3 strings to 1 string with strcat? - Admigo - 27.04.2013

Heey all,

I am using mysql for saving stats and i am using much stats so i need to know how i can put 3 strings into one with strcat.
My code:

pawn Код:

strcat(query,query2);
strcat(query,query3);
mysql_query(query, _THREAD_SAVE_PLAYER, 0, gSQL);//query

Will this work?

format(string),"%sSomeOtherStuff",string);

Do it like this?

I dont know if you ever used mysql but with mysql you need long strings. So that means you need to convert some strings to one.

Yes that would work.

You can also use format for this.

Example:

pawn Код:

format(query, sizeof(query), "%s%s%s", query, query1, query2);

I need a better way cause i passed the sizeof query[1000].

I wrote this thing below for myself once to create SQL query strings

pawn Код:

#include <a_samp>
#include <pointers> // <- Required! forum.sa-mp.com/showthread.php?t=311757

stock multistrcatex(dest[], dest_len = sizeof dest, const frmt[], {Float,_}:...)
{
    new num_args = numargs(), format_len = strlen(frmt);
    if(format_len < num_args-3)
    {
        print("multistrcatex() error: More arguments than the format actually assings.");
        return;
    }
    else if(format_len > num_args-3) printf("multistrcatex() warning: Too many formats.");
    new buffer[32];
    for(new i = 3; i < num_args; i++)
    {
        switch(frmt[i-3])
        {
            case 'c': format(buffer, sizeof(buffer), "%c", @arg[i]);
            case 'd', 'i': valstr(buffer, @arg[i]);
            case 'x': format(buffer, sizeof(buffer), "%x", @arg[i]);
            case 'f': format(buffer, sizeof(buffer), "%.8f", @arg[i]);
            case 's':
            {
                strcat(dest, @arg[i], dest_len);
                continue;
            }
            default:
            {
                printf("multistrcatex() error: Unknown format %c", frmt[i-4]);
                return;
            }
        }
        strcat(dest, buffer, dest_len);
    }
}

Example usage:

pawn Код:

new my_str[256], my_array[3] = {10, 20, 30};
multistrcatex(my_str, _, "sdsdsdscccccsfc", "First came ", my_array[0], ", then ", my_array[1], ", after that ", my_array[3], ", and what ", 'a', 'b', 'o', 'u', 't', " these, and ", 1234.5678, '?');

Prints:

Код:

First came 10, then 20, after that 30, and what about these, and 1234.56780000?

Imagine to do this with large strings
