Hi everybody,

 

I want do function in game source ( mysql query select )

 

my function

    int _mysql_query_select( lua_State* L ){
        SQLMsg *msg = DBManager::instance().DirectQuery(lua_tostring(L, 1));

        if (msg->uiSQLErrno != 0)
            return 0;
    
        MYSQL_RES *res = msg->Get()->pSQLResult;
    
        MYSQL_ROW row = mysql_fetch_row(res);
    
        if (!row)
            return 0;

        lua_pushstring(L, row);
        
        return 1;
    }

questlua_global.cpp: In function 'int quest::_mysql_query_select(lua_State*)':
questlua_global.cpp:1207: error: cannot convert 'char**' to 'const char*' for argument '2' to 'void lua_pushstring(lua_State*, const char*)'

Is any way to get result from query without loop?

You have to convert the result to something acceptable for lua. Mine does it.

If you need something in particular, just write the complete request here.

NB: In your code, you're trying to push the list of all the fields of your row as string. (this is clearly not possible using a direct way like yours)
