How can I convert this SQL to R39+?

PHP код:

            while(mysql_fetch_row_format(Query,"|"))
            {
                mysql_fetch_field_row(DupekeyString[playerid][DupekeyCount[playerid]], "dupekey");
                format(DupekeyName[playerid],126,DupekeyString[playerid][DupekeyCount[playerid]]);
                DupekeyCount[playerid]++;
            }

mysql_fetch_row_format fetches the row and splits the result using the delimiter |
Since while loop is used, it means it moves to the next row as you select more than 1 row.

A SELECT query with the "dupekey" column:

pawn Код:

mysql_format(connectionHandle, query, sizeof query, "SELECT dupekey FROM .. WHERE ...", ...);
mysql_tquery(connectionHandle, query, "OnPlayerDupekeyLoad", "i", playerid);

Alter the rest (table name, column names at WHERE clause).

Now you want to retrieve the value in the callback specified (always a public function + forward).
We'll also use a loop as in the old code in case it retrieves multiple rows and counts:

pawn Код:

forward OnPlayerDupekeyLoad(playerid);
public OnPlayerDupekeyLoad(playerid)
{
    // cache_num_rows() is a macro
    for (new i = 0, j = cache_num_rows(); i < j; i++)
    {
        // mysql_fetch_field_row -> cache_get_field_content  
        // native cache_get_field_content(row, const field_name[], destination[], connectionHandle = 1, max_len = sizeof(destination));
        cache_get_field_content(i, "dupekey", DupekeyString[playerid][DupekeyCount[playerid]], connectionHandle, 126);
        strcpy(DupekeyName[playerid], DupekeyString[playerid][DupekeyCount[playerid]], 126);
        DupekeyCount[playerid]++;
    }
}

After assigning the text to DupekeyString, you copy the text over to DupekeyName. Strcpy (a macro of strcat) is better than format:

pawn Код:

#if !defined strcpy
    #define strcpy(%0,%1) strcat((%0[0] = '\0', %0[0]), %1)
#endif

thanks, worked now but I have another problem.

When I open the dialog for the first time, it shows no problem but whenever I open it for second time or third or more, it doubles up (example below)

PHP код:

/* What I mean is like this (dialog):
Username 1
Username 2
Username 3
Now when I reopen the dialog 2nd time:
Username 1
Username 2
Username 3
Username 1
Username 2
Username 3
and so on.
*/
                case 6:
                {
                    if(strcmp(House[tmpid][tmpowner], PlayerName(playerid), false) && PlayerInfo[playerid][power] < 4) return SendClientError(playerid, "You don't own this house!");
                    {
                        new Query[256];
                        mysql_format(sqldb, Query, sizeof Query, "SELECT * FROM `HouseKeys` WHERE `houseid` = '%d'", tmpid);
                        mysql_tquery(sqldb, Query, "OnPlayerDupekeyLoad", "i", playerid);
                        new laststring[400],string[400];
                        for(new i = 0; i < DupekeyCount[playerid]; i++)
                        {
                            format(laststring,sizeof(laststring),"%%s\n",laststring,DupekeyString[playerid][i]);
                        }
                        format(string,sizeof(string),"{FF0000}[+] {FFFFFF}Create a new key\n");
                        strcat(string,laststring);
                         ShowPlayerDialog(playerid,3001,DIALOG_STYLE_LIST,"Manage Duplicate Keys",string,"Select","Cancel");
                         return 1;
                    }
