Simple question

Is it better to use big query's and fetch

pawn Код:

new Query[200]; //Creates the Query string and the Pname
    format(Query, sizeof(Query), "SELECT * FROM `users` WHERE `User` = '%s'", ESCpName);
    mysql_query(Query);

And now fetch row (it will be very big and its very hard to script it)
Or use it like

pawn Код:

stock GetFromAccount(username[], obtaining[], holdingvar[])
{
    format(Query, sizeof(Query), "SELECT `%s` FROM `Accounts` WHERE `Username` = '%s'", obtaining, username);
    mysql_query(Query);
    mysql_store_result();

    if(mysql_fetch_row(holdingvar) == 1)
    {
        mysql_free_result();
    }
    return 1;
}

These one is easy way same like wirh DINI or DJSON but i think it will be slower than fetch row....


So what you say? what is better for server speed?

It would be better to get all the information from the database at once.

You brought up a good point, it's like Dini vs djSon - Getting the data from the source all at once, or separately, one at a time. Since we know the answer as to which is best vs them, we know which is best to your question (thought don't always apply that logic).

I afraid of lag...server will need to deal with very big cell's size's...and its using much memory....
But i guess i will gain at speed of o just get all info and then server fetch it...

You would be surprised how much data you can fetch at once. I had a database retrieving over 1000 fields for each player at the beginning of each login (I had vehicles, weapons, skins, and other things saved for each player) and while I had about 10 players online, I still did not detect any lag what so ever.

People seem to under estimate the power behind everything. For example, you may think writing a value to a file 100000 times would be fairly hard for a computer. However, it's the exact opposite. With the following code, it took only .4 seconds to write all 100000 values to the file:

pawn Код:

public OnFilterScriptInit( )
{
   new 
      File: open = fopen( "test.txt", io_write );
   ;

   if( open )
   {
      for( new i = 0; i < 100000; i++ )
      {
         fwrite( open, "2040\r\n" );
      }
   }
   fclose( open );
   return 1;
}

And with that, only a CPU spike of 3% was seen.

Load all the data and store it in to variables whenever a player logs in.

It's better to get all data at once, the only reason I created that stock function was so I could use it for additional items during game run-time and I didn't even end up using it in the end, then RealCop228 decided to copy it from my MySQL script release.
