MySQL Explode Reader - vection - 10.09.2010

Guys, i have been looking for some way to read from MYSQL.
And i try with explode.
The problem is When i use this code :
pawn Код:
new sscanfinput[64], string[128];
     new name[24],
      Escape[2][128];
     GetPlayerName(playerid, name, 24);
     mysql_real_escape_string(name, Escape[0]); // This function makes sure you don't get MySQL injected. Read about it by searching it on ******.
     mysql_real_escape_string(sscanfinput, Escape[1]);
     format(string, 128, "SELECT * FROM `playerinfo` WHERE user = '%s' AND password = '%s'", Escape[0], inputtext);
     mysql_query(string);
     mysql_store_result();
     if(!mysql_num_rows()) {
           mysql_free_result();
           SendClientMessage(playerid, COLOR_PURPLE, "Your password is wrong or your account doesn't exist.");
           return 1;
     }
     SendClientMessage(playerid, COLOR_PURPLE, "You're logged in.");
     new Data[80], ExplodeSplit[3][100], MyPassword[64], MyUserName[24];
     mysql_fetch_row_format(Data, "|");
     explode(ExplodeSplit, Data, "|");
     strmid(MyUserName, ExplodeSplit[0], 0, strlen(ExplodeSplit[0]), 255); 
     strmid(MyPassword, ExplodeSplit[1], 0, strlen(ExplodeSplit[1]), 255);
     PlayerInfo[playerid][pLevel] = strval(ExplodeSplit[2]);
     mysql_free_result();
     return 1;
^
this code working good, but if i change it to more fields like that:

pawn Код:
new sscanfinput[64], string[128];
     new name[24],
      Escape[2][128];
     GetPlayerName(playerid, name, 24);
     mysql_real_escape_string(name, Escape[0]); // This function makes sure you don't get MySQL injected. Read about it by searching it on ******.
     mysql_real_escape_string(sscanfinput, Escape[1]);
     format(string, 128, "SELECT * FROM `playerinfo` WHERE user = '%s' AND password = '%s'", Escape[0], inputtext);
     mysql_query(string);
     mysql_store_result();
     if(!mysql_num_rows()) {
           mysql_free_result();
           SendClientMessage(playerid, COLOR_PURPLE, "Your password is wrong or your account doesn't exist.");
           return 1;
     }
     SendClientMessage(playerid, COLOR_PURPLE, "You're logged in.");
     new Data[100], ExplodeSplit[4][100], MyPassword[64], MyUserName[24];
     mysql_fetch_row_format(Data, "|");
     explode(ExplodeSplit, Data, "|");
     strmid(MyUserName, ExplodeSplit[0], 0, strlen(ExplodeSplit[0]), 255); 
     strmid(MyPassword, ExplodeSplit[1], 0, strlen(ExplodeSplit[1]), 255);
     PlayerInfo[playerid][pLevel] = strval(ExplodeSplit[2]);
     PlayerInfo[playerid][pAdmin] = strval(ExplodeSplit[3]);
     mysql_free_result();
     return 1;
its not working . Like here, i just add one field and its stop to read it. What i did wrong?

Re: MySQL Explode Reader - vection - 10.09.2010

I found the problem, i think its this part: new ExplodeSplit[4][100];
I have 204 fields, and when i change it to : new ExplodeSplit[204][100];
its not working well, actually its not continue with the load, its just stop there. so how i can fix it ?

I'd recommend using sscanf2 for this. It has the ability to assign values to the elements in an enum straight away.

pawn Код:
new 
    Data[512]; // Long rows need a lot of storage, so make sure your array is big enough.

mysql_fetch_row_format(Data, "|");
sscanf(Data, "e<p<|>s[24]s[64]ii>", PlayerInfo[playerid]); 

/*
e = start enum
p = specify the delimiter ( "|" )
s = defines string (username, pass)
i = defines integer. (player level, admin level, money, etc)

Read sscanf thread for more info
*/

pawn Код:
new
         Data[512]; // Long rows need a lot of storage, so make sure your array is big enough.
     mysql_fetch_row_format(Data, "|");
     sscanf(Data, "e<p<|>s[40]s[40]iiiiiiiiiiiis[40]iiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiffiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiis[40]s[40]s[40]s[40]s[40]iffffiffffiffffiiffffffffifffffffffffffffiiis[40]s[40]s[40]s[40]s[40]ffffiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiis[40]>", PlayerInfo[playerid]);
Didnt work .

UPP why the expload code with [204][100] doesnt work..

Re: MySQL Explode Reader - vection - 11.09.2010

WHY THE PROBLEM IS IN new ExplodeSplit; , IF I CHANGE IT TO new ExplodeSplit[204][1];
ITS LOAD, BUT ITS LOAD ONLY 1 NOTE!
AND IF I CHANGE IT TO new ExplodeSplit[204][200];
ITS NOT LOAD AT ALL!
