Mysql- getting number of entries.
|
#1
|
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 licz= SQL_ReadResult(Query, 1) //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(PLUGIN, VERSION, AUTHOR) set_task(1.0, "MySql_Init") // set a task to activate the mysql_init register_clcmd("say check","check") } public check(id) { 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(SqlConnection == Empty_Handle) // stop the plugin with an error message set_fail_state(g_Error) new Handle:Queries // we must now prepare some random queries Queries = SQL_PrepareQuery(SqlConnection,"CREATE TABLE IF NOT EXISTS surf (name varchar(34), czas double, fps INT(5), mapa varchar(64),steamid varchar(64))") if(!SQL_Execute(Queries)) { // if there were any problems SQL_QueryError(Queries,g_Error,charsmax(g_Error)) set_fail_state(g_Error) } // close the handle SQL_FreeHandle(Queries) // you free everything with SQL_FreeHandle SQL_FreeHandle(SqlConnection) }
public plugin_end() { // free the tuple - note that this does not close the connection, // since it wasn't connected in the first place SQL_FreeHandle(g_SqlTuple) }
public Load_MySql(id) { new szSteamId[32], szTemp[512] get_user_authid(id, szSteamId, charsmax(szSteamId)) new Data[1] Data[0] = id new licz; //we will now select from the table `tutorial` where the steamid match //format(szTemp,charsmax(szTemp),"SELECT * FROM `tutorial` WHERE (`tutorial`.`steamid` = '%s')", szSteamId) format(szTemp,charsmax(szTemp),"SELECT count(*) from `surf` WHERE `steamid` = '%s'", szSteamId) SQL_ThreadQuery(g_SqlTuple,"register_client",szTemp,Data,1) //client_print(id, print_chat, "Licz: %i", licz) //client_print(id, print_chat, "o: %s", Data) }
public register_client(FailState,Handle:Query,Error[],Errcode,Data[],DataSize) { if(FailState == TQUERY_CONNECT_FAILED) { log_amx("Load - Could not connect to SQL database. [%d] %s", Errcode, Error) } else if(FailState == TQUERY_QUERY_FAILED) { log_amx("Load Query failed. [%d] %s", Errcode, Error) } new id//, licz[512] ; id = Data[0] client_print(id, print_chat, "%s", Data) /*while(SQL_NumResults(Query) > 1) { licz ++; client_print(id, print_chat, "%i", licz) client_print(id, print_chat, "%s", Query) }*/ if(SQL_NumResults(Query) < 1) { //.if there are no results found new szSteamId[32] get_user_authid(id, szSteamId, charsmax(szSteamId)) // get user's steamid // if its still pending we can't do anything with it if (equal(szSteamId,"ID_PENDING")) return PLUGIN_HANDLED //new szTemp[512] // now we will insturt the values into our table. //format(szTemp,charsmax(szTemp),"INSERT INTO `tutorial` ( `steamid` , `exp`)VALUES ('%s','0');",szSteamId) //SQL_ThreadQuery(g_SqlTuple,"IgnoreHandle",szTemp) } else { new licz= SQL_ReadResult(Query, 1) //here is the log error client_print(id, print_chat, "%i", licz) // if there are results found //iExp[id] = SQL_ReadResult(Query, 1) } return PLUGIN_HANDLED } //SQL_ReadResult(Query, SQL_FieldNameToNum(Query, "pierwsza"), szText, 127); /*public Save_MySql(id) { new szSteamId[32], szName[32], szTemp[512] get_user_authid(id, szSteamId, charsmax(szSteamId)) // Here we will update the user hes information in the database where the steamid matches. format(szTemp,charsmax(szTemp),"UPDATE `tutorial` SET `exp` = '%i' WHERE `tutorial`.`steamid` = '%s';",iExp[id], szSteamId) SQL_ThreadQuery(g_SqlTuple,"IgnoreHandle",szTemp) }*/
public IgnoreHandle(FailState,Handle:Query,Error[],Errcode,Data[],DataSize) { SQL_FreeHandle(Query) return PLUGIN_HANDLED }
public client_putinserver(id) { Load_MySql(id) }
public client_disconnect(id) { //Save_MySql(id) }
Is this
PHP Code:
format(szTemp,charsmax(szTemp),"SELECT count(*) from `surf` WHERE `steamid` = '%s'", szSteamId)
Correct?
