How to execute e begin block code and select in zabbix database monitor using odbc?

[solaireofastora]

I can't write the exact PL/SQL block I am trying to execute, but is something like this example:

begin
null;
end;
select * from dual;

it does not work, neither in zabbix or sqlplus

the code bellow works in sqlplus, but does not work in zabbix because it does not undestand the /

begin
null;
end;
/
select * from dual;

How can I execute a begin block code (I need to execute it to process the value) and the select to retrive the value.

The code above is only a example, the point is execute a begin block and then a select query.
