I have been playing with mysql for quite some time, but i can't find solution for this one anywhere.
Basically i want to check how many entries are in the database for player's steamid.
PHP Code:
new liczSQL_ReadResult(Query1//here is the log error 
This gives me an error, how do I do it properly?

Modified code from some tutorial i was using for testing (it gives me an error that column is not right)
PHP Code:
#include <amxmodx>
#include <sqlx>

#define PLUGIN "Maps completed"
#define VERSION "1.0a"
#define AUTHOR "Grim"

// Ur Mysql Information
new Host[]     = "naven.com.pl"
new User[]    = "naven1_surf"
new Pass[]     = "xxx"
new Db[]     = "naven1_surf"

new Handle:g_SqlTuple
new g_Error[512]


new 
iExp[33]

public 
plugin_init() {
    
register_plugin(PLUGINVERSIONAUTHOR)

}

Load_MySql(id)
}
public 
MySql_Init()
{
    
// we tell the API that this is the information we want to connect to,
    // just not yet. basically it's like storing it in global variables
    
g_SqlTuple SQL_MakeDbTuple(Host,User,Pass,Db)
    
    
// ok, we're ready to connect
    
new ErrorCode,Handle:SqlConnection SQL_Connect(g_SqlTuple,ErrorCode,g_Error,charsmax(g_Error))
    if(

Is this
PHP Code:

Correct?
