Query_sql to check if the players is online

[tmav94 1]

i have the ".@char_id". How can i apply this action (query_sql) with this var?

why use query_sql

you can use this method

.@acc_id = charid2rid(.@char_id);if (!.@acc_id){    debugmes "Char not online";    end;}//DO anything with .@char_id and .@acc_id here.(Character is Online)

This method is new for me...

Look this other two:

query_sql("SELECT login.account_id FROM login LEFT JOIN `char` ON login.account_id=`char`.account_id WHERE `char`.online=1") 

and:

if(isloggedin(getcharid(3))) 

They do the samething?

No.

getcharid(3)

Means character is attached.

you can do something like

query_sql "SELECT `account_id` FROM `char` WHERE `char_id`='"+ .@char_id +"' AND `online`=1",.@acc_id;if (!.@acc_id){//CHARACTER IS OFFLINEend;}//CHARACTER IS ONLINE

but I recommend you to use charid2rid, as its efficient as compared to executing Queries.
