The same problem. In a file a_sampmysql.inc there is no declaration samp_mysql_get_field ()
compiler does not find this function.

Moreover I have added in a_sampmysql.inc a line: native samp_mysql_get_field (field [], value []); expecting that it has been lost:

Код:

/* SA:MP MySQL Functions */

#if defined _sampmysql_included
	#endinput
#endif
#define _sampmysql_included
#pragma library lgw
native samp_mysql_connect(server[], user[], password[]);
native samp_mysql_select_db(db[]);
native samp_mysql_query(query[]);
native samp_mysql_store_result();
native samp_mysql_fetch_row(line[]);
native samp_mysql_get_field(field[], value[]); // <-- this added
native samp_mysql_num_rows();
native samp_mysql_num_fields();
native samp_mysql_ping();
native samp_mysql_real_escape_string(src[], dest[]);
native samp_mysql_free_result();
native samp_mysql_strtok(dest[], separator[], src[]);
native samp_mysql_close();

Then compilation is successful also a script is successfully connected to a database and makes query, but
on samp_mysql_get_field the server crashes.
How to solve this?

(sorry by my bad english)

Dont use samp_mysql_free_result();

Doesn't help

My code:

Код:

public OnGameModeInit()
{
new res = samp_mysql_connect("localhost", ####, ####);
res = samp_mysql_select_db("modbase");
printf("%d",res);
new str[128];
format(str, 128, "SELECT * FROM users WHERE nick='%s'", "vovo4ka");
printf(str);
samp_mysql_query(str);
samp_mysql_store_result();
new line[1024];
new field[128];
printf("%d ", samp_mysql_num_rows());
samp_mysql_fetch_row(line);
samp_mysql_get_field("level", field);
printf("%s ", field);
}

Output screen:

and crash

[Bardokas]

Try format(str, 128, "SELECT level FROM users WHERE nick='%s'", "vovo4ka");
Dont use * instead fields name. Maybe it will help. And level isnt null?

always FETCH ROW before you GET FIELD. Else server crashes

He does it:

Quote:

samp_mysql_fetch_row(line); samp_mysql_get_field("level", field);

level not NULL

I think a problem in a_sampmysql.inc
Function samp_mysql_get_field is not declared. Somebody can show yours a_sampmysql.inc where samp_mysql_get_field works correctly?

It's helped!
Also I correctly modify the a_sampmysql.inc where have been skipped navite samp_mysql_get_field (field [], value []);
Thanks!

But there is a new: if to use samp_mysql_get_field with different field names that it the server crash too

Код:

public LoadUser(userid,playerid)
{
new line[1024];
new field[32];
new tmp;
format(line, 128, "SELECT money, level, specID FROM users WHERE id='%d'", userid);
printf(line);
samp_mysql_query(line);
samp_mysql_store_result();
new rows=samp_mysql_num_rows();
if (rows==1)
 {
 samp_mysql_fetch_row(line);


 samp_mysql_get_field("money",field);
 tmp=strval(field);
 PLAYERS[playerid][money]=tmp;
 PLAYERS[playerid][moneytmp]=-1;
 SetPlayerMoney(playerid,tmp);


 samp_mysql_get_field("level",field);
 tmp=strval(field);
 PLAYERS[playerid][lev]=tmp;


 samp_mysql_get_field("specID",field);
 tmp=strval(field);
 PLAYERS[playerid][specid]=tmp;
 }

That memory leak is a common one, you allocate memory in a function and return the allocated memory. It's up to the caller to free it.

This means that each time you call this function you must call delete on the returned pointer : Example : static cell AMX_NATIVE_CALL n_samp_mysql_query( AMX* amx, cell* params ) { int retval; const char *query; query=pcCreateAndFillStringFromCell(amx, params[1]); retval=mysql_query(&connexion, query); //mysql_query returns 0 if success delete query; // <--- FREE MEMORY ALLOCATED BY pcCreateAndFillStringFromCell AFTER IT IS USED if(!retval) { return 1; } else { logprintf("Error in mysql_query: %s",mysql_error(&connexion)); return 0; } } And for the samp_mysql_strtok function uses the pcCreateAndFillStringFromCell function. So it is normal that Bardokas example uses so much memory. ++ Syg

I will please give mefor your pluginof that fix bug

I'm making an admin script with SA MP MySQL plugin. The old version (v0.1), didn't work good (It crashed a lot), i thought the new version (v0.13) works better, but it isn't the best too. With the old version i could reload my script, but with the new version i can't do that. Is anybody know about a new plugin version or libmysql.dll, which working stable? What libmysql.dll is good? I copied that from mysql server folder next to samp-server.exe.
Example:
- I use this to load admin commands from database, and when i reload my fs it crashes

Код:

public OnFilterScriptInit() {
	#if defined SQL_HOST
		print("+------------------------+");
		print("|  mySQL Admin Script  |");
		print("|      by      |");
		print("|    [HuN]Peti    |");
		print("+------------------------+");
		samp_mysql_connect(SQL_HOST, SQL_USER, SQL_PASS);
		if(samp_mysql_ping()==0) {
			printf("[SQLAdmin] Connection to database is alive!");
		} else {
			printf("[SQLAdmin] Can't connect to database with host: %s", SQL_HOST);
		}
		samp_mysql_select_db(SQL_DB);
		NullAllVariables();
		printf("[SQLAdmin] Loading Admin Commands' accesses...");     <==
		LoadCmdAccesses();
		printf("[SQLAdmin] Creating Timers...");
		SetTimer("CheckPings", 5000, true);
		printf("[SQLAdmin] Creating Menus...");
		CreateMenus();
		printf("[SQLAdmin] Loading Configs...");
		LoadConfigs();
		printf("[SQLAdmin] Loading Forbidden Names...");
		LoadForbidNames();
	#endif
}
new CmdAccesses[MAX_CMDS][cmdEnum];
stock LoadCmdAccesses() {
	new line[256], field[128], i=0;
	CheckSQLConnection();
	samp_mysql_query("SELECT * FROM cmds"); // Fields: Level, CMD
	samp_mysql_store_result();
	while(samp_mysql_fetch_row(line)) {
		samp_mysql_strtok(field, "|", line);
		CmdAccesses[i][LvLNeed] = strval(field);
		samp_mysql_strtok(field, "|", "");
		format(CmdAccesses[i][CMD], 256, field);
		i++;
	}
	samp_mysql_free_result();
	return false;
}

Please, help me!

Sorry, for my bad english, but i'm from Hungary .

No?
After all queries do i delete that command?

[Bardokas]

Then no more rows left, samp_mysql_fetch_row does mysql_free_result.
You need use samp_mysql_free_result(), then get only one row.

[joco96]

The situation is increasingly better. Before this, i used samp_mysql_free_result() after all queries. I do not have to make this according to these. Thanks.

What's the role of the MySQL plugin on a server?
Do you need to download the MySQL program from the MySQL Site to use the plugin?

[joco96]

I had problem with samp_mysql_free_result(). But now, i've got again...
My memory usage is growing, and then my server crashes...
