Returning Strings - TheLazySloth - 22.01.2012

Code:

C:\Users\TheLazySloth\Desktop\San Andreas Multiplayer\Server\TLS-Windows\gamemodes\TheLazySloth.pwn(98) : error 079: inconsistent return types (array & non-array)
Pawn compiler 3.2.3664	 	 	Copyright © 1997-2006, ITB CompuPhase


1 Error.
______________________________

Could not find resulting AMX or its size is under 1byte. ( Probably due to compiler failure )

I get this error when I compile, this is the code that is causing the error...

pawn Code:

stock Load(DataType[], Stat[], For[]) {
    if(strcmp(For, "None", true) == 0) {
        #pragma unused For
    }
    if(strcmp(DataType, "serverdata", true) == 0) {
        new
            Query[128],
            Result[128];
        format(Query, 128, "SELECT * FROM serverdata LIMIT 1");
        mysql_query(Query);
        mysql_store_result();
        while(mysql_fetch_row_format(Query, "|")) {
            if(strcmp(Stat, "Name", true) == 0) {
                mysql_fetch_field_row(Result, "Name");
            }
            if(strcmp(Stat, "Mode", true) == 0) {
                mysql_fetch_field_row(Result, "Mode");
            }
            if(strcmp(Stat, "Map", true) == 0) {
                mysql_fetch_field_row(Result, "Map");
            }
        }
        mysql_free_result();
        return Result;
    }
    return false;
}

I am trying to make it so it loads single data and returning the string or value.
Can someone please help? +rep would be rewarded.

You're returning 2 types of data (1 is a string when you return "Result", the other one is a boolean when you return "false"). PAWN expects you to return the same data data type. A possible fix would be:

pawn Code:

stock Load(DataType[], Stat[], For[]) {
    new Result[128]; // Gets initialized to NULL
    if(strcmp(For, "None", true) == 0) {
        #pragma unused For
    }
    if(strcmp(DataType, "serverdata", true) == 0) {
        new Query[128];
        format(Query, 128, "SELECT * FROM serverdata LIMIT 1");
        mysql_query(Query);
        mysql_store_result();
        while(mysql_fetch_row_format(Query, "|")) {
            if(strcmp(Stat, "Name", true) == 0) {
                mysql_fetch_field_row(Result, "Name");
            }
            if(strcmp(Stat, "Mode", true) == 0) {
                mysql_fetch_field_row(Result, "Mode");
            }
            if(strcmp(Stat, "Map", true) == 0) {
                mysql_fetch_field_row(Result, "Map");
            }
        }
        mysql_free_result();
    }
    return Result; // Returns either the actual result or NULL
}

I hope that made sense, code is untested but should work fine.

What if I want the Value like for playerdata > Money ?

Edit:
NVM I know what to do for when I want Values... just strval(Load("playerdata". "Money", "TheLazySloth"));

The returning of the the Result and the Result only worked, thank you very much sir, +rep for you.

I suggest in that case you return it as a string too, then convert it to an integer where you actually need it. You can't return different datatypes in the same function.

Example:

pawn Code:

new Result[128], money;
Result = Load("serverdata", "money", "player"); // Store as a string

money = strval(Result); // Convert to integer

EDIT: Sorry didn't see your edit

No problem
