How to store data from a column in a variable? I'm making a command to rename the player and I need to check if his name is the same to others players

I'm not sure what you are literally asking for, but if you ask how to check if some name exists in database's player's table, let's query this

PHP код:

SELECT * FROM Players WHERE Username = '<Player Name>' 


Anyways I prefer you to see documentation of samp mysql.

`SELECT * FROM table_name` will fetch ANY column. Do not use this unless you want to retrieve everything for a player.

There is `COUNT` aggregate function which returns a 0/1 in your case.

You still execute 2 queries to check and update. All this can be done in 1 query using the keyword `IGNORE` and affected rows. Set the column for username as UNIQUE KEY and then execute your update query:

pawn Код:

UPDATE IGNORE table_name SET ...

after executing the query, check how many rows were affected. If it is 0, this means there is a player with this name and hid the warning (for duplicate) as it was instructed to (by the keyword `IGNORE`). If the affected rows is 1, it updated the new name.

I'm making a command to change the name of the player using SetPlayerName, but first I need to see if his name is not the same as the others

Thanks, and how do I send a message to the player warning that it did not work?

Anyone help?

PHP код:

forward OnPlayerDataLoaded(playerid);
 
public OnPlayerConnect(playerid)
{
    new query[128], pname[MAX_PLAYER_NAME];
    GetPlayerName(playerid, pname, MAX_PLAYER_NAME);
    mysql_format(MySQL, query, sizeof(query), "SELECT * FROM `players` WHERE `Name` = '%e' LIMIT 1", pname);
    mysql_pquery(MySQL, query, "OnPlayerDataLoaded", "d", playerid);
    return 1;
}
 
public OnPlayerDataLoaded(playerid)
{
    //Query processed, you can now execute cache functions (like cache_get_row) here.
    new NumRows = cache_num_rows();
    printf("There are %d players with the same name.", NumRows);
    return 1;
}
