not NULL, that is the question - dusk - 18.11.2013

Yes, MySQL was loading null, so now if there are no rows(something I should have done at first) I return.
Thanks
