Try using g_ConnectionHandle as mysql_connect

pawn Код:

#include <a_samp>
#include <a_mysql>

new g_ConnectionHandle;


public OnGameModeInit()
{
    g_ConnectionHandle = mysql_connect("host", "user", "database", "password");// replace host with host IP, user with database username, database with database name, and password with database password
    return 1;
}

Might not conflict with that error, but I think it's because you probably missed those " "
